mine have also failed today
no AP, TACC, sentry and at a guess all of the safety stuff that relies on it?
all cameras are black and in perpetual loading state
booked service
asked them to send full update file
it arrived and got stuck at 100%
asked for it to be sent again, car now refusing the update file and requires a hard reset which can only be done at a service centre
tried two button resets
full power down resets
and no trying deep sleep, app closed, no interaction with the car for a day
second time for me since a previous update a few months ago
starting to wear my patients tbh
