Great suv

2018 GMC Terrain Denali 4dr SUV (2.0L 4cyl Turbo 9A)
3 of 3 people found this review helpful
Owned this suv for two weeks now and we love it! Great ride, very quiet and comfortable. We thought the push pull buttons for transmission were going to be hard to get use to, but they are not! A lot nicer then the turn dial of other makes and not hard to get acquainted with at all. The only thing my wife is disappointed with is the turn dial AWD. takes some getting use to. After all the years of automatic AWD now you have to remember to select AWD when the weather calls for it

We replaced our 2016 Volvo XC70 since they stopped making it with the GMC Terrain Denali. We picked it because it had some of the same styling cues that make it a little more European/rugged rather than the American cushy Buick or Lincoln. We enjoy the technology it has and the ability to remote start on the app even if you don't pay for an expensive Onstar plan. We are a little disappointed in the turning radius, some engine noise and winter handling. Even the dealer doesn't quite understand why the SLT comes with nice Michelin's and the Denali, for as expensive as it comes with Hancook tires. It's a very nice car, but a little pricey for what you're getting in the Denali as compared to a Lincoln or Buick. The combined mpg on the Denali is 23 when the SL and SLT is 26, why? In April, we purchased new tires. Goodyear makes a very nice all-terrain tire for the Terrain. It handled the end of winter well, still some slippage in 2WD on wet pavement but very stable in AWD. We had a couple of issues in Jan 2020 with the brake assist warning coming on. It took the techs a while to diagnose because it would be off by the time the car was in the shop. They had to keep it a couple of days and was finally able to duplicate it to get a reading and fix it. It ended up to be a circuit board issue. March 2021: Our Terrain fell victim the the GM Infotainment issues. The profiles would not work correctly and the Sirius channels would display the correct channel but go to a different channel. The dealer reprogrammed and then finally swapped out the entire system. It seems to work a little better but the Nav freezes on occasion and needs to be restarted and the same problem as with other GM models, the backup camera stays on a little too long after putting the car back in drive and moving forward nearly a half a block. There have been class-action rumblings about the infotainment system. GM really needs to get a handle on this since cars today are all about the technology.

2018 Terrain. Beware.

2018 GMC Terrain SLE 4dr SUV (1.5L 4cyl Turbo 9A)
17 of 26 people found this review helpful
Noticeably smaller interior than 2017 model. A lot less rear cargo space than 2017 model. Front seats narrow. 1.5 engine anemic. Poor rear visibility. All black instrument panel looks cheap. Our 2017 Terrain is much nicer vehicle. Worst of all the button style shifter is UNSAFE!! It's cumbersome to operate and counter intuitive. Ive already had three close calls including one instance where I thought the engine was off and transmission in park and the engine restarted and the car was moving and I was halfway out of the car. VERY UNSAFE. I hate this car!!

Kinda Disappointed

2018 GMC Terrain SLE 4dr SUV (1.5L 4cyl Turbo 9A)

This is a 2018 Terrain SLE with the 2.0 turbo engine. The engine is excellent --- smooth, quiet, powerful. Gas mileage is 23 to 27 according to the driver information center. The stop-start engine control is smooth, but it's still an un-natural way to operate an engine. The transmission is excellent, very smooth. The interior is cheap looking. The steering gets the job done, but several other cars I've owned were better. The driver's seat is hard as a rock. I've had to add a couple of cushions in an attempt to get some comfort. The suspension to too firm. Every road bump or irregularity is felt, often harshly. GMC almost built a perfect vehicle, but the uncomfortable seat and ride ruined it. I'm disappointed. I have doubts I'll be keeping this vehicle for the full duration of the lease.
Nice car!
