Nearly 40,000 Hyundai Ioniq 5 EVs under investigation over reports of power loss while driving

NHTSA is investigating nearly 40,000 Hyundai Ioniq 5 electric vehicles over reports of power loss while driving tied to a battery charging issue.
The failure is related to the Integrated Charging Control Unit (ICCU) responsible for powering both the main electric vehicle and low-voltage 12-volt batteries.
Hyundai is launching a service campaign in July that will update impacted vehicles' software and replace the ICCU if necessary.
NHTSA conducted several owner interviews confirming a range of loss of power and varying time intervals between the warning message and power loss but did not report any crashes or injuries tied to the issue.
One complaint reported a driver traveling 75 miles (120 km) per hour on a highway using advanced highway assist and "the car became completely unresponsive."
