The National Highway Traffic Safety Administration is inspecting the 2022 Hyundai Ioniq 5 after 30 consumers complained that they had “a loss of motive power.”
The complaints caused the NHTSA’s Office of Defects Investigation to open an investigation on June 8 after consumers reported a “loud pop noise” before losing power.

“Many consumers report a loud pop noise followed by a warning displayed in their dashboard and immediately experience a loss of motive power that ranges from a reduction to a complete loss of motive power. ODI conducted several owner interviews confirming a range of loss of power and varying time intervals between the warning message and loss of power,” the NHTSA said in its filing.
The NHTSA has not reported any crashes, fires, injuries, or fatalities from the alleged problems with the electric vehicle, but it did say when it opened the investigation that it learned from Hyundai that the power failure was related to the integrated control charging unit, which powers the hybrid vehicle battery and the low-voltage 12V battery.
A spokesperson for Hyundai told the Washington Examiner it is fully cooperating with the agency’s investigation and that it would launch a campaign next month to update the software of the affected cars and, if necessary, replace their components.

“Hyundai is fully cooperating with NHTSA’s preliminary investigation (PE23-011) into a condition related to the Integrated Control Charging Unit (ICCU) in U.S. model year 2022 Hyundai Ioniq 5 vehicles. To address the concern, Hyundai is launching a service campaign in July that will update the affected vehicle’s software and replace the ICCU if necessary,” a spokesperson said in a statement.
“We value our cooperative relationship with NHTSA and have engaged in frequent, open and transparent dialogue with the agency on this topic,” the spokesperson added.
