2024 GMC Yukon Steering Problems

I am filing this complaint regarding a serious and ongoing safety issue with my GMC Yukon Denali that began with a complete engine failure while driving on the highway with my entire family in the vehicle. While driving at highway speed (about 60–70 mph), the vehicle suddenly lost power and shifted into neutral on its own. While still moving, I tried multiple times to shift back into Drive so I could safely get off the road, but it would not engage. I was only able to coast partially onto the shoulder before the vehicle came to a complete stop, still partly exposed to traffic. The engine shut off and would not restart at all. It would not go into Drive or Neutral, and the vehicle was completely dead. And it had to be towed. The dealer later told me the engine had failed and that a new engine was installed. About a week later, I picked the vehicle up. Less than 20 minutes after leaving the dealership and getting back on the highway, smoke started coming from the vehicle and warnings appeared, messages that the engine was overheating and that I needed to stop the engine immediately. The vehicle was not drivable again and had to be towed back. I again had to arrange transportation home. A few days later, I picked the vehicle up again. Since then, I have had serious four-wheel-drive and drivetrain issues. The vehicle became stuck in 4 Low and I could not get it out for over a day. When it finally came out, the drive mode buttons stopped working correctly. Selecting 2 High sometimes puts it into 4 High, selecting Auto puts it into 2 High, and Auto mode no longer appears. Even when it shows 4 High, the steering is restricted cannot steer 100% to the right or left and the vehicle binds, pops, and jumps when turning. I believe this vehicle is unsafe and poses a serious risk.

November 12, 2025 - Turned on car and immediately noticed multiple system failure notices and very slow ability to brake. Immediately took to dealership - said battery needed to be re-charged. December 9, 2025 - turned on car and once again immediately noticed multiple system failures and very slow ability to brake. Failures were "Brake System Failure, 43 MPH Top Speed, Forward Collision System Unavailable, Service Brake Pad Monitor, Service ESC, Service Traction Control, Service Sterring Column Lock" Immediately took to dealership. Over the last 25 days in service all the dealership has told me is that their master technicians have looked it over and do not know the root cause. They are waiting for a new technician from GM. They also have another Yukon at the dealership with the same safety symptoms. No issues with the car prior to these two instances of failures. Car should not be driven.

I am the owner of a 2024 GMC Yukon (VIN: [XXX] ), purchased from Hatchett Buick GMC on [XXX]. This vehicle was purchased at a high price with the expectation that it would provide reliability and keep my family safe. Unfortunately, that is clearly not happening. The Yukon continues to suffer from severe power loss that neither the dealership nor GM technicians have been able to diagnose or repair. In addition, this vehicle is subject to an unresolved engine recall, further undermining safety and confidence in the vehicle. Multiple times while driving I have had total power loss with no warning or indicators of this happening through lights or warnings on the vehicle. This is separate from the engine recall issues I am currently experiencing as well. While driving the Yukon will lose all electrical power. The vehicle is still currently at the dealership trying to be diagnosed. It has been 2 weeks. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My vehicle stalled while driving on a busy highway & I had no option but to pull over, which left me & my family in a very dangerous position. Had to remove my daughter's wheelchair onto a tow truck as the vehicle had no power to use the hoist for her powerchair. Again, on the side of a busy road! Towed the vehicle to a GM dealership, who stated there was catastrophic engine failure & the engine had to be replaced. Had no way to transport my daughter until I got a new engine since her hoist was stuck at the dealership.
