Exterior Lighting
3,323 of the 11,853 complaints (28%) 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.
Service Brakes
2,181 of the 11,853 complaints (18%) mention brakes. Brake complaints turn up on nearly every vehicle, and Phoenix stop-and-go traffic wears brake parts quickly. We measure pads and rotors, check calipers and fluid, and replace only what is worn. See our brake repair page.
Electrical System
1,418 of the 11,853 complaints (11%) 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.

| C1252 | Manufacturer-specific chassis code The meaning of this code varies by make and model, so it needs to be looked up for your vehicle and tested. | 20 |

| P0A93 | Powertrain code A scan and test is needed to confirm what this code means for your vehicle. | 4 |
| P1121 | Manufacturer-specific powertrain code The meaning of this code varies by make and model, so it needs to be looked up for your vehicle and tested. | 4 |
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 Toyota Prius Reliable in Phoenix
Arizona heat is the hardest test a Toyota will face. Batteries, belts, hoses, tires and engine oil all wear faster here, and a Prius 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 Prius 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 Toyota Prius, a pre-purchase inspection shows what the paperwork does not.
