Hyundai is recalling over 145,000 Ioniq and Genesis vehicles due to a 12-volt battery charging issue that could cause the EVs to lose drive power and increase the risk of a crash.
NHTSA says the cause is the vehicles' Integrated Charging Control Unit (ICCU), which is likely to get damaged due to an internal electrical fault.
Upon failure of the ICCU, a series of driver warnings appear, and the vehicle activates a “fail-safe” driving mode that slowly reduces drive power over the course of 20 to 40 minutes.
Hyundai will instruct owners to take affected vehicles to dealerships to replace the ICCU and its associated fuse and install new software to prevent overvoltage that could damage the part again. Hyundai told NHTSA that as of November 2nd, “the improved ICCU software was implemented as a production running change” for the vehicles.
Affected models include 2022-2024 Ioniq 5, 2023-2025 Ioniq 6, 2023-2025 Genesis GV60, 2023-2025 Genesis GV70 (Electrified), and 2023-2024 Genesis G80. Hyundai will notify owners of affected vehicles via mail starting in January and will provide reimbursements for out-of-pocket expenses related to this recall.
These aren’t the first Hyundai EVs to get a widespread recall. In 2021, over 80,000 Kona EVs were recalled due to a fire risk caused by an LG battery defect after reports of a dozen battery fires.
Other electric vehicles have gone through similar recalls regarding power loss before, including the Porsche Taycan, Lucid Air, Ford Mustang Mach-E, and the now-defunct Fisker Ocean.
