They’re replacing the chip (actually the daughterboard that hold the chip) with a much larger chip (32GB vs 8GB) and allocating half the chip for wear leveling.

This is the same fix a southern Cal company has been performing for a few years, at car owner’s cost.
They are not doing much in the way of preventive replacement, and their “predictive failure” notification is BS afaict. Maybe it’s new, but I’ve not yet seen it when my MCU starts acting up.
It’s currently a $500 non-warranty service, but they won’t do it until the chip fails.
Ask me how I know.
Edit: mem sizes

If they are using eMMC, it should be trivial to just query the controller about the flash health which should be a pretty accurate indication of when it's going to fail.
- zaroth 6y agoThe predictive notification is new as of 2020.40.9.2, which was released on November 24, 2020 after they extended the warranty. Just because it was release on 11/24 doesn’t mean all cars got it that day. Figure it can take a little while depending on how they roll these releases out to the fleet. https://tesletter.com/2020-40-9-2-update-emmc-failure/ https://tesletter.com/2020-40-9-2-update-emmc-failure/
