GM to Replace All Battery Modules in Recalled Bolts
August 19, 2021—General Motors will begin replacing all lithium ion battery modules in nearly 69,000 recalled Chevrolet Bolt EVs in an effort to reduce the risk of the vehicles catching fire.
GM spokesman Dan Flores said on Tuesday the company has started mailing recall letters to affected owners, according to the Detroit Free Press. Flores said GM engineers and LG Chem experts found "the simultaneous presence of two rare manufacturing defects in the same battery cell" as the primary cause of fires in certain Bolt models and added full battery replacement would not be necessary.
"A battery pack is made up of many individual components including the case, some electronics, wiring, battery modules among other things. We will be replacing the five lithium ion battery modules within the battery pack," Flores said. "The battery pack case, wiring and other components are not defective and do not need replacing."
Repairs could begin as soon as the end of the month.
