The Hyundai Motor Group has initiated a substantial recall encompassing multiple electric vehicles under its three brands. Initially confined to the South Korean market, this recall aims to address an issue associated with the integrated charging control unit (ICCU).
The affected electric vehicles are those built on the E-GMP platform, including the Hyundai Ioniq 5 and Ioniq 6, the Genesis GV60, GV70, and G80 EVs, as well as the Kia EV6. A total of 169,932 vehicles in South Korea are slated for repair due to potential defects in their ICCUs, which could result in power loss while driving.
This recall marks the largest single recall of vehicles utilizing the electric-only E-GMP platform since its introduction in 2021, as reported by Business Korea. However, if Hyundai decides to extend the recall to other markets, it may need to address an additional 500,000 vehicles.
There are indications suggesting such an expansion is likely. The National Highway Traffic Safety Administration (NHTSA) commenced an investigation into the ICCUs of these vehicles in June 2023. According to its preliminary findings, over-current incidents in the ICCU can lead to transistor damage, hindering the recharging of the 12V battery.
NHTSA has received 30 complaints regarding this issue in the U.S. Owners have reported hearing a loud popping noise followed by a dashboard warning message. While some experienced a reduction in power, others faced complete power loss.
Both Hyundai and Kia have been aware of this problem for some time and have offered free repairs to affected owners since last year, as detailed by Business Korea. However, in light of continued reports of power losses, the decision to initiate a recall has been made.
To address the issue, the Hyundai group intends to implement a software update in all affected vehicles. Additionally, where necessary, the ICCU will be replaced entirely.
Hyundai has encountered significant EV recall incidents before. In 2021, it prematurely terminated the production of the first-generation Kona EV in South Korea following a global recall of approximately 100,000 vehicles. However, in that instance, the issue prompting the recall, and tarnishing the vehicle's reputation, was an elevated fire risk. There is no indication that the ICCU issue could lead to a similar outcome.
