The NHTSA have a continuing investigation into certain LGES high voltage batteries used in electric and hybrid vehicles. The investigation was prompted by the number of fire recalls on the electric and hybrid vehicles listed below. The purpose of this investigation is to find other companies that might have purchased the same or similar equipment from LG and to notify them if this defect has shown up in any vehicles they manufactured.
Recall No. 20V-107
Date: February 2020
Mercedes Benz USA notified NHTSA of a safety-related defect in one 2019 Smart ForTwo Electric Drive vehicle.
This vehicle received an LG Chem high voltage battery that may contain a defect allowing for an electrical arc, which can ignite inside the battery cells, increasing the risk of a fire.
Recall No. 20V-630
Date: October 2020
Hyundai Motor America notified NHTSA of a safety-related defect in certain 2019-2020 Kona Electric vehicles
. Note: The high-voltage battery system in the subject vehicles, supplied by LG, may have been produced with internal damage to certain cells of the lithium-ion battery increasing the risk of an electrical short circuit, which could result in a fire.
Recall No. 20V-701 & 21V-650
Date: November 2020
General Motors notified NHTSA of a safety defect in all 2017-2018 and certain 2019 Chevrolet Bolt EV vehicles.
These vehicles were built with high voltage batteries, produced by LG, that may contain latent cell-level manufacturing defects posing a risk of fire when charged to full, or nearly full, capacity. In August 2021, GM expanded this recall to include certain 2020-2022 Chevrolet Bolt EV and 2022 Chevrolet Bolt EUV vehicles
. GM stated, “the root cause of the failure is the simultaneous presence of two rare manufacturing defects in the same battery cell.”
Recall No. 21V-127
Date: March 2021
Hyundai notified NHTSA of a safety-related defect in certain 2019-2020 Kona Electric and 2020 Ioniq Electric
These vehicles are equipped with LG produced Lithium-ion battery cells where, if the Anode (Negative) tab is folded, the battery cell could allow the Lithium plating on the Anode tab to contact the Cathode resulting in an electrical short, thereby increasing the risk of a fire while parked, charging and/or driving.
Recall No. 22V-077
Date: February 2022
Chrysler notified NHTSA of a safety-related defect in certain 2017-2018 Pacifica Plug-In Hybrid Electric vehicles
These Pacifica vehicles contain hybrid battery packs produced by LG. FCA has not yet determined whether the battery packs were defective or the root cause of the fires.
Recall No. 22V-162
Date: March 2022
Volkswagen notified NHTSA of a safety-related defect in certain 2021 ID4 vehicles
The high voltage batteries used in the vehicles may contain insufficient soldering points and thus contain unreliable connections inside the high voltage battery. As a result of the unreliable connections, the vehicles may break down or stall while driving, leading to a crash.
