Just a brief notice on excellent Tesla service. My MS85 would not charge the other night and displayed "Contact Tesla Service" and "Check Power Source and Charge Cable" on the display. I contacted the Rockville, MD SC and Erick pulled my log and said bring the UMC cable with you. They quickly determined that the UMC had gone bad, installed the titanium shield, and off I went. Since then, no problems charging. What excellent service!
