Power Train
153 of the 453 complaints (33%) 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
104 of the 453 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.
Electrical System
67 of the 453 complaints (14%) 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.

Most Common Subaru WRX Check Engine Codes
Owners often put the exact trouble code in their NHTSA complaint. These are the codes cited most often for the WRX. The most-cited is P2441 (powertrain code), mentioned in 2 complaints. Counts reflect complaints that name a code, not every car on the road.
| Code | What it means | Complaints citing it |
|---|---|---|
| P2441 | Powertrain code A scan and test is needed to confirm what this code means for your vehicle. | 2 |
| P2444 | Powertrain code A scan and test is needed to confirm what this code means for your vehicle. | 2 |
| P0171 | System too lean (bank 1) Often a vacuum leak, dirty MAF sensor, weak fuel delivery or a failing oxygen sensor. | 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 Subaru WRX Reliable in Phoenix
Arizona heat is the hardest test a Subaru will face. Batteries, belts, hoses, tires and engine oil all wear faster here, and a WRX 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 WRX 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 Subaru WRX, a pre-purchase inspection shows what the paperwork does not.
