NHTSA Complaint #11716579 — 2025 HYUNDAI IONIQ 5

What failed: On February, 6, 2026, I experienced a complete failure of my Ioniq 5's electrical system due to the ICCU failing. Heard a loud "pop" and eight seconds later it reported a warning to check the vehicle's electrical system and 24 seconds after the pop it then chimed repeatedly saying to pull over immediately and come to a complete stop. The vehicle is currently at a nearby My safety: Once I was able to hobble the car off the side of the road, it left me in a dangerous situation. The vehicle was such in a state that the hazard lights were not operational and I had no way of getting any heat. (It was 20F with a wind chill down to 14F.) It also happened in a bad part of town, meaning that I did not want to leave the vehicle unattended for a tow truck. This also occurred 60mi from home. Reproduced: The dealership it was towed to is not open until Monday, February 9, 2026 but the tow's rescue battery made the system run enough to report the Diagnostic Trouble Code of "P1A9096". Doing a quick search online for that shows a number of cases with the same problem. While waiting for the tow, I tried to start the car a number of times to no avail. Inspected: Not yet, see "Reproduced" section above. Any other signs/symptoms? Nothing until the "pop" itself. Once that happened, basically every warning icon showed up on the instrument cluster/screen.
