2008 Infiniti QX56: brake failure

Filed May 5, 2017 · Brakes · 92,000 miles · TX

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).

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.

The brakes on my 2008 infiniti qx56 failed at an intersection today, causing me to go through a stop sign at an intersection. The brake pedal went to the floor and a sporadic grinding noise was heard and felt in the brake pedal. The brake indicator light was illuminated in the instrument cluster. The vehicle coasted to a stop. I pumped the brakes, but had no brake pressure. I put the vehicle in park, then turned it off. When I restarted the vehicle, the brake indicator light was no longer illuminated, and the brakes appeared to be working again. I immediately took the vehicle to my infiniti dealer since this is my primary form of transportation and I have 3 young children. The dealer informed me that the fault code indicated my vehicle had a faulty brake booster, which would need to be replaced for approx. $1000 (parts and labor). They informed me that although they had seen multiple qx56's with this problem come into their dealership, nissan did not have a recall in place. I find this to be unacceptable. I am lucky none of my 3 children were in the car with me at the time, and that no accident resulted from my brake failure.

Multiple incidents (3) of braking issues where vehicle loses braking ability however, it feels as though the ABS brakes are engaging. All three times the vehicle is moving at or about 40 MPH or less and decelerating so I have been able to come to a safe stop. However, I do have to push the brake pedal nearly to the floor and the "brake" warning light also comes on. . When I turn the vehicle off, it resets and I do not have any other issues immediately. The third time (today) 12/12/11, I took the truck to dealer and they, at first, said they were not able to find anything wrong with the vehicle. Then upon further investigation they claim it's a sensor that will cost $1700 to replace. Discussion threads I have read online (from as far back as 2004 until the present) have shown this to be a continuing problem on nissan armada's (the parent company of infiniti) and the qx56's from models 2004 to the present and nissan continues to ignore the problem. Some have even had complete brake failure and accidents. I will take my research to the dealer tomorrow and fight to have my problem taken care of pro bono or I may continue to drive it because I cannot afford $1700 which hopefully will not lead to a worse problem down the road. This needs immediate attention.

2008 infinity qx56 brake failure while driving. On june 30, 2011, while driving the car and turning into a subdivision and trying to apply the breaks, a loud screeching sound was heard and the brakes filed and the brake warning light came on. After pumping the brakes several times they finally worked. This was a day after the car would not in a parking lot because the battery was dead. We had aaa jump start the car and were informed the battery needed to be replaced. Not sure if this is related or not. Took vehicle to dealership and they could not find an issue. The computer did not register the brake light coming on so they had no more information. We found a post on the armada forum club (http://www.clubarmada.com/forums/showthread.php?t=20102&page=3) outlining several people who have had similar issues and nissan still fails to take action on this. My wife was traveling with out 3 children and we are lucky she did not need to stop suddenly when this occurred. Thee dealership is going to do research but something should be done by the manufacturer.
