Electrical System
334 of the 1,845 complaints (18%) 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.
Visibility/Wiper
273 of the 1,845 complaints (14%) 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.
Air Bags
231 of the 1,845 complaints (12%) mention airbags and seat belts. Airbag and restraint issues are often tied to open safety recalls, which are repaired by the manufacturer at no cost to you. Check your VIN on NHTSA's recall lookup first, and we can help with related warning lights and diagnostics. See our auto repair page.

Most Common Subaru Legacy Check Engine Codes
Owners often put the exact trouble code in their NHTSA complaint. These are the codes cited most often for the Legacy. The most-cited is P2138 (throttle or pedal position sensor voltage correlation), mentioned in 17 complaints. Counts reflect complaints that name a code, not every car on the road.
| Code | What it means | Complaints citing it |
|---|---|---|
| P2138 | Throttle or pedal position sensor voltage correlation Failing accelerator pedal sensor or throttle sensor; can cause reduced power. | 17 |
| P0700 | Transmission control system malfunction The transmission computer stored its own code. A scan of the transmission module shows the real fault. | 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 Legacy 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 Legacy 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 Legacy 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 Legacy, a pre-purchase inspection shows what the paperwork does not.
