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.

The car would no longer charge the 12V battery, and the EV battery would not charge. Hybrid Control Problem Detected at 3,160 miles. DTC P056216 https://plaincars.com/make/hyundai-ioniq-5-n https://plaincars.com/make/hyundai-ioniq-5-n#complaint-2160702 Sat, 27 Dec 2025 00:00:00 GMT 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. https://plaincars.com/make/hyundai-ioniq-5-n https://plaincars.com/make/hyundai-ioniq-5-n#complaint-2150404 Thu, 20 Nov 2025 00:00:00 GMT The contact owns a 2025 Hyundai Ioniq 5 N.
