When I was driving the car started to sputter and would not pick up speed. I took the car to a mechanic who ran a diagnostic test and gave me the codes to take to a Ford dealership. The sensor switch for both rear breaks where replaced. A week later same thing happened. It is currently doing the same thing. The break system light is coming on and the control system light. Nobody seems to be able to fix it. I have been driving down the highway, on private streets when the car starts to sputter and I have to turn it off and on at least 3 times before it will pick up speed and go.
