Engine
1,217 of the 3,209 complaints (37%) mention the engine and cooling system. Engine and cooling complaints are best caught early in Phoenix, where heat pushes cooling systems and engine oil to their limits. We diagnose warning lights and check coolant, hoses and oil condition. See our check engine light diagnostics and oil change & maintenance pages.
Power Train
483 of the 3,209 complaints (15%) mention the powertrain. Powertrain complaints can range from rough shifting to loss of drive. We road test, scan for stored codes and inspect fluids before recommending any repair. See our auto repair page.

Most Common GMC Terrain Check Engine Codes
Owners often put the exact trouble code in their NHTSA complaint. These are the codes cited most often for the Terrain. The most-cited is P0014 (exhaust camshaft timing over-advanced (bank 1)), mentioned in 12 complaints. Counts reflect complaints that name a code, not every car on the road.
| Code | What it means | Complaints citing it |
|---|---|---|
| P0014 | Exhaust camshaft timing over-advanced (bank 1) Commonly an oil, solenoid or timing component problem. | 12 |
| P129F | Manufacturer-specific powertrain code The meaning of this code varies by make and model, so it needs to be looked up for your vehicle and tested. | 11 |
| P0017 | Crankshaft and camshaft position correlation (bank 1 sensor B) Similar to P0016: timing chain, sensor or timing component trouble. | 9 |
| P0011 | Intake camshaft timing over-advanced (bank 1) Often an oil, variable valve timing solenoid or timing component issue. Low or dirty oil is a common trigger. | 7 |
| P0016 | Crankshaft and camshaft position correlation (bank 1 sensor A) Can point to a stretched timing chain, a failing sensor or a timing component problem. | 6 |
| P0089 | Powertrain code A scan and test is needed to confirm what this code means for your vehicle. | 5 |
| P0556 | Powertrain code A scan and test is needed to confirm what this code means for your vehicle. | 5 |
| P0420 | Catalyst efficiency below threshold (bank 1) Often a worn catalytic converter, but failing oxygen sensors or exhaust leaks can set it too. Can cause an emissions test failure. | 4 |
A code is a clue, not a diagnosis. The same code can have several causes, so we test before replacing parts. See our check engine light diagnostics, and read whether it is safe to drive with the check engine light on.

Keeping a GMC Terrain Reliable in Phoenix
Arizona heat is the hardest test a GMC will face. Batteries, belts, hoses, tires and engine oil all wear faster here, and a Terrain that spends its life in stop-and-go Valley traffic needs maintenance earlier than the owner's manual's normal schedule suggests.
Our recommendation for Terrain owners: follow the severe-service schedule, test the battery before every summer, inspect brakes and tires twice a year, and have any warning light diagnosed instead of ignored. If you are shopping for a used GMC Terrain, a pre-purchase inspection shows what the paperwork does not.
