Software update bricked my car

[BigNick]

It sounds like the update was one write too many to the eMMC in the MCU, maybe?
Flash has a finite life span, and from what I understand older versions of the Tesla software generated a ton of log files. I don't think current versions are so write-heavy.

What’s the cost of the replacement MCU on that era of S? Maybe I should start saving

I had a similar issue, update caused a complete systems meltdown, just needed a system rebuild at the Service Centre and all is golden again.

Similar issue. Paid $1,500 for the new MCU(?) 2.5 months ago. The most recent update appears to have completely fried/bricked both batteries. $12,000 to fix, and I can't imagine they're going to offer any guarantees that it won't happen again.

I don't see how a software update can reasonably be blamed for causing a high voltage battery to fail...

Same thing has happened to me. 4 software updates in 5 months and the car has a "stroke" each time. "Stroke" = no AC, trunk won't open, passenger side windows and doors won't work). 2021 Model S LR. Do I have a Lemon?

Try doing a hard reboot after every update. That may fix your stroke.
