A compact SUV offered with two very different engines across its production run — the 3.6L V6 covered here, and a 2.4L four-cylinder that shares the Chevrolet Equinox's well-known oil consumption concern.
The Terrain's compact SUV body is a comfortable, unstressed load for this V6 — notably more relaxed than the same platform's more common 2.4L four-cylinder option, which carries a completely different and more cautious risk profile.
This is one of the more important engine-identification checks on this site: the Terrain's base 2.4L engine shares the Chevrolet Equinox's well-documented oil consumption issue, while this 3.6L V6 does not.
This is about the car itself — for engine-specific failure points, see the dedicated engine page below.
This V6 Terrain avoids the well-documented oil consumption issue found on the same model's 2.4L four-cylinder option. Full detail on this V6's own timing chain consideration lives on the dedicated engine page.
FULL ENGINE BREAKDOWNGMC 3.6L V6 (SIDI) — Reliable or Not →This is the single most important check on any used Terrain from this generation: confirm which engine the specific car has before evaluating anything else — a 2.4L carries meaningfully different risk than this 3.6L V6.
Listen for a rattle on cold start or a persistent ticking at idle, the timing chain and valve lifter check described on the engine page.
Ask about fuel economy expectations realistically, since the V6's thirst is a genuine trade-off for sidestepping the four-cylinder's documented issue.
