Hyundai, Kia, Genesis EV Recall: Which Models Are Affected by the ICCU Power Loss Issue?

A significant recall affecting over 147,000 Hyundai, Kia, and Genesis electric vehicles has been issued due to a faulty Integrated Charging Control Unit (ICCU) that can lead to a complete loss of drive power, increasing crash risk. Owners of affected 2022-2024 models should expect notifications from manufacturers in late April and May 2024, with dealers performing inspections, replacements, and software updates free of charge.

What is the ICCU and What Risk Does It Pose?

The core of this recall is the Integrated Charging Control Unit (ICCU), a critical component responsible for managing the charging of the vehicle's 12-volt battery. In the affected EVs, this unit can become damaged over time. When it fails, it stops charging the 12-volt battery. While this battery is small compared to the high-voltage traction battery that powers the motor, it is essential for booting up the car's computers and electronic systems. A depleted 12-volt battery can result in a complete loss of drive power while the vehicle is in motion, a serious safety hazard that significantly increases the risk of a crash.

What Are the Warning Signs of a Failing ICCU?
