What 204 owners told NHTSA about the 2012 Buick Lacrosse Hybrid

during a regular drive the check stabiltrack system message popped up on the dash in the middle circle and then the little car with the squiggly lines behind it popped up and the check engine light came on and started blinking. Immediately I noticed lack of steering control, the car's speed was accelerating and decelerating on its own, jerking and stalling also was observed. As of now the car sits in my driveway because I don't trust the safety of it. I literally feared my life was in danger driving it because of the lack of handling and the acceleration shifts that were so random. So I returned home, as I pulled into the yard the vehicle jerked hard while I was attempting turn into the driveway causing me to hit my mailbox and damaged the side fender and front bumper. no one was injured but the car was damaged as stated before and I'm scared to drive it anywhere. The unpredictable behavior displayed in the vehicle puts other drivers at risk as well because I can't control the vehicle properly. so I'm guessing all in all its a malfunction somewhere in the electrical system. I have read about recalls in my type of vehicle involving the ESC and it appears to be what is happening with mine. As of now it sits in my driveway I need a remedy and fast because that was my only source of transportation and I'm a single mother of four with a lot to take of and no way to do it.
