My car first started with the abs and traction light on followed by a reduce power engine coming on causing my car to go no faster then 20mph, I would then have to pull over turn the car off wait a minute start it back up and it would turn back on normal. After getting a mechanic to check it he said a sensor was causing the problem, he reset the computer and all lights came off and no engine power reduce has came on since then. When buying the vechile I got it checked and was told it would have a throttle body issue in the future that day has come and now my traction light has come on and causes the car to shake and shift hard when the gears are switching I'm hoping and praying it doesn't cause an issue with my transmission but I was told I would have to switch out the throttle and pedals :/ I think after this investment I may start Saving for a new car and hand this one down to my father in law I love my SS but for the money I know I will spend fixing it I might as well get a new car and know if it has problems it's because of me
