Electrical System
207 of the 509 complaints (40%) 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
116 of the 509 complaints (22%) 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.
Fuel/Propulsion System
112 of the 509 complaints (22%) 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.

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