Excellent features, nice to drive, great safety
By Research Nerd on 9/1/2026 8:54:53 PM
I bought my 2026 GMC Terrain Denali about a week ago. So far I haven't found anything I don't like about it. The Terrain drives like it's floating, super smooth ride. I love the 15" display, along with controls on the steering wheel. Adaptive cruise is one of my favorite features. The car practically drives itself. I drive approximately 80 miles per day, so the navigation is key. Took me maybe an hour to set everything up and now I just sit back and drive. BONUS, I'm averaging 30 mpg, so don't be misled by published mpg. I got the downpour metallic (grayish blue) with black leather interior. Excellent combination. I use the "camera" feature the most, especially when parking. Makes parking a breeze. ONLY downside is there is some road noise when going highway speeds, but that is literally my only complaint. - 5.0
Love the touchscreen

A nice vehicle. I got the AWD function and couldn’t be happier. Plenty of room for the kids at an affordable price. - 5.0
A blue one

To date, our experience with the 2026 Elevation has been excellent. The cabin is plush and extremely comfortable. The ride is vey smooth and although many critique the power train, we have found the AWD version to be more than adequate. The price is competitive and the entry version can be well optioned. The only negative we have is there is not an upgraded stereo. That said, the existing one is okay and can be set to individual preferences. The tablet looks a bit intimidating but is actually quite user friendly. So far we are more than pleased.
