I have had the car back into my dealer twice now. My transmission slips and sometimes hesitates before engaging. It doesn't do it all the time, in fact there's no rhyme or reason to it. There was a service bulletin Ford issued in feb. to replace a module I believe. It was supose to fix the problem, but didn't. I'm still working with my dealer to resolve this problem. However I don't want to hang on for so long that my warranty runs out before the problem is taken care of. I get great mileage and except for the transmission, really like the vehicle.
