When starting the car this morning, I noticed that the steering wheel was driving kind of stiff and the car was kind of losing control while I was accelerating down the street. A while later in the day, my wrench light came on and then turned off, but a couple of months later a warning light came on saying Hillside assist not available, and then another warning light popped up after that one saying Service advance trac. So I turned the car off and attempted to restart it and the lights stayed on.
