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 4 years is 24, and the age of the vehicle is 4, the PPMY index can then be calculated as
