The affected models include a range of Hyundai and Genesis vehicles from different years, specifically targeting more than 145,000 units from the 2022 through 2024 Ioniq 5, the 2023 through 2025 Ioniq 6, GV60, GV70, and the 2023 and 2024 G80.

According to the National Highway Traffic Safety Administration (NHTSA), the recall is necessitated by an issue with the Integrated Charging Control Unit (ICCU). The faulty ICCU can become damaged and stop charging the 12-volt battery, which could lead to a complete loss of drive power. The agency has estimated that a total of 145,235 Hyundai and Genesis vehicles are impacted by this defect.

To address the issue, Hyundai dealers will inspect and, if necessary, replace the ICCU and its fuse at no cost to the vehicle owners. The NHTSA emphasized that even vehicles previously serviced for similar issues will require this new remedy to be completed.

Kia, partially owned by Hyundai, is also recalling almost 63,000 Kia EV6 models from 2022 through 2024, with approximately 1% estimated to contain the defect. The problem stems from a transistor in the charging control unit that can fail, halting the charge to the 12-volt battery. This can ultimately result in the vehicle losing motive power if the driver ignores warning signs and continues driving in a reduced power mode.

Similar to the Hyundai recall, Kia dealers will inspect and replace the malfunctioning control unit and its fuse if necessary. They will also update the vehicle's software. Owners who took part in a previous recall for the same issue will have to visit their dealer again for this latest remedy.

Vehicle owners affected by these recalls will be notified by letter in December and January.
