Hyundai has broadened the recall for its Ioniq 5, Ioniq 6, Genesis GV60, and Genesis Electrified series. If drivers overlook a set of warning signals, the affected electric vehicles (EVs) will transition to a fail-safe mode, leading to a complete loss of power. This recall adds to a previous announcement made in March 2024.
This week, Hyundai Motor America revealed the recall of 145,235 electric vehicles from its Ioniq and Genesis luxury brands, as reported by the NHTSA.
The issue arises from the Integrated Charging Control Unit (ICCU) potentially suffering heat damage, which inhibits the charging of the 12-volt battery responsible for low-voltage auxiliary systems. Such failures can trigger an open fuse, prompting the system to recognize a fault. Once a fault is detected, the vehicle shifts into a “fail-safe” mode that progressively reduces drive power until it is completely disabled.
This situation has been under Hyundai’s investigation since October 2022 and previously resulted in a recall on March 15, 2024, affecting 99,055 Hyundai and Genesis EVs. The current recall expands and replaces that earlier effort, identified as 24V-204.
The expanded recall necessitates that both newer models and older vehicles already remedied under the previous recall return to a Hyundai or Genesis service center for inspection, potential control unit replacement, and a software update.
The models included in the recall are:
In the event of this issue, drivers may experience a sequence of auditory and visual alerts on the instrument cluster. Following these warnings, the vehicle will enter “fail-safe” mode, which diminishes propulsion power from the motors over a period of up to 45 minutes. Critical functions such as braking and power steering will remain operational.
If the driver disregards the warnings and continues to operate the vehicle, all drive power will ultimately be terminated.
Earlier this year, Hyundai identified that overloading of the ICCU can be caused by either overcurrent or overvoltage at the conclusion of a DC fast-charging session or excessive thermal loading during operation.
While Hyundai has reported no injuries or accidents linked to this issue, they have noted 675 instances where the event has occurred.
In March, Kia also recalled the Kia EV6 due to the same problem. We will provide updates if Kia is included in this expanded recall.
Hyundai and Genesis owners should expect to receive notifications by mail as early as January 15, 2025, advising them to visit a Hyundai or Genesis dealer for the necessary fixes. Repairs will be covered under warranty, and reimbursement may be available for any “out-of-pocket expenses incurred to address the recall,” including costs for rental vehicles.
