  Compare Reliability Across Model Years Using PPMY Index

It would not be fair to compare the Chevrolet Aveo of an older model year to newer model years since older vehicles have been in service longer and thus are expected to have more problems. In order to compare the reliability across Aveo model years, we use the PPMY index which is defined as the problems reported per thousand vehicles per Year. A smaller PPMY index indicates greater reliability of the given model year cars.

    PPMY = P / S / Y * 1000,

where P = total problems reported during the life of a Chevrolet Aveo model year; S = total units sold of the model year; Y = years since the debut of the model year (the age of the vehicle).

The results are shown in Table 3.

  Number of Problems Reported During the First Year

Another way to measure the reliability across the model years of the Chevrolet Aveo is to use the total number of problems reported during the vehicle's first year in service, as shown in the Table 4.
