South Korean multinational conglomerate Hyundai Motor Group has announced a substantial recall of more than 147,000 electric vehicles (EVs) in the United States. The massive recall of EVs is attributed to concerns regarding potentially damaged charging units. This recall mirrors a similar action in the automobile giant’s home market of South Korea, where nearly 170,000 Hyundai and Kia-branded EVs got impacted. In fact, the recall in South Korea sparked apprehensions regarding potential recalls in additional markets.

The automotive giant’s most recent recall in the U.S. encompasses a range of electric models, including the Hyundai IONIQ 5 and Hyundai IONIQ 6, along with the Genesis GV60, Genesis GV70, and Electrified GV80 e-SUV. The Kia brand is also recalling 56,016 units of the EV6 models in Korea. The issue that prompted the company to issue the recall revolves around a software glitch identified within the Integrated Charging Control Unit (ICCU), which has the potential to impact the vehicles’ battery power. This software glitch may lead to charging issues and, and in severe cases, it could result in a loss of power while the vehicle is in operation.

An investigation by the U.S. National Highway Traffic Safety Association (NHTSA) was commenced in June 2023 following reports of ICCU power loss in Hyundai IONIQ 5 EVs built between 2022 and 2023. Kia’s EV6 was also under scrutiny due to similar complaints. After thorough investigation, the NHTSA officially declared the recall of 147,110 EVs (including 98,878 Hyundai units and 48,232 Kia units) in the U.S.

As part of the recall process, dealerships will conduct inspections on the ICCU of affected EVs and replace the unit, if necessary, free of cost. Additionally, owners of the affected EVs will receive an ICCU software update at the dealerships. Notification letters containing details are expected to be dispatched to owners on May 14, 2024. Hyundai has assured customers that the updated ICCU software will effectively trim down thermal loading and lower peak voltage during operation, thereby mitigating the risk of ICCU damage.
