When I accelerate and get to 40 mph the car begins to shake randomly, intermittently. Then the service engine light came on, then the traction control shut off and the light to service traction control came on then the car drop the speed from 60 mph to 10-20 mph! when I tried to accelerate it did nothing ! the speed wouldn't increase at all then it started running fine and then a few miles down the road it did the same thing, dropped speed from 60 to 10-20 mph! I pulled over and shut the car off and when I restarted it the same lights were on and when I tried pulling away it would only go up to 10-20 mph for a few miles then it got up to 60 mph for a few miles just to drop again! I had my 11 month old grandson in the car that was dangerous! I was on townline road and manito blacktop that are very high traffic.
