VISIBILITY:WINDSHIELD WIPER/WASHER:MOTOR

i own a 2007 hummer h3. driving home in a snowstorm last night, the wipers stopped working. i called the dealer and had the car towed to the dealership. they tell me that since the area around the wiper blades is so large, this should be expected and that they had several other calls on the same issue. i was in a snow storm and could have been in a severe accident. this is a safety issue that needs to be addressed. i bought the h3 to drive in the winter, however i do not feel that it is safe to drive in snow. need help from gm on this one. *nm

SEATS:FRONT ASSEMBLY:SEAT HEATER/COOLER

yesterday mavis was visiting our daughter (brenda) in killeen. brenda owns one of those fancy h3 burnt orange hummers with all the doodads. it looks like it just rolled off of fort hood ready for warfare. if fact it attacked my lovely demure wife with no provocation whatsoever. now realize i was dutifully working at my job while mavis was out but she swears by the story and at me. mavis and brenda jump in the hummer to go see the doctor in temple which is about a 20 mile trip. brenda was driving. shortly after leaving the house mavis starts squirming around in the seat complaining about how hot the seat was and trying to figure out how to turn the darn seat heater off. she thought maybe she was having hot flashes. brenda pulls off the side of the highway and runs around the hummer, hoping no one runs over them, to turn off the seat heater. she turns the heater off or so she thought. she heads down the road again when mavis hollers that her bottom was burning off. she pulls off the road again and they finally get the darn thing turned off. the seat and mavis? bottom start to cool down. after visiting the family doctor they returned to killeen and mavis jumped in our car to head for home. the 2 hour trip from killeen to red oak took nearly 6 hours. some knot head damaged a bridge on i35 shutting down the highway. i was watching tv when mavis got home and she immediately runs in the bedroom pulling down her slacks and she shows me 1st and 2nd degree burns on the back of her thighs and her bottom. the burns look very painful and very ugly. i took pictures. some pictures are of the burns. today brenda called gm to inform them of the attack. they think a heat sensor must have failed but we?ll know more after they take a look at it. it?s amazing that neither the seat nor her clothing showed any heat damage. mavis is doing well but is a bit tender. she is going to be sore for a few days. *jb

my wife was driving the posted speed limit of 45 mph, when another driver turned from a cross street into her, causing a head on collision. full frontal damage to both vehicles occurred, and the airbag in our vehicle did not deploy. the airbag in the other vehicle did deploy. onstar was notified of the accident as well as local law enforcement. the other driver was designated as the at- fault driver in the accident. i did contact gm and notified them of the failure of the airbag to deploy, and their legal department claims that if the "crumple zones" did their jobs then the airbag would not deploy, even in a head on collision. our vehicle is still at the tow lot, and the airbag is still intact.

VISIBILITY

this is the first winter this vehicle has seen. on three separate occasions the windshield wipers have either not worked or stopped midcycle. the first incident was at home. i have autostart so i started my card to warm the vehicle and thaw the windshield. approx. two hours later i was able to turn on my wipers. the same thing happened on a second occasion. on december 31,2008 during a storm that caused white out conditions, my wipers stopped less than 5 minutes into my drive home. the design of the wipers causes the arm that moves the wiper itself to freeze solid and cannot be unfrozen until you get the vehicle into a warm environment, unless you're fortunate enough to have an ice pick or boiling water with you! the vehicle has a serious design problem with the wipers and needs to be addressed before someone is seriously injured or killed.

STEERING

on november 2, 2008 at approximately 9:30 pm, i was pulling into a parking space at the local wal-mart and as i turned right to get into the space i heard a loud bang proceeded with my hummer h3 abruptly stopping. i didn't know what had actually happened at that exact time as i was more concerned with the safety of my 11 yr old brother. i called on star emergency services and told them i could not move my car and was not fully aware of what had happened. the wal-mart security guard that witnessed the entire incident, rushed to the vehicle to check if we were alright and asked if i had realized what had happened to my car. i told him no and with the on star rep still on the phone i got down and to my surprise saw the steering column of my hummer had snapped in half. i was in total disbelief and couldn't help but think how my brother and i could have flipped over on the freeway if this incident would have happened one the way to wal-mart. after describing to on star what had happened, the representative asked if i could move my car or if it was drivable, i told him i was pretty much stuck where i was and couldn't even move out of the way of the traffic. i waited along with the security guard for a tow truck to arrive and was the tow truck got there i wrote down all the information i needed from the security guard and was told by the tow truck driver that my vehicle would not be taken to the dealership until the following morning. the next morning i went to the dealership, and was told that i had to contact gm because my brother had been hurt at the scene. i contacted gm and was told that they would send an independent inspector to take a look at the vehicle. after waiting for almost 3 weeks i was told by the gm rep, jorge aburto that the report stated that no outside factor to have caused what had happened to the vehicle. once gm gave the ok to start the repair on the h3 i was told they had stopped because the dealership is now accusing me of hitting the h3.

i was in an accident 3/22/2009, 2007 hummer h3, the other driver lost control and his explorer traveled horizontally on freeway 5, in los angeles. i t boned him i was traveling 65 mph at time of impact. the hummer was totaled the front end damaged fatally. my airbags did not deploy. i suffered and still suffer from a back injury i have had 5 procedures to my back for pain and numbness. i was the driver. my husband was a passenger and he required knee surgery due to an injury caused by hitting the dash. he and i both still have daily pain and my ability to perform my job has been compromised. i cannot take narcotic pain medications secondary to my job, so i suffer daily. i have photos of the both vehicles involved. i think if the airbags would have deployed i and my husband may not have had such damaging and long term injuries. i have researched that the 2006 hummer air bags ( cloth seats) had issues. my vehicle had cloth seats.this may not be the appropriate forum but i had a paid service onstar. the onstar service failed to respond after the accident. i called them on my cell phone and they stated they would call the chp. eventually the onstar called me on my vehicle but the tow truck and chp had already arrived. . my husband called 911 immediately after the accident.

i was driving off-road in my 2007 hummer h3 with a group of hummer owners. driving on a flat dirt road, approaching the paved road, the side impact air bags deployed for no reason. h3 was going aprox. 35 mph. i had my son with me in the front seat and he was hurt by the airbag. i've seen other reports of this happening with h3's and the issue should be corrected by gm. either the sensor is defective or is set too sensitive for off-road driving. i'm thankful it didn't happen on a busy freeway or on a busy street. my h3 has been in at the gm dealer for 7 days and they are wanting my insurance to pay for the repairs. that means deductibles and rental car fees for me to fix an issue that should be corrected by gm.

ever since i purchased this vehicle, the vehicle has stalled at between 25mph and 0. i work for the us census bureau, permanent worker and i travel through all types of weather conditions in a day, from 9,000 ft mountains covered in snow to desert gravel roads, mesas, cliffs. over the past two years the vehicle has shut off while traversing mountain roads covered in snow with no guard rails, and three times, when the engine shut off, i lost steering and came within inches of going off the side (cliffs) of these roads, not to mention in town, when my engine shuts off as i drive, i have come close to hitting other vehicles or poles as i lose power steering on a turn.. i have to drive about 90 miles one way to get it serviced, while under warranty, i had it "repaired" about five times, no success, once warranty expired, gm dealers 90 miles away were still willing to inspect vehicle since problems started while under full gm warranty, but now, they refuse to give me a rental and tell me they do not know what the problem is. my local gm dealer (alamogordo) refuses to inspect vehicle and thus i am required to make a 180 mile round trip, but now, even dealer tells me they do not know what the issue is and they cannot reproduce the problem in the shop. i took about 6 videos with my droid after the problem happens, because the problem lingers for about 15 minutes, then it stops and the vehicle works fine. the videos how the rpm's going up and down, up and down, until the car shuts off, i restart it, then it shuts off again, over and over again. problems usually appear in the am, as i drive off for the first time, before it is driven a good distance, but can and has happened at any moment. very dangerous and i do not feel safe each morning as i leave my mountain home, especially in cold snow weather.

i am the original owner of a 2007 general motors hummer h3. the auto has been well maintained and professionally serviced by a gm dealership. the vehicle has 53,600 miles and is in perfect mechanical condition except this recent issue with passlock security which has rendered the vehicle unreliable and a personal and public safety hazard. the vehicle is less than 30 days out of warranty and dealer will not repair under warranty. in recent weeks, the passlock security light began randomly illuminating while driving. this light could extinguish on next start or stay illuminated through several starts. two weeks ago while returning from a trip later at night, the vehicle was disabled and failed to start in an airport parking lot. the passlock light continually flashed and the engine cranked, but without starting. a tow truck was called, but by the time it arrived, an attempt to start the vehicle was successful and the light was extinguished. this has happened at least twice since in less inconvenient and less dangerous areas. the vehicle is unreliable and unsafe. i cannot trust it to allow my wife to drive it for fear if her being marooned in a dangerous situation. the dealer has indicated it might be several hundred dollars to repair this problem and was well aware that it was a widespread problem with gm autos. there are hundreds of similar complaints on the internet and yet there is no response or attempt to remedy this situation by the manufacturer. i am a senior citizen and need to rely on my vehicle, but cannot rely on a vehicle whose security system can disable the vehicle at any random time. as my representative, i request the nhtsa address this with the manufacturer and remedy this safety concern.

i was in a parking lot, i started the vehicle and turned the air conditioner on. it worked but suddenly stopped blowing air. i took it in and it was diagnosed as the blower motor resistor had gone out. i had it replaced only to have the same thing happen again one week later but this time i smelled something burning. the wiring had burned going to the resistor. the technician informed me that this happens often with these vehicles and he doesn't understand why there isn't a recall. after researching the problem, i found that this is a common and potentially very dangerous problem with the hummer h3. there needs to be an investigation and recall so that no one gets hurt. if i had a passenger in my vehicle at the time of this incident, they would have received burns on their feet from the wiring malfunction and burning. i again am having to pay to get this corrected. vin # [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

this vehicle has had transmission issues since 25,000 miles. no code ever indicated so dealers would not investigate transmission until 1st and 2nd gears failed. problem of incorrect shifting continued with several stops at the dealership. no code no service. now the transmission slammed in reverse initiating a code (speed sensor pass/fail). after agreeing to replace the portion of the transmission that contains the shorted speed sensor, it was discovered the transmission was contaminated by radiator fluid. now the radiator, not covered by warranty, also must be replaced with the complete transmission. researching hummer forums, this is apparently a known issue with the speed sensor and radiator contamination that is being ignored.

the anti-theft passlock system is faulty and will not let me start my car. it has happened twice since i got the car in december of last year. going on-line to see what to do about it made me aware of the overwhelming amount of gm car owners that this has affected. some being stranded for hours and days of not being able to start their cars due to the faulty passlock system. it is happening to all makes and models of gm cars. i called gm and they weren't interested in doing anything about the problem unless you force them to. please check into this and help those of us who get stranded in places (sometimes scary places) because our car won't start. thank you.

had purchased vehicle 3 days prior from individual. drove to el paso tx1 approximately 80 miles drove around town doing errands. transmission started slipping badly, i pulled into a wal-mart and went to check the transmission fluid. vehicle had a compression type dipstick. when i touched the lever on the dipstick it shot up approximately 8 inches and showered my right hand with very hot transmission fluid. this caused second degree burns to the palm and fingers, this made a trip to the emergency room necessary. the owner of the transmission shop told me that in his 20 years in the business he had never seen a transmission get so hot as to melt the filter. this one had melted the filter.

ENGINE AND ENGINE COOLING

i was driving on the express way when i noticed my engine rev real high. i looked at the rpm's and it was almost red lined. i let off the gas imediatly and came to a slow crawl and found that it would not shift out of second gear. pulled it off the road and shut it off to get out to find that there was transmission fluid and radiator coolant pouring from the transmission. had it towed to a mechanic to find out that the radiator was bad which caused the transmission and coolant to mix between the two. this causing the transmission to be destroyed along with the radiator. for this vehical being this low on miles this should have never happend. gm has made a faulty radiator and something needs to be done.

FUEL SYSTEM, GASOLINE

smelled radiator fluent when i parked into the drive way, popped the hood and saw that the liquid splashed all over the engine and parts as well as on top of the plastic fan cover, which seemed odd. couldn't find the leak in the hose. looked at the hummer forum that i'm a member of and lord behold there was a big topic of radiators cracking and breaking in the same places with the 2007 models. no recall has been issued, so no recall has been submitted. but it's a well known defective radiator problem that gm knows about but won't recall. so they decided to make a new radiator that fixes the problem for the 2007 hummers. the problem is the middle pin that holds the radiator rubs the neck and starts a cracked under the styrofoam, thus the right drivers side cracks in the same spot as well on the plastic side. hundreds of h3 owners had this happen to them and post pics and what not, but still no recall. this problem is ongoing and nothing is being done. i have spoke to the hummer customer service and they contacted the local gm and they scheduled my scheduled date to take my h3 in feb 17 2014, @ 8 am at the local gm dealership and hopefully they will fix this issue and not charged me to fix due to the fact that they know the problem and have done nothing to fix it. but it's been know that they will not fix the radiator and they say it's due to climate which is false because every h3 owner has it break in the same place, and have submitted countless tickets.

ENGINE AND ENGINE COOLING

i was sitting in the line at my son's school, been sitting there 2 - 3 minutes, and i smelled coolant. looked at my gauge and it was riding just below mid-point....normal. got my son and started home. sitting at the red light, i smelled coolant again. this time i knew it was my car. we went to a service station and ask if someone could check to see if we had a leak. they pulled my h3 into the back and hooked up a pressure "tool" to the radiator and low and behold, but a hairline crack on the upper driver's side of the radiator. the mechanic laughed and said i was the 2nd one this week and the 6th one since they opened 6 months ago. he said that h3s were known to have radiator issues because the radiators were plastic! seriously...plastic! i was given a quote of $1,100 to replace the radiator with another plastic one and that would give me a 2 year or 24,000 mile warranty. i brought the truck back to my house so my husband could look at it. i did some research on the internet and it seems that this is a well known problem with hummers and yet gm has not done a recall. i found a number for hummer customer service and called them. when i told the man that answered i had coolant leaking, he said "oh, give me your zip code and i will find a local dealership that can replace the radiator." no questions...he knew what the problem was already. he went on to say that we would have to "invest" in a diagnostic and if the dealership determined it was a manufacturers defect, that hummer might "participate" in the repair costs. i would think with this being such a common problem, a recall would be in order and possibly a replacement radiator that isn't plastic!

my car began show the passlock disabling system light and then failing to start. after starting, it would then show the air bag warning lights for a period that might be several minutes to several days before going out again. this cycle happened at random times disabling the auto without warning and in some dangerous situations. it is a well known and publicized problem that gm has chosen to ignore. i have solved the problem by having passlock disabled and ignoring the air bag warning light with the assumption it is a false warning. these recent events have me reconsidering that action, but the cost of having the problem rectified would be more than i could afford.

i own a 2007 hummer h3 with 66000 miles on it. it has been diagnosed as having a bad head due to the use of soft metals for the cylinder sleeve. due to this, there is sudden reduced power. the cost of this fix is about $4500.00. my truck began with a check engine light on (autozone) said it was a misfire on cylinder #5. i went to the local dealer and asked them to look at the truck. they diagnosed it as a #5 cylinder having the compression leak of 90%. in looking on the internet (at hummer forums), i observed that quite a few hummer h3 owners were writing in about their experience with misfires and bad heads, at about the same mileage. i think this needs to be looked into and that gm should be ordered to do a recall. this is the same problem they had with the 3.5l engines they used in their pre-2007 hummer h3 and colorado. i am going to write my congress rep and ask that with the problems that gm is having right now, that this also be moved forward and that they order an investigation. any other hummer h3 owners with the same problems should do the same thing.

i purchased this vehicle, new in july 2007. since that time i have meticulously maintained the vehicle. on 7/28/14, parked at home. got out and smelled coolant vaporizing (distinct smell). i am a retired master mechanic, with 44 years experience (currently age 60). i examined the radiator, rinsed it off and dried it, pressurized the system to discover a hairline crack in the upper, plastic tank of the radiator in an area with no impingement of other components, no trauma, and no rough use, ever. i caught it at the very first manifestation, solely by the smell. examining the vehicle closely to discover while my radiator had only this hairline crack in a location of no-stress and no impingement of other components. research further to discover this is a very common problem with the h3, from 2006, 2007, 2008 and 2009 models all in the 50,000 to 100,000 mile readings. the replacement of the radiator at local gm dealer, with cooling system service was extremely expensive as the replacement of the radiator requires the receiver dryer of the air conditioning system to be disconnected which requires discharge and recharge of refrigerant r124a. i saved the defective radiator. there is no other wear nor damage. the internal cores were clear and clean like new. no obstructions, dirt nor wear. in other words i was forced to replace a perfectly good radiator for 1 hairline crack on the upper plastic tank. this repair, including all courtesy discounts from the selling dealership, as i had been an auto repair shop owner and loyal customer for 30 years of my life, cost me $966.57. nhtsa should do a formal defect investigation on all the hummer h3 models and any / all other gm like-type vehicles with the plastic tank radiators which could cause a serious accident or death.
