Engine
2,012 of the 7,054 complaints (28%) 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
1,249 of the 7,054 complaints (17%) 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.
Electrical System
920 of the 7,054 complaints (13%) mention the electrical system. Electrical problems are made worse by desert heat, which ages batteries, cables and connectors. We test the battery, starter and charging system and trace faults to the actual part. See our battery replacement and starter & alternator repair pages.

Most Common GMC Sierra 1500 Check Engine Codes
Owners often put the exact trouble code in their NHTSA complaint. These are the codes cited most often for the Sierra 1500. The most-cited is P0016 (crankshaft and camshaft position correlation (bank 1 sensor a)), mentioned in 27 complaints. Counts reflect complaints that name a code, not every car on the road.
| Code | What it means | Complaints citing it |
|---|---|---|
| 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. | 27 |
| P1098 | 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. | 23 |
| P0700 | Transmission control system malfunction The transmission computer stored its own code. A scan of the transmission module shows the real fault. | 12 |
| P0300 | Random or multiple cylinder misfire Worn spark plugs, failing ignition coils, fuel or vacuum problems. Do not ignore a flashing check engine light. | 10 |
| 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. | 9 |
| P25A2 | Powertrain code A scan and test is needed to confirm what this code means for your vehicle. | 8 |
| P0747 | Powertrain code A scan and test is needed to confirm what this code means for your vehicle. | 8 |
| P0307 | Cylinder 7 misfire Commonly a bad spark plug or ignition coil on that cylinder. | 5 |
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 Sierra 1500 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 Sierra 1500 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 Sierra 1500 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 Sierra 1500, a pre-purchase inspection shows what the paperwork does not.
