First, I should have written down all the error messages when they occurred but I didn't so bear with me. I was leaving town and put the car into Storage Mode with the battery at probably about 50+ miles. I was gone 6 weeks. When I returned the battery was 23-25 miles and I wanted a Standard charge so I simply changed the VDO settings and pushed the start button. The charge port light went from blue to red and I got a couple of error messages - one was something like Request Could Not Be Processed and another one was something like Service Required. I tried several things like unplugging the charge cord, closing/opening the charge door, unplugging the 240 v charge cord from the wall and no luck. A day or so later I did the same thing and the car started charging - Yellow ring flashing fast and then over the next couple of hours slowed down - usual process. NOW, however, the VDO screens were on but the "data fields" were blank. I inserted the key and nothing - no start-up sequence. Would not engage reverse or drive. DEAD! The car was in a garage, not excessively hot or humid - just the same old situation for the last 6+ years. I called Tesla Torrance service about 9/20 and the earliest appointment is 10/6. Yesterday, just for the hell of it, I went out to the car, stuck in the key and PRESTO! CAR ALIVE. I topped off the Standard charge to 176 and with a little bit of pucker went for a 15 mile drive about 10pm. Everything appears fine. Needless to say I'm a little hesitant to drive the car - my confidence that I won't be stranded while driving or dead when I want to head home has been reduced. I need the "annual service" anyway so I'll keep the 10/6 appointment and mention the problem to the service mgr. but ... Any thoughts of what might have caused all this?
