SERVICE BRAKES, HYDRAULIC:FOUNDATION COMPONENTS:DISC:ROTOR
infiniti qx56 has brake system design flaw. front brakes need replacement on average every 4-6000 miles. brake rotors are too small which causes rotor warpage. as a result, the steering wheel shutters back and forth when brakes are applied. there is no fix for this from nissan. this is brake design flaw also effects similar platforms such as the armada and the titan. there also is a design flaw in the front end which causes the steering wheel to shake violently when going over bumps at speeds in excess of 45 mph. hitting certain bumps in the road can cause the front end to go into resonance, thus shaking the steering wheel enough to loose control of vehicle.*ak

i have complained over the course of 4-6 months about the cruise control going out. it either goes out completely, or the cruise control without smart following goes out. when it does go out, bumping the increase speed button causes the engine to idle thuslosing speed. expecially bad on the interstate. the dealer claims they cannot find the problem (denied this problem 3 times now). seems funny when there is a tsb to cover the work. date here is date of last service to repair paint which is chipping off the front..down to bare metal, and then metal rusting...which is a whole different can of worms.

1. i purchased an infiniti qx56 suv in febuary 2005. in mid march, at 2500 miles, the steering wheel began to shake violently when i tried to stop the car. any time the brakes were applied the shaking would begin.. the entire car would shake every time we hit a bump. from the beginning, it would be very difficult to bring the car to a stop. 2. fortunately we caught the problem before a complete brake failure, as we have 2 young children who are in the car daily. 3. we were told by infiniti that there is a brake defect in the design of the car. according the service technicians at the dealership, the brakes and rotors were not engineered properly and will be problematic every 3000 miles. for now, the dealership replaced the rotors and brakes. *ak

ELECTRICAL SYSTEM
infiniti qx56: intelligent cruise control on vehicle causes all of instrument panel to malfunction and the vehicle to suddenly stop running. this occurs even when the cruise control is not being used. the laser guided system causes electrical malfunctions throughout the vehicle causing gauges to fluctuate randomly and alert lights to give false readings. dealer deems it a "poor design" and considers vehicle unsafe to drive unless the system is replaced. the system is being replaced with the exact same part so the likelihood of recurrence is very high. multiple vehicles affected; dealer had several vehicles in the ship with the exact same problem.

at approximately 8k miles the dealer replaced the rotors and calipers per their service bulletin which seemed to solve the problem. since then, periodically while driving, the brake light will illuminate when brakes are applied and the abs system activates and the brakes begin to groan, are spongy, have less than 10% braking power. this has happened to me 5 times over 90k miles. although i did not make the connection at the time, i believe that it was the cause of a rear end collision that i was involved in 2008 when i attempted to brake the car on the freeway but felt that the car took much too long to come to a complete stop when i quickly slammed on the brakes.the vehicle continues these symptoms until the ignition is turned off. when restarted, the problem is resolved. it has mostly only occurred to me while driving away from a parking spot but yesterday it occurred while i was driving on the freeway at speed exceeding 50 mph. i was only able to stop the vehicle by downshifting my automatic to 1st gear while attempting to activate the emergency brake. i was fortunate that i was on a level freeway and not going down a steep incline. after i was able to safely pull over, the ignition was turned off and the car was restarted with no brake problems. today i took the car into the infiniti dealer and they said that it was a 'common problem' but not a recall and that they would try to reprogram the computer. reprogramming did not work and they said i would need a new abs booster pump at a cost to me of $925. i looked up the problem on consumer websites and found that the problem is fairly common with both the 2004 nissan titan and armada and the infiniti qx56. it seems to be a problem with the c1179 code. what i discovered is that any consumers still had the problem even after they reprogrammed the computer and replaced the abs booster pump. a service bulletin repair exists for the 2004 nissan titan (nhtsa item number: 10020026). this is a serious safety concern.

the airbag warning light comes on. dealer states that it has to do with the seat belt pretensioner wiring. owners manual states that if this light comes on, it most likely means that the airbags are no longer functional. seat belts and airbags are key safety measures. to have them be not functioning is a major concern. if you put in a google search for "air bag light flashing infiniti qx56" you will find hundreds of postings from people with similar problems, so this is not an isolated incident.

periodically, on the order of once every month or two months, the antilock brakes become erratic. the pedal goes soft and the brakes engage extremely violently. when it happened the first time i pulled over to the side of the road and called my infiniti dealer. i kept the engine running while i explained what happened and was told to turn off the engine, wait about ten seconds and then restart the suv. the brakes worked normally after that. i was told the "computer had to be re-booted". this continues to happen on and off about every month or two. never was given a satisfactory explanation as to why this occurs. when it happens if there is no traffic around, i put the car into neutral, turn off the key, then restart the car and the problem resolves. if i am in traffic i slow down gingerly, then pull off to the side of the road and turn off the key and restart the engine. this resolves the problem until the next time.

today, while my wife was driving our 2004 infiniti qx56 with 106,134 miles, she experienced a complete brake failure, along with the "brake" dashboard warning light. it was described to me as the steering wheel and brake pedal shaking, a loud noise from under the vehicle, and the brake pedal going all the way to the floor. this exact same issue is all over the infiniti qx56 / nissan armada forum, the internet, and www.mycarstats.com site to which i'm a subscriber. it's ridiculous that with the number of stated occurrences of this failure on these vehicles that a formal recall has not been mandated to correct this problem. as with most of the other reports of this happening, turning off and restarting the vehicle eliminated the "brake" warning light and the normal pedal feel returned to our vehicle. there is at least one report of this failure resulting in a severe, almost fatal, accident and i'm sure if actually investigated that there are probably more. nissan - infiniti - nhtsa: do something formal about this immediately before someone, their wife, and or children are hurt or killed!

i have a 2004 qx56 and have been having brake problems since i first got it. the brakes were replaced under an initial recall in 2005, but a new problem began in 2006 and has been occurring since. initially, only about once every 2 months, the brakes will sporadically pulsate and the car will come to a quick halt. i would just restart the car and it was fine. the dealership said it was a firmware problem, and "flashed" the firmware. it still kept happening, they flashed the firmware over and over again, and then just said there was nothing more that could be done. now that the truck is out of warranty, the dealership says it is being caused by a bad brake booster, and will cost $1,100 to fix. but this has been happening since long before it was out of warranty, and now it is happening much more often, almost every day. review of different infiniti forums shows many qx56's, nissan armadas, and nissan titans are experiencing this problem. nissan has put out a service bulletin acknowledging the problem, but their solution does not solve the problem. this should really be investigated further and a recall issued for whatever the cause of the problem is.

while traveling on the highway to another state, i attempted to stop my vehicle, an 2004 infiniti qx56, as traffic slowed and stopped. i pressed the brake pedal and heard a clicking sound and the brake indicator light came on and the vehicle would not stop completely. the pedal began to go to the floor then began to feel stiff. i had to swerve to the side of the road to avoid hitting someone else's vehicle. once i completely stopped, i got out and inspected the brake fluid level, and the brakes and both seemed to be fine. i got back in the vehicle and after i turned the ignition on, the brake indicator had went off and the pedal seemed to be working fine. i traveled on to my destination without any other issues. once at my destination, i had the brakes inspected and the repair shop said they could not find an issue. this has happened several more times since this incident, and each time when taken to a repair shop, nothing can be found wrong with my brakes.

stepped on brakes and petal went all the way to floorboard with out stopping the suv. suv finally stopped on speed bump a few feet away. looked in the internet, there are other people with same problem. there is also a couple sueing nissan for this very problem. i think nissan should be held reponsible. the problem i understand is in the brake power booster. it should have being recall.

while driving and starting to apply the brakes there can be heard a grinding sound, brake light displays on the dash and the brake pedal goes to the floor.this is very unsafe to me and the public because once i was able to get home and restart the vehicle it functions like nothing was ever wrong. i drove around the block with no problem stopping which lasted about 2 weeks before it all started again, this time with my family in the vehicle.there are no leaks or squeaking from using my brakes; something needs to be done.
