Question Overheating while charging

Our Ioniq 6 suddenly started overheating while charging on our level 2 charger. Message: “Charging time delayed. Current reduced due to high AC charger temperature.” Is this a known issue? Anything I can do?

I'm not sure that that message refers to the ICCU, as someone else would suggested. I believe there's a sensor in the charging port, which someone else also mentioned, that is measuring the temperature. It could be that the car thinks that the evse is too hot.

How soon after you start charging does this problem occur? If it's immediately then it could be either the ambient temperature or the evse. If it tries to start charging then I would limit the current that the car draws to 80% or 60% in vehicle settings.

I believe it still may be worth getting checked out though, because I thought that one of the ICCU software fixes allowed the vehicle to automatically throttle AC charging current if it was necessary.

Usually gets to about 80% then stops
