I've been scanning Google generally and TMC in particular to see whether or not I'm the only one encountering this issue.
I had my MCU (AP 2.0) upgraded when I brought my MX in for the FSD computer upgrade in the middle of June.
Everything went fine, my settings were even largely preserved which was unexpectedly pleasant.
A week after the upgrade, I got a notification that the 12V battery needed replacement. This wasn't too surprising as my first 12V battery had to be replaced after 18 Months and this was almost exactly 18 months after that. When I asked the the mobile tech about it he told me that 18 months is pretty normal for these cars so.. yay warranty.
About three weeks later, the car was bricked. Dead. Unresponsive. I called Tesla roadside assistance and, when the tow truck arrived, the guy was able to just jump the car and things came back online and everything seemed normal. Shipped the car to the service center where they did nothing but sit on it for 5 days and then swapped out the battery for a new one.
Two weeks later, you guessed it, dead again. Same process as above. Car was in the shop 6 days this time. At the end of which I found they did ... no diagnostics and swapped the battery again.
5 days later, shockingly, dead again. This time car was picked up by a different service center who have been somewhat more diligent about keeping me apprised of what is going on. They *are* trying to reproduce the issue but it's taking a long, long time. The car has been in the shop for over 15 days now.
1) Has anybody experienced repeated 12V battery failures like this?
2) At what point is it reasonable to declare the car unfit for use and look to Tesla to replace it?
It's one thing to face the morning with concern that your car may or may not work when you're driving a beat up used car in high school, but I'm really not pleased that my rather pricey state-of-the-art vehicle is so vastly less dependable than... well.. ANY car I've owned before.
Thoughts for how I can proceed? Commiserations about facing the same issues? I'm feeling pretty down here.
Thanks!
