Is this a known problem?
The manufacturer has sent NHTSA 2 service bulletins or notices for the 2022 Hyundai Ioniq 5 that deal with this problem. Newest first.
Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.
Certain IONIQ 5 (NE EV), IONIQ 6 (CE EV), and IONIQ 5 N (NE EV N) vehicles may have missing Inlet 5-Pin Combo DC insulation caps (DC pin caps) which may lead to damage to the charge port if not replaced.
This bulletin provides service information on how to inspect the charging port and if needed, replace any missing/damaged insulation cap(s) at the charging port on certain 2022-2023MY Ioniq 5 (NE1) and 2023MY (CE1) .
What owners wrote

“Charging port becomes exceedingly hot and vehicle stops charging. The charging end of my cable is extremely hot to the touch.”

“My car is unable to charge at the advertised 48A charge limit due to overheating of the charge port. Once I start charging, within 30 minutes to 2 hours the car will stop charging abruptly. It appears this is due to the AC Inlet port sensor reading 212F degrees when the issue occurs. The car is advertised as having 48A charging and if itâs not capable of this, Hyundai needs to resolve it.”

“Charging at home with a 240v level 2 charger overheats the car charging port causing a charge failure. This is a potential fire hazard.”
