General Motors Co.’s electric plug-in hybrid Chevrolet Volt is the subject of a U.S. safety probe after its lithium-ion batteries, supplied by LG Chem Ltd., caught fire in crash tests.
A Volt caught fire three weeks after a side-impact crash test May 12 while parked at a testing center in Wisconsin, leading regulators to conduct more tests. Volt battery packs were damaged in three more tests last week, causing two fires, the National Highway Traffic Safety Administration said yesterday in a statement on its website.
