I got up early this am to take my dog to the groomer. When I returned to the car I got a passel of warnings indicating a 12v battery issue and to pull over. It then went black. I called Tesla Roadside Assist, and they were very responsive, but indicated that the local TM Ranger (Tucson) would not be used, and they'd have to flat-bed it to Scottsdale, 120 miles away. So off it goes. I was then informed a few hours later by the SC that they'd have to run a one hour "Diagnostic" and that would cost $125. My Tess is a Classic 2012 with 62,000 miles. In the event the problem is battery or drive train related, the costs will be covered under 8 year battery/drive train warranty. Not exactly sure what else it could be related to. The logs seemed to suggest it wasn't just a 12v battery problem. I'm on my 3rd 12v battery. Tess is starting to feel like my Mercedes. "Sure we'll look at it, $125 please." Looking at the bright side, I just returned yesterday from a 4 day drive through the northern-most part of Arizona. Just me and the Navajos. What would not have been good. But my trip up to Scottsdale on Saturday for a Model X Test Drive event is now in jeopardy, in more ways than one.
