2004 Infiniti QX56: grinding or squealing brakes

Filed Jun 30, 2018 · Brakes · 74,000 miles · IL

On two separate occasions while the car was moving in a dry parking lot and applying my brakes, my ABS brakes kicked on for no reason and the car was difficult to control and stop. The light came on as well and I heard alot of grinding. This was very scary as both times I had my children in the car. The only way to reset ABS was to turn off vehicle. I am so afraid that this will happen again and I may not be able to stop. I am now afraid to drive and am thinking about selling it because I feel it is not safe to drive.

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 the emergercny brake dash light will become lit and all braking actions have drastically reduced power. A an audible grinding noise is observed from the front of the vehicle and the brake peddle has little to no resistance. A restart of the vehicle temporarily resolve the issue, but the issue has reoccured numerous times and is increasing in frequency.

Emergency brake: e-brake appears to engage on its own and the brake light indicator comes on. There's also a grinding sound when brake is pressed. Grinding sounds only occurs when this issue comes up. Exhaust manifolds: was notified by the dealer upon a service inspection that there was a small crack in the exhaust manifolds. Is this a normal thing? And should this be a recall item as it could throw off any smog check testing. In addition how about the exhaust in the cabin issue? Maybe they used too thin of a metal for the manifolds.

When driving vehicle suddenly makes a loud grinding sound and ABS and brake light come on on gauge. When trying to break it is impossible. It will not stop. This has happened more than 6 times already. Thankfully I was not in traffic or collision and injury could have happened. In order to regain control you have to turn vehicle off to reset it. This problem may cause a severe injury or even death.

I have a 2004 qx56 -- I'm having the same issue with my brakes. All of a sudden the brake light will come on and when you press on the brake you hear a scary loud grinding sound and trying to stop it really tough. It feels like the ABS brakes kicked in --- it has happened several times randomly. As soon as I turned the truck off and restarted it the brake light came off and it started to drive like normal. But I have hit the grass several times bc when this failure occurs you're likely to hit someone in front or, with a sudden grinding stop, someone hit you from behind. I took it to the shop and they said it was a brake issue. So I replaced all 4 brakes and rotors -- yet the problem still happened!! I went back and they said it's probably the delta sensor and it'll be $1000 plus a few hundred to update the computer too. This is very dangerous and the scary part is there is no warning-- it just happens randomly. This is something infiniti / nissan should fix!!

I have a 2004 qx56 and like many of you, I ma having the same issue with my brakes. The brake light will come on and when I press the brake their is a grinding sound and it is very difficult to stop. I turned the truck off and restarted it and the light went out and you couldn't tell that anything was wrong. I took it to the dealer and was told it was my rotors and they "think" the brake booster. This is a very serious problem and nissan needs to be held accountable and made to fix this issue.!

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.
