Brake Light On problems of the 2008 Infiniti QX56

Brake light comes on while driving, when pressure is applied to brakes under 40mph there is a grinding noise and the brakes skip. You can turn the ignition off and back on and sometimes the brake light goes off and everything is fine and sometimes it is not. There seems to be no rhyme or reason. Some days it never comes on and some days it never goes off. After researching online it appears that it is an issue with the computer module and a software update is needed. Please fix this. The first time it happened it was very scary! I was driving with my 3 kids and thought that my brakes had went out completely. It was months before it happened again but now it seems to be an every day occurence.

Apparently as all other complaints are similar with the brake light coming on and as I apply pressure to the brake to stop the scrubbing and scraping sound is unbearable, I've been told it's the brake booster is bad for Infiniti Qx56. Fix the problem if everyone is having the same issue, please before someone gets killed. Also there's an exhaust leak which you can tell by a flickering noise when you crank up and accelerate.

During normal operation of the vehicle and while in motion, the abs brake light indicator on the dash control panel illuminates when applying the brakes, which cause the brakes to shake and make scraping sound. At that point the brakes fail to stop the vehicle in a safe distance, increasing the chance of a collision. Abs brake light clears and normal brake functions return when the ignition is turned off, then back on.

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.

Brake light comes on with a grinding sound and brakes fail to hold. Occasionally, slv light illuminates. Some days,it happens very frequently. Rotors and brake pads are new, but the problem still persists.

Vehicle would not stop, and the brake light came on. There was a spring noise coming from the dash. The vehicle was turned off and turned back on and the problem went away. From what I have read on line it is a faulty delta stroke sensor.

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.

The contact owns a 2008 Infiniti Qx56. The contact stated that while driving approximately 10 mph and depressing the brake pedal, she noticed a vibration in the pedal and the vehicle would not stop. The brake light, vdc and the abs warning lights illuminated on the instrument panel. The failure recurred six times while the contact was traveling at different speeds. The vehicle was taken to the dealer six different times. The technician stated the brake booster and the master vac assembly would have to be replaced. The vehicle was repaired however, the failure recurred and resulted in the contact being involved in a crash. The vehicle was not further repaired. The approximate failure mileage was 48,670.

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. . Read more...

Last week I experienced two separate, unrelated safety problems with my 2008 Infiniti Qx56. On Thursday the truck abruptly lost all power including power steering and brakes and came to rest on a highway. It turns out that I had run out of fuel, despite the fuel gauge reading just under half a tank remaining. I had earlier been notified of a recall regarding this issue, but was on a wait list due to lack of replacement parts. The vehicle was repaired per the recall the next day, Friday. On Sunday, the vehicle suddenly lost it's brakes, the brake pedal fell to the floor, and the brake warning light went off. I was able to bring the vehicle to stop and had it towed to the dealer, who confirmed the failure and attributed it to a failed master brake booster.
