Jaguar S-type owners have reported a total of 617 problems for their cars built in the 9 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 Jaguar S-type. The 2000 Jaguar S-type cars have the most problems reported (177 problems).
The following chart shows the 23 most common problems for Jaguar S-type cars. The number one most common problem is related to the vehicle's power train (92 problems). The second most common problem is related to the vehicle's suspension (62 problems).
|Problem Category||Number of Problems|
|Engine And Engine Cooling|
|Vehicle Speed Control|
|Other Fuel System|
|Gasoline Fuel System|
|Unknown Or Other|
|Electronic Stability Control|
It would not be fair to compare the Jaguar S-type 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 S-type 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 Jaguar S-type 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 Jaguar S-type is to use the total number of problems reported during the vehicle's first year in service, as shown in the Table 4.
