Rattles
By Nancy | on Monday, October 19, 2020
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.… - 5.0
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!… - 1.0
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. 😒…
