Left Front Knocking when Hitting a Bump
So my daughter has had this problem for awhile. She is driving down the road and hits one of those nipples in the road. Every time she hits one, her left front side of the car starts making a knocking noise. On Friday, she got a "Service Traction" light on her car and is now throwing a P0013, P0014 and P0203 code. Not sure if all of this is connected. She drives a 2009 Chevrolet Cobalt and it only has 50,000 miles on it. Any help would be greatly appreciated.
