Air Bags

Check your VIN on NHTSA's recall lookup first, and we can help with related warning lights and diagnostics. See our auto repair page.
Tires
6 of the 38 complaints (15%) mention tires and wheels. Tire and wheel complaints are often about wear, vibration or pressure warnings. We check tires, balance and alignment, which matters in Phoenix where heat accelerates tire wear. See our suspension & alignment page.
Electrical System
5 of the 38 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.

Keeping a Chevrolet Express 3500 12 Passenger Reliable in Phoenix
Arizona heat is the hardest test a Chevrolet will face. Batteries, belts, hoses, tires and engine oil all wear faster here, and a Express 3500 12 Passenger 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 Express 3500 12 Passenger 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 Chevrolet Express 3500 12 Passenger, a pre-purchase inspection shows what the paperwork does not.
