Electrical System

We test the battery, starter and charging system and trace faults to the actual part. See our battery replacement and starter & alternator repair pages.
Air Bags
1 of the 2 complaints (50%) 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.

Ram 3500 Cab Chassis Check Engine Codes
NHTSA owner complaints rarely cite specific trouble codes for the 3500 Cab Chassis, so we do not have a model-specific ranking to show. These are the check engine codes we see most often on vehicles in Phoenix heat, and any of them can show up on a Ram.
| Code | What it means |
|---|---|
| P0420 | Catalyst efficiency below threshold (bank 1) Often a worn catalytic converter, but failing oxygen sensors or exhaust leaks can set it too. Can cause an emissions test failure. |
| P0300 | Random or multiple cylinder misfire Worn spark plugs, failing ignition coils, fuel or vacuum problems. Do not ignore a flashing check engine light. |
| P0171 | System too lean (bank 1) Often a vacuum leak, dirty MAF sensor, weak fuel delivery or a failing oxygen sensor. |
| P0455 | EVAP system large leak Missing or loose gas cap, or a disconnected or cracked vapor hose. |

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