2012 Jeep Grand Cherokee stability control problems

Alternator / electrical issues- november 4, 2016 my wife was taking our son to school when she began getting a burning smell from under the hood. After dropping off my son, she pulled over and noticed smoke coming from under the hood. She cut the car off, initially thinking it just overheated. We left the car in the school parking lot overnight hoping it would start up the next day. I tried to start the car, but it wouldn't start and the key got stuck in the ignition.

In feb 2016 was driving through town and my dashboard and jeep started acting crazy and it just totally died as I tried pulling into gas station, was now blocking entrance/exit. Totally dead, couldn't put it in neutral and hazards didn't work. Replaced tipm costing me $1300. Then in oct 2016, jeep dashboard started going crazy again and died as I'm driving and turning in the middle of an intersection! Everything dead, no hazards, lights anything and it was pitch black. I was lucky I didn't get hit.
