SEAT BELTS:REAR

i bought a brand new mazda cx-7 in july 2007. i took it to the service department on august 9th because of a loud noise from the rear interior. the dealer service department informed me that the noise was from the rear mid seat belt that retracts into the roof. they informed me that the seat belt had not been fitted correctly at the assembly plant and that the seat belt was inoperative. they ordered a new seat belt and replaced the original belt. before taking the vehicle back to the dealer i had been driving my young children in the rear seat on the assumption that the seat belt worked and my child was safe. i am concerned that if the assembly plant can fit a seat belt that is inoperative once and it passes all the plant quality checks, they can do it many more times. how many mazda vehicles have been fitted with rear seat belts that are inoperative? *jb

TIRES

mazda cx7 (fwd) exhibits abnormal tire wear(cupping,feathering) on all (4) tires after less than 1000 miles. brought the car into the purchasing dealer who re-balanced and realigned. tires continued to exhibit the same wear after 2000 miles and ride at highway speeds had some vibration and rough feel at lower speeds. dealer once again realigned vehicle and increased the psi on all 4 tires to 36psi. at just over 5000 miles vehicle was brought into dealer again, still continuing to show abnormal wear and poor ride at highway speeds (vibration & rough). dealer realigned and re-balanced all wheels and once again increased tire inflation to 36psi. i later contacted the service mgr and told him that i did not like the fact that he increased the tire pressure over the manufacturers recommended settings and that this would cause the tire to wear down the center quickly. *jb

ENGINE AND ENGINE COOLING:ENGINE:GASOLINE:TURBO-CHARGER

after short duration idol "5-10" minutes car blew heavy white and black smoke out of exhaust followed with a clanking/rattling sound from the rear of car. three time this happened in a short 4-7 mile drive home. took it to the dealer and at first the said they could not duplicate the problem but updated the engine and transmission computer program. then they let the car idol for some time and it blew the smoke and heard the sound. so they decided after calling and reporting the event to the regional manager to replace the turbo. i have looked on-line about these problems and have come across owners that have had their turbos replaced a few times and the problem still exists. when the parts are in and they replace the turbo, i will see if this is a fix. i have very little faith that this will fix the problems this vehicle has. and it has many.

ENGINE AND ENGINE COOLING:COOLING SYSTEM

while on a trip, our a/c stopped working on our 2007 mazda cx-7. this car was 1 year and 1 month old we went to the nearest mazda dealership. parts were not available, and the service tech told us that we could continue to drive the car without a/c. 200 miles later, the engine started making sounds and the car stalled in the middle of a busy road. we were able to get the car restarted and attempted to get the car off the road, and couldn't find any place to pull over, and then black smoke engulfed the car. the car "died" in the middle of a busy street with no shoulder. we believed at the time that our car had caught on fire. the car continued to emit a large amount of black smoke, we ran from the car called 911. we did not open the hood of the car thinking that there was probably a fire under the hood. by the time the police dept arrived, the smoking stopped. our car was disabled on the middle of a busy street (with no shoulder). we were very lucky that our car didn't cause any serious accidents to other vehicles while it was disabled in the middle of the road. we were left stranded with an inoperable "burnt" car 800 miles from home. our mazda roadside assistance was absolutely worthless. it turned out that the a/c "seized" up and caused the serpentine belt to "disintegrate". the car was left at mazda for 2 weeks, and the part still had not come in and was on back order. the belt was replaced and an a/c unit taken from another cx-7 so we could get our car home. how can an a/c compressor be on back order on a 1 year old model, unless this has been happening on other mazdas? i believe that this is definitely a safety issue!

the air conditioning compressor pulley bearing seized but was able to turn long enough to get to a nearby relative. the dealer said the compressor and belt would be replaced under warranty, but the part would be difficult to get and estimated at least a week or more. he supplied a loaner and said the car would not be safe to drive, as the pulley could seize completely at any time. i am still waiting for the replacement part.

ENGINE AND ENGINE COOLING

the ac on my 2007 mazda cx-7 stopped working while driving on freeway about 14 months after i bought it. i had an appointment within a couple days to bring it in for an oil change so i didn't do anything immediately. the next day, while driving locally i saw smoke coming from the rear of the car and then the power steering stopped working. i forced the car over to the side and got it towed to the nearest mazda dealer. after 2 weeks without the car, they finally fixed it saying that the belt tensioner had "frozen up" and the belt had melted onto the ac compressor and power steering drive wheel. they had to replace both pulleys and the belt with parts shipped in directly from japan. the car should not have had this major of a problem within 25k miles and less than a year and a half of driving, and i'm wondering what other damage it may have caused that will crop up in the future.

TIRES

my husband and i purchased 2 mazda cx-7's in oct 07. in sept 2008 1 vehicle after just 13,000 miles on it had excessive and abnormal wear on all 4 of the tires. we have been advised not to drive much on these tires in the condition they are in by 4 separate opinions we received from the dealership, tire manufacturer and 2 additional tire retailers. we have had 1 flat tire during the process of getting these tires replaced however neither the dealership, car manufacturer nor the tire manufacturer would stand behind the faulty equipment. all agreed that the tires should not wear that excessively however each blaming the other for the problem. several posts on the internet state the same problem with this tire and this vehicle! i feel i have the right to have safe equipment on my vehicle and i am looking for support to keep my passengers as well as other's who may be driving this car with these tires safe. i would like to mention that the other vehicle of the same make and model bought on the same day has a different tire on the car and that car has normal wear and tear.. to me this is evidence that something is not right with this car and this tire.

TIRES

i purchased a 2007 mazda cx-7 from diamond mazda in baton rouge, la. i have always been under the assumption that a set of tires on a new vehicle would last me at least till i paid off the loan which would be 5 years. i have purchased other vehicles and never had this probably before now. this is the first time that i have bought a mazda and probably my last. i am very disappointed about the run around that i am getting from bridgestone/firestone tire retailers. i was told that this mazda cx-7 is a heavy vehicle and that the tires are only warranty for 16,000 miles i have never heard anything like that before in my life. if i have to buy tires every year i will go broke. my mazda cx-7 has 16,000 miles on it and the tires are worn to where they are slick. they are very dangerous and for me to buy some new tires will cost me $750.00. i had no idea that this would have happen to me after only having the car for one year. i see there are other complaints on the same issue. there should be a recall on these tires.

EQUIPMENT

my a/c compressor gave out suddenly at about 40k. a few seconds before it happened there was a loud belt noise from my engine, and a burning smell. i had to pull over quickly to find where the sound was coming from. it wasn't until i turned off my a/c that i discovered that it was the source. i can not run the a/c without further damaging other components in my car. this is only a two year old car. mazda says they will not completely cover it, since it happened outside of the 36k bumper to bumper warranty. it has not yet been replaced. after plenty of research on forums, i observed that this is happening on most mazda cx-7's between 25k-40k miles. it happened to my friend who has the same model and year 4 days after her bumper to bumper warranty expired. she was driving down the freeway when the car started to smoke and left her stranded on the side of the freeway. serpentine belt burned all over. this could have been a very dangerous incident for me if i had not pulled over in time. i have contacted mazda about this issue and they deny that there is a problem in this model car. they say they handle it on a case by case issue. yet i have found postings in which people have had mazda cover the entire cost of this issue outside of the 36k mile warranty. mazda is only willing to cover half of the cost. yet after all my research, and all the other owners that i have discovered to have the same issue with the 2007 mazda cx-7 model, i have come to the conclusion that this is a quality control issue, not warranty. for the past two years my car has been to the dealership for multiple tsb's and recalls.

smoke started to come from the engine compartment and smelled like burnt rubber. there was no leak and all the belts looked ok. lost power steering and engine died. did not turn on and had to have it towed to the dealer. the dealer explained that this was caused by the a/c compressor and wanted to charge around $1900 (with taxes and everything). since i had an extended warranty that took care of most except $180. i would not file a complaint, except that the only other friend that has a cx-7 had the exact same problem and now looking at the internet it seems to be a widespread problem that needs to be fixed. it may be too late for me, but they should do a recall so other people could be potentially saved from harm.

TIRES

i have a mazda 2007 cx 7 with bridgestone tires. i have 25,480 miles and do not carry anything heavy. the car is usually used for local travel wih 1 person in it and no more than 2, both of us together weigh less than 300 lbs. two of my tires have to be replaced and another one within the next 1000 miles. people who have purchased this model have been complaining about tires wearing out at 22,000 miles and mazda nor bridgestone will do anything about it. this is a potential problem in which tires will blow out causing either property damage or loss of life. i have not replaced the tires yet, so they are available for insepction. people purchasing these automobiles should have been told that these tires wear out at around 22k miles, since i would have either asked to have the tires replaced or i would not have purchased the car. when you purchase tires from a auto shop, they indicate the normal wear of the tire. all new autos should have the same requirement. i think that bridgestone used inferior rubber to make these tires since the weight of the auto may have an effect on the wear of the tires.

i own a 2007 mazda cx7 with only 41k miles on it. it started blowing hot air, a/c would not work and it was making awful noise. i did some investigating online and discovered numerous complaints about the 2007 model having the exact same issue. luckily i read how people have experienced their car breaking down and inoperable when the same issue happened to them, so i took the car straight to the dealer. it is the ac compressor and will need to be replaced in order to even drive car ($1400 repair). this is a safety issue because no one would think their car was undrivable because the a/c isn't working. when the compressor goes out, it is shortly followed by smoke, bad smell and car breakdown. on the highway this is extremely dangerous. this is obviously a part defect and mazda is fully aware of the problem, yet they are doing nothing about it. an ac compressor is not supposed to last only 20k-50k miles on a car, that is ridiculous and consumers of the 2007 mazda cx-7 should not be burdened with bearing the replacement cost because we have a defective part in our car, nor should we have to be subjected to the safety hazard this defect can cause by complete breakdown of the car.

i bought my 2007 mazda cx-7 less than two years ago, with only 17,000 miles on it because it was a dealer demo for less than a year. over the weekend (saturday, july11, 2009) my air conditioning began blowing out hot air. the next day, my engine sounded as if it were sputtering, and my car began smoking and smelling like burnt rubber. this morning, 7/13/09, i immediately took my car to my local mazda dealership, and they told me my air compressor needed replacing for more than $800, and my car is not drivable. on top of that, the air compressor will take up to 3 weeks to order, and mazda will not reimburse me for a rental car or provide a comparable dealer car to drive because my 25,000 mile warranty has expired. my real concern is not the money, although it's a huge repair bill for a brand new car, but it's safety. if i'd driven my car a few more miles, i'm afraid my engine would have caught fire. --nicole ferguson, winston-salem, nc.

in march, my 2007 mazda cx-7 had an air compressor failure. i was coming off an exit ramp of a major highway when i noticed that my air conditioner was blowing hot air. i turned it off, then smelled burning rubber. immediately after, white smoke started pouring out from underneath my hood. while i was able to make it home, i was unable to drive the car any further. i took the car to my local dealer, and my car, like so many others, was out of warranty at a little over 50,000 miles. the dealer told me that the problem was my air compressor. i did research on the internet and found many other people experiencing the same issue. my dealership told me that this was a recurring problem with the 2007 cx-7, but that no recall had been issued. i was unable to get a loaner vehicle from my dealership and had to pay for a rental car. the cost of my repair was $1480, along with the car rental. i love my cx-7, but i will not buy another mazda after this vehicle. i feel very strongly that this is a major safety issue and needs to be investigated and corrected by mazda. i intend to let as many people as possible know about this problem.. i tried to contact mazda to no avail. it took my dealership a week to get the replacement parts for the new air compressor.

march 09 for the "umpteenth" time the check engine light came on; took 2007 mazda cx-7 in to dealership to have the " code " checked; this time (as multiple items were repaired or replaced while still under the 36,000 mile warranty) the code read "oxygen sensor" & i reported that i would need my a/c checked because it sounded and smelled funny plus it didn't always cool; they deferred the a/c, "didn't need any repairs, seemed fine" according to dealership; they replaced the o2 sensor at the cost of >$500.00 (this is a "common problem" with 2007 cx7/ checked online after the repair and $$$ cost); now july 19, 2009/ had driven car roundtrip 25 miles approx./ noticed smoke coming from under hood (no dash panel light/ or other indicator as to a problem)/ opened hood and smelled something burning plus lots of thick smoke; right side of front quarter panel & hood extremely hot to the touch (leaned in against it to look under hood and got burned (like touching a hot lightbulb or pot of coffee); didn't see any flames, but continued to smell smoke; car is currently outside with hood open, plus windows and sunroof open to allow the smoke that came into the cabin out; researched problem online(after learning from expensive repair march 2009) & saw all the reports re: smoke damage/ locked-up a/c compressor/ melted wiring to other engine parts/ paint damage; will be taking cx7 in to dealership for diagnostics in the am(from online complaints i get that the repair bill will probably be >$1200); why are almost all of the 2007 mazda cx-7 owners having the exact same problems and repairs & still no recall; my car "almost caught fire" because of a "known problem by mazda" and still no recall; if i had driven any longer/farther my car probably would have caught fire; please do something now, before someone gets hurt or killed because of these "known" problems. unknown property damage amount at this time (too be determined by dealership mechanics). thanks for your assistance.

i drive a 2007 mazda cx-7. driving down the interstate, i noticed my air conditioning was not as cold as it has always been. i pulled off the interstate and came to a stop where i noticed white smoke from the right side of my hood, i heard a loud and unpleasant noise as well as a horrible smell coming from my car. i was able to get the car back to my residence; however, after turning my car off it would no longer start. i had to tow my car to the mazda dealership for repair. turns out the air compressor locked up and the replacement of the air compressor is $900+. my car has not yet turned 40,000 miles. after a couple internet searches (www.edmunds.com) it seems as though this instance of the air compressor locking up and making the automobile unusable is a very common problem with my particular model and year car. all of the situations i read about were also on cars with low mileage.

we have a 2007 mazda cx-7. we were driving home from camping and started to smell this horrible burning rubber smell coming from the truck. after a few mins i started seeing smoke coming from the right side of the hood. at that time our friends called us. we had them following from camping. they said they seen alot of smoke and smelled something bad. we got off at federal way and pulled into a shell station to look and get gas. my husband lifts the hood and there is a small fire and lots more smoke coming from the a/c compressor. he then notices that the serpentine belt is almost melted threw. so we pull into a parking spot and out of the way when we heard a loud noise and snap. the belt came off. so we had to call mazda roadside service and get it towed to the auburn dealership. it was sunday night so we had to wait until monday morning to call. we had our 3 year old son with us. we thought we were buying a safe car and wouldn't have to deal with something like a small fire with 2007 safest vehicle of the year. now it turns out our warranty ended 2,000 miles ago we have 38,000 and there is nothing they will do to help, other than say its 1500 to fix your car. we are a single family income and that's alot of money to come up with. i have found out there are a hundred or so people this has happened to. why is there no recall already? it obviously causes small fires and is not safe for children. please consider recalling the a/c compressors, clutch packs, and serpentine belts. mazda must know there is a problem. they have a deal for the parts.

i was driving home on thursday, 3 sep 2009 when i heard this horrid sound coming from under the hood of my car. i noticed smoke coming from under the hood and, fortunately, i was close to my driveway so i was able to park and turn the car off. at first, i couldn't figure out the exact location of where the smoke was coming from but the smell of burning rubber forced me to leave it alone and let it sit over night. the next morning, when i started the car, i noticed that there was a really hot part on my car ... i'm not mechanically inclined but, i knew that the metal part turning a bright shade of orange is not a good thing. i have a mechanic for a neighbor and i asked him to look at my car. he immediately asked me if my a/c was on (it was on 1). once i turned it off, the sound and smoke went away but he told me that the a/c compressor is shot. being that my car is only 2 years and has only 29797 miles on it, i called mazda (usa) to see if i could take my car to the mazda dealership here in landstuhl, germany and have it fixed - as it is still under warranty. simple answer- no. i have read numerous stories on the internet about other 2007 cx-7 owners having the same problem (and how the 2008 cx-7's a/c compressor was updated, thus does not have the same issue), so mazda is aware of the problem, they've just chosen to remain mum about it. now i am in a quandry as to how to go about repairing this car. i am in a dilemma of having to repair the car but at what expense? if i do it myself, any chance of having mazda stand by the part is thrown into question when i do return back to the u.s. in 2011.

we own a 2007 mazda cx7. we took a vacation to florida from ohio. on the way back, we began to smell burning rubber. i stopped to check it out, but everything looked to be in order and nothing was leaking. we then lost air conditioning and the smell became more prevalent. minutes later, there was a loud bang from under the hood. the car basically began shutting down. all check engine lights came on. smoke from under the hook. no power steering. this happened at 1am in the hills of west virginia, and we were lucky to coast into a motel. this left us stranded at the motel, and upon opening my hood - there was coolant all over the engine bay and there were shreds of rubber from the belts that had snapped off. the shredded belts were still sitting inside the engine bay, and everything was still smoking. the cap had popped off of the radiator, which is why there was a coolant mess everywhere. we had to get the car towed to the closest mazda dealership (1 hour away). we were then left without our vehicle for a month while they were trying to retrieve parts. it was during this time that i found out this isn't an isolated incident, and i feel mazda needs to address this asap. i was driving with my wife, toddler, and infant - and this put us in a very frustrating situation. i was glad i was driving and not my wife, as it could have put her stranded somewhere. this is inexcusable that a car, with only 30,000 miles on it, would have this much damage. they need to address these faulty compressors.

TIRES

approximately three weeks ago, i noticed increasing difficulty maneuvering my car and two weeks ago, as i turned onto my street, (traveling at approximately 5 mph), my car actually slid across the intersection and into the curb on the opposite side of the street. fortunately, no pedestrians were nearby and neither my car nor i sustained any injury. curious as to why this would have occurred, my husband investigated and much to our dismay, we discovered that my bridgestone turanza tires � with just 18,800 miles on them � were bald except for the grooves that run along the circumference of the tire. at this time, we called two area bridgestone dealers who jointly consented that the tire had no tread wear warranty which further served to reinforce the fact that bridgestone is aware that the turanza is a poor quality tire not worthy of warranty. when questioned about the poor state of the tires after just 18,800 miles, they indicated, that other than the fact that the turanza was a �cheap� tire (their specific verbiage), it could also be due to poor driver habits or an out-of-alignment vehicle or both. because i am the sole driver of my vehicle and commute just 21 miles round-trip to my job via a state-maintained road with a maximum speed limit of 50 mph, poor driver habits is eliminated. furthermore, investigation also revealed that the car was, in fact, not out-of-alignment, as we have now replaced all four tires on the vehicle and confirmed that the alignment was fine. frankly, we find it nothing short of despicable that bridgestone continues to sell these tires when fully aware of its poor quality and it is particularly dishonorable that you are willing to risk peoples� lives because they are unknowingly driving on inferior, non-warranted tires.

my wife was driving our 2007 cx-7 with approximately 28k miles along a four lane major road when car lost power and became basically undriveable. leaving her sitting on a extremely busy section of road with my 2 year old son in the back seat as people are flying off an entrance ramp from aberdeen proving ground. she fought it to the shoulder of us route 40 north of baltimore, leaving her in a very dangerous situation. mazda dealership where vehicle was purchased was less than a half mile from failure location and after traffic had died down i was able to limp vehicle to dealer with wife following me at 10 mph. turbocharger failure has been blamed, as usual mazda has denied warranty work due to engine sludge, even though vehicle has been maintained. after thorough research for the last month, while my vehicle has sat at the dealership, via many websites edmunds forum, mycx7.com, mazdas247.com etc. mazda is claiming same engine sludge is cause of failure of numerous timing chains, turbos, vvt actuators etc. even on vehicles that have been maintained by their dealerships. there has been a technical service bulletin released by mazda (tsb# mtol - 5505) that stated the flawed design of their pcv system not allowing oil to drain properly from the turbocharger. no fix has been made available with recent information i have read in regards to the flawed pcv not circulating the oil. hope someone can bring this flawed design engine to light before someone or a family is killed in a major accident where their car leaves them stranded in the middle of a highway like i-95. thanks for the time in looking into this matter.

i own a 2007 mazda cx7 that the a/c compressor seized up on causing a near fire under the hood. i heard an awful noise and saw smoke billowing under the hood. i shut it down immediately knowing that what was about to happen couldn't be good. i went online and found out this has happened to many cx7s now the dealer is telling me that because i've owned this for 37 months, (35,000 miles) that it isn't covered by the 60,000 mile drive train warranty, (if i can't drive it, its a drivetrain problem to me)...this needs to be a class action lawsuit..or a recall you're choice.

i was driving on a snow-packed interstate highway when the car ahead of me stopped. i applied the brakes immediately. my speed was about 25 mph. the anti-lock braking system immediately responded, but my speed did not diminish appropriately. i struck the car ahead. about 20 minutes later, i tried to stop at a red light and the vehicle seemed to continue with little or no brake force actually being applied. the anti-lock system seemed overly sensitive.

my wife and i purchased a 2007 mazda cx-7 a few years ago, and over the last three months it has been in the shop with multiple problems. from an oil leak, to a bad compressor, then the timing chain gone bad and now another problem with the egr. the car has a little over 38k miles and to me it seems very odd for a car being this young in miles, to have major problems such as these. after going back and forth with the mazda corporate office, they first agreed to pay for the parts for my latest problems since i'm now out of warranty. i was fine with that until i found out the labor was over $500 to fix this problem. when i call the corporate office to try to discuss splitting the labor costs, their supervisor contacted me back with an attitude like i did something wrong and decided they were now not going to help at all. that is just poor customer service behind a vehicle that was not ready to be put on our us roadways. in my opinion, this car should be recalled. after reviewing some of the forums, many others agree with my displeasure in the problems with the mazda cx-7--check this linkhttp://townhall-talk.edmunds.com/direct/view/.f0e5b59/110. thank you. *jb

i have a 2007 mazda cx 7. i bought it new in february of 2007, so the car is only 3 � years old. two major things have happened to my car within the past two months one of which seriously put my safety in jeopardy. i will start with, two months ago, my air conditioner went out completely. the air compressor had to be replaced. then, about a week ago as i was driving down interstate 75 (going about 70 mph), the acceleration on my car completely went out. luckily i was able to get over the 5 lanes of traffic and pull the car off to the side. after i turned my car off, it never cranked again after that. long story short, i took my car into jim ellis mazda in marietta, ga and they said there was internal damage to the engine and the engine would have to be replaced completely. they couldn?t even tell me what exactly went wrong or really diagnose the problem for me. they just said the engine needed to be replaced. the kicker to this story is, when i went in a couple months ago to get my air fixed, i asked them to take a look at the engine because i thought it sounded loud. the said it was completely fine and nothing was wrong with it. well two months later this happened. i have talked to mazda customer service and they will offer no assistance for fixing my car (which i have been quoted $8,000 to fix!). i was told that mazda had reviewed my case and i was declined because there was sludge around the engine, which apparently gives then reason for no assistance. they said that is proof that my car is not maintenanced on a regular basis, however i have documented proof that it is maintenanced regularly. they just didn't seem to care.

2007 mazda cx-7. 47,000 miles. clean engine and clean oil per the service desk at the mazda dealership. pin related to timing chain broke, which caused the timing chain to break and ruined the entire engine. my car died in the middle of a very busy road and another vehicle almost collided with me as i slowly tried to move it over to the side of the road before it stopped altogether. while the company has yet to decide if they will pay for the repair since the car is under warranty, i still believe this problem should be investigated as a recall issue because of the amount of complaints i have seen online about other mazda cx-7 owners have this same issue.

2007 mazda cx-7 grand touring. (family car)! 43,636 miles(out of warranty) first off, my wife and i have a had our car serviced and oil changed every 3000 miles! and we have taken the car in numerous times for the a/c not working in over 90 degrees temperatures. and have been told by 2 dealerships that the cx-7's a/c doesn't work well over 90 degrees. living in southern california its over 90 degrees for almost 6 months of the year. a couple days ago, my wife, young daughters and i were driving our car to a destination only 3 miles from home. (the car had been sitting all day, in the garage.) we had the a/c on half way(85 degrees out). about ready to get off the freeway and only going 60 mph. the air blowing out of the a/c started blowing hot, easily over 100 degrees. the a/c started whining, though it was a belt slipping. immediately turned off the a/c and fan motor. and then began to smell burning plastic. drove 1/4 mile to destination and right before parking it, a plume of white smoke started coming out of the engine compartment and a/c vents. i opened the hood to put out the fire, i thought would be there. but the car just kept smoking with no visible flame. smoked-no it "plumed", for about 15 minutes. i called aaa , and had the car towed to a local mazda dealership. when i told the service what happened, he smiled and shook his head and told me that the a/c compressor blew. without even looking! he said, he couldn't understand why mazda has not recalled this problem yet. and that he has had a lot of upset cx-7 owners spending over $2500 because they didn't turn off the a/c when it stopped working. resulting in timing chains, blown engines and other expensive parts going out due to the stress caused on the a/c belt when the compressor blows. and if i hadn't been reading blog after blog online since 2007 when we got the car, about the a/c compressor problem, i would of been paying $2500 or more too! one day of service and $1025 later. the car seems to be fine.

after driving roughly 38,000 miles, my mazda cx-7's a/c started to have problems. it stopped blowing cold air and started to make a grinding sound. while i was driving to a place to figure out what was wrong with my car, a burning smell began to arise. it was eventually found that the compressor needed to be replaced and there were metal parts in the compressor. this caused huge damages to the car and it was estimated to cost roughly $17,000 in damages. it has yet to be fixed, but the car has only been driven for 38,000 miles and had regular maintenance intervals. there was almost no indication of what was happening because i did not turn on the a/c often.

2007 mazda cx-7 had failure of the air conditioner compressor. bearings freeze up in the compressor unit. this causes pulley to stop turning and putting pressure on the drive belt. this causes car to overheat and battery to lose charge because alternator and water pump are not spinning. they do not spin because the drive belt slips over them because air conditioner pulley has seized up. this happens around 34,000 miles and generally within months of the expiration of the 36 month warranty. internet research shows that this is a known problem to mazda. mazda refuses to cover repair under power train warranty as it is not an essential part - even though the car become undriveable.

i own a 2007 mazda cx7 and it was been at the dealer every month this summer and i'm on my second loner car. the trouble started last summer with pinging and turbo lag. that seemed to stop and the dealer said that it was a software issue. but this summer we have had three separate issues. 1. transfer case leak. fixed. 2. engine stabilizer leak. fixed. 3. variable valve timing actuator vvta. currently in shop. car loudly "growls" to life, squeaky belt, difficulty starting, told by dealer that will eventually cause engine trouble if not fixed. this has all been since july!!! we are just shy of 30k and the warranty expires next month. i am very afraid that something else will go wrong and we will end up paying for it. upon reading a few cx7 web sites and blogs, it has become clear that this vvta issue will lead to a timing belt failure and engine loss. i have a little less then 30,000 miles on this car and bought it new. unfortunately this seems to be a relatively common occurrence in the 2007 model. please issue a recall so that this defect can be addressed prior to engine failure and not at owners expense. thank you!

we have a 2007 mazda cx-7 with 67,000 miles on it. my wife was driving it on the highway, set the cruise control and moments later the engine died. turns out the problem was caused by a timing chain on variable valve timing actuator failing and damaging the engine. we have read many other people that have had issue with the timing chain and vvt. mazda is unwilling to assist us in replacing the damages. what upsets us most is my wife could have been injured or killed.

POWER TRAIN

my wife's 2007 cx7 was in a parking lot. my wife started it up, came to a stop sign and the car died without warning. it had 65,000 miles on it (5000 over the warranty) and wasn't even 3 years old. we had always gotten regular oil changes and had just had one the week before. we had it towed to the nearest mazda dealer. the first time i talked to a service tech he mentioned the timing chain breaking. later, they explained it as a valve (variable valve timing actuator?) failing and causing oil chain failure (jumping the gearing). my bill ($7500 - new engine) only states internal parts failure. they tried to indicate the oil was dirty even thought the oil was changed less than a week prior. after reading through many cx7 forums online it seems they were trying to build a case for engine sludge to cover themselves. less than 2 months later replaced intake manifold shutter valve and had to flush and reseal brake lines. went to kerry mazda of ky to originally purchase a 2008 because of low finance deals. they shifted my attention to the 2007 (3500 miles) and i agreed because of the certified new (100,000 miles) program. when i found out i didn't have 100,000 mile coverage i went back to dealer and we pulled the paperwork and under the warranty it says certified and also remainder manufacturer's warranty. so it ends up they sold me a used car as new and i didn't even get the financing of a new car - very shady. mazda corporate was of no help either, simply stating the car was out of warranty and there was nothing they could do. needless to say i will never buy mazda again. i will also make sure i don't trust what they say and make sure i read and understand every page even as they try and rush you through it. i fear someone will be killed when their cx7 suddenly stops on a busy highway. hopefully, mazda will address the problem before that happens.

2007 mazda cx-7 - a/c compressor went out (mileage 43,090 and out of warranty) on way to work on 1/4/11 around 7:30am. my car started making loud noises from the engine the day before but their were no warning signs in my car. on my way to work a lot of white smoke from my tale pipes started coming out and the noise got louder along with a burning smell and then my battery light came on and my car cut off while i was on the highway. i was lucky to coast off to the side of the road. $1250 to replace parts/tow and labor. seems this is a known issue with mazda because i have been on a lot of forums where tons of people are having the same issue. mazda on rt. 42 south jersey nj didn't mention this was a known issue. many customers have had this happen multiple times. some within the 36k btb warranty, some after. with this being a known issue, shouldn't this be a recall if it is a problem that will occur on most 2007 cx-7's with the part?

an excess of white smoke emitted from exhaust upon acceleration after a brief period of idle. it was determined that a faulty turbo charger was to blame. so the car was in the shop for 7 days while they replaced the turbo. several months later the car wouldn't start after sitting in a heated garage overnight. it sounded as though the cylinders weren't firing properly. car was towed to mechanic who identified issue as fouled cylinder heads from prior failure of turbo. this time the entire engine was replaced. again the car was in the shop for approximately seven days. some months later an oppressive amount of road noise appeared at all speeds on all road surfaces. we were directed that the tires were to blame. after replacing all 4 tires at a cost of nearly $800 the sound persisted. upon further inspection the technician found that the wheel speed sensors on the rear wheels had failed allowing water to seep in and rust rear wheel bearings. all four wheel bearings where replaced. today the vehicle is again in for engine repair to replace the oxygen sensor and a dead battery. after owning the car for 18 months it is has been in the shop for a total of approximately 4 weeks.

in april 2009 the air conditioner compressor failed on my 2007 mazda cx-7. there was approximately 49,000 miles on the car when this happened. we replaced the compressor with an aftermarket compressor because the dealer indicated it was not in warranty. some time later we received a letter from mazda extending the warranty on the compressor to 60,000 miles. in the letter mazda explained that if the compressor had already been changed they would reimburse us for the charges. the paperwork had been misplaced at the time so we did not contact mazda for reimbursement. in december 2010 my daughter was driving the car in dallas texas when she heard a noise coming from under the hood. a burning smell started coming through the vents, then smoke started coming into the car, she had to cross three lanes of traffic to get off of the road. the car stopped running before she could get off of the road. a driver stopped and helped her get the car off of the road, luckily no one was injured. she called me and told me what happened, i called for a wrecker and had the car towed to a mazda dealership nearby. the service manager called me and told me it would cost approximately $ 1,800.00 to repair the car. he also told me that the mileage had exceeded its limits for warranty. he later called and said that when the belt broke it had damaged the pulley on the crankshaft and that for the car to run properly it would also need to be replaced. i contacted the consumer division of mazda and was basically told there was nothing they could do, they extended the warranty to 60,000 miles and that the car had exceeded its warranty. it is not normal for ac compressors to fail in such a short time unless there is a defect. mazda knew this that is why they extended the warranty. mazda needs to recall these defective compressors before someone is severely injured or killed in a wreck caused by the compressor locking up.

while driving home with my a/c on, my 2007 mazda cx7 began making a terrible whining & grinding sound, followed by billows of smoke coming from under the hood. i immediately pulled off the road, turned off the car and opened the hood, which continued to smoke for some time and there was a smell of burning rubber. i burned my hand in the process. the car was deemed unsafe and undriveable and had to be towed back to the nearest mazda dealer where we had also purchased the vehicle. it was late at night, so ,the next morning i received a call from the dealer telling me the fire started with the a/c compressor, which then ignited the drive belt. that's why it smelled so awful. he said it was "burned badly". the parts were not in stock, so, they have to order new parts. so, i'm without transportation. no offer from the dealer for a rental. they also did not tell me that there was a recall on 2007 mazda cx7 a/c compressors, which i learned about by online research. i never received a letter from mazda regarding the recall. so, it turns out that many, many people are experiencing the same issue and not enough is being done about it to fix the problem. the car has less than 30k miles and recently had a full inspection by the dealer. i'm now waiting to find out if the dealer will try to get me to pay for this or if they will honor the warranty. many online complainants are being denied and are being forced to pay for this themselves. this is not right.

mazda sent a letter to report a known issue with the 2007 and 2008 cx-7 in august 2010. the a/c compressor was creating issues and mazda extended the warranty to 60,000 miles. the letter indicated that no action was needed unless you heard a strange "noise". based on my experience and those of others, the problem occurs with no warning and all of a sudden the a/c stops working and smoke begins to come from under the hood. the issue can also cause the power steering to go out and the car to stall so how can this not be a safety concern and not be considered a recall? the warranty is only extended to 60,000 miles and there are many cases where the problem does not occur until after 60,000 miles. is mazda just hoping that most will happen after 60k so they don't have to pay for the repair? i had the dealer check it during a routine service but they wouldn't repair it unless there was a "noise". while on vacation, my car a/c stopped working and started to make the "noise". then smoke started to come out from under the hood, frightening my kids in the car. we were traveling on the interstate at the time and had to find a safe place to pull aside. we barely made it to the nearest mechanic before the belt broke. my car had 65,000 miles and mazda will not pay for the cost of the repair, nor the cost to rent a car in its place. now i am out almost $1,700 for repairs and rental fees. this issue needs to be investigated. does someone have to die in an accident as a result for mazda to be held accountable?

(march/2011) light came on around 65k miles. took it into dealership and they said oil was low and yvt needed replacing. cost was around 2500. no reason why oil was low and last changed by mazda less than 7500 miles before. also full service was done at that time. (june/2011)while on highway at high speeds the car lost acceleration, emitted high pitch whirring. and became difficult to control. towed to dealership and it is being blamed on bad turbo. no reasoning behind failure other than saying oil change issues. the problem is that mazda is the only entity that has ever worked on this car at least twice per year for check ups. there also appears to be others with same reported problems to both turbo and yvt.

my car makes a rattling noise at start up. after reading the horror story's online about this car vvta going out, or the ac compressor going out and messing up the engine i took it too the mazda dealership. they said i needed a new variable valve timing actuator. this is a major problem with year make and model. so i talk to independent mechanic who has experience with mazdas and has fixed this same problem numerous times on this vehicle. he stated the problem is you can only get the part from mazda and they are still selling the defective part. why isn't someone doing something about this. this issue has caused people from losing all power while traveling at high speed on the highway. my car also has a transfer case leak which is another thing everyone else is having problems with. someone get these guys to recall this part.this is a very dangerous car!!!

i have had my 2007 mazda cx-7 for less than one year. i stopped at a red light after exiting the highway and my car engulfed in thick white smoke. i had the car towed to a local shop per my insurance company to have it checked out. the repair shop at first called to tell me it was the starter, and that it would cost 600 to fix it. come to find out that not only the starter blew, but it also ruined the alternator as well as the fuses on the battery. i was told by mazda that this is not a common occurrence. the total of the repairs is now over 1200. the vehicle has been meticulously maintained throughout its lifespan and is at 92,000 miles.

the 2.3 liter 4 cylinder l3t engine that is in my wife's 2007 mazda cx-7 has a bad variable valve timing actuator which was verified today by dual mazda of jacksonville florida. a warranty extension was issued by mazda around the 14th of january 2012 following the initial tsb (technical service bulletin) date 23 february 2011. my concern is not that mazda has acknowledged an internal engine part as being faulty, but that the part stated in the warranty extension could possibly make the timing chain go bad. mazda did not cover how, when, what rpm range, engine load, or most importantly what speed this might happen if the actuator is not replaced. the last thing anyone wants is their engine timing going out...at any speed or at anytime while moving in a motor vehicle, catastrophic engine failure will surely follow. i feel that these faulty variable valve timing actuators are an integral part of making this engine run safely and ultimately the car overall and should be looked into before its an actual incident.

this vehicle was originally purchased used by me daughter, since the failure my wife and i bought it, i replaced the faulty turbo charger and it is now back in service. though my wife has very limited faith in the vehicle at this time. the issue is that when the vehicle was taken to mazda, the dealership mechanics/service mgr stated that the engine needed to be replaced at a cost of over $8000.00. being a mechanic myself i knew that the engine ran exceptionally well but that the turbo had a burned up cartridge and needed to be replaced. in doing the work i realized that the design of the routing of oil tubing created the failure of the turbo. also, the fact that mazda does not indicate that their (any) turbo charged gasoline engine needs to be idled to cool the turbo assembly after driving before shutting off the engine. as is common practice with diesel engines and racing engines that are turbo charged. nor did they engineer and install a timer device which would do this for the consumer so that this failure would be avoided. i have read of many of these failures in the us on forums and mazda has forced most to pay for new engines when they were not needed.

our 2007 mazda cx7 suddenly lost power and i was forced to stop the vehicle in the center median of the highway, as i was unable to move to the right due to other traffic. vehicle was towed back to the dealership where problem was diagnosed as a broken pin on the variable valve time actuator (vvt). there was no prior indication of a problem with the vehicle (no warning lights) prior to the engine stopping. dealership has indicated that complete engine replacement is recommended by mazda. currently the vehicle is awaiting arrival of an adjuster from extended warranty company to see if repairs/replacement will be covered. additional online research has indicated that this is a well-document and frequently occurring problem with this make/model of vehicle, yet manufacturer has neglected to initiate a full recall. rather they issued a "service bulletin" (#01-002/08) that addresses a vvt noise when starting engine. bulletin states "some vehicles may exhibit a loud ticking noise from the variable valve timing. (vvt) this is caused by the lock pin of the variable valve timing actuator not fully engaging. heat treatment has now been added around the hole of the variable valve timing rotor lock to prevent this from happening." it is believed that had my vehicle exhibited any symptoms, i could have had the service bulletin repairs made, and the engine failure due to the broken pin would have most likely been avoided. this should have been a recall, and not addressed by a service bulletin. there is strong evidence, as discovered via the internet, that multiple cx7 vehicles have had this exact same type of failure where the vehicle has suddenly stopped running while being driven at highway speeds. this constitutes an extreme safety hazard that could possibly result in serious personal injury or death.

the timing chain in this vehicle broke while under power. we recently received a voluntary warranty extension notice (mazda calls it a special service program) that indicated there may be a problem with the engine in the vehicle, specifically elements related to the timing chain and variable valve timing. our car always rattled at startup from the day we bought it, that was our normal experience and expectation for what the car was supposed to sound like. we never knew this was a problem until a couple of weeks ago, and come to find out, our car had passed the extended coverage period provided by mazda anyway. it is and will be our contention that there is a serious design flaw in the motor of this vehicle. while our experience is that the car failed at 83k miles, many have failed sooner, and other mazda products using the same motor are affected (l3t engine, also in the speed 6 and the speed 3) it should be noted that the service interval for the timing chain had not been reached. mazda published a tsb on this problem in 2009 or thereabouts, but never contacted it's customers directly to indicate that service may be required. it is time for the ntsb to get a recall notice issued and put this issue to bed once and for all, before someone gets killed.

vehicle has a defective variable valve timing actuator (as per the manufacturers campaign letter) that causes a noise at start up and a loose timing chain. that first phase of the failure has already occurred. the next stage of the failure which hasn't happened to me yet (but has been documented by others) is that the vvt actuator eventually becomes dislodged from its pin and as a result, the timing chain breaks, causing the engine to seize instantly, causing an emergency response from the driver to attempt to get out of the flow of traffic, without warning, within seconds of the failure. the vehicle is driven on the nj turnpike, rt. 295, rt 195, etc in central nj and when the failure as described above occurs when traveling at highway speeds on busy roadways, there is a high probability of an accident occurring at the time of the failure, or as the car sits disabled on the edge of a roadway awaiting roadside assistance. the danger is not only for the occupants of the cx-7, but also for those directly behind the vehicle at the point of the vvt failing and/or the timing chain breaking. i have requested that the vehicle be repaired for over 90 days, however mazda usa continues to inform me that the parts are not available and that there no identified date of when they will be in stock. that means that they are allowing me and my family to drive a vehicle equipped with a defective original equipment part, that when it fails, may cause harm to me, my family and others. they are not considering this a matter of safety, and instead only a matter of inconvenience in that because my vehicle is now over their self determined 70,000k mileage threshold, they are not offering to fix the car. instead, they are telling me that i can pay to have it fixed. they should be warning their customers of the dangerous condition being created by their faulty components.

i was driving my mazda cx-7 on the highway around 65 mph when my car starting making a loud noise from the engine and had a sudden loss in power. so i pulled over in the next town and stayed in a motel for the night. the next day i rented a trailer from uhaul to tow the car to a mazda dealer who stated that my engine needed to be opened to properly diagnose the actual problem. per the mazda technician that inspected my car, the timing chain (vvt) was missing a pin and caused the engine to break. therefore my engine needed to be replaced. at the price it was to replace the engine, i obtained a second opinion from a non-mazda mechanic who stated that my engine also needed to be replaced. i replaced my engine at 72,127 miles, for approximately $6k, which is slightly over the 70,000 mile service notice that mazda recently put out for reimbursement from repairs related to the vvt timing chain. after i submitted my claim to mazda north american operations, my claim was denied because i was slightly over the mileage that they determined was appropriate. i would have expected mazda to be a little more understanding as it was their dealership who initially diagnosed the problem. as such, i have currently hired a lawyer to pursue reimbursement of my engine replacement cost as this part has caused several other individuals to have to replace their entire engines. my lawyer would like to know if there are more cases of the mazda cx-7 engine breaking due to timing chain failure that was also near or above 70,000 miles. please respond/comment to this post so that we may use your story/information as verification that the vvt timing chain is an issue on the mazda cx-7. *kb

i own a 2007 mazda cx-7, which i purchased in nov. 2006, brand new. over the past 2 years, i have heard a tapping noise coming from the engine compartment of the vehicle. twice in the past 9 months, the vehicle lost complete power. i asked mazda to check the vehicle and they stated that it was common, nothing to worry about. in january of 2012, i received a safety notice from mazda in regards to a possible defect part, v.v.t. component and a loose timing chain. i took my vehicle to the mazda dealership, who advised me that my vehicle contained this defective part, but stated that they were not going to repair the defective component due to the lack of receipts for oil changes and other maintenance records. the reason for the lack of receipts is because my brother-in-law, who is a mechanic, performed the oil changes and other maintenance work to the vehicle. i asked mazda if the defective part could be hazardous and they advised me it was not harzardous or dangerous. approx. 3 weeks ago, my wife ordered the necessary parts and paid for them in full. after 3 weeks, i was advised that the parts or not available. after reading numerous websites and complaints from cx-7 owners, this is happening across the country. i further read that if the v.v.t. component fails while the vehicle is being operated, the engine will immediately cease, possibly causing the operator the inability to safely manveur the vehicle off the roadway. in my opinion, this is a danger to the occupants of the mazda cx-7 and other motorists. i have not heard of any accidents being reported as a result of the defective part, but i feel that mazda is not taking the necessary measures to ensure the safety of the motorists. i feel that the matter should be taken care of by mazda before someone is seriously hurt or killed. *kb

i was heading west out of denver on interstate 70 when my car completely failed and the engine shut off. i was in the left (passing) lane and was fortunately able to pull into the median to avoid a crash at high speeds. my four-month old son was in the back seat so i was shaken and frightened for his safety, and unable to re-start the vehicle. we were stranded there for an hour waiting for a tow-truck with other cars pushing past us at very high speeds. to add insult to injury, this is a known issue for this make and model of mazda. the company does not stand behind their vehicles--instead they are discontinuing the cx-7 b/c of it's poor engineering. they also offered an extended warranty for this issue (up to 70,000 miles so my car is not covered.) if they were a responsible company they should issue a total recall of this vehicle in order to replace the timing chains. other problems with this car in the short time i had it (bought it at 53,000 and it has a dead engine at only 76,000) -mysterious electrical problems causing all gauges to go haywire when i accelerated or turned -leaking valves in the transmission (just paid $800 to have that repaired in october) -faulty air conditioning compressor (also extended warranty) basically, this car is a total lemon. if you have one that still runs--beware! if i had been 2 miles farther down the freeway i would have had no where to pull over and would have been stalled dead on the freeway in heavy traffic... with young son in the back seat.

we have a mazda cx7, 2007, that we purchased brand new in april 2007. we have had all oil, filter and other services by our local mazda dealership in accordance to mazda guidelines. recently while driving 70 mph down interstate 81 with our 10 year old son in the car, our mazda stopped working. lucky for us we were able to get off of the road and call a tow truck, who took us to a local mazda dealership where we had to leave the car until monday (it was a saturday afternoon) and find other means of transportation home (70 miles away) on monday morning my husband received a call from mazda stating that our vvt plug came apart causing the engine to jump time and that we could pay to have a vva kit ordered and installed to see if it would fix the problem, at a cost of $1300, but this may not fix the problem because due to the plug coming apart our engine lost compression. and if this was the case, we would be out the $1300 and it would cost an additional $7950 for them to replace the engine. when we questioned them about the "service bulletin" released re: the problems they were having with this vvt they said that they really couldn't help us with this.... our car was over in the mileage... well to me a problem they recognize and admit to they should take care of no matter what.. had we have know of this pending problem, we would have opted to have this kit replaced long ago and gladly paid the $1300 instead of being out a car, that we really have enjoyed, and now looking for someone to replace an engine!! oh and by the way.. don"t let mazda do this for you!! it is much cheaper to have your engine rebuilt and replaced by an outside source. we have contacted a machine shop in virginia who will pay shipping and do this for us for $3000 and we have a local mechanic that will do the work for $1000 oh and they give you a 5 year warranty!! mazda needs to be responsible.

after owning our 2007 mazda cx-7 for over 5 years, we received an extended warranty notice that the timing chain was defective and at risk of breaking. having noticed a slight ticking noise already, we immediately took it to the dealership where it was purchased. they examined it and notified us that even though our car was 5 years old and at risk of failure due to a factory defective part, the warranty was only extended to 70,000 miles and mazda would not cover any costs since our odometer was at 80,000. i went home, did some online research, and discovered that our year and make of vehicle also had a tsb from mazda for a defective timing vvt actuator that could cause the same clicking sound. we had never been notified of this by mazda or the dealership. i called mazda customer care immediately and they assured me that the timing chain was the source of the clicking noise. two weeks later the vvt actuator in question did fail. mazda assumed liability and replaced the defective vvt assembly and timing chain, but refuse to cover any of the costs to repair the severe damage caused to our engine as the direct result of this part failure.

purchased 2007 mazda cx-7 with 65,000 miles. at the time was told it had a new turbo. had the vehicle 2 months and the erg valve died (technician stated they should last 100k miles) was replaced at my cost of $850. when replacing the erg valve they also noticed a worn tube that will cost an additional $180 at my cost. they also noticed the new turbo was smoking and this was an extended warranty coverage from mazda to 70k miles (i was at 68,5000). they are adding a whole new pcv vent kit at dealer expense). now i am hearing a loud ticking noise whenever i turn on the a/c which could be either the vvt timing chain or the air conditioning system. both are known defects of 2007 cx-7's and will cost about $1,000 to fix for each issue. the timing chain is covered until 70k miles so i'm trying to get this fixed by the dealership now before i run out of warranty. however, the ac issues were only covered to 60 k miles and i am beyond that coverage so i will have to fix that at my cost. if you do a quick google search you will see extensive documentation of these same issues amongst many mazda owners. mazda refuses to recall such parts and only this year (4-5 years later) did they extend warranty coverage on some known defects knowing that most people would be beyond the warranty limit of 60/70k miles. there are many reports of engines seizing due to the ac and timing chain issue. i am quite frankly terrified to drive this car and seeking a very comprehensive extended warranty to hold me over until i can trade it in and get something reliable! i work for a car dealership so i know that these issues are legitimate with this vehicle.

after six months, we began to have mechanical issues with the vehicle. a diesel-sounding chug coming from the engine seemed off for an unleaded four-cylinder suv. the common issue seemed to be a part called a vvt actuator. no recalls or service advisories had been issued for engine parts at this time. however, in january 2012, an entire half-decade after the vehicle rolled off the assembly line, we received a ¿�variable valve timing noise and timing chain noise warranty extension¿� notice by mail from mazda. a month or so after we received the notice, the vehicle began leaking oil. we took our vehicle into a roger beasley mazda center and had it examined. the oil cooler on the vehicle was beginning to fail. we explained the notice that we received in the mail and they were already well aware of these issues. we were told the engine had engine sludge and with it being a second-owner vehicle, we did not have the documentation to prove that regular oil changes had been performed. instead, all repairs and replacements would come from our own pockets. the result ended up being a need to replace the vvt actuator, the timing chain, the oil cooler, and replacing all of the gaskets. the technician showed us a side-by-side of the current timing chain and the new replacement ¿� the used chain had literally stretched to be about half-an-inch longer than the replacement. we drove off the lot and hoped that the problems had been solved. within two months of the repairs, the engine began making a high-pitched whining noise. my wife contacted the dealership that day while at work and they said to bring it in. on the way to the dealership, which is less than ten miles away, the vehicle died on the freeway. this ended up being the result of a blown turbocharger. again, we had to take money from our nest egg to replace yet another part on this vehicle.

my 2007 cx-7 experienced a catastrophic failure of the a/c compressor resulting in smoke in the cabin. after parking to allow the car to clear it would not re-start and i had to be towed to the local dealer. this occurred late on a friday afternoon and so they were closed until the following monday. the potential failure was known and mazda had issued a letter extending the warranty on this item but not a full recall. the dealer installed new parts but since then it has been back several times because of lack of performance. i have received explanations of too much/too little refrigerant block dlines with particles from the original failure. after the third return visit in june 2012 the problem appeared to be fixed and the system worked until last week so i scheduled another visit. the problem has now being diagnosed as a failed hose fitting and they are expecting me to pay for the part but not the labor. my view is that parts like this should not fail at the current 41,000 miles and that some of this is related to the previous fixes. also co-incidentally the check engine light came on as i was scheduling a dealer appointment. this has gone on and off several times over the last month. it has been diagnosed as a failed egr valve and will cost $700 to replace. again this is not something that i would expect to need at such a low mileage and on a car that has all routine serving and has been babied. this prompted me to go on-line to research and there appears to be lots of similar issues with this model of mazda and yet they are not performing recalls. i am hoping that my experience will add to the case to pressurize mazda to be more customer orientated with their cx-7 owners and/or to support a class action suit to help recompense owners against these non routine mechanical failure issues.

the vehicle suddenly stopped running while traveling at 65 mph on interstate 95. the vehicle was safely moved to the side of the road where it was then towed to the dealer where it was purchased. the service representative indicated that the engine would have to be opened at a cost of $500 to determine the cause of the problem. they suspected that the timing chain had broken. after consulting with mazda customer service, i was advised to have the vehicle towed to a mazda dealer. the vehicle was towed to thompson mazda in baltimore, maryland where it was confirmed that the timing chain had broken and that the engine would have to be replaced. mazda had provide an extended warranty on the timing chain for 7 years or 70,000 miles. the warranty indicated that if there was a timing chain noise to bring into a mazda dealer to have it serviced under the warranty. at no time was there a noise experienced from the engine. mazda also indicated that the vehicle had to have service records to be covered. since the vehicle was purchased used in april 2011 we only had our service records and the car fax service records. mazda indicated that because there was a gap in the service records, between 31000 miles (the last record shown by car fax) and 54000 miles (when we had purchased the vehicle), they would not cover the cost of replacing the engine. it is my belief that mazda knew there was a defect in the timing chain and had they been proactive in recalling the vehicle and replacing the timing chain the engine would not have had to be replaced at a more significant cost of $7,200.

on 7/11/12 my wife was driving on the entrance ramp to the fl. turnpike when her mazda cx7, 07 engine turned off completely without warning. she was on a one lane road with a blind sided curve when this happened. a 18 wheeler truck was coming up behind her and almost rear ended her vehicle. fortunately the driver of the truck was able to stop before hitting my wife car. after a investigation of the engine problem i found out that it was a bad timing chain that caused the vehicle to shut off the way it did. i called the mazda manufacture and they told me that they were aware of the timing chain problem and that's why they sent out letters for an extended warranty on the timing chain problem. the also stated that the only way they would replace the part is if i could show records of every oil change that was done on the car from the time of purchase. being that i purchased the vehicle used i am not able to show all the oil change records they request. the point is that the manufacture recognized that there is a problem with the timing chain. they should be doing a immediate recall on the car to fix the problem before somebody gets seriously injured or killed..if you can i ask you to please help with this matter..

driving east across the bay bridge from sf, the engine made a wheezing noise. after a mile the power dropped, and the car would only travel at 30 mph. no engine light came on to warn of this, even during the event. at this point it was obvious that it needed repair attention, and we found a mazda dealer/repair shop relatively close by to drive it to. once they had a chance to diagnose the problem, they reported to us that engine 'sludge' was to blame. the timing chain had been rubbing, and the vvt actuator had been compromised. turbo galleys were also plugged. in jan. of this year, mazda posted an extended warranty for cx-7's timing chain and vvt. however, the dealer informed us after checking with mazda that we were not eligible for the warranty. gaps in our history of repair was the given reason. after an appeal, the rep from mazda said the highest authority had reviewed the claim and again declined to help. we have read numerous complaints from other cx-7 owners with the same problem. many of them have also been denied the use the warranty that mazda has extended.this is a vast and scary problem with this vehicle.

i wanted to report a safety issue with the 2007 mazda cx-7. there is a known problem with the ac compressor and instead of doing a recall on the product they extended the warranty to 5 years or 60,000 miles (instead of 32,000 miles). i bought my car right around the time they sent these letters out, so was unaware of what was going on. recently i was driving the mazda and i smelled smoke. i saw some smoke coming from under the hood, and when i pulled over and opened the hood the ac compressor was on fire. had i not been pulling into work and on the highway i would?ve been in worse shape. it was scary considering it was next to the engine which has oil, fuel, etc...going through it. there were no warning signs that there was a problem with the ac compressor until all of a sudden it caught on fire. i have made attempts to call mazda and try to get some help on this issue, and they seem to not care at all. i wanted to report this in hopes some other owners of the vehicle could be aware and not expect any help from mazda's end. it is a safety issue and it needs to be addressed/recalled.

i started the car, like i regularly do and the engine/timing chain made a horrible sound that got me very worried since this car is taking care very good since its the only car in the household. i contacted mazda and they said the car had a warranty extension for a l3t engine variable valve timing noise and timing chain noise which is cause by " actual failure due to defects in workmanship or materials in accordance with mazda warranty policy and procedures. this warranty extension was for 70,000miles or 7 seven years which ever came first, so my car was not cover since it had 101,000. my concern and disappointment is that after searching and taking to other cx-7 owners the (2007-08) models all had issues with this and mazda did not made a recall just extended the warranty. cars with mileage of as low as 24,000 were affected by it, so its clearly not a wear and tear issue of the car. if that is not replace the engine might be damage and mazda will not even offer a goodwill assistance. i still make monthly payments on the car and its impossible for me to pay $1200 in something that is clearly stated by mazda is a "defect in workmanship or materials". its a shame that so many other customers are still battling with this issue and mazda just hides behind their power and attorneys.

we were driving home on christmas eve going about 65 mph when the cars engine just died. we lost all power to the car including the power steering. thankfully we were on a straight stretch and due to time of night there were not many other cars on the road. we were able to coast to the side of the road safely. the car was towed to a dealership where it was discovered the timing chain broke and damaged the engine in the process. after researching this online i discovered hundreds if not thousands of complaints about a broken timing chain that required replacement of the engine. some of these complaints were as early as 30,000 miles. there was even discussion about a recall on the timing chain from mazda saying that it was defective but mazda was not always honoring this recall. obviously based on these complaints there is a problem with the timing chain in the 2007 cx-7 that needs to be addressed. mazda is not doing anything about it and trying to get out of the mess they created.

i was experiencing a shake in the steering wheel at high speeds, which we attributed to a tire/wheel/alignment issue. i made an appointment when the check engine light came on. the dealership told me i needed the timing chain (and assorted peripherals) replaced...for the second time in two years. the first time was covered by warranty, but only after i produced the records to show the oil had been changed regularly. the second time was not covered under warranty. it cost $1500 to replace the entire assembly that was less than two years old. the dealership has recommended ignoring the manual on oil changes (every 7500 miles) and changing it every 3000 to hopefully catch any further issues. they said because the turbo runs very hot, it burns up the oil quickly. my car was very low when i took it in. they also said the check engine light will not go on due to low oil, but only for low oil pressure. the other issue i had was related to the rear view mirror. i have the auto-dim with compass, which was installed by the dealer when i bought the car. it has failed twice and been replaced under warranty. the second time was around 65k miles. less than a month after my warranty ran out, the entire mirror fell off the windshield. in the early 2007 models, the clip that holds the mirror can not be replaced if it breaks. i had to have the entire windshield replaced in order to re-attach the mirror. i was told even though the mirror would have been covered since it had just been replaced, the windshield was not covered. that was another $250 to replace a perfectly good windshield just because the clip couldn't be fixed. i have seriously considered just trading this car in because i doubt very much it will be worth more than scrap value in a few more years.

EXTERIOR LIGHTING

i was driving down the road at night and headlight on passenger side went out due to condensation see sb-09-003-13 mazda is fully aware of this issue and refuse to do anything about it. i ordered oem parts at a cost of $1400 from mazda and had them installed at certified body shop and within two weeks light blew out again, had to replace just the bulb this time, they said they couldn't cover this cost because a mazda dealer didn't install light. mazda said the only way they would do anything is if there was a safety recall. what does a recall consist of when you are driving down the road at night and both headlights go out at the same time and have an accident or hit someone else head on causing fatalities. this is about as unsafe as anything i can think of. again i reference sb-09-003-13. i hate to know there might be fatalities with this problem and everyone ignores it. i told mazda i would do everything in my power to try and make them responsible for this defect, i guess they have no concern for human life, this is why i am filing this complaint. just think of all the lawsuits that will happen and the monetary cost involved when this does happen and i think it will since it has already happened once, also lose of life, i don't think there is a price to put on this. thank you for your time.

timing chain replaced on 2007 mazda cx7, july 2013. vehicle over extended warranty issued by mazda, repair was out of pocket, even though this is very common problem with this year mazda. now 5 months later, second timing chain has gone bad and mazda is refusing to accept responsibility stating that the new timing chain failure was due to low oil in vehicle. i have service receipts to prove that all oil changes had been done, and that this was not the cause of the second timing chain failing, but more of continuance of faulty, defective mazda parts. this is a huge problem with this company with an outstanding number of consumer complaints. they do not want to accept any responsibility for their own problem, instead putting it all back on the consumer. please, get involved and put a stop to this before these defective parts cause someone to lose their life!!!!

december 2012 (at about 64,000 miles) dealer replaced timing chain under extended warranty but didn't do anything to correct intermittent power loss and engine hesitation that i had complained to them at the time. november 2013 (at about 78,000 miles), the car experienced severe loss of power, stalling and heavy white smoke from the tailpipe. dealer claimed "oil sludge" caused engine and turbo failure and refused to bear any responsibility or cost to fix. mazda usa also refused, claiming the problems were due to insufficient oil change by the customer. since we change oil regularly, we don't buy mazda's claims, especially when they just opened up the engine less than a year ago to change the timing chain, and at that time didn't claim there was any "sludge" inside. seeing many similar customer complaints on the internet, it seems mazda has been trying to hide a serioius design and/or manufacturing flaw by blaming the customers as the cause of it. ?

i purchased a brand new 2007 mazda cx-7 in april 2007, the vehicle started experiencing engine problems in september 2007, i was told it may have something to do with the vvt (variable valve timing) and timing chain. the vvt was replaced by the dealership a short time later; however, not the timing chain. after the vvt was replaced my vehicle starting to experience thick white smoke coming out of the tail pipes. my dealership technician advised this was due to a turbo issue with the engine. all of this occurred within the first couple years of my ownership. i have had the turbo repaired (out of pocket expense), as well as the vvt (2 times) and the timing chain it all seems to no avail. the car is revving very high on cold start ups and is now experiencing a code as of the last couple of days that is stating there is a decarbonization issue with the engine that is linked to the timing chain. of course this is now the 5th time this vehicle engine will be opened up to diagnose one of the known issues that mazda north america is aware of. i have had this vehicle since 2007, and has just over 120,000 miles on it. i have maintained a very good service history on the vehicle taking it to "reliable" mazda dealerships in the area where i live. my main concern is mazda is doing nothing to rectify the issue and it's only a matter of time before someone is seriously hurt or even worse. the vehicle safety is impaired due to unstable engine performance. there is obvious technical issues with the engines for this mazda engine model.

mazda extended the warranty on ac compressors, well, my original compressor failed and was replaced under that original warranty. exactly 30,000 miles later the replacement compressor failed almost 3 years to the date of the original failure. mazda is refusing any responsibility for this since now my car is out of warranty. eventhough the replaced part itself is only 30,000 old. this vehicle is also experiencing timing belt issues and extrememly loud engine noise. this particular model year just seems to be a lemon all around. even the replacement parts are failing. and the company is not holding themselves responsible at all. i've research this particular year and found more than adequate evidence that these vehicles are lemons. the same issues are being reported across the world! and mazda is doing nothing. the hazards they are causing are tremendious! some failures have resulted in fires, quick loss of engine power at high speeds and thousands of dollars in repairs. my car was paid off less than a week before this second compressor malfunctioned. how many cars have had 2 ac compressors in a matter of 6-7 years?? and how many engines can completely fail in the matter of 7 years? everyday when i start my car it sounds like a deisel engine; popping and clanking noises project for the hood like it's a semi. that's just bad craftsmanship and bad business. mazda should be held accountible. the recalls should be extended to 100,000 and 10 years at least. these vehicles should be built to last. and a multi billion dollar company should be made to fix their mistakes before someone gets hurt or worse, killed because of their neglect.

timing chain replacement resulted in a catastrophic failure of the high pressure fuel pump and its housing. replacing the timing chain returned the engine to production line specs, that were too much for a worn fuel pump to handle. the increased pressure to the fuel pump shattered it into numerous pieces less than 100 miles after the timing chain was replaced. said pieces became lodged inside the cam shaft and ended up bending all of the valves. the necessitated a complete valve job, removing and replacing the cylinder head, fuel pump, cam shaft and oil control calve. at worst, all timing chain replacements should require a fuel pump change in order to prevent the sequence of events that happened to my car and thousands of others.

prior to this date, which lead up to the last incident, upon getting the first few oil changes, at a dealership where i purchased the car, the engine began to sound like a truck (oil used was not synthetic and i were scheduled to come back in 5-months). when i inquired about it, i was told, "that was the way it was supposed to sound". after that comment, i changed to another dealership for service. the knocking continued, to this day, still. over the years, the system lights would come on periodically (passenger air bag, check engine light and tire sensor) and the cooling fans would run after you turned the car off. most times, they would reset themselves. moving along, recently on 07/15/14, i was returning home for the evening and the car shut down on me. the steering control was hard but i kept it from crashing the wall on lincoln dr. as i flagged the traffic to proceed, i was able to start the car only to advance to the end of the drive. before i reached home, the car shut down 5-times. finally reaching home it sat until i were able to get it to another dealer, closer to home. how about, the engine is shot, the radiator had a leek, i knew nothing about and the dealer says, "it will not start, now". i drove it to the dealer. oil light was on and smelling as if i burned something, while it knocked. check engine light and passenger air bag light were on when it cut-off, as i pulled into their driveway. i restarted the car found a parking space. once the ignition shutdown, the cooling fans came on. dilemma, i leased the car new in 2007. i bought it, with present car payments until 2016, in 2010. the dealer requests the engine and radiator to be replaced. there is no warranty, especially after 100,000 miles and i have scrap on my hands. where does one go from here as mazda used to be reputable? the engine shouldn't have any problems before 200,000 miles.

after leaving a family member's out of state home early on monday august 25, 2014 morning noticed a noise coming from the front of the vehicle. approximately 5 miles later a burning smell and smoke started coming from the engine compartment along with loud squealing. pulled onto shoulder of road and shut off vehicle. i opened the hood and it was obvious something had burned up but didn't easily identify what. called aaa for a tow to nearest mazda dealer. was informed later in the day by the dealer that the ac compressor had seized up and ruined the serpentine belt as well. they didn't have the parts to fix it which resulted in having to rent a car for 5 days to return home and back to pick up vehicle on saturday. later found out there was an extended warranty on the compressor for 5 yrs/60k miles which meant that there was no coverage on my vehicle since it was 7 years old even though it had only 49k miles on it. total cost with towing, the car rental and repair was $1667. they also "found" the starter was bad and a blown fusible link for which they charged another $648. i think they caused the started and fusible link damage trying to start the vehicle with the seized up ac compressor as i never had any problem with the starter before and didn't attempt to start it after i had pulled over and turned engine off.

i purchased my 2007 mazda cx-7 from a dealership in greensburg, pa in february of 2014, it was purchased as a used car with only 36,500 miles on it. i had no problems with the car at first, then i noticed my gas mileage was getting worse, that is when on memorial day my check engine light would come on and then go off. i took it my mechanic because i was unable to get it in to the dealership for a week at some points and the light would have be off by then. then when i was on my way home on the evening of 9/4/14 my car made a very weird sound any time i would try to push on the gas. i pulled the car off the road and there it sat until i could reach the service department on the following day. my husband took the car to the dealership and that's where it sat because he was informed that it was unsafe to drive? i went up after work only to have them tell me that they could not get the readings from the diagnostic test and that they would have to send it to an actual mazda dealership, where it has been for almost a week. i was informed yesterday that my turbo and other un-mentioned parts had broken. i then waited to hear back as to whether the warranty that i paid an additional $2,000 for at the time of purchase would cover it, it will not cover this and they stated that the turbo was not considered a part of the "powertrain" so they quoted me a price of upwards of $3300 to repair the vehicle that i have had for 7 months. i have started to do research into this vehicle and i have found out that this is actually quite a common problem with this make and model and that the manufacturer will not stand by the product fully knowing that this is a problem and the consumer is left holding quite a hefty bill. i implore you to research this and force their hand so that "joe public" doesn't keep getting stuck holding a huge bill for something this company just doesn't want to fix.
