Over 30 US Ioniq 5 Drivers Raise Defects... Authorities Conduct Investigation

Road Traffic Safety Bureau Confirms Overcurrent Issue

In the United States, drivers of the Hyundai Ioniq 5 have reported sudden power loss while operating their vehicles, raising concerns about potential defects and prompting authorities to launch an investigation.

According to the U.S. National Highway Traffic Safety Administration (NHTSA) on the 17th (local time), a total of about 30 consumer complaints have been received regarding power loss incidents in the 2022 model year Hyundai Ioniq 5 vehicles.

Consumers reported experiencing a loud "pop" noise followed by warning indicators appearing on the dashboard, after which the vehicle's power was either completely lost or partially reduced.

Preliminary review results from NHTSA's Office of Defects Investigation (ODI) confirmed that the issue is related to the Integrated Control Charging Unit (ICCU), which supplies power to both the hybrid vehicle (HV) battery and the low-voltage (LV) 12V battery.

NHTSA explained that an overcurrent within the ICCU can cause damage to the transistor (FET) in the LDC (DC-DC converter), which in turn makes it impossible to recharge the 12V battery.

A preliminary evaluation will be initiated for the Ioniq 5 to investigate the potential safety-related issue.
