Back glass in the lift gate rattles loudly, literally moving up and down. It has been in shop 4 times, they hear it and see it, but can't figure out how to fix it. Had to file a claim with GMC. Very disappointed. Most of trim on inside is cheap plastic and poorly assembled. The ride is as good as the previous model. Turns and handles like a car, not a truck.…

Pricey but worth it
by Mark on Saturday, January 28, 2023
Let’s be real here, all SUVs are pricey these days, even cheaper know cars like Kia’s. Then it gets more expensive with full-size SUVs, and desirable ones like the GM brand. My Yukon wasn’t cheap by any means, but I knew that going in. It is huge, comfortable, and has all the features that I could need and want. The gas mileage is just horrible, as expected, but I knew I wasn’t buying a Prius here. My biggest complaint is with GM, they nickel and dime you to death with ridiculous add-on subscription based services. Even the My GM app costs $15/month, absurd, and this service used to be free!…

Display not working !
by Martin J on Wednesday, July 16, 2025
I just bought a Yukon 2025 first days works great. After one week this nightmare started. Display not showing anything. We lost control of A/C in front side, not radio ,not gps . I took it to gmc dealer to get repaired. I just lost my time , they told me, they replaced the radio but the same issue happened , before I left the dealer. They say “We have to order a new radio or display. The one that we replaced its bad”.I have to wait until parts is received. Because it’s a special order!!! Display looks great , but honestly it’s a piece of garbage ! First payment of $70k is coming. 😒…
