My girlfriend has a2014 sonic. Stabiitrak and engine light on. Running rough. I've seen many people saying this on different sites. They is a real problem. Chevy better take a hard look at this before there is a bigger problem. Sounds like it could cause a serious accident if it happens at higher speeds. Even in slower speeds in a busy traffic area like KC, or any other large city. Someone get back with me before we have to take more serious actions!
