How these numbers are calculated
complaints per 1,000 sold = NHTSA owner complaints filed for model years 2015–2022 ÷ U.S. vehicles sold in calendar years 2015–2022 × 1,000
Complaints come from NHTSA's public owner-complaint database (NHTSA data), counted once per complaint and matched across NHTSA's trim and body-style names. Vehicles sold are published U.S. calendar-year sales per nameplate. Model years with fewer than 5,000 sold are too few to rate and are left out. A brand gets a score only when its covered models number at least 3 and make up at least 70% of its U.S. sales; rates under 10% apart are called close.
This is the federal complaint rate, not an owner survey or repair-frequency figure. Consumer Reports publishes a survey-based ranking that measures something different. Full method and brand ranking.
