Purchase this Vehicle November 1st 2025 as a GM certified used vehicle. Had several issues with the camera system including the backup camera. Would go offline and not be usable for days. Vehicle went back to shop several times for this with no resolution. Now February 18th 2026 at approximately 630PM EST (after sunset) on the way into work traveling on the highway the engine lost power and engine shutdown. Vehicle shifted into neutral with the indication to press the start button in order to shift into Drive. This cause all of the lights to shutdown when it tried to start the engine.

From the time i got my 2024 yukon denali i have had problems with the electrical systems not working, it was in the shop for 2 months upon delivery to me when it was brand new, and since then i have had issues with the engine racing, the start button not working, or cutting off and on , on its own, recently the motor cuts on but never turns over. It has been in the shop again for over a week now and they replaced the engine control module and it is still doing the same thing. The dealership is now telling me its a wiring issue causing it. It has been something the entire time I have owned it. I paid 90k for a vehicle that has major issues. I am looking into the Lemon law in my state of NC, and filing a complaint with GMC to see if I can get a replacement vehicle or traded.
