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

According to the U.S. National Highway Traffic Safety Administration (NHTSA), the issue stems from the Integrated Charging Control Unit (ICCU), which may be damaged by an internal electrical fault.

A failed ICCU triggers multiple warnings and causes the vehicle to enter a “fail-safe” mode, gradually reducing drive power over 20 to 40 minutes.

Starting in January 2024, owners will be contacted by mail and instructed to visit dealerships to replace the ICCU and its fuse. The company will also update the software to prevent overvoltage damage. Hyundai has committed to reimbursing owners for any costs incurred for related repairs before the recall.

This recall follows Hyundai’s 2021 recall of over 80,000 Kona EVs due to fire risks linked to LG-manufactured batteries. Other automakers have faced similar issues: Porsche Taycan, Ford Mustang Mach-E, Lucid Air, and Fisker Ocean have all been recalled for power loss or related defects.
