Hyundai, Kia, and Genesis are recalling nearly 150,000 EVs in the U.S. due to an electronics issue that could lead to 12-volt batteries losing charge while driving. This recall affects a range of models from Hyundai and Genesis, including the Ioniq 5, Ioniq 6, GV60, Electrified GV70, and Electrified GV80, as well as the Kia EV6 electric crossovers. The fault lies with the Integrated Charging Control Unit (ICCU), which can become damaged and stop charging the 12-volt battery, resulting in a loss of drive power.
## Recalling Nearly 150,000 EVs in the U.S.
The recall includes 98,878 Hyundai and Genesis EVs from model years 2023 and 2024, as well as 48,232 Kia EV6 electric crossovers from model years 2022 to 2024, totaling 147,110 affected vehicles. This follows a similar recall in South Korea earlier this month for the same issue. The ICCU can be damaged under various conditions, leading to warnings to the driver and a reduction in drive power.
## Steps Taken for Inspection and Replacement
Owners of the affected vehicles will be contacted by the brands to bring their cars to dealerships for inspection and, if necessary, replacement of the ICCU and its fuse free of charge. Additionally, updated software will be installed to lower thermal loading and peak voltage and alter the water pump operation. Despite advancements like 800-volt charging on the E-GMP platform used by these models, the absence of 48-volt electronics is a notable oversight.
## Slow Transition away from 12-Volt Systems
Automakers have been slow to move away from 12-volt electrical systems in new vehicles, with Tesla’s Cybertruck being one of the few models with 48-volt hardware. Despite proposals for vehicle-wide upgrades to 48 volts for mild-hybrid systems, Hyundai has not yet incorporated this technology in its EVs. While some hybrids have seen a shift away from traditional lead-acid 12-volt batteries, this innovation has not extended to Hyundai’s electric vehicles.
In conclusion, the recall of nearly 150,000 EVs in the U.S. due to an electronics issue highlights the importance of addressing potential faults in the charging system of electric vehicles to ensure safety on the road. By implementing inspection, replacement, and software updates, automakers can rectify these issues and provide peace of mind to EV owners. Further advancements in technology, such as transitioning to 48-volt systems, can help prevent similar incidents in the future and improve the overall performance of electric vehicles.
