Hyundai Ioniq 5: Sudden Power Loss Investigated

Korean Auto Brand July Service Campaign

The National Highway Traffic Safety Administration (NHTSA) is presently examining reports of potential power failure while operating the 2022 Hyundai Ioniq 5. The NHTSA’s Office of Defects Investigation (ODI) declared that it has gotten 30 consumer grievances that allude to an obvious loss of power while driving in the car chosen for the title of 2022 World Car of the Year.

The Office of Defects Investigation (ODI) has reported that Hyundai Ioniq 5 owners have experienced a “loud popping noise” followed by a warning display on the dashboard and a sudden power loss. This has prompted the National Highway Traffic Safety Administration (NHTSA) to launch an investigation into the 39,559 Hyundai Ioniq 5 electric vehicles.

The NHTSA has launched multiple interviews as confirmation that the 2022 Hyundai Ioniq 5 has an energy issue. Pleasedly, at present there are no reports of connected crashes or traumas.

The ODI discovered, through Hyundai, a link between the power deficiency and the Ioniq 5’s Integrated Charging Control Unit (ICCU), a component intended for powering the EV and its low-voltage 12V battery. The initial research suggests that an excessive amount of current within the ICCU may harm the transistors in the EV’s Low Voltage DC-DC Converter (LDC).

Significantly, the LDC serves to transfigure electricity from the high energy battery into lower voltage (12V) in order to provide power to the transport.

Consequently, the malfunctioning of transistors brought about by an extent of surpassment of current leads to the incapability of refuelling the 12V battery of Ioniq 5.

Hyundai declared it will commence a service push in July to tackle the problem. Consequently, either software of the concerned cars will be modified or their Intentional Control and Communication Unit (ICCU) might be changed depending on requirement. Furthermore, they issued a proclamation saying:

“At NHTSA, we highly value our cooperative relationship and have been actively engaging in frequent, open, and transparent conversations about this topic.”

It is certainly not the first time Hyundai has experienced an issue with its EV battery. Back in 2021, the Korean carmaker announced a wide-spread recall for more than 82,000 EVs as multiple Hyundai Kona Electrics had combusted whilst plugged into the mains for a charge.
