2004 Infiniti QX56: ABS light or ABS activating

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.

While driving at low/high speeds, the brake light will just turn on unexpectedly. Also, the ABS brakes seem to fail where you have to press the brake pedal to the floor. The only way to temporarily fix this is to turn the engine off and turn it back on for the brake light to go away. Again, this will occur at least 1-2 times a day and/or 28 times in a month while driving. This is a very dangerous situation to put a driver in on the highway or other roadways.

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!!

While I'm driving, the brake light on my cluster would come on and if I try to brake, the pedal would just go to the floor and the vehicle would feel as if ABS is kicking in. This is very dangerous as I've ran through multiple red lights and pedestrian crosswalks due to the brakes not working properly. Thank god I haven't hurt anyone or myself due to this on going problem with the delta sensor. Researched online and read tons of stories of people with the same issue which apparently cost $1000 usd to fix!! Please make infiniti responsible for this fix or someone will get hurt or even worse, deaths.

Coming up to a stop light I press on the brake and it goes to the floor and the ABS kicks in for no reason. I almost went through the red light. All of the brake, slip, vdc lights came on suddenly. I turned the truck off and back on again and everything is fine.

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

At approximately 8k miles the dealer replaced the rotors and calipers per their service bulletin which seemed to solve the problem. Since then, periodically while driving, the brake light will illuminate when brakes are applied and the ABS system activates and the brakes begin to groan, are spongy, have less than 10% braking power. This has happened to me 5 times over 90k miles. Although I did not make the connection at the time, I believe that it was the cause of a rear end collision that I was involved in 2008 when I attempted to brake the car on the freeway but felt that the car took much too long to come to a complete stop when I quickly slammed on the brakes.the vehicle continues these symptoms until the ignition is turned off. When restarted, the problem is resolved. It has mostly only occurred to me while driving away from a parking spot but yesterday it occurred while I was driving on the freeway at speed exceeding 50 MPH. I was only able to stop the vehicle by downshifting my automatic to 1st gear while attempting to activate the emergency brake. I was fortunate that I was on a level freeway and not going down a steep incline. After I was able to safely pull over, the ignition was turned off and the car was restarted with no brake problems. Today I took the car into the infiniti dealer and they said that it was a 'common problem' but not a recall and that they would try to reprogram the computer. Reprogramming did not work and they said I would need a new ABS booster pump at a cost to me of $925. I looked up the problem on consumer websites and found that the problem is fairly common with both the 2004 nissan titan and armada and the infiniti qx56. It seems to be a problem with the c1179 code. What I discovered is that any consumers still had the problem even after they reprogrammed the computer and replaced the ABS booster pump. A service bulletin repair exists for the 2004 nissan titan (the federal safety agency item number: 10020026). This is a serious safety concern.

While applying the brake pedal vehicle failed to stop completely. However, consumer was able to stop the vehicle because the ABS system kicked in. Vehicle was taken to the dealer for inspection, and mechanic determined that the brake pads and computer system needed to be replaced, and replaced them. However, the problem recurred.
