The National Highway Traffic Safety Administration (NHTSA) has initiated an investigation into the Hyundai IONIQ 5 electric SUVs following a surge in consumer complaints about power loss issues. The NHTSA’s Office of Defects Investigation (ODI) is focusing its attention on the 2022 model year of the Hyundai IONIQ 5 as it delves deeper into the matter.
Numerous drivers have reported a recurring pattern of events associated with the power loss problem. It begins with a sudden loud pop noise, followed by a warning message displayed on the vehicle’s dashboard, and ultimately leads to a complete or partial loss of motive power. The severity of the power loss varies, but it has raised concerns among IONIQ 5 owners.
Hyundai, in response to the investigation, has informed NHTSA investigators that the power loss issues are directly linked to the integrated control charging unit (ICCU), which is responsible for supplying power to the electric vehicle’s batteries. According to the preliminary review conducted by the ODI, it appears that the ICCU can sustain damage to its transistors when it receives an excessive amount of current. This damage subsequently impedes the charging process of the vehicle’s 12V battery.
In order to determine the scope and severity of the potential problem, the ODI has opened a Preliminary Evaluation. Throughout this evaluation phase, the agency will collect and analyze data from consumer complaints, while Hyundai will have the opportunity to present relevant materials and information.
In a statement made on Monday, Hyundai confirmed its full cooperation with the investigation and announced plans to launch a service campaign next month. This campaign will involve updating the software of affected vehicles and replacing the ICCU if necessary, aiming to rectify the power loss issues.
Despite the growing number of complaints, the ODI has not received any reports linking these power loss incidents to accidents or injuries. However, the situation warrants further investigation to address the potential risks associated with the power loss problem in the IONIQ 5.
The IONIQ 5 represents Hyundai’s first dedicated electric vehicle and is built on the Electric-Global Modular Platform (E-GMP). Priced at $41,450 and offering an EPA estimated range of up to 303 miles, the IONIQ 5 has garnered significant attention in the electric vehicle market. Hyundai has been striving to solidify its position as one of the top three global electric vehicle producers by 2030. As of May 31, 2023, the company has already sold over 10,500 IONIQ 5 models.
Once the evaluation is completed, the NHTSA will have two options: to close the investigation if no further action is deemed necessary or to proceed to the next phase. The current investigation encompasses a total of 39,559 IONIQ 5 models. As the situation develops, we will continue to provide updates on any new information and findings related to the investigation into the Hyundai IONIQ 5’s power loss issues.
