"Nissan has a growing battery problem. Nearly 43,000 second-generation Leaf electric vehicles sold in the United States are at risk of catching fire when using a DC fast charger due to an issue with their high-voltage batteries. On top of that, no fix is available yet, and owners are being advised not to frequent fast charging stations in the meantime."
"According to NHTSA filings, the affected vehicles' high-voltage lithium-ion batteries may generate excessive lithium deposits within their cells, which increases resistance and can potentially cause a fluctuation in the state of charge. When using a DC fast charger, the increased electrical resistance in the cells can create a lot of heat, and if charging continues, the battery may catch fire. Both the 40- and 62-kilowatt-hour battery packs that have been manufactured in Smyrna, Tennessee, are covered under the two recalls."
Nearly 43,000 second-generation Nissan Leaf EVs from model years 2019 through 2022 have been recalled for a high-voltage battery defect that can cause fires during DC fast charging. Two recalls cover 23,887 vehicles from 2019–2020 and 19,077 vehicles built between June 15, 2021 and May 23, 2023. Affected 40- and 62-kWh lithium-ion battery packs manufactured in Smyrna, Tennessee can generate excessive lithium deposits, increasing internal resistance and causing state-of-charge fluctuations. During DC fast charging the resistance can produce excessive heat and potentially ignite the battery. Nissan estimates about 1% of affected vehicles have defective batteries, and no fix is available yet.
