Known issues

High

Passive air cooling is the central reliability story. Hot-climate Leafs (Phoenix, Texas, Florida) lose capacity 2-3x faster than mild-climate cars. Geotab data shows the air-cooled Leaf as an outlier on the steep end of the degradation curve.

Medium

DC fast charging (CHAdeMO) heats the pack quickly with no liquid cooling to dissipate it. Multiple consecutive fast charges trigger 'rapidgate' — Nissan's BMS taper that limits charge rate to protect cells. Long-trip usability suffers.

High

Ultra-high-mileage 2018-2019 40 kWh packs in hot states have hit warranty replacement at 70-80,000 miles. Out-of-warranty replacement cost is high relative to vehicle resale value.

Medium

Battery warranty was 8 years / 100k miles to 9 of 12 capacity bars (~67%) — a less protective floor than the 70% standard on most newer EVs.

How this pack ages (industry context)

Industry fleet aggregates: 2.3% average annual capacity loss across 22,700 EVs / 21 models (Geotab, 2026), and 95% range retention at 5 years on average across 30,000+ vehicles (Recurrent, 2026).

OEM warranty floor on this pack: 8 yr / 100k mi to 67% capacity.

Public per-pack degradation curves are not available for most models. Individual results vary materially with climate, charging behavior, and DC fast-charge frequency.

24V700000 15/11/2024 ELECTRICAL SYSTEM:PROPULSION SYSTEM:TRACTION BATTERY

Nissan North America, Inc. (Nissan) is recalling certain 2019-2020 LEAF vehicles equipped with a Level 3 quick charging port. The lithium-ion battery may overheat during Level 3 charging.

Consequence: A quick charging battery that overheats increases the risk of a fire.

Affects: Nissan Leaf 2018-2024
