This is an interesting problem... Perhaps your car thinks it is me?
Actually, with my careful perusal of this web site and direct experiments, there are different levels of resetting that you might not know about.
I am developing a hobby of resuscitating dead or misbehaving Teslas in my small sphere of influence and there seems to be three levels of severity of reboots. However I am not an engineer, just a user and and an enthusiast. The first level is the double scroll wheel reboot that seems to reboot the MCU and fixes small issues.
A more severe reboot is located under safety and security and forces the car to "turn off." This seems to have fixed persistent misbehavior that the scroll wheel reboot does not. I think this reboots the whole car. I just fixed a MS that would not drive for its owner today. (I hope this fixes the problem, gulp!)
The most deep reboot that seems to clear caches and misbehavior I learned from this forum is to reset the wheel size of the car. I have done this on my MX once or twice and after resetting from 20" to 22" wheels, forces the whole car to reboot and clear memory caches... and then I set the wheel size back to to correct size. That has fixed a few problems I have had.
Finally, you can pull the power cable off of the hot plug to the 12 volt battery (I have never had to do that) in the fuse box behind the plastic cover in front of the wipers for a few minutes, or manually disconnect the fireman's cable (also under the plastic cover) to get a reset and reboot.
