2005 Infiniti QX56: grinding or squealing brakes

Filed Sep 21, 2019 · Brakes · 216,000 miles · IL

When driving, the brake light comes on for no reason and causes the brakes to work inappropriately. It becomes very hard to brake. The brakes seem to fall through and there is a grinding sound from the brakes. If I turn the vehicle off, and then back on it works fine. Then it happens again sparatically.

While driving straight on interstate I-95 during rush hour at approximately 30 miles/hour, I pressed on the brakes and the pedal dropped down and started making a weird noise (like grinding sound) and the car wouldn't stop. The ABS light turned on, check engine light turned on, the pedal lost pressure and the brakes locked up. I ended up in a crash, rear-ending the vehicle in front of me. The car has now been repaired from damages from crash but mechanic found no problem with brake system. Abs sensors, calipers, disks and pads where changed as precaution but problem reappears from time to time and seems to reset when vehicle is turned off and on again (brake petal raised back up, grinding sound disappears and the check engine light and ABS light shut off). I visited two infinity dealers and both of them mentioned that it was a recurring problem with this model car and the problem was an issue with the master cylinder's design.

Randomly, I will step on the brakes and the brakes begin to pulsate. Then it sounds like grinding sound and the brake pedal loses pressure. Almost like it hit a void and dropped to the floor. I had to try and slow down vehicle to come to a stop. Calipers and pads were all changed, per dealer findings. And it continued. I do not go over 40 MPH for fear of this happening again. It's clearly and unsafe situation and the dealer claims they only hear this when people have back brakes. Guess what, I brought it to another infiniti service center, and they said the same thing even thought the other service center replaced just about everything. Another mechanic, from the service center, took me aside and said this is frequently happening with this model and it is a master cylinder issue from design. Come on infiniti, fix this!

I am having brake issues with my 2005 infiniti qx56. The brake light keeps coming on and it makes a grinding noise. It is also very hard to get it to come to a stop. Just yesterday, I almost could not get the vehicle to stop at a red light. I am also having an issue with the fuel gauge. I have run out of fuel 3 times and each time the the gauge is showing between 1/2 and 1/4 full. Back in september of 2017 we were on a major highway. All of a sudden we lost power and we were going 70 miles an hour. We were in the passing lane and we lucky to get over to the side of the road. We were almost in a severe accident. I have researched both issues online. I know that there have been recalls on these issues. When I called infiniti about this, I was told that there was in fact recalls but my vehicle was not on the recall list. Obviously, if I am having issues with both of the things and there have been recalls on both of them, my vehicle should be on this recall list. I something needs to be done about this before people are severely injured or worse.

50000 miles on it at moment and for the last 3 years my infiniti looses brake power. Last week I almost ran on a vehicle with my 6 month old son riding with me. Once the vehicle comes to complete stop after a while and once the engine is turned off and restarted the problem goes away. When it happens theres a huge grinding noise and brake pedal shakes very badly as if theres no brake on the car. Above all the vehicle has all good brakes. The brake light comes on too when this happens . As mentioned once engine is turned off and restarted everything woeks normal. I googled online and so many people with similar models have these issues. Most important the dealer doesnt ackwoleges it and says there no recall . I beleive they waiting once someonr does before they will take action.I hope some action can be taken about his killing matter.

I have a 2005 qx56. This loss of brake happens to me many time, brake light will come on while driving and if you push the brake you will hear a loud grinding noise, and pedal goes to the floor. Turn off engine and start it again it will be good again, its intermittent, you don't know when will it happen, so I always look on my dash for the brake light while driving so I know that its doing it again. I was told it was the brake booster. Very unsafe! There needs to be a recall.

When applying the brakes, the brake pedal was soft and the front tires had grinding and chattering noises like a ABS brake system malfunction. The care would not stop very well. The vehicle was going slow on dry pavement so there was not reason for ABS to activate. Continued to have this problem each of the dozen times I applied the brakes until I pulled into a costco parking lot. One of their mechanics drove the car and noticed the problem, but when we inspected it, it had nothing to do with the tire balancing that was just performed on the vehicle. I shut the vehicle off and turned it back on and the brakes worked normally. This has happened while my wife has driven the vehicle about 10 times in the last 4 years, but this was the first time it's happened with me when driving. Very dangerous. The description sited in the class action lawsuit fully describes my experience.

The brakes make a grinding noise and the car sounds as if the brakes are going out. I also have had the vdc light and brake light on as well during all this. And when it happens it keeps happening till you turn the car off and on and then it goes away. But has happened at least 15 to 20 times and seems to be happening more and more. Quite scary when you have a family and your on the interstate and you have to turn the car off and on for it to go away.

Brake problem usually occurs when driving at different speeds, even when backing-up. Steering wheel began to vibrate when pressure is applied to the brake pedal, brake dash lights comes on and the brake pedal pulsates and goes all the way down, you can hear sound from the front brakes, rubbing and grinding like it needs new brake pads the vehicle feels like it has no brakes and is hard to stop. This occurred on many occasions, we only use this sub on the weekends is our family car and sometimes it happens every weekend, the problem can be fix temporarily by stoping the vehicle put it on park turn-off the engine remove the key, turned back-on and it resets the brake system. But this problem has created to many incidents were accidents were barely avoid, we are afraid to drive the vehicle because is very scary when it happens and it may lead to an accident with the hole family. We just want infiniti/nissan to make this an immediate recall to prevent further tragedy do to the danger of this malfunction and complaints that I am sure people are posting every day to the infiniti dealers and to the federal safety agency. Thank you for you concern.

Brake problem usually occurs after a turn when accelerating to about 20 to 30 MPH. Steering wheel began to vibrate when pressure is applied to the brakes, brake dash lights comes on and the brake pedal pulsates and goes all the way to the floor. Sounds also are heard from the front brakes (rubbing and grinding). The vehicle will barely stop when this happens. Thank god we are not going at a high rate of speed when this occurs, if so, we would not be able to stop the truck in time. Problem always stops after we pull over and put the vehicle in park and turn the engine off. This has occurred on many occasions with recently several incidents in one week, otherwise it happens about once a month. We are afraid that the problem is getting worse and may lead to an accident. We love the vehicle but just want the repairs made before something happens. Also, the airbag light recently came on as well. Question; are there recalls on these problems?

Slip brake alert lighted on the dashboard followed by grinding brake noise and vehicle stopped. This happened multiple times and the scary thing is, I always have my whole family in this SUV every weekend.
