2023 GMC Yukon XL: brake failure

Filed Aug 1, 2026 · Brakes · CA

I got into my car to run some errands. As I drove away from my house, I made a left turn downhill. I noticed vehicles ahead, so I began to slow down. At that moment, I was driving between 20 and 25 mph. When I tried to brake, my brakes failed and started flashing a brake failure warning light. I kept pumping the brake pedal, and eventually, the car slowed down and came to a stop. I turned on my hazard lights, and immediately returned home. My nephew and I were both in the car. Our live flashed in front of us. Thankfully, there were no vehicles directly in front of me or pedestrians. This could have turned out to be the worst day of my life if anyone had been injured.

Catastrophic brake system failure. When leaving my home in Baltimore County, MD, at approx. 10:00am on February 3rd, my vehicle started up normally. As I descended down a hill in our neighborhood the brake system failed and the vehicle would not stop. By standing on the brake pedal I slowed enough to put the vehicle in park as I entered an intersection with the main road. I have since learned this is the 3rd GMC Yukon (years 2023-2024) that has had the same brake failure in 24 hours in our community.

My vehicle’s engine failed for the second time while driving on the road. The first time a few months ago while my wife was driving. The engine failed and brakes failed. Fortunately she was on a back road a coasted to a stop. Car was towed to dealership. They said there was no problem. Received recall letter about a month ago outlining this issue. Yesterday, [XXX], I was driving with my daughter and the car stopped again while driving. I was in traffic and narrowly missed an accident. Gwinnett county police came to the scene and towed the vehicle to the dealership. I am not sure if the female officer made a report. But she requested the tow truck because I was blocking traffic. We often drive on the highway for work commutes. This could have happened and anyone in my family could have been fatally injured. I would like GMC purchase this vehicle back or replace with a safer model comparable or better. The service department called me this morning from Jim Ellis GMC in Buford, Georgia 678‑902‑8677, 3600 Buford Drive 30519.I was told that there is no recall for my truck. He told me that there is a safety investigation for a recall. I told him I can bring the letter. He decline. I asked for a courtesy vehicle. He said no, he would have to make a report and it would be up to 48 hours. Once it’s reviewed , then I could go to enterprise car rental to pick up a car. Maybe. The first time Rick Hendrick GMC Duluth , Ga 470‑822‑3779, 3344 Commerce Ave, Duluth, ga had my truck for about 2 weeks. No fix. No courtesy vehicle or rental. Now I’m without my vehicle for unlimited time. The Jim Elis tech, did acknowledge that there is no fix for what is going on. The local GMC dealers are not making this easy or putting the safety of its customers as a priority. These trucks are NOT safe on the road. This truck cost nearly $100,000 and it is not safe to drive.GMC has a record of the 1st service incident and this latest just happened yesterday.

I was driving on a highway with my [XXX] son and 2 dogs when without any warning the vehicle just stopped and completely went dead. I was unable to turn on the hazards so I called 911, the police came within minutes and surrounded the vehicle to keep us from being crashed into. The brakes failed to work, the hazard lights would not work, the doors would not open other than the driver door. The police had to help remove my child and 2 dogs from the vehicle through the driver door. The vehicle could not be put into neutral so the police had to tow the vehicle from the middle of the highway. The result could have been deadly. The vehicle was completely dead with absolutely no function. After the police towed it to the police tow facility it was then towed to the GMC dealership I purchased the vehicle from. The dealership is Jim Curly GMC in Keyport NJ. The dealership has had the vehicle since Saturday and is claiming to not know what is wrong with the vehicle.
