NHTSA Complaint #11702325 — 2022 HYUNDAI IONIQ 5

On November 29 2025 my 2022 Hyundai Ioniq 5 with 49000 miles was warming up in the driveway. I heard a pop sound from the back seat like a soda can being opened (or a fuse blowing). Immediately afterwards warning lights appeared on the dash saying "Check Electrical System." The vehicle lost power to accelerate and could not be driven effectively. After a few moments, another error saying "Power is Limited" appeared. This could have happened on the roadway which would have been hazardous to myself and other drivers. The car is scheduled to be diagnosed next week by Simmons Rockwell Hyundai in Elmira, NY. These symptoms are similar to the hundreds of other reports of ICCU failures in this car and similar models. On Sept 10, 2025 the car was previously issued software updates to the ICCU software , which were required under NHTSA Recall Number 24V868000. If this problem is proven to be an ICCU failure, the experience with this car is an example of the 2025 software update failing to prevent the ICCU Failure. I request swift action from the NHTSA to compel Hyundai to implement a permanent fix for my vehicle and all other afflicted models in order to make Americas roadways safe again. Until then, everyone should be extra careful when driving behind a Hyundai Ioniq, 5 because it is at risk of dying and coming to a complete stop at any moment. Hyundai is a large corporation and has the resources and technology to fix this, but they have not done so, despite there being more than 300 complaints to the NHTSA about these cars at the time of this writing.
