Consumer Description

My original eMMC failed and Tesla at first wanted to charge me to replace it. Then, online, I found out my car had the 8gb eMMC that Tesla was supposed to “voluntarily” replace. I told Tesla this and they agreed to replace it at no charge. The next day, my MCU failed. The car wouldn’t unlock, wake up, or connect to the Tesla App. The next day it woke up and drove fine. The following day, it wouldn’t wake up again. I had the car jumped and taken to Tesla. They now say the original MCU needs an “upgrade” and I have to pay about $3400 for it. From my understanding, the eMMC is part of the MCU. It seems the replaced eMMC won’t work with the original MCU. So-they voluntarily replaced a part that caused another part to fail. This seems like a scam rather than a fix.
