2021 GMC Terrain SLE 4dr SUV AWD (1.5L 4cyl Turbo 9A)

I was pleasantly surprised how peppy this small SUV is. I love all the safety features and the fact that I don’t have to pay so much for gas since it takes regular 87 octane. I took it on a long trip this weekend and it performed great.

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

I purchased the GMC Terrain SLE FWD and my wife loves it. It drives well, handles well, and is overall a nicer vehicle than the similar Chevy Equinox. With all the incentives that GMC had, we got it at the same price as a less equipped, base Equinox, but the GMC has much more features and overall nicer interior. The 1.5L engine is plenty for us as we are not aggressive drivers. My only sight dislike so far is the push or pull buttons for Park, Drive, Reverse. Not used to those just yet. Overall highly recommended.

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

What we like: We loved the Terrain SLT we purchased a few years ago, so in the early fall, with $8,000 in incentives, we traded it in for a 2020 model. This is a very SMART car. Lots of new features and technology to learn. We like that it allows data from the cell phones to download to the car. Nice to set up your Google Maps or Waze, go out to the car and view it on the display screen. The folding front seat is a great option. Love the huge sun roof and its push-button shade. Very quiet ride. Good acceleration. Well designed dashboard/interior lighting. We like the air-conditioning/heat vents for the back seats. The heated steering wheel gets so warm, so fast, that you must quickly turn it off. All-in-all we are very happy with our Terrain. Things we're not crazy about: Fuel. Both the salesmen and service manager said if we purchased the 1.5 Turbo engine, we could avoid expense premium gas and use mid-grade instead. But the owner's manual recommends premium gas. It says the use of anything other than premium voids the warranty. So, we bought the car under a gas-savings assumption, but now fear the dealership may not have been truthful. Can anyone confirm that this engine can safely use mid-grade fuel? Also, living in Michigan, we purchased AWD, but I am disappointed with it. The first time we drove the car in heavy snow, it became stuck. And with its wheel design, snow became packed into the rim and spokes. When we drove the car the next day, it shook violently, with the wheels out of balance by the packed ice/snow. We now keep a snow shovel in the car and use our Buick AWD in the heavier snow. Another item, I don't like where the fog lamp switch is located. It's out of site, below the steering wheel, under the fold of the dash, where it sits among other push button controls. It is hard to locate the switch while driving -- frankly, you can't turn the fog lamps on without taking your eyes off the road. So, at least until you learn the brail of it, you must operate the lamps only when the vehicle is stopped.

Unreliable where it gets below 10C

Turbo has an inner cooler that freezes up on a consistent basis, leaving you with low power to limp to a dealership to have it dealt with. I guess GMC is not acknowledging there is an issue as they don't sell enough in the northern areas to worry about due to every vehicle with this engine has this issue. Cheaper to fix than repair permanently. Dealerships are overloaded with this issue. It is not reliable in winter, can't trust a commute, can't take it on a winter vacation. Can't trust it not to freeze up. Too bad, I quite liked it otherwise.

Purchased Terrain AWD Denali MSRP of $43,780 for $30,475 after rebates and GM rewards. It has heated/cooled seats, adaptive cruise, heated rear seats, rear vision camera, lane change alert etc. Drives great and gets very good mileage.
