Well, I got the dread "12V error warning" earlier today as I got back into my car to return home from the grocery store. It cautioned me that my car may not restart. It took a few moments, but I was able to put the shift lever in drive, and I made it home.
I telephoned roadside assistance, and they told me that Seaside Service Center would be contacting me no later than Monday.
The service manager from Seaside called me about 45 minutes later. I inquired if the ranger could just come to Fresno when convenient next week to replace the 12V. He indicated that after he pulled my logs that there was a more serious (but not horrible) issue with "battery isolation." He apologized that he was not as familiar with the logs as the technicians are, but he felt that it had something to do with the battery heater.
(I told him that I thought something may be a little off, as the notification that I receive upon completion of charging would indicate that the battery was at 202RM, but when I would enter the car a few hours later, the rated miles were always down to around 192-194.) That seemed highly odd, as the lows here are not that terribly low (probably 45 degrees in the garage.)
So, the S85 will be picked up Wednesday morning and hauled to Monterey/Seaside.
Finally, what is interesting is that the return e*mail address refers to FresnoRangerService@teslamotors. However, apparently that address has not been created formally, as when I replied to the calendar appointment to thank them for prompt service, it was returned. (And yes, I just used the blue underlined link in the email that Tesla generated to me.)
Has anyone else experienced this sort of issue with the battery heater?
