Lightning eMotors, Inc. (“LeM”) has decided that a defect which relates to motor vehicle safety exists in certain Model Year 2020 FT3-43 and FE4-86, Model Year 2019-2021 FE4-129, and Model Year 2019 – 2022 FT3-86 vehicles equipped with eMatrix Energy Systems battery packs. This action involves vehicles in which LeM powertrains were installed from January 1, 2020, through February 2, 2022, and which use eMatrix Energy Systems battery packs. Our records indicate that your vehicle(s) listed above may be affected.
What is the Problem?
Defective structural welds and internal radiator leaks have been found in the eMatrix battery packs installed in these vehicles. These conditions may result in isolation faults and cell imbalances that may cause a loss of traction drive, which may increase the risk of a crash, or thermal runaway, which may increase the risk of a fire.
What Are We Doing About the Problem?
LeM will replace the eMatrix batteries with a non-defective battery, free of charge. If a replacement battery is unavailable, LeM will discuss alternative remedy options with you. Please contact LeM at support@lightningemotors.com or 970-744-4926 for more information.
