Steering
3,897 of the 7,971 complaints (48%) mention steering. Steering complaints deserve prompt attention. We inspect steering components and alignment so the car tracks straight and responds predictably. See our suspension & alignment page.
Electrical System
1,474 of the 7,971 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.
Fuel/Propulsion System
1,117 of the 7,971 complaints (14%) mention the fuel system. Fuel system problems can cause stalling, hard starts and poor mileage. We test fuel delivery and related sensors to find the real cause. See our no-start diagnostics and check engine light diagnostics pages.

| P0700 | Transmission control system malfunction The transmission computer stored its own code. A scan of the transmission module shows the real fault. | 2 |
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 Chevrolet Cobalt 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 Cobalt 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 Cobalt 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 Cobalt, a pre-purchase inspection shows what the paperwork does not.
