Hybrid system on other Ioniq 5 years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2024, 2026.
What this problem usually is
These reports come from hybrid, plug-in and electric vehicle owners whose car put up a system warning and lost power, sometimes dropping into a reduced-power mode on the road. Others describe a car that won't charge, a high-voltage battery or inverter replacement, or a problem that turned out to be the ordinary 12-volt battery all along.
What got replaced
Owners who name the part that was replaced mention the charger or port (22 reports), the traction battery (7 reports) and the 12V battery (6 reports).
Recalls and investigations

Is this a known problem?
The manufacturer has sent NHTSA 2 service bulletins or notices for the 2023 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 overheats while charging causing it to stop charging. Charging port is hot to the touch. Seems like a fire hazard. This issue has gotten worse over the last few weeks.”

Should you keep driving it?
This page can't tell you that. 0 of 27 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
