2018 GMC Terrain SLE 4dr SUV (1.5L 4cyl Turbo 9A)
1 of 1 people found this review helpful
Have had this vehicle for 3 months. Have had it in the shop 3 times in the last 2 weeks. It will get up to 75 mph and 3000 rpm and will not shift. You have to completely let off the gas to make it shift. They have now replaced the TCM (Transmission Control Module) and it is worse then when I brought it in. It will not shift properly or accelerate correctly. OH, and it only has 35,000 miles. SO DISAPOINTED

2018 GMC Terrain Denali 4dr SUV (2.0L 4cyl Turbo 9A)

if you wait to buy a GMC TERRAIN DENALI until it’s 2 or 3 years old, with low mileage (under 15k miles), you can save 12-14 grand vs. the price of a new one. The 2.0 turbo has more power than any of its competitors, except the Jeep Cherokee. After driving both, the build quality, 9 speed tranny, safety features, ride, and stereo system moved the needle in GM’s favor. We love the way GMC products look now, they look rugged. I get about 27 mpg on the highway, and when you push the 2.0 turbo, it really delivers power nicely. Excellent SUV for traveling and visiting Lowe’s, Home Depot, or Walmart to load up. Very happy with the value and price point.

This is a fleet vehicle from my company and have no choice but to put up with it. I have had 8 recalls. I’ve put 30,000 miles on it last year and the seats are so uncomfortable and sit at a weird angle it drives me crazy. I’m sure it’s bad craftsmanship based on everything else. How could an engineer come up with such a horrible seat and seating position. Do we really need 4” bucket seats on a vehicle not much more powerful than my lawnmower? I’m pleading with my company to get rid of it. It’s so bad I may quit over it. It’s that bad. DON’T BIY ONE OF THESE!!!!!
