The Terrain, a mainstay of GMC's lineup since 2010, is a small SUV with seating up to 5. Exceeding the average MPG (miles per gallon) for its class, it reduces fuel costs and the carbon footprint. The Terrain has offered Android Auto since 2021 and Apple CarPlay since 2018. With optional all-wheel drive (AWD), it handles mud, snow, and sand with ease. GMC offers a 3-year, 36,000-mile basic warranty, and a 5-year, 60,000-mile powertrain warranty on its lineup.

The 2018 GMC Terrain is average compared to all vehicles.

Comparison to all vehicles.  This plot shows RSC safety scores on the horizontal axis vs. the number of vehicles with each safety score (depicted by bar height and percentages at the bottom). Colors reflect vehicle safety, ranging from red (not that safe) to green (safer). For reference, a score of 0 implies a 0.15% chance of driver death (13% chance of driver injury) over 15 years, and a score of 100 reflects a 0.016% chance (1.4% chance of driver injury). The 2018 GMC Terrain has a score of 79, implying a 0.043% chance of driver death (3.9% chance of injury). If equipped with optional advanced driver safety features, the chance of death falls to 0.038%, and the chance of injury falls to 3.4%.

We estimate that the 2018 GMC Terrain has a vehicle lifetime fatality chance of 0.0435% and a vehicle lifetime injury chance of 4.9659%, meaning the average driver has a 0.0435% chance of dying in an accident if they drive the car under regular conditions for fifteen years, and a 4.9659% chance of being injured.

Compared to the average vehicle, the 2018 GMC Terrain is 7% less likely to result in a fatal accident. Compared to other suvs, the 2018 GMC Terrain is 7% more likely to result in a fatal accident.

2018 GMC Terrain offers AEB optionally. With AEB, the vehicle lifetime fatality chance drops by 12%.
