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 2021 Chrysler 300 in the United States are 16,727 units [1]. If the total number of problems reported by Chrysler 300 owners in the last 5 years is 25, and the age of the vehicle is 5, the PPMY index can then be calculated as
PPMY Index = 25 / 16,727 / 5 * 1000 = 0.30.
