it happened to me, i took it back to ford dealer and they fixed it, its that faulty cruise control/brake thing, i couldnt go in more details, just b/c i had this fixed on my 04 trac awhile ago. they had tried to pull a trick on me, so they might with u too. they had said my tires mounted on the vehicle werent factory spec and that was the reason for the cruise control not working, b/c the tires were throwing the speed sensor off. so i just gave the excuse, that even 1/2 inch of tire aint goin to make the difference from the cruise control coming on. so incase they say that to u.
