US highway safety agency reports power problems in 2022 Hyundai Ioniq 5 SUVs

DETROIT (AP) – Multiple American owners of Hyundai’s popular Ioniq 5 electric sports utility vehicle (SUV) have complained of completely or partially losing propulsive power, many after hearing a loud popping noise, the United States (US) National Highway Traffic Safety Administration (NHTSA) said on Saturday.

Hyundai said it would offer a software update beginning next month and replace affected components if necessary.

The NHTSA said in a notice posted online that it received 30 complaints about the problem in 2022 models, of which it estimated 39,500 were on US highways. The Office of Defects Investigation at the NHTSA has opened a preliminary investigation and said Hyundai indicated in an initial review that a power surge was damaging transistors, preventing vehicles’ 12-volt battery from recharging.

Hyundai spokesperson Ira Gabriel said the company was fully cooperating with the investigation and was launching a service campaign in July to update affected vehicles’ software and, if necessary, replace the component involved. It’s called an Integrated Control Charging Unit.

Technical problems accompanying automakers’ growing global rollout of electric vehicles to fight climate change have included battery recalls because of the potential for fires.

Last month, Jaguar recalled more than 6,000 I-Pace electric SUVs in the US due to the risk of the high-voltage battery catching fire.

General Motors, Mercedes-Benz, Hyundai, Stellantis and Volkswagen have also issued recalls since February of 2020, most due to internal battery failures that can increase the risk of fires.

The US National Transportation Safety Board also investigated a series of fires in Tesla vehicles and said the high-voltage lithium-ion batteries pose safety risks to first responders after crashes.

Many governments are counting on electric vehicles to replace gasoline-burning vehicles that emit greenhouse gases that cause global warming.
