2021 Nissan LEAF

Across the second-generation LEAF's federal record, complaints peaked dramatically in 2019 at 251 — by far the highest in the generation — before declining to 158 in 2020 and then dropping sharply to 51 for the 2021 target year, the lowest full-production-year figure since 2016. Recalls followed a similar downward arc, falling from six in 2020 to four in 2021, while TSBs continued a steady decline from 121 in 2018 to 83 in 2021, suggesting diminishing manufacturer service activity as the platform matured. The 2021 model's top complaint concentration is in the Electrical System (20 of 51 complaints), with a smaller spread across Unknown/Other (5), Visibility/Wiper (4), and a combined Power Train/Electrical/Fuel Propulsion category (2); the data also records 2 crash complaints and 3 fire complaints, though the JSON does not specify root causes for any of these. Notably, 2021 sits firmly on the downslope of the generation's complaint arc, with roughly one-fifth the complaint volume of the 2019 peak and well below the 2020 figure, implying that many of the issues driving the 2019–2020 surge had been engineered out or addressed by this point in the production cycle. Given the meaningfully lower complaint volume, stable recall count, and reduced TSB activity relative to the preceding two years, the 2021 LEAF appears to be a comparatively stronger model year within this generation and represents a reasonable used-EV purchase, with the caveat that the electrical-system complaint cluster warrants a thorough pre-purchase inspection of charging and high-voltage components.
