NHTSA Complaint #11459472 — 2012 CHEVROLET CAPTIVA SPORT

I am not sure what component could be one could be several. When I pulled into my driveway and put it in park. The engine light came on and the stereo went off. When checking the stereo would not turn back on and nothing on the instrument panel would work, heater/air conditioning, rear wipers, heated seats, hazard lights, the parking/emergency break literally nothing. So I turned the key in the ignition to the off position took the key out and the engine continued to run? I called onstar from the vehicle and realized that didn't work either so I had called from my cell. They advices me to call a mechanic. Unable to do so as it was 9pm and not was mechanic shop was available I looked online. I ended up pulling the fuel relay switch and waited several minutes for it to finally die then I undid the negative battery cable. Tried again the next day and same thing happened. It is available for inspection as I have no clue as to if and when it can be fixed. My safety was at risk due to the vehicle not shutting off and a fire/explosion could happen. The safety feature or requirement of the hazard lights (good thing I wasn't on the freeway) the parking/emergency break no need to explained this. Unable to call for emergency with onstar equipped vehicle and who know what else could be wrong. Unknown if anyone else has a verified claim but it seems to be a problem with this vehicle and no it has not been inspected but will be taking to a shop Monday morning! No lights/lamps/warnings were on or appeared prior to the engine light turning on with all this at the same time.
