Porsche Cayenne - Problems, Statistics, and Analysis

Porsche Cayenne owners have reported a total of 403 problems for their cars built in the 14 model years listed in the chart below. The chart shows the number of problems reported across all service years for each given model year of the Porsche Cayenne. The 2004 Porsche Cayenne cars have the most problems reported (128 problems).

  Compare Reliability Across Model Years Using PPMY Index

It would not be fair to compare the Porsche Cayenne 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 Cayenne 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 Porsche Cayenne 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 Porsche Cayenne is to use the total number of problems reported during the vehicle's first year in service, as shown in the Table 4.
