My first SUV and I’m loving it.
Stan K., Bradenton, FL, 12/12/2017
2018 GMC Terrain Denali 4dr SUV (2.0L 4cyl Turbo 9A)
I’ve had my fully loaded Terrain Denali for several weeks now and it just keeps growing on me. He 2.0T really shoves you back in your seat and the 9-Speed auto is extremely smooth and responsive for having that many gears. Auto stop/start does take some getting used to though. Soft touch materials abound and most things feel like real quality to me. Mileage is decent and would no … doubt be better if I could keep my right foot out of the Turbo. Cargo space is good. It’s fairly quiet as well though there is of course a bit more noise from the back compared to the sedans I’ve had prior. The new updated GMC Intellilink looks great and is easy to set up and use. Give one a test drive and try the Terrain out for yourself.
At 5 year point - still a great vehicle

2018 GMC Terrain Denali 4dr SUV (2.0L 4cyl Turbo 9A)
I downsized from a medium-sized SUV - so this has less cargo space and passenger capacity. But I rarely used the third row seating in my previous vehicle (rated at 7 passengers - but that counts 3 in the third row which would be difficult to get into and far too cramped) so this 5 passenger compact SUV more tha meets my needs, and with the ability to fold down flat all of the second row, … and even the passenger front seat, it will meet all my cargo needs. Also downsized from a 6 cylinder to this 4 cylinder turbo - and with the reduced weight, and extra transmission speeds, don't miss the bigger engine at all - this has even more pickup, and the braking is very good, and the mileage improvement more than offsets the extra cost for premium gas. Start-Stop technology easy to get used to, as is the push-pull transmission selectors. Much improved navigation system; great intuitive controls. Excellent safety features - crash avoidance, parking assist; birdseye view cameras. Excellent sound system and lighting package. Start of the art dash board displays and steering wheel controls. Very comfortable seats.
After 5 years, still find the ease of driving, the power when needed of the 2liter turbocharged engine, the comfort and technology make this a great vehicle. Can't see getting any future vehicle without the composite birdseye camera display that makes parking so much easier. Great Bose factory sound system. No significant repairs - a few downloaded tech updates. One battery replacement at 4 year point. Fit & finish still looking great.
Now just past the 6 year "birthday" for this vehicle. Still very pleased with its features and performance. Hasn't required anything but usual maintenance. Trouble free. Only been on a few longish drives (roundtrips of less than 300 miles) - mileage just short of 47,000. No complaints and continuing to thoroughly enjoy.
My third GMC

2018 GMC Terrain Denali 4dr SUV (2.0L 4cyl Turbo 9A)
Don't be fooled by the experts giving you the "high price" bit. I found the Terrain Denali quite affordable especially with the options that are offered. Many are not available on the foreign SUV's. The 2L turbo engine has more than enough power for quick takeoffs or merging onto interstates. Be careful, this car will actually "lay rubber." Transmission is smooth, you can seldom … feel when it shifts. The vented leather seats are great for the hot summer days of Florida. Safety is fantastic with the blind spot mirrors, collision indicator, and the back-up camera. My wife (5 feet tall) would much rather drive the Terrain because of the ease of the automatic parking and the memory seats and power lift-gate. I plan on replacing this vehicle with another GMC Terrain. It's a lot of SUV for the money. I've had this SUV for six months now, and have about 5000 trouble free miles on it.
AUTO Stop function stop working with no fix.

2018 GMC Terrain Denali 4dr SUV (2.0L 4cyl Turbo 9A)
I bought a 2018 GMC Terrain Denali. Loved it right away. Lots of options for a price that worked with my budget. Then... I was at a stop light and the auto stop function stopped the engine. When I put my foot on the gas - the car would not start again. I was soooooo lucky that the person behind me was paying attention and I did not get rear-ended. The problem is that you cannot get … the Terrain shifted into Neutral to move it off the street. Actually, my car wouldn't turn off. The engine wouldn't start but the rest of the car wouldn't turn off. Weird. Had it towed to GMC and they said they had no idea what was wrong - they're words. They kept it for a week and replaced a battery cable. Got it back and drove it for about 3 weeks and the same thing happened. Had it towed to GMC. They kept my car again for a week and this time replaced the starter. GMC actually paid for 1/2 of the starter so obviously there is a problem. Sold the car to the dealership as I was scared to death this was going to keep happening - wish that GMC would've allowed the driver to turn the Auto-Stop function off. Now I feel safe and secure driving my Honda.

Which Terrain does Edmunds recommend?
We think the SLE with the Driver Alert I package gets you all the basic safety and technology features you need, plus quite a few you'll want. However, buyers who want a full suite of active safety features, including forward collision mitigation with automatic braking and lane departure intervention, will need to upgrade to the SLT and the Driver Alert II package. In either case, we also recommend upgrading from the base engine, as the 2.0-liter dramatically improves the driving experience without a serious mileage penalty.
Full Edmunds Review: 2018 GMC Terrain SUV
Driving
6.0The base engine lacks power, the transmission is slow-witted, and the powertrain's focus on fuel economy all but eliminates snappy acceleration and quick pedal response. Elsewhere it's better. The brakes feel good, and though it's no sport SUV, the Terrain handles curves and corners with composure.
Comfort
6.5Poorly placed central air vents and stifling leather upholstery aside, the Terrain is quite comfortable, at least at rest. On the road, it's prone to regular low-impact shock, vibration and jostling on even moderately rough road. The seats are good, though, and the cabin keeps outside noise at bay.
Interior
6.0The interior is attractive and well-configured, but some controls are awkwardly placed. Taller drivers will want the steering wheel to extend farther. The panoramic sunroof cuts into rear headroom for taller folks, but overall this is a roomy cabin with good space for shoulders, legs and elbows.
Utility
7.0The Terrain doesn't offer an abundance of cargo space compared to some rivals, but can handle most routine hauling and cargo needs. Some of its more thoughtful features — such as small trays and cubbies and especially a fold-flat front passenger seat — offer an edge.
Technology
7.5The Terrain deserves high marks for its tech, improving on the mediocre offerings of past models. Plenty of features are standard throughout the lineup, multiple driver aids are available, and six USB ports help ensure that all devices get charged. Navigation comes with strings attached, though.
