My service center, Owings Mills Maryland, has always been great and treated me with great respect. They are always responsive and do a very reliable job whenever there are problems, which are few and far between. In fact, my Model S P85 (bought in early 2013) and Model 3 dual motor performance have required very few repairs (the Model 3 none) (the Model S a drive train replacement). So bad experiences with Tesla have not been among mine.
