2025 Hyundai Ioniq 6 Complaints

The windshield cracked from using the defroster to defrost the windshield. On a cold morning.

On April 10,2026 I heard a pop while driving and a check electrical system light came on, my vehicle lost power while driving. This appears to be a common problem with ioniq5 and 6 going back years. Also failure in their ICCU and 12 volt batteries.A veh. Losing power unexpectedly could lead to a collision, injury or worse.my Ioniq 6 was recently serviced and only has 14,794 miles.I respectfully urge the national highway traffic safety administration to: 1.continue and expand investigation into electrical system failures in the Hyundai ioniq 6 and 5. Also 2. Ensure that affected vehicles are properly repaired with permanent solutions or the company should have to buy back the unsafe defective vehicles. Also 3. Require clearer and more immediate warnings to drivers regarding the risk of sudden power loss. Drivers should not have to keep experiencing this safety risk, after all these years of it being reported.

"While traveling in fast-moving traffic, my 2025 Hyundai IONIQ 6 suffered a catastrophic electrical system failure and an immediate loss of motive power. The vehicle instantly entered a 'limp mode' and dropped to a maximum speed of 11 mph, creating a life-threatening hazard for myself and surrounding drivers. There were no warning lamps or symptoms prior to this sudden failure. The vehicle was towed to a certified Hyundai dealer (Ricart Hyundai), where a diagnostic scan confirmed a failure of the Integrated Charging Control Unit (ICCU) with error code DTC P1A9096. This failure is directly related to the known issues in Recall 257. The dealer has confirmed that the replacement ICCU is currently on indefinite backorder with no estimated time of arrival (ETA). The vehicle and failed component are currently at the dealership and available for inspection upon request."

On the evening of February 11, 2026, my 2025 Hyundai Ioniq 6 SEL experienced a complete ICCU failure while I was traveling with my minor son. The vehicle became fully inoperable and left us stranded on the side of the road at night, in the middle of a winter storm. I was forced to call for a tow truck, wait in dangerous conditions, and arrange emergency transport for myself and my child. The vehicle was towed to Visions Hyundai of Henrietta, located in Rochester, New York. That was over three weeks ago. As of the date of my complaint, my vehicle remains at the dealership. I have been told that the replacement ICCU part is on indefinite backorder, with no estimated delivery date provided. I am left making full monthly payments on a vehicle I cannot drive.
