@lcamtuf this is abnormal. Teslas are not a PS3. You can choose to not install updates. I did a search on this error and it seems a few people encountered it when their cars failed to finish an update and were left in some weird state that required service. https://teslamotorsclub.com/tmc/threads/software-update-required-contact-tesla-service.231570/
@lcamtuf but obviously it’s a sucky situation. And even if inaccurate, the problem as described would be funny in a horror film.
