My car went to the Rockville, MD service center a few days ago for a 12v battery issue. Since I'm quick to criticize Tesla I think it's only fair to also be quick to praise. In this situation a tusami of praise is due. Here's why: Great communication: the service center stayed in constant touch with me by phone about the nature of the repairs needed and the progress of the work. Doing more than I asked: The 12v battery had a failed cell so it was replaced. That's all I thought needed to be done but they also told me I had a drivetrain issue (the dreaded milling) which I didn't even notice. They replaced the drivetrain wiithout me even asking. Accomodating my schedule: The day they picked up my car (valet service) I flew to Chicago for a 3-day conference. The work on the car was completed within 48 hours but I woudn't get home for another day. No problem -- valet service was rescheduled to deliver the car the morning after my midnight arrival home. This is what top-notch service is all about.
