Chevrolet Sonic owners manuals
- Owners reported oil and coolant leaks, Check Engine light issues, or water pump failure. In the 1.4L turbo engine, a failed PCV diaphragm can cause Check Engine light with excessive oil consumption and rough idle. The same problems can appear also in the 1.8L engine.
- The GM service bulletin explains the problem with a leaking water pump in the 2012-2014 Sonic with a 1.4L engine. The simple solution is to change the water pump.
- Coolant leaks and suspension problems have also been reported. Overall, the 1.8L Ecotec engine seems less painful, while the 1.4L turbo needs more frequent inspection and maintenance.
