Please Note: This issues has been resolved via Tesla Service as of 3-16-2013...
After installing v4.3, my doors won't lock now (this has never happened before???) Earlier when it did this I called Tesla Customer Service, and they said to reboot the system (which solved it for an hour). Later, I walked out to my MS, and it was unlocked and my interior and door lights were on.
I notice that when I try and lock my doors with my fob, I hear the door handle motor, however, my door handles are not detracting, and remain unlocked.
Called Tesla Customer Service again, and they tried locking my doors remotely, and couldn't. I also couldn't do it via my iPhone with the Tesla App. It's like my MS now has a mind of it's own ;-0
The customer service rep said there wasn't anything else he could do from his end, so I will need to bring it in to my local service center for further evaluation.
Looks like I will have to ICE to work tomorrow, until I can get it into my service center :-(
Note to self: Don't download updates the day before work.
