This vehicle was on the showroom floor. It contained most of the accessories wanted. One of the accessories not installed, backseat VDR, was given to us free. We paid the installation cost. Overall, it is the vehicle we wanted, style, make, model, etc. at the Edmunds projected price.

I would give this a negative 182993 review if I could. Bought a 2020 Terrian brand new. Had 12 miles on it at purchase. Now it has 7k miles and has been in the shop 5 times. The rear window wiper stopped working at 140 miles. When we hit 55mph it will shift hard and shake the steering wheel. Gm told us it was safe to drive while they investigate the issue that still hasn't been taken care of. The sunroof won't close properly. It will close then the reopen and get stuck. I will never spend another time on trash GM products. The only issue that has been taken care of was the rear wiper witch they didn't even cover through warranty.

Have owned only a few days. Technology is great, but needs time to set up and get acquainted, my personal opinion is there is more technology than needed. Acceleration very good, braking is quick and comfortable. Vehicle handles smoothly and provides a comfortable ride. Push button operational controls are a bit awkward and not ergonomically designed for people with larger hands.

Bought my 2021 GMC terrain last Fall and I love it! Handles extremely well both in town and on the highway and even in snow! (AWD) It's roomy, not too bad on fuel, peppy and I love the many features it has as well. It's pretty freaky though how it will readjust itself if you are too close to the right white line, the crash alert is also pretty sweet. The 'hidden' volume control and radio channel changer...took me a while to discover they were on the back of the steering wheel! Lol For me it's an all around great upgrade from the Chevy Trax that I had.

This is a modern, well equipped SUV. The handling is very good, however, the ride is a bit stiff. The gas mileage is more like 25 on the highway. The lack of torque is evident when trying to pass any vehicle on the highway. The engine revs and struggles. The power is so terrible that I found myself driving in the slow lane. The transmission shifters are buttons placed undeneath the climate control. The shifting is terrible, you have to hunt for buttons and parking this thing is awful. Very dissapointing. Stay away.
Great overall vehicle

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

If you are wanting a quiet ride and smooth ride with a lot of standard features. This is the car for you. Pro's - Able to get the pano sunroof in the SLE package as well as the larger infotainment center. Amazing looks exterior and interior. Smooth and quiet ride. Cons Not gonna lie it gets pretty horrendous gas mileage on the 1.5L. Usually after a full tank. Mpg for the trip on a full to empty tank is about 16-19mpg *yes i do have a bit of stop and go traffic* The option not to turn off the autostop feature on the engine when the vehicle is at a stop. Overall this is my favorite car that I have owned. And the standard saftey features are a nice plus
