Summary Verdict
The 2014 Chevrolet Sonic presents a mixed reliability profile. The 1.8L engine is generally robust but can suffer from common oil and coolant leaks. The 1.4L turbo engine, while offering better performance, is more prone to turbocharger issues and oil consumption problems. Automatic transmissions have seen reports of harsh shifting and slipping, often requiring significant repair. Electrical issues like battery drain and infotainment glitches are also noted. The manual transmission, suspension, exterior, and interior components appear to be relatively trouble-free. Prospective buyers should be aware of potential engine and transmission concerns, especially with the turbocharged variant and automatic gearbox.
