Summary Verdict

The 2012 Chevrolet Sonic presents a mixed reliability profile. Owners have reported common issues such as oil and coolant leaks from the engine, particularly with the 1.8L variant, and potential turbocharger problems or oil consumption with the 1.4L turbo. Automatic transmission issues like harsh shifting are also noted. Suspension components, specifically struts and shocks, can wear out, leading to a less comfortable ride. Electrical concerns like alternator failure and power window malfunctions are also documented. While the exterior and interior generally hold up well, potential buyers should be aware of these specific mechanical and electrical weak points and factor in potential repair costs.
