Infiniti QX56 brake failure problems

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.

My wife was driving her 2008 qx56 and when she tried to brake her foot went to the floor and she heard a grinding noise, she pumped and pumped the brakes but did not notice any measurable slowing down of the vehicle. Fortunately there was no one in front of her and she was evenatually able to safely pull into a parking lot and stop the vehicle. Upon my research this appears to be a know defect. The dealership where I took the car, diagnosed it as a delta stroke sensor defect. Upon researching this there appears to have been a class action suit against nissan/infinitie that the plaintiffs won. If this is a know defect why hasn't there been a recall? My wife could have been seriously injured or killed or she could have injured or killed someone else due to the catastophic loss of brakes. This is not a wear and tear issue and their is no warning that it will happen. You just lose the brakes and the ability to stop. There needs to be a recall before someone dies (if they have not already).

The first time I had issues with my brakes I was fortunate enough to be parked. I turned the vehicle on and tried to releases the emergency brake but the light wouldn't disengage. I put the vehicle in reverse and the applied pressure to the brake but the brakes didn't work. Then the vehicle made a severe grinding noise. I then turned off the vehicle and the problem went away. I then called the dealership and asked if there was a recall for this problem and they said "no". The second time it happened to me I was driving on the road. I notice the brake light turned on, so I slow applied pressed to the brake peddle and the vehicle would stop and began to shake furiously as if it was skidding on the road. Fortunately, their wasn't anyone on the road. The vehicle finally came to a stop and I was lucky enough to pull off the road. I tried pressing the parking brakes to release the light but that didn't work so I tried shutting the vehicle off. I turned the vehicle back on and the light was gone. I slowly began to drive and test the brakes and they work again. I have gone to the dealership and they told me again there was no recall on the issue at hand. The service department said it could be the brake booster but they couldn't find an issue with it so they didn't replace it.

When attempting to stop two times in the past few months the brakes suddenly fail allowing us no ability to stop the car almost causing a serious wreck. The brake pedal goes all the way to the floor with the brake light (not ABS) illuminated on the dash. Even though nissan consumer affairs is aware of this problem they are not being accountable or held responsible for this serious car defect. According to the class action law suit (where there are many others reporting the same problem) the problem is with the active brake booster and vdc control unit. They recommend for me to pay 2-3000 dollars to have the car fixed for a manufacturing defect. Given the severity of this defect in the core brake system across both nissan and infiniti cars and the fact this was taken to court there should be a recall for a failing brake system.

Just purchased a used 2008 qx56 with 118,000 miles. 2 incidents: while coming to a stop, brakes failed and brake light came on. Dealer says low brake fluid so they filled and all seemed fine. 3 days later, coming to a stop traveling less than 30 MPH same thing. The defect continued as I made my way to my house a block away. I can see why this issue would cause an accident and the issue in no way felt like a pin causing an issue with the pedal and bracket as described in recall listed. Vehicle being towed by dealer to determine cause but from reviewing all the complaints here, there seems to be 2 common themes: a brake defect and nissan not figuring it out.
