(Reuters) – Shares of Korean battery maker LG Chem slid to a nine-month low on Friday as investors digested reports linking fires in General Motors Co and Hyundai Motor Co vehicles to LG batteries from at least two Asia plants.
Documents filed by GM and Hyundai with the U.S. safety regulator show how the two automakers separately identified the same cause of battery fires in their newest electric vehicles, tracing them to similar manufacturing defects in battery cells made at at least two plants operated by a unit of LG Chem.
“Together with our client and partners, LG is actively working to ensure that the recall measures are carried out smoothly,” an LG spokesperson said on Friday. “The reserves and ratio of cost to the recall will be decided depending on the result of the joint investigation looking into the root cause, currently being held by GM, LG Electronics and LG Energy Solution.”
GM and Hyundai linked the fires to lithium-ion battery cells supplied by LG Energy Solution, an LG Chem subsidiary and one of the world’s largest battery manufacturers. The cells were produced at LG plants in South Korea and China.
In Korea, the decline in LG Chem shares reflected investors’ concerns about the multibillion-dollar cost of recalling the defective batteries and how that might affect the company’s relationships with GM, Hyundai and others.
LG provides similar EV battery cells to several vehicle manufacturers, including Ford Motor Co and Volkswagen AG. Ford and VW have not reported similar issues with the LG cells.
GM last week told the National Highway Traffic Safety Administration that experts from LG and GM on July 21 identified “two rare manufacturing defects in the same battery cell” as the root cause of the battery fires in the Chevrolet Bolt EV.
GM identified the defects as a torn anode tab and a folded separator, and said the defective cells were produced at LG’s plant in Ochang, Korea.
After the tenth Bolt fire, in Chandler, Arizona, GM said it had uncovered manufacturing defects in some cells “produced at LG manufacturing facilities beyond the Ochang plant.”
GM last week widened its recall of the Bolt to more than 140,000 vehicles to replace battery packs, at a cost now estimated at $1.8 billion. The automaker said it would seek reimbursement from LG – GM’s partner in the Ultium LLC battery joint venture in the United States.
In a statement on Friday, LG said its share of the recall cost “will be decided depending on the result of the joint investigation looking into the root cause.”
Hyundai said its investigators determined that a battery fire in a Kona EV – one of more than 15 such incidents in Korea, Europe and Canada – was caused by an internal short circuit in a battery cell. Hyundai traced the issue to a “folded anode tab.”
South Korea’s transport ministry said in February that it would recall Kona EVs with battery cells manufactured at LG’s China factory.
Hyundai said it would spend nearly $900 million to replace LG batteries in some 82,000 EVs worldwide, including more than 75,000 Kona EVs.
