My 2024 Yukon XL (purchased December 2024) has been in the dealership ten times within the first 8,500 miles, primarily due to OnStar intermittently shutting off and the Super Cruise system not functioning.
To date, the dealership has replaced three OnStar modules, a camera, the radio, and another control module. They also identified a faulty pin in a CAN bus connector. GM engineering has been involved, and multiple software updates have been performed.
After the eighth visit—while the vehicle was still inoperative at the dealership—I requested a buyback. GM denied the request, stating the issue was expected to be resolved that same week. I found this unusual, as the vehicle was still actively experiencing the problem at the time of denial.
Additionally, I have approximately $10,000 in modifications on the vehicle, none of which void the warranty. However, I was informed those costs would not be reimbursed if a buyback were approved.
Following the tenth visit, the vehicle has been operating correctly for the past 1,500 miles, so I have not pursued further action with GM. My preference was a replacement vehicle with the same make, model, and options. I was told that would only be possible through a buyback at the original purchase price, which was ultimately denied.
If the issue occurs again, I will be contacting GM and pursuing remedies available under Texas lemon law.
