For the record, it does not matter where you bought your Ford, as long as it was an Authorized Ford Dealer. In the same regard, it does not matter where you service your Ford, as long as it is an Authorized Ford Dealer. I buy my cars based on what dealer has the exact model and combination I want. As luck would have it, that is rarely one of the dealers close to me. No matter what make. But volvo, audi, vw, chevy, and ford have never given me a hassle servicing a car i did not buy from them. i will drive an hour to buy, but not for service.
Call around. Or drive to a local shop and have the service adviser look at it. You will have to drop it off, but many will find a way to squeeze you in.
