2004 Infiniti QX56: brake failure

Filed Nov 6, 2016 · Brakes · 93,313 miles · CA

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.

While driving and starting to apply the brakes there can be heard a grinding sound, brake light displays on the dash and the brake pedal goes to the floor.this is very unsafe to me and the public because once I was able to get home and restart the vehicle it functions like nothing was ever wrong. I drove around the block with no problem stopping which lasted about 2 weeks before it all started again, this time with my family in the vehicle.there are no leaks or squeaking from using my brakes; something needs to be done.

Same issue as all other posting..loss of brakes, shudder, lights go off. I had it towed in. As it was under warranty, they reprogrammed and redid all brakes...now, same problem 9 months ago..I cleared everything and it recurred again..this is lifethreatening...I'm amazed no action has been taken with all these posts (and many others on other compliant boards). Will someone have to get killed and then officially start a class-action?

Brake pedal doing all the down to the floor. After turning the vehicle off and restart, everything turn back to the normal and warning light gone. This is serious issue and manufacturer should fix the problem before any body die.

Today, while my wife was driving our 2004 infiniti qx56 with 106,134 miles, she experienced a complete brake failure, along with the "brake" dashboard warning light. It was described to me as the steering wheel and brake pedal shaking, a loud noise from under the vehicle, and the brake pedal going all the way to the floor. This exact same issue is all over the infiniti qx56 / nissan armada forum, the internet, and www.mycarstats.com site to which I'm a subscriber. It's ridiculous that with the number of stated occurrences of this failure on these vehicles that a formal recall has not been mandated to correct this problem. As with most of the other reports of this happening, turning off and restarting the vehicle eliminated the "brake" warning light and the normal pedal feel returned to our vehicle. There is at least one report of this failure resulting in a severe, almost fatal, accident and I'm sure if actually investigated that there are probably more. Nissan - infiniti - the federal safety agency: do something formal about this immediately before someone, their wife, and or children are hurt or killed!

Tla* the contact owns 2004 infinity quiz. While driving at approximately 30 MPH, when the brake pedal was applied it went down to the floor, made a loud noise and failed to operate. The ABS brake light illuminated after the failure occurred. The contact shifted the gear from fourth gear to first gear to slow the vehicle down. The manufacturer took a report and advised the contact to take the vehicle to the dealer to be diagnosed, because there was not a recall or a technical service bulletin for the brake failure. The failure mileage was 89,000 and the current mileage was 99,008. Updated 10/22/10 *bf the consumer stated there is a failure in the sensor inside the brake booster. Updated 10/26/10

I have had my vehicle in for repair a total of 6 times for the brakes. 6/05 and 9/05 for a shudder and squeak issue. 4/06, 8/06, 9/06 and 11/06 for a complete brake failure issue. The dealer does not seem to be able to fix the problem and it is a safety hazard to drive the vehicle. There is no warning when the brakes fail.

1. I purchased an infiniti qx56 SUV in febuary 2005. In mid march, at 2500 miles, the steering wheel began to shake violently when I tried to stop the car. Any time the brakes were applied the shaking would begin.. The entire car would shake every time we hit a bump. From the beginning, it would be very difficult to bring the car to a stop. 2. Fortunately we caught the problem before a complete brake failure, as we have 2 young children who are in the car daily. 3. We were told by infiniti that there is a brake defect in the design of the car. According the service technicians at the dealership, the brakes and rotors were not engineered properly and will be problematic every 3000 miles. For now, the dealership replaced the rotors and brakes.

I leased a new infiniti qx56. The brakes failed at 2500 miles and pads and rotors had to be replaced. My car is being serviced again today for the same reason. The steering wheel shakes uncontrollable when the brakes and rotors wear. I have been driving for over 20 years and have never had brakes fail every 2500 miles!
