The line compares submitted complaints per 1,000 estimated vehicle-years, not failures per 1,000 cars. Vehicle-years use compiled US sales, a 0.25 prior-calendar-year plus 0.75 current-calendar-year model-year allocation, and the shipped survival curve. Rates appear only where estimated vehicles in operation are at least 5,000.
