Why it stands out

The 2018 GMC Terrain presents a significant shift from its predecessor with a more conservatively redesigned exterior, moving away from its bold and boxy styling. While it retains some appeal with a spacious interior and multiple trim options, it has faced criticism regarding value for money due to higher pricing compared to competitors offering better safety ratings and more engaging performance. The Terrain's refined interior boasts modern technology like an 8-inch touchscreen with Apple CarPlay and Android Auto, but some controls can be distracting to use. Though spacious, its cargo capacity does lag behind key rivals like the Honda CR-V. The driving experience is adequate, especially with the more robust turbocharged 2.0L engine; however, some drivers report minor concerns about brake sensitivity. Overall, the Terrain has its strengths, particularly in comfort and features, but buyers may want to weigh these against noted shortcomings.
