Consumer Description

Vehicle stopped charging and will not charge using a level 1 or level 2 charger. It will charge at a level 3 charger only. Took it to a Hyundai dealership and they did a software update and said it was fixed. Took it home and still would not charge. Took it to another Hyundai dealership and they said it was an ICCU issue they had been seeing and it would need to be replaced. I have read from many other Hyundai Ioniq 5 owners about the ICCU being a weak point in the car and having to have it replaced, some multiple times. When I tried to charge with my level 1 charger at home, it tripped the breaker, which is concerning. The message on the dash was simply, "check battery system".
