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! - 5.0
This is my third GMC and by far the best!
By Margaret on Thursday, February 03, 2022
Absolutely love my 2021 GMC Yukon SLT. I was very surprised to get 29 mpg on the interstate. It has surpassed my late 2015 GMC Yukon. It is definitely a luxury vehicle with a premium ride. I have taken it on three trips with six passengers and it has been terrific every time.
