Engine
239 of the 954 complaints (25%) 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.
Power Train
231 of the 954 complaints (24%) 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.
Electrical System
227 of the 954 complaints (23%) 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 Chevrolet Sonic Check Engine Codes
Owners often put the exact trouble code in their NHTSA complaint. These are the codes cited most often for the Sonic. The most-cited is P2138 (throttle or pedal position sensor voltage correlation), mentioned in 6 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. | 6 |
| P0011 | Intake camshaft timing over-advanced (bank 1) Often an oil, variable valve timing solenoid or timing component issue. Low or dirty oil is a common trigger. | 6 |
| P0171 | System too lean (bank 1) Often a vacuum leak, dirty MAF sensor, weak fuel delivery or a failing oxygen sensor. | 6 |
| P0299 | Turbocharger underboost Boost leak, failing turbo or wastegate, or a boost sensor issue. | 2 |
| U0101 | Lost communication with transmission control module Wiring, battery or module power fault. | 2 |
| P0420 | Catalyst efficiency below threshold (bank 1) Often a worn catalytic converter, but failing oxygen sensors or exhaust leaks can set it too. Can cause an emissions test failure. | 2 |
| C0196 | 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. | 2 |
| C0287 | 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. | 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 Chevrolet Sonic Reliable in Phoenix
Arizona heat is the hardest test a Chevrolet will face. Batteries, belts, hoses, tires and engine oil all wear faster here, and a Sonic 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 Sonic 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 Chevrolet Sonic, a pre-purchase inspection shows what the paperwork does not.
