The stabilitrak light on the dash comes on then it says service stabilitrak system in the drivers info window, the light on the dash stays on for stabilitrak then the engine light comes on. While driving home the stabilitrak light goes off and the drivers information window starts saying service AWD system. Speedometer starts bouncing to 0 and the speed I am going, and while the car is trying to shift there is a jerking between gears. Stopped at stoplight the car died, started right back up, drove to the nearest parking lot parked shut it off then it wouldn't restart. Sat for about 10 minutes then it started back up and was able to get it home but while driving it still had engine light on on the dash and the drivers info window was saying service stabilitrak system service AWD system, it was still jerking when shifting gears, and speedomenter was still doing the bouncing as described above. Any ideas?
