Time for some more testing:
The car is charging at my workshop. I turned off WiFi before attempting to charge to make sure there was no impact from that connection. Time is within allowable charge timer window for charging at home so charge timers should have no impact even if it not set for HOME only. Doors were closed and locked. I initiated charge by plugging in EVSE cable and charge started normally. I went out to do some testing after about 15 minutes. Unlocking doors had no impact on charging; opening right front door had no impact; charging stopped when I closed the door.
I then turned all charge timers OFF in the settings menus on the dashboard in front of the steering wheel. I turned off car, exited driver door, closed door, and locked car before initiating another charge session. I let the car charge for a few minutes before testing again. I then unlocked car, opened front passenger door, closed door, and locked car without charge being interrupted. I tried several times, opening all doors and hatch before closing and locking. I waited a few minutes and tried again. I have been unable to cause charging to stop since disabling the charge timers.
Therefore, it appears there are problems with the charge timer or navigation system software (or problems with communication between modules).
