NHTSA Complaint #11713881 — 2024 HYUNDAI IONIQ 5

I heard a popping sound from behind driver seat when I started the car. A few minutes later a dash warning showed up "stop vehicle and check battery state" followed by a complete loss of power on the road within 3 miles of reduced power driving (I was trying to find a safe spot to turn out of 6 lane road). Vehicle had to be towed to dealer who states the Integrated Charge Control Unit ICCU is not working and needs to be replaced. (i suspect the popping sound was related to that - ?blown fuse). The Part is on back order and has to be ordered from Korea and during the weeks long wait they do not have a loaner care to provide. This ICCU issue had a recall with software fix in 2025 which was performed on my vehicle. Why is Hyundai not fixing this problem for good. And why are they not providing me a loaner car?
