2006 Infiniti QX56: brake failure

Filed Sep 14, 2022 · Brakes · CA

Brake Failure. The brake fails occasionally while driving on the streets or on the Highways without Waring. The brake pedal goes down to the floor, and grinding/hitting metal to metal sound is heard and vehicle brake control is lost. Experiences were traumatic; you swing left or right to avoid hitting another vehicle from behind or running a red light. The vehicle has been inspected by an independent mechanic, and the brake components: rotors, pads, drum, and fluid levels were ok, each time it occurs. The brake lights come off and on and each time, the mechanic finds no issues with the brake components. One dangerous aspect of these occurrences is that after the vehicle sits for a while, like 30 minutes to one hour, and you go back to driving the vehicle, it appears that the brakes readjust and starts working normally; it continues to work normally about a month, and out of nowhere without warning it fails again and readjusts later. I was about to take my daughter to college out of County, and she has a lot of luggage as she lives in the dormitory; we would not use this Infinity which is a large SUV that could have accommodated me, my daughter and my wife, because of fear of brake failure on the highway. We decided that we would have to use our small compact Lexus instead, but I would not be accommodated in the Lexus because of my daughter's much luggage; my wife and my daughter will make the trip without me. Please look into these break failures.

Multiple times the brakes have went out and I have been unable to stop the vehicle. This has happened in various places and during various circumstances including on the highway and city streets, it has also happened in parking lots. There is no indication, warning lights or signs when they stop working,I find out when I press on the back and it makes a odd sound almost like a spring and a pulsating/grinding feeling when I press the break down. No indicator lights come on when the brakes go out. I am unable to get the vehicle stopped during this time. There has been no set reason or pattern for the breaks going out, they just randomly stop functioning. Normally when this happens for the past year, after I get my vehicle to a complete stop, I turn the vehicle off and then back on and it's back to normal. However the most recent incident was on 2/24/2018 and the brakes went out 4 separate times even with turning the vehicle off. I feared for the safety of my children in the car and myself so the vehicle was returned to my house and not drove again until 2 days later. Infiniti was notified of the problem as well. I am greatly concerned this will end up causing a vehicle accident and injury to my children, myself or anyone else. When this first started happening I had brakes and rotors changed but problem continued. There is no rhyme or reason for when they go out and I have no control over stopping my qx56. This is very concerning to know it can happen at anytime!

Brakes suddenly makes grinding sound when depressed that also sounds like a large spring is about to snap. There is a loss of braking power and the brake pedal gets mushy. This has occurred in heavy stop and go traffic numerous times. If the vehicle is turned off and restarted the problem immediately disappears. The vehicle has new rotors/disc and new pads installed by the dealer. I am in fear for my life because I no longer trust that I will be able to stop when depressing the brakes. I have contacted the dealer and they said I have to bring it in when the problem is occurring.

While traveling on the freeway at about 60 MPH, traffic in front of me began to slow. When I applied the brakes, the break pedal almost went to the floor and made a banging or thumping noise. It felt like the ABS went off and I almost ran into the back of the car in front of me. This has occurred many times since I have owned this vehicle and when I take it to the dealership they cannot find anything wrong and suggest to start replacing parts at the cost of a few thousand dollars. The most recent incident was yesterday while traveling on the freeway. Again I had to stop suddenly as there was debris in the roadway and the brake pedal went to the floor.

We continue to experience intermittent brake failure 2006 infiniti qx 56.we have contacted our local dealership which is infiniti of mission viejo in southern california. Vise does not simply reprogramming the break computer will not be a permanent fix and that we must I replace the brake booster which contains the delta sensor. This will result in an approximate cost of $1000 for us. Our insistence declaring that this is clearly a manufacturer defect should be repaired and replaced free of charge to the in consumer by the manufacturer. The service rep became annoyed and simply told us that you can transfer us to the parts department to get the price on the new brakes. Again this repair is going to cost us nearly $1,000. We will be joining a class action lawsuit that hasn't filed here in california.

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).

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.

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.
