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.

Nice but underpowered

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.

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
