- Hyundai has expanded the recall of the Ioniq 5, Ioniq 6, Genesis GV60, and Genesis Electrified models
- If the driver ignores a series of warnings, the affected EVs will enter a fail-safe mode where the car will lose power
- The recall builds on an earlier recall from March 2024
Hyundai Motor America has recalled 145,235 electric vehicles from its Ioniq electric and Genesis luxury brands, the NHTSA disclosed this week.
The Integrated Charging Control Unit (ICCU) can suffer heat damage that fails to charge the 12-volt battery that powers low-voltage auxiliary equipment. Such instances result in an open fuse and the system will detect a fault. Once the fault is detected, the vehicle enters a “fail-safe” mode that gradually dials back drive power until there is none whatsoever.
The condition has been under investigation by Hyundai since October 2022 and resulted in an earlier recall from March 15, 2024 totaling 99,055 Hyundai and Genesis EVs. This recall expands and replaces the earlier recall, which was classified as 24V-204.
The expanded recall includes those models already recalled and more recent models. All of the recalled models, including the ones already fixed, will need to go back to a Hyundai/Genesis dealer service center for inspection, possible replacement of the control unit, as well as a software update.
The recalled models are:
If it happens, the driver may notice a series of audible and visual warnings in the instrument cluster. Then the vehicle will enter into the “fail-safe” mode that reduces propulsion power from the motors over time, estimated to last up to 45 minutes. Other systems such as braking and power steering remain operable.
If the driver ignores the warnings and continues to drive, then all drive power will be cut.
Earlier this year, Hyundai attributed the cause of overloading the ICCU to overcurrent or overvoltage at the end of a DC fast-charging cycle, or from too much thermal loading when driving.
Though Hyundai knows of no injuries or crashes related to the incident, it has acknowledged 675 incidents of the event happening.
Last March, Kia also recalled the Kia EV6 for the same issue. We’ll update this report if Kia joins the recall population.
Hyundai and Genesis owners can expect notification by mail as early as Jan. 15, 2025, and they will be advised to bring their EVs into a Hyundai or Genesis dealer for the fix mentioned above. The repairs are covered by warranty and reimbursement may be provided for “out-of-pocket expenses incurred to obtain a remedy for the recall.” That may include rental car costs.
