Engine
59 of the 243 complaints (24%) 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.
Electrical System
54 of the 243 complaints (22%) 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
49 of the 243 complaints (20%) 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.

| P0303 | Cylinder 3 misfire Commonly a bad spark plug or ignition coil on that cylinder. | 2 |
| P018C | Powertrain code A scan and test is needed to confirm what this code means for your vehicle. | 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 Ford Mustang GT350R Reliable in Phoenix
Arizona heat is the hardest test a Ford will face. Batteries, belts, hoses, tires and engine oil all wear faster here, and a Mustang GT350R 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 Mustang GT350R 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 Ford Mustang GT350R, a pre-purchase inspection shows what the paperwork does not.
