I am filing this complaint to report a serious safety defect involving my 2022 Hyundai Ioniq 5. The vehicle experienced a sudden failure of the Integrated Charging Control Unit (ICCU), which caused the car to completely shut down and lose power while in motion. My family member, who was driving at the time, stated that the car lost power and shut off without warning on the road, creating an extremely dangerous situation. Thankfully, they were able to pull over without incident, but this type of malfunction could easily result in a collision, injury, or worse. I later discovered that this issue is part of a widespread ICCU failure affecting Hyundai Ioniq 5 and other Hyundai/Kia EVs. My vehicle has been at the dealership for over a month, and Hyundai has informed me that the part required to repair the vehicle is backordered for 2â’3 months, leaving me without my primary mode of transportation. This issue is not only a reliability concern but a serious safety hazard that warrants immediate investigation and intervention. A vehicle that completely loses power while driving is unacceptable, especially for a relatively new vehicle under warranty. I urge the NHTSA to investigate the ICCU failures in Hyundai Ioniq 5 vehicles and determine whether a broader mandatory recall is needed due to the loss of motive power and serious safety risk. Many owners are affected, and delays in repair parts are putting consumers in unsafe situations.
