Not a tough vehicle
Disappointed in this purchase, 08/01/2021
2020 GMC Terrain SLT 4dr SUV (1.5L 4cyl Turbo 9A)

This suv is not meant for any sort of off roading despite its appearance. The underside is unprotected including the plastic gas tank. We were on a road that my Honda civic has traveled and one scape broke a bearing holding the drive shift, which in turn made the all wheel drive unusable. Had a minor slide off into a snow bank earlier and had $5k in damage to grill, bumper, fog lights. For the price, this vehicle is very fragile. What it lacks in structural integrity it does not make up in fuel economy, so as a highway traveler it is not superior. It is comfortable, quick, and fun to drive, but I am very underwhelmed after 27k miles.

Snow driving is not good

This is my 2nd Terrain. My first one drove great in the snow. I never got stuck anywhere. This Terrain does not do well at all in the snow. It leaves me stuck trying to get up thr slightest hill. I am not sure what done that made it different. They are both FWD. But overall, I love the Terrains. I love the size, the comfort, and how it drives in other weather except snow. I am thinking I will need to get an AWD going forward. Thank you!
underpowered drive train

The drive train is underpowered at 35 to 45 when trying to maintain speeds following traffic on NH roads it transmission grinds like you are in a standard shift high gear going to slow. I have to put in L mode and select the best gear when you do that the rpms go higher and stops most of the grinding I complained at the dealer when I had 1200 miles on it and was told its normal use the L mode. I have the SLT I paid in the high 30"s for this car and can't wait until Ican get out of it. It is a terrible running car when you have to feel it grinding in the drivetrain. Highway is fine at higher speeds Very disappointed in this vehicle when i bot it i got extra warrantee thought last car i am 72 not a chance I will trade and will not go back to gm. Everything else works ok and is a nice car except it runs terrible.

I bought my SLT Terrain brand new in 2021. I love this car, well at least I thought I did. It took me nearly 5 months to find the car I wanted and loved. In the last 3 months I have had it at the shop twice for major repairs the fuel pump and now the the drive shaft. Yes it’s all covered under warranty but the car only has 20,000 miles. I bought a brand new car so I wouldn’t have to be in shop and had reliable transportation. Very disappointed!

I’ve had the GMC Terrain SLE for only about a month now, but I have to say it’s a pretty solid vehicle. It has a comfortable ride, it has very good gas mileage, and it has surprisingly a lot of room between the backseat as well as the cargo area. I traded in a BMW X.3, so I knew I wasn’t getting a speed demon, However , it does have decent acceleration, either city driving or highway driving. The only fault I can see in this vehicle, is it does have some massive Blindspot‘s, in the windshield pillars. Other than that it has all the functionality, technology, safety features I need. I am very happy with this SUV so far, I can see myself buying another one in the future.

Shifty Shifter

Test drove a SLT today, first vehicle with push button transmission shifter. Hate it. Don't like looking down to hunt for the buttons and feel of no vehicle control. Other than that loved it. They should have offering for non-push button shifter. Lost a sale based on that. Also, the seats were narrow and cramping.

Purchased a 2020 GMC Terrain from Curry GMC BUICK CADILLAC was very impressed with salesman JT. He sold me the GMC Terrain that was just as he described and explained all features in detail. The Terrain is very comfortable easy to drive with all the equipment you would expect from a vehicle costing much more. And on top of driving well I was getting an overall gas mileage of 32.6 and my best was 38.2 very pleased with my purchase of the 2020 GMC Terrain SLT

This car has a nice ride to it and has all the feature I wanted and more. I am having issues with the phone to make calls out. It says the SD card is removed. the dealership is going to take a look at it. Other then that its a great car.
