What 147 owners told NHTSA about the 2024 GMC Yukon Denali Xl 1500

Driving on highway at 80 MPH and accelerator stopped working and car turned off. We had to coast off toll rd and hope for the best. No warning and happened with our whole family in the car. I had a recall notice from manufacturer but last time I tried contacting manufacturer/dealer they said no resolution was available to repair recall yet and that I couldn’t drop off my vehicle.

There currently is a serious recall on this vehicle and there is no remedy available. I’ve called the dealership and they confirmed this information. The service department claimed the sales department may be able to help me and then sales said it was a service dept issue. I have children who have been placed at risk as they have been traveling in this vehicle since April 2024.

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.

The car has made a high pitched metallic rattle on cold start ever since I received it. I have taken it into the dealership multiple times for this and have had the lifters in the engine replaced but they never addressed the other noise, which I have video evidence of. The car died at 24,740 miles on the odometer in the middle of a highway in the middle of nowhere. The vehicle started to feel like it was braking on acceleration, there were no warning lights. The vehicle just lost acceleration power and I had to coast to the shoulder. Luckily I had time to pull over without interference from other traffic. Once on the side of the road I tried to crank the car again and a very loud metallic sound happened that sounded like I threw a wrench in a fan. The car lost electrical power very shortly after. I called onstar for help and she asked if I could shift the car into neutral which I could not. They had problems finding anyone that wasn’t hours out that could come tow my car and suggested that I try to find an alternate method of transportation since a wrecker service probably wouldn’t transport my entire family. Uber was not around to get me, Lyft was not around to get me and there was no taxi service. I had to rely on the local fire department to rescue us as it was hours with myself, my two children and my dog on the side of the road in 90F heat. Once at the dealership they confirmed it was indeed a catastrophic engine failure and I am currently waiting months for a back ordered engine with a rental I’m paying partially out of pocket for, in a car that’s entirely way too small for my family with no ETA on the engine in sight. I know multiple people personally who this has also happened to, same exact scenario and same exact engine just different model years.
