Porsche Boxster owners have reported a total of 214 problems for their cars built in the 16 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 Boxster. The 1998 Porsche Boxster cars have the most problems reported (43 problems).
The following chart shows the 18 most common problems for Porsche Boxster cars. The number one most common problem is related to the vehicle's engine and engine cooling (62 problems). The second most common problem is related to the vehicle's air bags (32 problems).
|Problem Category||Number of Problems|
|Engine And Engine Cooling|
|Vehicle Speed Control|
|Gasoline Fuel System|
|Other Fuel System|
It would not be fair to compare the Porsche Boxster 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 Boxster 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 Boxster 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.
Another way to measure the reliability across the model years of the Porsche Boxster is to use the total number of problems reported during the vehicle's first year in service, as shown in the Table 4.
