I have a 99 Alero, and the low trac light will come on when I take off in my car then the trac off light will come on and the abs light..It feels like there is something slipping in the front in when I move foward or in reverse. Does anyone have any idea what this might be..I bought the car new in 99 other than a few minor problems it has been a very good and dependable car and I have a little over 100,000 miles on it.
