A/C failure on other Ioniq 5 years
No other Ioniq 5 model year has enough reports of A/C failure for a sheet of its own. See every Ioniq 5 year.
What this problem usually is
Most A/C complaints start the same way: the fan still blows, but the air coming out of the vents is warm or only a little cool. Some owners get cold air that fades after a while, and others hear a noise from the compressor before it quits. It's rarely a safety problem on its own, which is also why it seldom gets a recall.
What got replaced
Few of these reports name the part that was replaced.

What owners wrote
“The ICCU has failed for the 2nd time in a year requiring lengthy repairs. The car cannot be driven with a faulty ICCU. The ICCU is responsible for converting AC power to DC for and stepping it up to 800 volts to charge the primary battery. It is also responsible for keeping the secondary 12 volt battery charged.”

“The Dealer states my ICCU has failed and will be replaced. My vehicle could no longer charge on AC power (level 1 or level 2), and eventually had to be taken to the dealer because it could not be charged at home any longer due to the ICCU failing.”

“Unable to do AC charging due to faulty ICCU. A failing ICCU is dangerous to drive as the car may lose all of its power”
Filed Jan 29, 2026
“Plugged the car into an L2 AC charger like I have for nearly 2 years, the car tripped a breaker in my electrical panel and after restoring power to the charger, the car would no longer initiate a charge on L2 power. Confirmed this by attempting to charge at a public L2 charger, same result. Took the car to Hyundai and they confirmed the ICCU needs to be replaced and it's a wait of up to 8 weeks.”
