2010-present
The GMC Terrain is a compact SUV that competes with the Chevrolet Equinox. It shares the same platform but has a more distinctive design and slightly more upscale interior. The 2nd generation (2018+) is a big improvement.

GM's 4.3L V6 and early LS-series V8 engines rarely have head gasket issues. The Duramax diesel, however, can develop head gasket failures from high cylinder pressures — a $3,000-$6,000 repair.
$1,000 – $3,000
GM trucks and SUVs use hub assemblies that include the ABS sensor. Replacement is straightforward but costs $200-$400 per wheel.
$200 – $600 per wheel
GM V8 engines (LS/LT series) still use traditional spark plug wires. AC Delco or MSD wires are recommended.
$50 – $200 (set)
The Terrain follows the same advice as the Equinox — avoid the 2010-2017 2.4L engine. The 2018+ with the 1.5T is a significant improvement. For a compact SUV, the Terrain Denali offers a luxurious interior at a reasonable price. However, better options exist from Honda (CR-V) and Toyota (RAV4) if reliability is your priority.
