DETROIT: General Motors Co is taking a more direct role with South Korea’s LG Corp, its longtime electric vehicle (EV) partner, in tracking down and fixing problems linked to battery fires in Chevrolet Bolts that threaten the strategic plans of both companies.

At an investor conference on Friday, GM chief financial officer Paul Jacobson said LG is working with GM engineers to “clean up the manufacturing process” at LG battery plants and implement some “GM quality metrics.”
