This seems to be a common problem. My Ioniq 5 will not DC fast charge and yesterday my dealer confirmed it was faulty with the following:
"Carried out investigation into DC charging fault. Appears vehicle thinks charging overheating so shuts down. Will require master technician diagnosis for a few days".
A friend of a friend with a Kia EV6 (basically same car with a different skin) had the same problem. I am in UK, but any suggestion above that vehicle does not have fast charging in some markets seems unlikely. In fact Ioniq 5 is supposed to have faster charging (350kW, if you can find a charger that good!) than most anything else around. I now have to book it in again and will update once diagnosis complete.
