NHTSA Complaint #11465272 — 2011 FORD FIESTA

We have owned this vehicle for approximately two years. The vehicle would occasionally loose power/shut off while driving, specifically when slowing to a stop or turning a corner. Several times when this occurred the vehicle was being driven in heavy traffic and we were almost rear ended by drivers behind us due to the sudden stopping of the Fiesta. We initially believed that it was due to faulty oxygen sensors and had them replaced. (There was a check engine light that came on and the codes indicated an issue with the oxygen sensors.) Earlier this year the problem started again. When leaving our neighborhood, the car shut off and would not start again. The car was placed in park and would not shift out of park. After leaving the car parked on the side of the road for approximately 30 minutes, we were able to start the car and shift it out of park. It drove fine the rest of the day. The next day the car again lost power while driving. We were unable to shift the car out of drive and had to have it towed. It has been sitting at the dealership since the beginning of February awaiting a replacement Transmission Control Module, which we have been told is on back order. We have purchased three used/rebuilt TCMs and taken them to the dealer (one was pulled from a car at a local junk yard and two were purchased online) to have them installed. None of the parts that we provided were able to be programmed by dealership after being installed. We were originally told by the dealership that a new replacement parts from Ford are on backorder and aren't expected to be received for at least 6 months. Our local Ford dealership (where our vehicle currently is awaiting repairs) has 8 Focus and Fiesta's sitting awaiting new TCMs.
