I wonder if that same "auto" setting is in the Kona.
On one forum, I think the U.K. one, someone mentioned he couldn't unlock his charging connector until pushing the door unlock function on the fob .
Yes, I got stuck on it as well, was very confusing as I never even locked the car. BTW, there is a mechanical release cable under the luggage cover, but how would I know, I was just test driving, well, with improvised DC charger detour. When this mode is disabled both car and charger refused handshake (error out), but cable ended up locked. I guess, DC charger was not happy to be locked or car was not happy it could not apply lock, but locked it anyways.
