I've run into what seems to be a known issue -- around 4 years after getting my Model S, the MCU now has to be replaced due to the burned out eMMC (flash memory) - caused by high volume writes (by syslog in the Linux subsystem). And since this chip is soldered to the motherboard, Tesla will charge between $2200 and $5000 for a new MCU. I was personally charged $3200.
I'm actually surprised, after reading all the forum threads describing this particular issue, that nobody has thought about suing Tesla for sabotage. Clearly, they know where the problem is coming from and obviously, they know how to resolve it, but it seems that charging owners that have no warranty anymore (coincidence?) is a good way for them to have a steady cash flow.
Let me know if you could share your own experience with the MCU replacement on your car.
And once I gather all the documentation and hopefully, signatures, I'm going to book some time with my lawyer.
