Mileage

XJ mileage by age

The median reading at the test: half the cars of that age had covered more, half less. Estimated from 1,000-mile bands, for cars up to 25 years old.

A car well above or below the typical figure is not a problem in itself, but the readings should rise steadily from one MOT to the next. A fall, or a long gap, is worth asking about.

Questions

Jaguar XJ: common questions

Contains DVSA MOT data, Open Government Licence v3.0, year 2025.

What is the most common MOT failure on the Jaguar XJ?

In DVSA's 2025 test records, the area that failed most often on the Jaguar XJ was suspension: 8.8% of initial tests had at least one fail or PRS item there, against 9.0% for all cars and vans. Next came lamps, reflectors and electrical equipment (7.1%) and brakes (5.9%).

What is the MOT pass rate for the Jaguar XJ?

76.3% of 27,415 initial MOT tests on the Jaguar XJ in 2025 were a pass first time. Another 3.1% passed after small repairs made at the test station within the hour (PRS). Across all cars and vans, 72.1% passed first time.

Does a lower pass rate mean the Jaguar XJ is unreliable?

Not on its own. MOT results depend on age, mileage and upkeep as much as on design, so a model with many older cars on the road will usually fail more often. The table by year compares cars of a similar age. What matters most is the record of the car you are looking at, so check its MOT history before you buy.

What counts as a dangerous defect?

One the tester judges to be a direct and immediate risk to road safety, or to have a serious impact on the environment. The car fails and should not be driven until it is repaired. 6.2% of initial tests on the Jaguar XJ found at least one, against 7.3% for all cars and vans.

Where do these figures come from?

From DVSA's anonymised MOT test data for 2025, published under the Open Government Licence. We count initial tests on cars and light vans in Great Britain, as DVSA does in its own statistics: retests, appeals and abandoned tests are left out, and so are advisories and minor defects.
