GMC Terrain engines and body systems show three common issues grouped by location and function. In the HVAC system, an A/C condenser leak causes weak cooling and oily residue. The Terrain often needs a new A/C condenser and line seals, then evacuate and recharge service. In the evaporative emissions system, a stuck EVAP valve or purge solenoid triggers code P0496. Expect hard starts after refueling and occasional rough idle on this Terrain. Replace the EVAP valve, inspect vent lines for blockage, and clear stored faults. In the engine timing circuit, clogged VVT solenoids cause cam misalignment and unstable idle. Change oil on schedule, verify oil pressure, and replace any failed VVT solenoid. After repair, perform an idle relearn and confirm stable trims with a scan tool. Across GMC Terrain models, validate cooling performance and purge operation during a road test.
