“It is the ICCU (Integrated Charging Control Unit). The car lost power while I was going up a steep hill with a car behind me. The Hyundai dealership technician stated it is the ICCU (Integrated Charging Control Unit), and according to him, We have ordered a replacement ICCU and FUSE. No eta on special order parts. …”

NHTSA complaint #11709790, filed 2026-01

“I was driving at 60mph. I heard a sudden pop that felt like it came from behind me / under the car. While I glanced to see if I ran over something (I did not), the car suddenly felt like it was about to stall. It was slowing down quickly and dramatically. My safety was in danger as I quickly dropped speeds in heavy traffic on a freeway without warning. I was able to maintain control, and I turned my hazards on. …”

“The ICCU died and the fuse on my traction battery blew. Both had to be replaced. I realized I had the problem when I started my car and it showed Check Electric Vehicle System . When I tried driving it, I was limited to speeds below 45MPH, then eventually 25MPH, and eventually it would enter turtle mode and I could limp along at a couple MPH. I found the car would no longer charge the 12V accessory battery and it would no longer receive a charge from my home charger.”

“Accelerator stopped working on the highway. Dash displayed an electrical system warning and speed dropped to a crawl. The hazard came from being on an interstate at night and the closing speed for everyone behind us. Fortunately we were by an exit and could drive in the shoulder at 25 mph to it. Vehicle was towed to Stew Hansen Hyundai in Clive, IA. 12-volt battery, ICU and high-voltage fuse were replaced. My VIN did not appear in NHTSA recall lookup results for this issue.”

“I leased the 2025 Hyundai Ioniq 6 in April of 2025, in November of 2025 the car charging time started to increase when using L3 charging stations. The normal charging time would be 15 minutes for the battery to reach 80% capacity and an additional 30 minutes for the battery to reach full capacity. After November it took 20 to 30 minutes for the battery to reach 80% capacity. On January 2, 2026, I was charging the car at a L3 station and when charging was completed the car no longer worked. …”
