A good news update. On my way home last night I also started to get a emergency braking is disabled notice so when I got home I decided to reboot the screen to see if that might help. This morning when I got in my car, the gremlins seemed to go away. No more error messages! I had a 100 mile round trip today and 1/2 way through the cameras seemed to finish calibrating and autopilot started working for the return part of the trip.
The reboot (and may some other goodness I don’t know about) seemed to do the trick and my last few hours with my new Model 3 were flawless (except for a finicky phone key which seems to be par for everybody and easily solved using the key card).
No return trip to the SC! Hopefully others will overcome early hiccups easily too and as production increases hiccups will diminish as well.
It was a roughest first 6 days of the 4 Tesla’s i’ve owned but now all good
