Jaguar Xj: MOT pass rate and reliability data

The Jaguar Xj passes its MOT first time more often than the average UK car, by 1.6 percentage points. These figures come from the DVSA's full year of anonymised MOT results, covering 23,688 individual Jaguar Xj tests. Nothing here is an estimate or a survey.

What this means if you are buying one

A 78.3% first-time pass rate means roughly 22 in every 100 Jaguar Xjs presented for MOT fail on the first attempt. That is better than average, so a well-kept example is a reasonably safe used buy. The average Jaguar Xj tested had covered 91,234 miles and was built around 2007.

What this means at salvage auction

Pass rate is a proxy for what a car costs to keep on the road. On a Jaguar Xj bought as a repairable salvage, the mechanical side is less likely to spring surprises, so your repair estimate should hold up reasonably well.

Before you bid: run the lot through the analyzer, check the car's own record, check the mileage, decode the VIN, and if it carries a marker use the write-off value calculator. Or compare it against another model.

Looking at a specific Jaguar Xj rather than the model in general? The free check covers its MOT and mileage history, and the full HPI report confirms the insurance write-off category, outstanding finance and whether it is recorded stolen, from licensed data for 5 credits. Already own one that has been damaged? Work out whether fixing it beats selling it with the repair or scrap calculator, and see what damaged Jaguar Xjs actually sold for at UK salvage auction.

  3. Vehicle structure corroded to the extent that the rigidity of the assembly is seriously reduced, 1% of tests (2.63x the national rate for this defect)
  4. Emissions levels exceed default limits, 0.7% of tests (2.52x the national rate for this defect)
  5. The strength or continuity of the load bearing structure within 30cm of any sub-frame, spring or suspension component mounting (a 'prescribed area') is significantly reduced or inadequately repaired, 1.6% of tests (1.94x the national rate for this defect)
  6. A suspension pin, bush or joint excessively worn, 3.3% of tests
  7. Tyre tread depth not in accordance with the requirements, 1.5% of tests

From 49,539 DVSA-tracked Jaguar Xj tests, 2024. DVSA testers marked 4% of these flagged Jaguar Xj defects as "dangerous", meaning the tester judged the car unsafe to drive away, against 4.97% nationally.

Jaguar Xj pass rate by model year

Pass rates fall steadily as cars age, so the model year matters as much as the model. First-time pass rate for each Jaguar Xj year:

Diesel and petrol versions of the same car fail on different things, so the fuel type moves the number:
