PPMY Index and Problem Occurrence Trend

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 Nissan Altima in the United States are 310,616 units [1]. If the total number of problems reported by Nissan Altima owners in the last 5 years is 270, and the age of the vehicle is 5, the PPMY index can then be calculated as

PPMY Index = 270 / 310,616 / 5 * 1000 = 0.17.
