2021 Nissan Leaf Fuel System Problems

The 62kWh High-Voltage Lithium-Ion Battery Pack. The vehicle is currently in my possession in Santa Fe, NM, and is available for inspection. It exhibits physical degradation (40.07% Hx) directly linked to the cell defects described in Recall 25V655. The vehicle is a documented fire risk. Per Recall 25V655, internal lithium deposits create resistance that leads to thermal incidents. Because my battery already shows terminal degradation (40.07% Hx and 3.18V sag), the risk of a fire during charging or operation is imminent. Furthermore, Nissan has banned Level 3 Fast Charging, which leaves me with no way to safely recharge the vehicle during necessary travel, creating a risk of being stranded in unsafe conditions. A terminal battery failure was officially diagnosed by an authorized Nissan dealer in Albuquerque in August 2025 at 108,000 miles. However, my local dealer (Fiesta Nissan in Santa Fe) has since refused to intake the vehicle for the recall because they are not EV-certified. Yes, by an authorized Nissan Dealer. As noted, the failure was confirmed in August 2025. Additionally, the vehicle is subject to a formal manufacturer safety recall (25V655 / R25C8) specifically for this battery defect. Symptoms appeared in August 2025 including severe range loss and power turtle mode. LeafSpy Pro diagnostics confirm a terminal 40.07% Hx rating and a dangerous 3.18V cell sag under load. Nissan's March 2026 recall notice confirms there is no current remedy to address these physical symptoms, and the proposed software 'fix' only monitors for failure rather than repairing the defective cells. Car immediately shut down on me on the Highway(around 55mph) and I was able to coast out of traffic and onto the shoulder. Car indicated having battery percentage around 58%(30KWH) still remaining. car also would not shift into neutral because battery was too low so towing was difficult. no neutral overide on car if battery is "dead".

I am submitting this letter as a formal safety complaint concerning NHTSA Recall No. 25V655000, which affects my 2021 Nissan LEAF SV and results in the continued restriction of DC fast charging due to a reported fire risk, without an available or timely remedy. Under this recall, Nissan has restricted the vehicle’s ability to safely utilize DC fast charging. While I understand and support actions taken to mitigate fire risk, the absence of a corrective repair or defined resolution timeline has effectively removed a core operational capability of the vehicle on an indefinite basis. DC fast charging is a fundamental feature of the Nissan LEAF and was a material factor in my decision to purchase the vehicle. Since the recall was implemented, the vehicle cannot be used as designed or marketed for time-constrained travel, despite otherwise being mechanically operable. I was advised that a corrective update or repair would be available and, based on that representation, scheduled a service appointment with an authorized Nissan dealer on December 29, 2025. At that appointment, I was informed that no fix currently exists and that the restriction remains indefinite. No interim remedy, alternative accommodation, or estimated timeline was provided. As it stands, the recall has resulted in a vehicle that cannot safely perform a core function for which it was sold, with no effective remedy in place. Owners are effectively required to accept an indefinite loss of functionality to mitigate a safety risk, raising concerns about defect resolution timelines, adequacy of interim measures, and consumer safety implications. I appreciate NHTSA’s role in ensuring vehicle safety and accountability, and I am submitting this complaint to support appropriate oversight and review.
