LGES High Voltage Automobile Battery Fire Investigation

Posted on by

Automotive Defect Investigation

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.
Note: 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.
Note: 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 vehicles .
Note: 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.
Note: 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.
Note: 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.

A Dangerous Problem Worth Repeating
“Fire Warning For Chrysler Pacifica PHEV”

Posted on by

Chrysler recommends that owners of select model year 2017-2018 Pacifica plug-in hybrid electric vehicles park their vehicles outdoors and away from other vehicles or structures due to a risk of fire, even if the vehicle is turned off. Owners are advised to NOT charge their vehicles and continue to park outside until a remedy is identified.

In August 2021, Chrysler Technical Safety and Regulatory Compliance Organization opened an investigation into a reported trend of fires in certain Chrysler Pacifica PHEVs. Since August 2021, there have been five customer records and twelve field reports relating to this issue. The potentially affected vehicles include 2017-2018 Chrysler Pacifica PHEVs manufactured between August 12, 2016, when production of Chrysler Pacifica PHEVs began, and ended on August 7, 2018, when the 2018 model year production ended. Chrysler will conduct a voluntary safety recall on all affected vehicles.

Although the automaker is still investigating the cause, the fire risk is likely due to corrosion of an electrical connection inside the Pacifica’s 12-volt battery system. This system is used to power auxiliary features, including radios and garage door openers, and is not part of the vehicle’s plug-in hybrid propulsion system. However, only hybrid vehicles are included in this recall.

According to the NHTSA defect report, “Certain 2017-2018 Chrysler Pacifica Hybrid vehicles may experience a fire, even with the ignition in the “OFF” mode. A vehicle fire can result in an increased risk of occupant injury and/or injury to persons outside the vehicle, as well as property damage.”

Because the remedy is under development, Chrysler is advising owners of these hybrid vehicles to refrain from recharging them and to park them away from structures and other vehicles. Owners can keep operating the vehicles using the internal combustion engine.

Ford Electric – Charge Cord Overheating

Posted on by

Ford will be asking owners of certain 2013-2015 Ford C-Max Energi and Fusion Energi, and 2012-2015 Ford Focus Electric vehicles, to return to their dealers for a problem affecting the 120V convenience charge chord. (Cords affected include part numbers FM58-10B706-AA, FM58-10B706-AB, FM58-10B706-AC, FM58-10B706-AD, FM58-10B706-AE and FM58-10B706-AF.)

According to the defect report, the cord originally provided with these vehicles are missing a thermistor used to identify over temperature conditions. If the defective cord is used in combination with an AC outlet that is not on a dedicated circuit, is damaged, worn or corroded, it could experience an increased contact resistance and could overheat. Early indicators that a problem exists include: incomplete or slow charge cycles, inability to charge, burning odors or visible melting damage.

Dealers will replace the current cord with a new 120V convenience cord with a thermistor. Ford’s number for this recall is 18S24 and the NHTSA campaign number is 18V-592.

Government Incentives Recommended To Improve EV & Hybrid Sales

Posted on by

According to a study done by the National Research Council (NRC), if electric and plug in hybrid vehicles are to be adopted by consumers, the Federal government must continue to provide incentives for buyers. Currently, vehicle cost, battery technology, and lack of consumer knowledge are some areas that the federal government need to address. Developing less expensive, better performing batteries to reduce cost, and a market strategy, is needed to create awareness and overcome customer uncertainty. Continue reading →
