Hyundai is recalling nearly 35,000 electrified vehicles Canada and over 145,000 in the United States due to concerns related to their Integrated Charging Control Unit (ICCU), a component critical to charging the 12-volt auxiliary battery.
The recall targets several models in Hyundai’s electrified lineup, including:
- Hyundai IONIQ 5 (2022–2024)
- Hyundai IONIQ 6 (2023–2025)
- Genesis GV60 (2023–2025)
- Genesis GV70 Electrified (2023–2025)
- Genesis G80 Electrified (2023–2024)
In total, 145,235 vehicles in the U.S. and 34,529 in Canada are impacted by the defect, which could lead to a loss of drive power if the 12-volt battery becomes unable to charge.
According to the recall information on the Transport Canada and National Highway Traffic Safety Administration (NHTSA) websites, the problem lies in the ICCU, which charges the 12-volt battery and powers the vehicle’s low-voltage systems. The ICCU may experience electrical load conditions that cause its internal metal-oxide semiconductor field-effect transistor (MOSFET) to fail. This failure can blow an associated fuse, preventing the 12-volt battery from charging.
When the ICCU detects a fault, the vehicle enters a fail-safe mode, gradually reducing motive power while maintaining critical systems like airbags, braking, and steering. However, if the vehicle continues to operate until the 12-volt battery is fully discharged, it could result in a total loss of propulsion, posing a safety risk.
While Hyundai has not reported any crashes, injuries, or fires linked to this issue, the risk of a complete loss of drive power increases the likelihood of accidents. Drivers may notice warning signs, including:
- Dashboard warning lights and chimes
- Warning messages on vehicle displays
- Reduced vehicle power or speed during operation
These warnings typically appear 20–40 minutes before drive power is lost, allowing some time to pull over safely.
Hyundai is instructing affected owners in Canada and the US to visit dealerships for a free inspection and repair. The remedy involves:
- Updating the ICCU software to include a “soft start” function that prevents overvoltage during battery charging.
- Inspecting and, if necessary, replacing the ICCU and its fuse.
Hyundai has assured that all repairs will be performed at no cost to owners, regardless of warranty status.
