Every Jaguar Xj model year
Pass rates fall as cars age, so the only fair comparison for a 2011 car is other cars of the same age. The full run for the Jaguar Xj:

What this means if you are buying a 2011 Xj
The 2011 sits close to the Jaguar Xj average, so there is no strong model-year signal either way. Judge the individual car on its own history. Check the exact car with the free MOT history checker before you buy, and run its VIN and mileage through our free VIN decoder and clocking check.
What a 15-year-old car fails on
A 2011 car is 15 years old now, and age drives the failure mix more than the badge does. Across all cars tested, these are the categories that actually cause failures:
- Lights and electrical: 10.36% of all cars tested
- Suspension: 8.65% of all cars tested
- Tyres: 6.23% of all cars tested
- Brakes: 6.1% of all cars tested
- Visibility: wipers, washers, glass: 4.65% of all cars tested
- Body, chassis and structure: 3.18% of all cars tested
That is above average and into the range where cambelts and water pumps are due if they have not already been done, so ask for the service history rather than take the mileage on trust. On a 2011 Jaguar Xj the average at test was 101,135 miles, so treat anything far above that as a car that has worked harder than its peers, and anything far below as one worth checking for the faults that come from standing still.
The strongest year for this model is 2019 at 91.1%, and the weakest in our data is 2004 at 72.4%. That 18.7 point spread across the model's life is why comparing a 2011 car against a newer one tells you very little.
