Air Bags
612 of the 1,833 complaints (33%) mention airbags and seat belts. Airbag and restraint issues are often tied to open safety recalls, which are repaired by the manufacturer at no cost to you. Check your VIN on NHTSA's recall lookup first, and we can help with related warning lights and diagnostics. See our auto repair page.
Electrical System
281 of the 1,833 complaints (15%) 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.
Service Brakes
227 of the 1,833 complaints (12%) mention brakes. Brake complaints turn up on nearly every vehicle, and Phoenix stop-and-go traffic wears brake parts quickly. We measure pads and rotors, check calipers and fluid, and replace only what is worn. See our brake repair page.

Most Common GMC Sierra Check Engine Codes
Owners often put the exact trouble code in their NHTSA complaint. These are the codes cited most often for the Sierra. The most-cited is C1500 (manufacturer-specific chassis code), mentioned in 3 complaints. Counts reflect complaints that name a code, not every car on the road.
| Code | What it means | Complaints citing it |
|---|---|---|
| C1500 | Manufacturer-specific chassis code The meaning of this code varies by make and model, so it needs to be looked up for your vehicle and tested. | 3 |
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 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 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 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, a pre-purchase inspection shows what the paperwork does not.
