The high-voltage traction battery on my 2025 Hyundai Ioniq 5 Limited RWD failed unexpectedly around [redacted], when the vehicle had approximately 1,250 miles on it and was just over 3 months old. The car had been parked in my driveway with about 80% charge while I was away for several days. When I attempted to drive it, the vehicle would not shift out of neutral. No warning lamps or error messages were displayed before the failure. The vehicle was towed to Van Hyundai in Carrollton, TX on April 3. While loading it onto the tow truck, the 12V battery completely died, disabling the electronic parking brake and preventing the vehicle from being safely secured. After an extended wait, a Hyundai field service technician diagnosed the failure as a fault in the traction battery, requiring a complete replacement. I was told the part is currently unavailable and has no estimated arrival time. …
I was driving to work on the morning of Nov. 12th, 2025 in East Greenwich RI. The car had been fully charged on my home Level 2 charger the night before. It was a chilly morning so I turned on the heated driver seat and steering wheel. Less than a mile from my house, and without any warning or prior issues, I heard a loud pop from underneath the vehicle. Immediately the car displayed an error on the dash reporting electrical system issues. The car still seemed driveable so I began to drive back home, noting that the car wouldn't exceed ~30 mph, but before I went very far at all the error changed to "Stop vehicle and check power supply." I pulled the car over on a side road and called for a tow to the nearest Hyundai service center in North Kingstown, RI. The next day the Hyundai service center reported that their diagnostics revealed that the ICCU had failed. …

The ICCU (Integrated Charge Control Unit) failed. Fortunately I was in a parking lot at the time, as the vehicle limited its top speed to around 25 mph. Had the failure occurred on a highway it could have caused a collision. While this is a 2025 model year Ioniq 5, the ICCU hardware (part 36400-1XAA0) remains unchanged across all Hyundai/Kia/Gensis vehicles sharing the eGMP platform. NHTSA previously issued recall 24V-868 intended to address such ICCU failures. While the modified software is included from the factory in the 2025 model year Ioniq 5, it appears that the 24V-868 recall is not a complete fix. Indeed, ICCU failure continues to be one of the most commonly reported owner issues, both for vehicles which have already had the "fix" from recall 24V-868 and for newer vehicles outside of the recall's scope. …
On the afternoon of Saturday, December 12th 2025 I was preparing my car for a trip an hour north and back to drop my daughter off with her grandmother. I was charging my car with my Level 2 charger and preheating my car. Upon leaving for the trip, within a half mile I heard a loud popping sound coming from the rear of the vehicle and immediately had a warning on the vehicle stating "Stop Vehicle and Check Power Supply". The vehicle soon started to lose drive power, and I had to perform a U-turn and then parked at the nearby Quaill Volunteer Fire Department to perform a basic safety check. Knowing that I probably had the Hyundai Ioniq 5 ICCU issue, I knew that my car would soon have no power so I waited for an opportune time to leave the fire station to coast back to my house. After arriving home, I contacted Hyundai Roadside Assistance and my car was soon towed away. …
