Customers say

GMC offers a lineup of trucks and SUVs that are generally praised for their reliable performance, spacious interiors, and towing capabilities. Owners appreciate their rugged design and the comfort they provide, especially in models like the Sierra and Yukon. However, common criticisms include fuel economy issues and high pricing for some models. Despite these drawbacks, GMC vehicles are often recognized for their power, luxurious features, and off-road capabilities, making them solid choices for both daily driving and rugged use.

The truck had all the features I wanted and the price was in-line, or better with others in my search.

Best truck I have driven! Highway speeds are great and feels like I’m driving a Cadillac.

Nice truck. Awesome features, but weaker engine than I expected. My 2020 6 cylinder had more guts.

Kristen R

Reviewed a 2018 GMC Yukon on Apr. 10, 2024

Great vehicle. Tons of room for my family. Very little options because it’s a base model. But felt safer being a little higher up more like a truck.
