In our research we use the PPMY index to compare the reliability of vehicles. The PPMY index of a certain model is defined as the problems reported per thousand vehicles per Year. The total sales of the 2020 Lincoln Navigator in the United States are 17,991 units [1]. If the total number of problems reported by Lincoln Navigator owners in the last 6 years is 36, and the age of the vehicle is 6, the PPMY index can then be calculated as
PPMY Index = 36 / 17,991 / 6 * 1000 = 0.33.
