LGES High Voltage Battery Failures

What NHTSA is examining

On April 1, 2022, the National Highway Traffic Safety Administration (NHTSA) opened an Equipment Query (EQ) to contact and obtain information from LG Energy Solutions (LGES), a supplier of high voltage batteries, and its purchasers that received the same or similar high voltage batteries as identified in recalls for Mercedes Benz 20V107, Hyundai 20V630, General Motors 20V701 and 21V650, Hyundai 21V127, Stellantis 22V077, and Volkswagen 22V162. The purpose of contacting these companies was to 1.) make the companies aware of the defects as described in the aforementioned recalls, 2.) have those companies determine the impact, if any, those defects have on the vehicles they manufactured, and 3.) ensure safety recalls are conducted as appropriate. On April 4, 2022, the Recall Management Division (RMD) issued an Information Request (IR) to LGES requesting: 1.) LGES provide a list of all customers that received the same or similar LGES high voltage batteries, 2.) the submission of a Part 573 Defect Information Report (DIR) to NHTSA or an explanation as to why LGES will not supply a report, and 3.) specific information related to the structure, materials and location of the manufacturing plant of the high voltage battery. On May 2, 2022, LGES responded to NHTSA’s IR, explaining that high voltage batteries contain three primary components: cells, modules, and packs. LGES stated that cells, modules, and packs are “manufactured in a separate process and customized to meet the…
