Luckily my destination was San Francisco / Cupertino last night (meaning a short hop to Tesla Menlo Park once they're open) but I had a couple of problems last night with the trip. I charged in range mode, showing 244 miles of range. During my initial 112 m leg into downtown SF, a warning came on telling me my tire monitor needed service. No problem. (By the way, HOV stickers ROCK - saved me at least an hour.) The car was parked about 4 hours before driving another 40 miles to Cupertino. When I parked in Cupertino, ideal range was around 75. But when I started the car an hour later, I received the warning that 0 miles remained. I drove it about 5 miles over to a friend's house where it's been charging all night on 110v/12amp. It still shows 0 miles. It still shows it's charging successfully. I'll call Tesla before driving over to get confirmation on my assumption that I have plenty of range, even though 0 miles is showing. Has anyone else had this happen to them?
