Glad to hear that Ford is stepping up and fixing it.
Have to say, though, that this crazy procedure the Fiesta, Focus, and a few others require that involve disconnecting the battery are precisely why I avoided those vehicles. I don't want any vehicle I have to disconnect the battery on in order to tow. Not when there are so many other good towed vehicle choices out there for similar $$ that don't require that.
With my Ford Taurus, all I have to do is run the engine 5 minutes at beginning of the day before towing, run tranny through Drive, Reverse, then to neutral, and its ready to tow up to 65 mph. I always remember that tranny procedure this way - Drive, Reverse, Neutral, as in 'Don't wReck Nothing' (DRN) :)
