Consumer Reviews for the GMCÂ Terrain
Read recent reviews for the GMCÂ Terrain
beautiful car
Steve Magg, 04/11/2023
2023 GMC Terrain Denali 4dr SUV AWD (1.5L 4cyl Turbo 9A)
Great styling, very adequate features, and ride. Not like some reviews, not sure what they are comparing to. Bought the 2023 Denali for my wife and she loves it. Some say the powertrain is weak, but I feel it is very well-suited for the size of the car. Comfortable for my 300 lbs and 6'1'', with loads of room for anything in the back. Very happy with only one slight complaint.....road … noise from rear tires is a bit loud, could use some deadening foam?
