Hyundai is recalling more than 145,000 Ioniq and Genesis electric vehicles (EVs) due to a fault in the 12-volt battery charging system that could result in a loss of drive power, increasing the risk of accidents.

The issue lies in the vehicles' Integrated Charging Control Unit (ICCU), which is likely to be damaged from an internal electrical fault, according to the U.S. National Highway Traffic Safety Administration (NHTSA). If the ICCU fails, drivers are alerted with multiple warnings as the vehicle transitions into a "fail-safe" mode that gradually reduces drive power over 20 to 40 minutes.

Owners of affected vehicles will be instructed to visit dealerships to replace the ICCU and its fuse while receiving updated software designed to prevent future overvoltage damage.

2022–2024 Ioniq 5, 2023–2025 Ioniq 6, 2023–2025 Genesis GV60, 2023–2025 Genesis GV70 (Electrified), and 2023–2024 Genesis G80 are among the models that are affected. The company plans to notify owners by mail starting in January 2024 and will reimburse costs incurred by owners for related repairs prior to the recall.

Similar recalls over power loss or related defects have affected other EVs, including Porsche Taycan, Ford Mustang Mach-E, Lucid Air, and Fisker Ocean.
