WASHINGTON/SEOUL, April 5 (Reuters) - The U.S. National Highway Traffic Safety Administration (NHTSA) on Tuesday said it is opening a review to ensure all defective batteries produced by LG Energy Solution have been recalled by automakers.

The auto safety agency noted Mercedes-Benz, Chrysler-parent Stellantis, General Motors and Hyundai Motor have issued recalls since 2020 due to internal failures in high-voltage vehicle batteries that pose fire risks.

NHTSA said the equipment query covers 138,324 vehicles and will communicate with LG "and other companies that might have purchased the same or similar equipment from LG, notify them of this defect in any vehicles they manufactured, and to ensure thorough safety recalls are conducted where appropriate."

An LG Energy Solution spokesperson in a statement said the company understands the request by NHTSA is a follow-up procedure, adding, "LG Energy Solution will fully cooperate with the inquiry."

Among recalls cited by the agency were GM's recalls of its Chevrolet Bolt EV that prompted it to halt sales and production of new models in August.

In October, LG Chem Ltd, which owns LG Energy Solution, said it would take a charge of 620 billion won ($510 million) in its third-quarter results in connection with the GM Bolt recall.

NHTSA noted in February that Stellantis recalled 16,741 2017-2018 Pacifica Plug-In Hybrid Electric vehicles after the automaker said hybrid battery packs produced by LG were involved in 12 reports of vehicle fires.

The automaker said it "has not yet determined whether the battery packs were defective or the root cause of the fires."

NHTSA also cited a March 16 Volkswagen recall of 351 ID4 vehicles from the 2021 model year over batteries that may contain insufficient soldering points and potentially unreliable connections inside the high voltage battery. VW said vehicles may break down while driving, potentially leading to a crash. (Reporting by David Shepardson Editing by Bill Berkrot)
