2021 GMC Terrain

The GMC Terrain was originally expected to be refreshed for the 2021 model year, however, due to complications caused by the Coronavirus pandemic, the changes were pushed into the 2022 model year (see more 2022 GMC Terrain info).

As such, the fourth model year of the second-generation Terrain sees very few changes from the 2020 model year.
