Jaguar XF owners have reported a total of 339 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 XF. The 2009 Jaguar XF cars have the most problems reported (106 problems).
The following chart shows the 19 most common problems for Jaguar XF cars. The number one most common problem is related to the vehicle's fuel system, other (72 problems). The second most common problem is related to the vehicle's air bags (67 problems).
|Problem Category||Number of Problems|
|Other Fuel System|
|Engine And Engine Cooling|
|Vehicle Speed Control|
|Gasoline Fuel System|
|Electronic Stability Control|
|Unknown Or Other|
It would not be fair to compare the Jaguar XF 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 XF 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 XF 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 XF is to use the total number of problems reported during the vehicle's first year in service, as shown in the Table 4.
