About the 2020 GMC Terrain
Our scoring places the 2020 GMC Terrain at 7.2/10 overall, which translates to a Good rating for this suv. Its strongest dimension is Reliability at 8.5/10, while Performance at 6.8/10 is where it trails the competition most noticeably. It's a capable but unexceptional suv — stronger alternatives exist if you're willing to shop the segment carefully.
Reliability and safety are the two dimensions that matter most for long-term ownership costs. At 8.5/10, reliability is one of this suv's best cards — few vehicles in our database score higher on this dimension. The safety score of 7.3/10 is solid mid-pack territory. If advanced driver aids matter to you, compare standard equipment carefully and verify ratings at nhtsa.gov.
Performance at 6.8/10 is a genuine liability and a score that should factor heavily into any buying decision. The powertrain and chassis dynamics trail class rivals by a meaningful margin — don't overlook it. Tech rates a reasonable 7.6/10: the essentials are covered and well executed, but rivals at the same price often include more as standard.
Priced from $29,110–$35,330, 27 MPG, seating 5, the GMC Terrain sits in the mid-market bracket of the suv segment. The 7.3/10 value score says the pricing is fair rather than generous; cross-shop the segment before signing anything. At 6 years old, resale value, parts availability, and whether a successor model has improved on its weak points are all worth investigating before committing.
Our take: The 2020 GMC Terrain is a passable suv but not a standout one. Weaknesses in performance hold it back from being a strong recommendation. It may suit buyers with specific needs it serves well, but we'd encourage comparing at least two or three higher-scored alternatives before deciding.
