Electrical System
133 of the 384 complaints (34%) 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
72 of the 384 complaints (18%) 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.
Engine
63 of the 384 complaints (16%) 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.

Keeping a Ram 2500 Mega Cab 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 2500 Mega Cab 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 2500 Mega Cab 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 2500 Mega Cab, a pre-purchase inspection shows what the paperwork does not.
