Jaguar XJ 2009: reliability & common MOT faults

In 2025, 69 in every 100 first MOTs on a 2009 Jaguar XJ were passes.

Summary

With 504 first tests, there are too few to say whether the 2009 Jaguar XJ differs from the model years either side. Treat the faults below as a checklist.

How we count this. Data: UK MOT open data, 2025. Only Class 4 cars on their first MOT of the year are counted. A car that fails and is fixed at the test station still counts as a fail in the first-attempt rate. These are raw results, not adjusted for age, mileage, or peer mix. The MOT does not test engine or gearbox internals.

Advisories

Other things testers noted as worn or close to failing, more often than on similar cars.

An advisory is a note from the tester about something that has not failed yet. It is an early warning, not a fail.

Data: UK MOT open data, 2025. Counts cover advisories recorded on failed first tests only, compared with cars of the same age and mileage.

MOT pass rates

How first tests ended, and how the pass rates are counted.

Passed first time
69in every 100
Passed on the first test.
Fixed at the station

Failed, then fixed at the test station the same day.

Did not pass, and were not fixed at the test station.

First-attempt pass 68.7% of 504 first tests (2025): only cars that passed first time count. Official-style pass 74.6%: cars fixed at the test station also count as a pass. The 6 fixed and the 25 not fixed make the 31 in every 100 that did not pass first time.

Newer cars are younger, so look for a jump rather than the climb. A year earlier (2024), when these cars were a year younger, 74 in every 100 passed first time.

FAQs

Short answers about how to read this model-year guide.

With 504 first tests, there are too few to say whether the 2009 Jaguar XJ differs from the model years either side. Treat the faults below as a checklist. In 2025, 68.7% of 504 first MOTs on the 2009 Jaguar XJ passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 74.6%. Among 158 failed first-attempt MOT tests (test year 2025), we highlight MOT failure patterns that show up more often than on cars of a similar age and mileage when the sample is large enough to trust. There is no single reliability score here; this is a pre-purchase checklist built from DVSA open data, not a guarantee for any individual car.
Advisories flag issues noted at the test and are not a fail rate. We show advisory patterns that appear more often than on similar cars among failed first-attempt tests, separate from common failure rows. Use them as early-warning checks, not as a pass/fail score.
This page highlights MOT failure patterns for the 2009 Jaguar XJ (registration year) using UK DVSA open data for the selected test year. Patterns are compared with cars of a similar age and mileage. It is a buyer checklist from MOT defect statistics, not a full service history or manufacturer service-bulletin list.
No. MOT tests do not cover engine internals, gearboxes, or many electronic modules. Patterns here come from MOT defect statistics only and should not be read as engine or gearbox reliability scores.

About this data

How this page is built and what it can (and can't) say.

These figures come from UK MOT open data for this model year. We surface common failure patterns against similar cars, not a full reliability score, and not a pass/fail verdict on any individual vehicle.

2024 2025

What we include

UK Class 4 cars only. Normal MOT tests (not retests); first test per vehicle per calendar year; results pass, PRS, or fail.

Same-day repairs

PRS means the car failed items that were fixed at the test station and then passed the same day. We count PRS as a first-attempt fail in headline rates so same-day repairs do not hide problems.

How we compare

We compare this model year with other Class 4 cars of similar age and mileage in the same test year. This model family is left out of the peer group so the car is not measured against itself.

What this does not cover

  • MOTs do not cover engine internals, gearboxes, or many electronics; this is not a full reliability score.
  • Common faults come from MOT defect stats, not manufacturer TSBs or recalls.
  • Age and mileage matching reduces, but does not remove, differences in how cars were used and maintained.
  • If the data for a car is too thin to say anything useful, we say so rather than guess.
