Service Brakes
36 of the 151 complaints (23%) 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.
Electrical System
28 of the 151 complaints (18%) 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.
Power Train
22 of the 151 complaints (14%) 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.

Keeping a Chevrolet Express Passenger 3500 12 Pass 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 Passenger 3500 12 Pass 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 Passenger 3500 12 Pass 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 Passenger 3500 12 Pass, a pre-purchase inspection shows what the paperwork does not.
