Since I purchased my qx56 2006, it has happen several times, I think approximately 40 times, I got scared at the beginning and freaked out, all my family was with me and we didn't know what to do, all I did was turn the car off and wait for a minute then I did turn the car on and the problem was gone, I'm not the only person that has this happen and hope that you guys do something about it the only big problem I think is that I'm afraid that if this happen again and I will not be able to stop my car and will cause death by hitting somebody, I had a small incident but there was no big damage and the car in front of me heard the noise but we didn't fill a report if you have any questions, you have my VIN # and you can find me I hope that nissan does something about this.
2006 Infiniti QX56 brakes complaints
Page 3 of 3: complaints 41 to 58 of 58, newest first, as owners wrote them.
I was driving with my family in the car and exiting off the highway. When tried to stop for approaching traffic my brake warning like came on the brake pedal became unresponsive. As I pressed the brakes I could hear a broken spring kind of sound and it felt like the ABS system was trying to kick on. The car did slow but the brakes were at about 20%. To avoid hitting the approaching cars I had to swerve off the road. We were able to get the car to a stop but clearly would hit the cars in front of me if I were not able to get off the road. While we did not have a crash I did notice two large scrapes on the right side of the car from rubbing against the rail which I did not notice till late the day after. After turning off the car the brakes worked like nothing ever happened. We took the to a local dealership the next morning and we told that "yea that has been happening" with that model. When I searched the internet for the error code I was given (c1179) I found almost 200 hundred people with a similar story to mine. My vehicle has been dealer serviced with every recommenced service. While I understand that cars are machines and they do fail, brakes failing like this due to a bad sensor is a death waiting to happen. As a loyal nissan/inifiniti customer I am very disappointed that this well document issue has not been proactively addressed. For those reading this at the federal safety agency please understand that someone will die due to issue. Review the 16 claims on your site today, it is just a matter of time. Lawyers wont touch this unless you have a severe personal injury and nissan wont act till lawyers take suit...you do the unfortunate math. Nissan/inifiniti - I just expect more.
Tl* the contact owns a 2006 infinity qx56. The contact stated that the brake lights illuminated while driving at approximately 30 MPH. In addition, the brakes would exhibit an abnormal grinding. The vehicle was powered off and when restarted, resumed normal operation. The vehicle was taken to the dealer for further inspection. The manufacturer was not made aware of the failure. The failure and current mileage was 128,000.
Multiple/numerous incidents: while at both high speeds (highway) and local driving the dashboard flicker and the ABS light comes on followed by loss of braking, groaning/grinding noise and inability to control the vehicle speed. This has occurred numerous (>20) times and the only resolution is to pull over, stop the vehicle and then restart the ignition to reset the braking system. In addition, we have lost brakes twice that resulted in the vehicle travelling through a red light at a 4 way intersection. There is an infiniti technical service bulletin related to the issue (itb-06-011 and itb-10-074) however the dealer has been unable to resolve the issue following these procedures. A complaint was filed with infiniti consumer affairs (case[xxx]) however after reviewing they have refused to provide any further assistance in the matter. Information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).
Was traveling at approx 40mph in dry conditions on a good road surface and approaching traffic lights at an intersection. Applied the foot brake lightly and immediately noticed the brake pedal travel was significantly increased. Groaning & grinding noises emanated from front end and could be felt through the brake pedal. It was as if the ABS had engaged even though the car was braking gently on a good, dry road surface. Glancing at the dashboard I noticed the brake light was illuminated. Running out of stopping distance, I tried pumping the brakes and noticed a "rapid popping" noise as the brake pedal was traveling back up. Brake efficiency was significantly reduced but the vehicle did come to a stop albeit in an uncontrolled and dangerous manner. After traffic lights changed, I pulled over the intersection to stop on the side of road and the same problem re-occurred. The problem vanished after switching off the engine and despite trying for several hours the following day on an empty road; I could not reproduce the problem. Infiniti dealer investigated but found no dtc code and stated a known software problem was not the cause (version was already up-to-date). Dealer was unable to reproduce the problem. Following that first incident, the problem randomly re-occurred approximately 1 time every 3 months - each time a stop / restart of the engine would resolve the problem. Testing brake function during subsequent occurrences of the problem revealed that emergency brake function was seriously degraded and overall stopping distance increased by more than double. In the last several months the frequency of the problem has increased to the point it now occurs several times a week. The problem appears more frequently during the hot / summer months.
Pulling out of neighborhood on busy highway 34 MPH. Brake failure, loud grinding and brake light came on. Able to avoid oncoming traffic by pulling onto side of road. Turn car off and back on and has breaks back but very scared.
Tl* the contact owns a 2006 infiniti qx56. The contact stated that while driving at various speeds or starting the vehicle, the brake warning light illuminated and there was a grinding sound. The contact was unable to brake and had to depress the break pedal all the way to the floor board. The vehicle would pull and jerk before finally stopping. The contact stated in order to resolve the failure he would change the gear to park, turn the vehicle off and restart the vehicle. The vehicle was taken to the dealer however dealer was unable to provide diagnostic because failure is not present at moment. The failure occurs randomly and consistently. The current mileage was 151,000. The failure mileage was 26,000.
Brake light came on and slip light as well car couldn't break at all . Than one day to another the problem went away , than came back then back to normal. Now I have like 2 month with the lights on and I still have the problem with another problem with the drive shift some time get stuck I can not put the car in ( p ) park or ( d ) drive I see there have been alot of complaints about this situation , don't know if is a recall for it . Remember this car make some noise before brake but I checked brake pads and rotor everything was good. Hope you understand my situation . Thanks.
While driving, and without warning, ABS brake light comes on and brakes have severe vibrations and do not stop vehicle normally. Problem goes away with restart but comes back periodically( 2-3 times per month). Dealership is aware of problem but refuses to address it because it is too expensive to fix. Cost estimate is $2000. This problem is documented on numerous websites and is likely to result in death if not addressed. Very dangerous situation, notified infiniti who refused to fix problem because I had not done all my scheduled services at the dealership - in other words, because I wasn't a good enough customer they were unwilling to repair dangerous braking issue.
Tl* the contact owns a 2006 infiniti qx56. The contact was driving 55 MPH when the brakes failed and the contact was unable to stop the vehicle. The contact had to travel down a dirt road and coast to a stop. The failure was experienced several times. The vehicle was taken to the dealer who performed a diagnostic that located the failure at the brake booster sensor. The dealer replaced the brake booster sensor, but the failure was not corrected. The manufacturer advised the contact that the brake failure was not recalled and they could not guarantee that the failure would be permanently corrected if the brake booster sensor was replaced for a second time. The vehicle was not further repaired. The failure mileage was 41,431 and the current mileage was 53,459.
I have a 2006 infiniti qx56 with 46,000 mile on it, and my brakes failed on me approximately 4 times already, but just coming out of a drive way or backing up from a parking lot, I would have to turn off the truck and turn it back on for the brakes to function normal again. When it failed and I pressed on the brake I noticed the brake light on the dash would turn on and I would hear grinding noise from the brakes and it seems as the pads are barley grabbing the rotors. It been a scary experience for me and my family. It my family truck and I have a wife and 4 kids. I was also told it could be the brake booster and it needs to be replaced, there should be a recall on these for the nissan armadas and infiniti qx56.
Serious brake failure on a 2006 infinity qx56. The brake light randomly come on and then the brake system essentially fails, with loud mechanical sounds, shuttering of the truck, and essentially an inability to stop the truck. There is no way to predict its occurrence and this is a potentially deadly situation.
Applied pressure on the brakes and brakes start to grab and makes a grinding noise. After this occurs the brake light comes on and I have a continuous grabbing as if the brakes are about to lock. I have taken my car to the dealer twice already the first time the service department reprogrammed the computer system. The second time they could not find anything wrong I am still having this problem and will be returning my vehicle back for a third time.
In the past six months I have had two brake failures. The most recent was 01/23/2011. While in motion at a speed of approximately 25 MPH I applied the brakes but rather than working, the pedal went to the floor with no resistance whatsoever. I lost all braking control and coasted right through a stop sign nearly being broadsided by a semi truck. June, 2010: while leaving my neighborhood going downhill I applied my brakes as usual and to my surprise the brakes went to the floor making a loud ratcheting or spring noise with no braking effect whatsoever. After rolling to a stop I returned home and parked the car. Believing I needed new brakes or brake fluid, I immediately made an appointment for the next morning. The next morning I had intended to call aaa for a tow but discovered the brakes worked perfectly fine. I therefore drove the vehicle to the repair shop. They performed a thorough examination of the brake system but found nothing wrong and the brake system seemed to work well so no further action seemed to be needed. 01/23/2011: when driving at a slow speed I approached a stop sign before entering a highway and as I applied the brakes they made the same sound similar to a recoiling spring as I depressed the pedal. There was no resistance and depressing the pedal had no effect whatsoever. I cruised through the stop nearly being hit by an oncoming truck. To stop my vehicle I downshifted to third, second and first and cruised to a stop. After a few seconds of composure, I turned the vehicle off, waited approximately 30 seconds and restarted the engine. As soon as I did the brakes worked just fine with no continuing problem. This appears to be a computer problem, is very serious, and deems the vehicle as unsafe and unusable until the problem is definitively found and resolved.
Tl*the contact owns a 2006 infiniti qx56. While driving approximately 30 MPH, the contact applied pressure to the brakes when she heard a loud grinding noise followed by excessive shaking of the steering wheel. The contact also noticed that the emergency brake warning light illuminated but the brake was not actually on. The contact powered the vehicle off, turned it on again and the emergency brake light shut off. The dealer was notified and performed a diagnostic test, which confirmed that the delta sensor in the booster assembly needed to be replaced. The vehicle was repaired. The manufacturer was informed and the contact was waiting for a response. The current mileage was approximately 108,000. The failure mileage was approximately 107,900.
Brakes shutter and stop working on 2006 infiniti qx56. Determined that the ABS needed a firmware update. Went to dealership, paid $100.00 for update and problem is still occurring. This is my wife's vehicle and she travels with my 2 year old daughter. There are hundreds if not thousands of similar complaints on nissan user forum boards.
My wife was driving our SUV when a car cut in front of her and she slammed on her brake to avoid hitting the car that had cut her off. Her foot on the pedal went all the way to the floor and her brake light flashed repeatedly. She had no brake and put the car in neutral to allow the car to come to a stop. We had the car towed to the dealership. Initially we were told that the power booster/master cylinder and possibly a vdc problem that needs to be replaced. I was called later on that day and was told that infiniti had issued a bulletin which only calls for vdc unit to be re-set. I feared safety for my wife and two children and contacted infiniti consumer hotline and they basically told me that they will not replace the unit and "if the unit fails again, then they will consider other options".
Brake failure on 2006 infiniti qx56. One time. Situation dangerous, driver avoiding pedestrians and vehicles on a busy thoroughfare.
