Quick update, after a bit of research, have disabled “bluelink” and this has stopped the car charging suddenly. Now I will wait until 8.30pm, plug the car in and wait for 9.30 to see if charging starts, then a call to Hyundai. It does seem this is a “common” problem with “bluelink”, and not just with the Kona. Hopefully a solution will be forthcoming tomorrow.
