2015 GMC Yukon XL: brake failure

Filed Apr 7, 2024 · Brakes · TX

On several occasions, have noticed the brakes failed to operate properly when vehicle is at low speed. The pedal becomes extremely hard to push and there is almost no braking power. This has occurred in stop and go traffic and nearly caused an accident.

Brake Assist Light came on. Pierre brakes failed and had to press down hard manually to get the car to stop. Felt antilock breaks were assisting. We felt very unsafe. It’s very scary.

The brakes failed in my car causing a rear collision with an object in my driveway. After inspection from a certified gmc dealership, the brake failure was not caused by service neglect or age of brakes, it was due to the vaccum pump failure to provide pressure. This is the second time in two years this part has caused my brakes to fail. The dealership replaced the part at no cost though there is not formal recall on this part. Both times this part failed the car was in motion. The first time it was towed out of a city to be repaired as it was dangersous to drive and the second time the failure caused the vehicle to collide with a large dumpster in my driveway causing extensive damage to the rear passenger side of the car. Thankfully there was not physical damage to any persons in either of these two incidents which both were no fault of the driver or owner of the car.

I was never notified of a recall on the vacuum pump that controls the brakes. My brakes went out while driving without warning. Brought it to the dealership, and of course they only covered the recalibration of the vacuum pump but not the vacuum pump itself. Absolutely ridiculous and very expensive repair that I feel gmc should be responsible for in full.

Power breaking fails when driving at low speeds, brake pedal stiff and hard to push down to stop vehicle in both forward and reverse directions when inching forward at a stop light/sign, or parking in a parking lot in forward and reverse car keeps moving. Stopping required very hard push on the stiff brake pedal.. Braking at higher speeds less affected but sudden stops can require more force than usual as the car slows down. Problem began december 2017 rarely and intermittently, and increased to all the time by february 2019 at low speeds the power brake did not work and required much force on the brake pedal to stop vehicle every time. Brake fluid was fine and so was brake pads. Gm dealership visit showed a failure of the vacuum pump for brake line and they installed a redesigned pump which shows that the original has faulty design. They also required a belt that operates pump to be replaced as well. This seems to have fixed the problem for now but this repair has a two year guarantee. Price for me to fix over $881+tax.

While in motion the brakes went out completely in july 2015. Then while driving down the interstate at 75 MPH the brakes went out completely in 2018. Both times I was charged a deductible. Both times the complete brake system was completely replaced by a dealership. After the second incident I contacted gmc. After numerous phone calls the offered me $2000 towards a new vehicle. I was very upset with them and threatened to get a lawyer if I was hurt in this vehicle or hurt others in the future. It was a terrifying experience and I felt like I deserved more. They wouldn't even pay for the rent a car I had to use on my vacation while the brake system was replaced. I paid $70,0000 for this car, but don't want to fear loosing brakes ever again!
