2021 GMV Terrain SLT

Stgcret, 04/19/2021
2021 GMC Terrain SLT 4dr SUV (1.5L 4cyl Turbo 9A)
As of today, April 19/2023 I still own my Terrain purchased in November 2020. It has, so far, not given me a minute's issue. The 1.5L Turbo is "okay" but the 2.0L Turbo is so much better. The Terrain is a very well thought out vehicle. Back seat flip flat at the push of a button and easily clicks back in to place. Seats are at hip height, which at 71, makes them very easy to slide … in and out. The front bucket seats are fairly comfortable with many power adjustments. The front seats could use another 1/2" to 1" of width. I would buy this beauty again. UPDATE: I purchase my 2021 GMC Terrain brand new in November 2020 before the chip shortage, that isn't an issue with the 2021 at all. I just hit 20,000 miles a couple of weeks ago and all-in-all has been a pleasure to drive. I'm a big guy of 6' 2" and 285 and I easily slide in and out of my Terrain. Quiet ride and efficient and peppy 1.5L Turbo motor, although I would have preferred the 2.0L Turbo like I had in my 2018 Terrain, but the 2020 was the last year for the 2.0L On the SLT, that I have, are many positions to adjust the front seat and I do prefer the leather over cloth seats. For a 2-row seat SUV, there is plenty of room and the seats fold down at the touch of button or pull that works with the effort of one finger. I really like the info system and Sirius Radio. I have not used the Navigation or phone interface because I just don't need to. One oddball fact I discovered though is that when you want to take out the Cabin Filter, you have to use a 5.5 mm socket and that size is difficult to find. They need to go to a more conventional size like a 6 mm or 1/4 inch. UPDATE: I drove my 2021 Terrain SLT Elevation Edition out of the dealer showroom on 11/27/2020. I am 6' 2" and 72 yrs old. I specifically like the way I can slide in and easily slide out of the Terrain. I also find the front seat very comfortable and easy to adjust and has a nice lumbar support. I don't find the road noise so bad, but maybe that is because I have Talk Radio on all the time. I do agree that a 2.0 Turbo would be a better engine option. I owned a 2018 Terrain Denali with the 2.0L and I thought I was in a rocket when I stepped on the gas. I have owned my 2021 for 31 months now and have put 21,530 miles on the ol' girl and have not had a single issue, but there was one "what were they thinking moment" the screw for the driving compartment air filter is a 5.5 mm! I did change that filter at 18,000 miles although the manual called for 30,000 miles. Such an odd and hard to find size. I have changed the oil and filter every 5,000 miles and rotated the tires. I would like to see the same vehicle but 10" to 12" longer and maybe 4" to 6" wider to fit just a bit more beefy seat like the Tahoe has. Other than that I will most likely buy another Terrain and for sure if they reinstate the 2.0L Turbo.
