Electrical System
91 of the 173 complaints (52%) 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.
Engine
32 of the 173 complaints (18%) mention the engine and cooling system. Engine and cooling complaints are best caught early in Phoenix, where heat pushes cooling systems and engine oil to their limits. We diagnose warning lights and check coolant, hoses and oil condition. See our check engine light diagnostics and oil change & maintenance pages.
Exterior Lighting
28 of the 173 complaints (16%) mention lighting and visibility. Lights, wipers and visibility items are quick to fix and are on every rideshare inspection checklist. We check them as part of our inspection prep. See our rideshare inspection prep page.

Ram 1500 Crew Cab RHO Check Engine Codes
NHTSA owner complaints rarely cite specific trouble codes for the 1500 Crew Cab RHO, 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 1500 Crew Cab RHO 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 1500 Crew Cab RHO 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 1500 Crew Cab RHO 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 1500 Crew Cab RHO, a pre-purchase inspection shows what the paperwork does not.
