I have had both issues happen and another similar one. One with AP completely broken from the start of the drive, which did not get fixed even with reboot. The only thing that fixed it was pressing shutdown in the service menu and letting the car sit for 20 minutes. The other issue with autopilot quitting in the middle of the drive happened 4 times so far.. looks like a crash of the AP NN... very annoying. Another issue on this firmware that I have had happen twice is AP all of the sudden without prior warning detects that my hands have not been on the wheel for over a minute and starts slowing down, saying it will not be available for the rest of the drive.
