2020 GMC Terrain Denali 4dr SUV (2.0L 4cyl Turbo 9A)
16 of 18 people found this review helpful
I had a 2013 Terrain and loved it but the 2020 has everything the 2013 lacked. Back seats that fold flat (with a push of a button); ac vents in the back seat; front and back cameras and sensors all around the car now. This new Terrain Denali has so much to offer for safety and comfort. We never had any problems mechanically or with accessory options on the 2013 so I'm hoping this 2020 will give us the same reliability. Very happy we purchased another Terrain!

Computer problems that have no fix

I purchased my 2021 Terrain in December 2020. I have had many computer issues with the car that make many features unavailable and there is no fix. The car is still drivable but offers new problems daily. They are intermittent but reoccurring. The dealer tells me there is currently no fix and that I have to wait for a software update. This is the first GMC car I have owned and now regret my purchase.

I feel the Terrain is a very stylish vehicle. It has great fuel economy, 30-33 mpg during the summer, mainly highway miles. When trying to pass on the highway, the turbo is far superior to the Equinox I used to own. I find the seats comfortable, and storage adequate-plus. If there is a drawback, it is acceleration/running through the gears from a stop sign or stop light. Not sure why GMC needs a 9 speed tranny. Overall, I am impressed, more so than the so-called experts. I'd buy another one, and perhaps will eventually

A better choice

We looked at all makes similar to the terrain. Didn't want leather seats, wanted easy to get in and out, getting in and out the seats. Wanted panorama roof that opened up, needed lots of leg room on second row seats. Wanted an engine that was zippy with a turbo, and good gas mileage. We traded our Mercedes R350 for the Terrain. The Terrain is a lot more zippy and not as big as the Mercedes. The Terrain had the safety features we were looking for including a towing package. We were pleasantly surprised at the fuel mileage with the 2 litre engine. The look, style is attractive, performance is really good, nice, options the price is reasonable. We got the under coating for the winter, now it is wait and see if can get 20 years out of it. We try to get 15 to 20 years out our vehicles. We got 15 years out of the Mercedes, decided to trade it off before the price of gas shot up. Smart move. All are kids are grow up and gone so the Terrain is a nice size for us. We have had the Terrain for almost a year, so gone through summer and winter. In the winter we have it all wheel drive and the rest of time in front wheel drive, the gas mileage is really great in front wheel drive. The milage in four wheel we lose about 100 k kilometers per tank of gas, still pretty good.
