I purchased a 2017 1LT about 4 months ago. Recently the car has been refusing to start through the engine start/stop button. The radio comes on fine, however the dash is completely dark, and no power or control to ac, windows, or anything else that needs the engine on (duh). Disconnected the battery and bought a new one and started fine for 2 days (new Fob key as well). This afternoon it refused to start. Lock/unlock works fine as well as trunk and remote start. Battery is fully charged and the fob is new and fully powered as well. Anyone have this issue? Any advice? Is it possible a theft occured that was unsuccessful? My neighborhood has had a few attempted thefts of camaros. Thank you
