Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I have experienced two high voltage battery failures both requiring hv battery replacement. The first occurred around 6000 miles and the second occurred around 13,000 miles. I also had several dead 12v battery episodes where the card would be dead; even when plugged into the home charger overnight. I had to replace the 12v battery at 12000 miles.”
NHTSA complaint #11716115, filed 2026-02“What happened to me is a common problem with these models. I had an issue with the 12 V battery not being charged by the main battery as it should be. This led to a blowing of the main fuse which took out the ICCU unit. This seems to be fairly prevalent from what I can tell from online forums, and there needs to be a recall from Hyundai.”
NHTSA complaint #11707241, filed 2025-12“Integrated Charging Control Unit (ICCU) failed while driving. Heard a pop from below the rear seats. Check vehicle electrical system message popped up initially, then changed to Stop vehicle and check power supply Vehicle could not exceed 20mph directly after failure, then lost all driving power just as I pulled the vehicle off the road. If I hadn't found a place to pull over in time, the car would have stopped in the middle of the road putting my safety and the safety of others at risk. Dealer inspected and took over a month to replace ICCU and 12v battery.”
NHTSA complaint #11720305, filed 2026-02“While driving home, I experienced a sudden and complete power system failure in my Hyundai Ioniq 5 N. The failure occurred shortly after starting the drive, and was preceded by a faint pop sound. Within moments, the dashboard displayed the following critical warnings: Red 12V battery icon Red warning: Stop vehicle and check power supply Turtle icon (indicating limp mode / low power) Brake warning light ⚠️ The vehicle immediately entered limp mode, then fully lost power within approximately 3 minutes. I was able to safely pull into a nearby parking space before total shutdown and loss of power. …”
