Complaints filed with NHTSA by the end of the year after the model year. Sales are Kelley Blue Book estimates for every brand (Tesla doesn't report U.S. sales by model). These scores use a shorter window than the main Lemon Index (complaints filed by the end of the year after the model year), so brand-new EVs like the Cybertruck get a fair, complete window. That's why a Tesla's score here differs a little from its main car page. Sales source: Kelley Blue Book EV sales reports (estimates).
