Nissan Leaf: Navigating the Battery Recall and Fire Hazard Challenge

Expanding Recall: Thousands More Nissan Leaf EVs Susceptible to Fire Hazard

Nissan's second-generation Leaf electric vehicles are confronting an escalating battery predicament, with an additional 19,077 units from the 2021 and 2022 model years now being recalled in the United States. This expansion adds to the 23,887 vehicles from 2019 and 2020 models previously recalled for an identical issue, bringing the total number of potentially at-risk vehicles to nearly 43,000. Owners of these vehicles are cautioned against frequent use of DC fast chargers due to a significant fire risk.

The Underlying Cause: Lithium Deposits and Overheating During Fast Charging

The core of the problem lies within the high-voltage lithium-ion batteries, which, particularly in both 40- and 62-kilowatt-hour variants produced in Smyrna, Tennessee, can develop excessive lithium deposits. This phenomenon increases internal resistance within the battery cells. When these affected batteries are subjected to DC fast charging, the heightened resistance can generate substantial heat, posing a serious risk of fire if charging continues unchecked. Approximately one percent of the recalled vehicles are estimated to contain these defective batteries.

Persistent Delays in Resolution: The Unmet Promise of a Software Update

Despite the initial recall in late 2024, Nissan has yet to provide a definitive remedy. The company had initially pledged a software update to mitigate the fire risk by November 2024, a deadline that was subsequently extended to spring 2025, and then to the third quarter of 2025. As of now, the critical software fix remains unavailable, leaving a large number of Leaf owners without a permanent solution to safely utilize DC fast charging capabilities.

Implications for Owners: Adapting to Charging Limitations

The absence of a timely fix presents considerable challenges for affected Nissan Leaf owners. They are currently advised to restrict their charging to Level 1 or Level 2 chargers and to avoid DC fast chargers altogether. This limitation is particularly impactful given that the Leaf's CHAdeMO fast-charging port, while still present in some charging networks, is less prevalent than CCS or NACS standards, further complicating charging options for owners during this recall period. Nissan has indicated that repair invitation letters will be dispatched once the software remedy is finalized and ready for deployment.
