Jaguar Xjs: MOT pass rate and reliability data

The Jaguar Xjs passes its MOT first time more often than the average UK car, by 4.7 percentage points. These figures come from the DVSA's full year of anonymised MOT results, covering 3,107 individual Jaguar Xjs tests. Nothing here is an estimate or a survey.

The numbers

What this means if you are buying one

A 81.4% first-time pass rate means roughly 19 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 Xjs tested had covered 81,044 miles and was built around 1991.

What this means at salvage auction

Pass rate is a proxy for what a car costs to keep on the road. The Jaguar Xjs sits 4.7 points above the national average, ranked 1,401 of 2,005 models. On one bought as 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 Xjs 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 recorded closing bids for damaged Jaguar Xjs at UK salvage auction.

Most common MOT failures on a Jaguar Xjs

1. Parking brake efficiency less than 50% of the required value, 2% of tests (5.53x the national rate for this defect)
2. Emissions levels exceed default limits, 1.9% of tests (5.37x the national rate for this defect)
3. Audible warning inoperative, 1.4% of tests (4.91x the national rate for this defect)
4. Vehicle structure corroded to the extent that the rigidity of the assembly is seriously reduced, 1.5% of tests (3.66x the national rate for this defect)
5. Significant brake effort recorded with no brake applied indicating a binding brake, 3.7% of tests (3.57x the national rate for this defect)
6. A direction indicator lamp missing, inoperative or in the case of a multiple light source more than 1/2 not functioning, 1.6% of tests (2.41x the national rate for this defect)
7. Parking brake inoperative on one side, 1.4% of tests (2.27x the national rate for this defect)
8. 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, 2% of tests (2.08x the national rate for this defect)
9. Parking brake efficiency below minimum requirement, 2.4% of tests (1.83x the national rate for this defect)
10. Windscreen washers not working or not providing sufficient fluid to clear the windscreen, 2.7% of tests (1.62x the national rate for this defect)

From 3,107 DVSA-tracked Jaguar Xjs tests, 2024. DVSA testers marked 3.85% of these flagged Jaguar Xjs defects as "dangerous", meaning the tester judged the car unsafe to drive away, against 5.11% nationally.

Most common MOT advisories on a Jaguar Xjs

An advisory doesn't fail the car - the tester flags it as worth watching, but it still passes. A different list from the failures above: what testers are noting on a Jaguar Xjs before it actually fails on it.

1. Power steering fluid leaking or system malfunctioning, 5.2% of tests (21.59x the national rate for this advisory)
2. A wheel bearing with excessive play, 13.3% of tests (20.48x the national rate for this advisory)
3. Fluid leaking excessively and likely to harm the environment or to pose a safety risk to other road users, 20.5% of tests (3.69x the national rate for this advisory)
4. Vehicle structure corroded to the extent that the rigidity of the assembly is seriously reduced, 3.5% of tests (2.79x the national rate for this advisory), also fails
5. A spring or spring component fractured or seriously weakened, 12.9% of tests (2.74x the national rate for this advisory)
6. 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, 3.9% of tests (2.59x the national rate for this advisory), also fails
7. Significant brake effort recorded with no brake applied indicating a binding brake, 4.1% of tests (2.06x the national rate for this advisory), also fails
8. Exhaust system leaking or insecure, 4.2% of tests (1.48x the national rate for this advisory)
9. A suspension pin, bush or joint excessively worn, 12.9% of tests
10. A tyre seriously damaged, 9.8% of tests
