Jaguar XK owners have reported a total of 54 problems for their cars built in the 12 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 XK. The 2007 Jaguar XK cars have the most problems reported (16 problems).
The following chart shows the 18 most common problems for Jaguar XK cars. The number one most common problem is related to the vehicle's vehicle speed control (9 problems). The second most common problem is related to the vehicle's electrical system (6 problems).
|Problem Category||Number of Problems|
|Vehicle Speed Control|
|Engine And Engine Cooling|
|Other Fuel System|
|Gasoline Fuel System|
|Electronic Stability Control|
|Unknown Or Other|
It would not be fair to compare the Jaguar XK 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 XK 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 XK 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.
