Had my b max a few years now, had someone crash in to me and the insurance replaced the door, after it was fixed I had a errors message up saying the door was open which it was not. Took it back to the garage and they fixed it in minutes roll on another year and the message came back and went to lock the car this morning and its now refusing to lock stating that the drivers door is open. Any ideas before I get charged an arm and a leg from Ford?
