2020 GMC Terrain SLT 4dr SUV (1.5L 4cyl Turbo 9A)

The sticker price drops appreciably with the ever-present incentives. Comfortable ride, nice features, and reasonable engine performance from the base engine (remember, it's a SUV, not a sports car) make this a worthwhile purchase. The Honda is lackluster, and every Toyota I've owned had numerous electrical gremlins as soon as the warranty expired. The Terrain SLT has the features I wanted, and drives well.

New 2020 Terrain

I love it. Perfect for us taller girls and very affordable. I got like 5 additional packages but the elevation package is a must for this truck. I also got the black out package so everything down to the GMC logo is black. My truck is everything and it’s such a smooth ride. $22 on half a tank (89) and $45 on E (89) I love the lil safety feature when someone is too close to ur car... it’s like a lil vibration under ur bottom to let u know something is near and to look

I bought a brand new 2020 terrain this year. I live in central Alaska where roads and temperatures are tough. Ice and snow are on the roads from October-April. I will not take my terrain out of AWD in the winter here because it just wants to slip and slide everywhere more so than most vehicles I have driven. It handles okay in winter but I plan on putting winter tires on instead of riding all seasons. The terrain doesnt have much of a get up and go but cruises at a steady and comfort. I have the slt model and it does not have heated seats/ steering wheel, roof bars, touch-less rear cargo, crash control. But it does have lane assist, great gas mileage and cheap to fill up even less than most sedans, its comfortable, roomy, and over all the SUVs I drove this one was my favorite. I am usually the only one who drives it but if I do have 2 tall people in it at once they are both very cramped. I do love how there are levers in the back where the back seats fold down to put longer items. What I am really here to say though is that my terrain has only 8500 miles on it, oil and service done at 5000 miles and my check engine light came on during a long road trip out in the freezing tundra of Alaska. I was not sure I would make it back home. I got an error message “Reduce engine power” then the terrain would not go from 0-60 without taking its time. I made it home and then to the dealership where they said it was the shutters in front of the inner cooler system. My suv had been in the dealership for over a week now, riding rough and they are trying to figure out what to do next since they had to tow it back into their shop. And in the meantime they lent me another suv that broke down on me and I am on rental car number two. The dealership has been great but I am not happy my new vehicle that I have only had for 6 months is in the shop. What will happen next?
Kudos to gmc

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.
