I traded my Toyota 4Runner for a 2024 Sierra 1500 Duramax 3.0 because I wanted better towing capabilities for our frequent cross-country trips. My check engine light came on within the first month, right before I was supposed to head out on a long trip. The local dealer reset it but couldn’t find a problem. The same thing happened a couple of months later with the same result. Then about a month later, again right before I was supposed to take a long trip, the light came back on and I got a message that the acceleration had been limited. This time the dealer (a different one) said it’s a charge air pump and that one has been ordered. I was advised to not drive long distances until the repair was completed. So I changed my travel plans and waited for the new part. A week later I was told that the part is back ordered with no ETA. I called GMC and they told me that they would look into it. After another week and a couple more calls GMC elevated the problem to expedited status. From what I can tell all this means is that it’s been assigned to another person who tracks it and calls me once a week to tell that nothing has changed. So the truck is still sitting at the dealership and has been basically unusable for over a month. The bottom line is that the truck has been unusable for a total of 6 weeks and counting since I bought it 10 months ago and has caused me to cancel two trips. I’ve told GMC that I’d like a buyback but they claim that this particular problem doesn’t rise to those standards. I understand that in a way because the problem and repair seem rather simple, except that GMC can’t get the xxxx part. At this point I have no confidence in the truck and plan to trade it as soon as possible.

BEWARE: My 2024 GMC Sierra Denali Ultimate lost all power — no steering, no brakes — while I was driving. This known engine defect is under active recall and could have resulted in a fatal accident. Despite the severity, Classic Buick GMC Arlington and GM refused a buyback and offered no amicable solution. Replacement engines have at least a 1-month wait, and even those are showing issues. I paid nearly $90K for a vehicle that is now unsafe and severely depreciated. GM is not standing behind its brand, and this dealership failed to do right by the customer.

I love it the look the interior mine is a red one and it looks so good and it’s my baby and it runs so good and the technology is off the chain
