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 2012 Toyota Sequoia in the United States are 14,581 units [1]. If the total number of problems reported by Toyota Sequoia owners in the last 13 years is 30, and the age of the vehicle is 13, the PPMY index can then be calculated as
PPMY Index = 30 / 14,581 / 13 * 1000 = 0.16.
