The maps is on a separate card. However the main eMMC has many references to it. So there is a good chance it is eMMC related, since depending on what files get corrupted, different errors can occur. The list we have just outlines what people have identified so far. None of the MCU's I've seen have failed in any different way.Been consistent message since I think Thursday.
Air suspension has been unavailable a couple times though that might have been ice related.
On one of the power off reboots and restarts I got an error about "can not drive plugged in" when it was not.
Screen has been displaying fine, I stream music probably 70% of the time I drive and it had been pretty good occasionally a song will cut off and it will load another but not enough that that alone would be noteworthy.
FWIW the car is tracking position fine maps are moving behind the music/camera tabs.
Once we create the backup and check it, i'm pretty sure we will see a high level of corruption on one such as yours.
