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.
These are patterns across 2008 Jaguar X-Type vehicles in 2025, not a prediction that any one car will have them. Faults are grouped by part of the car. A wear pattern follows age and use more than the way the car was built. They come from MOT defect codes, not manufacturer bulletins, recalls or a diagnosis of any one car.
Suspension
Five faults. The strongest is the suspension arm (rear): 13 times as often as on similar cars.
Figures below are measured across the 1,337 of 1,338 failed first attempts (99.9%) that recorded an odometer reading in 2025. Mileage is needed to compare like with like.
We only list faults with at least 20 failures and a rate of about 2.0 times that of similar cars, which keeps one-off results out of the list.
Suspension arm (rear)
What it means
A missing bump stop rubber is not a reason to fail a suspension arm. A component that is fractured, missing or likely to fail is graded Dangerous, and one excessively damaged or corroded is Major. On some vehicles, some highly stressed parts are thin pressed steel, and many of those have hollow box sections or up-facing areas that can collect road dirt and salt, so they get special attention.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 174 first tests, 4.8 times as often as on similar cars.
Wheel bearings (rear)
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 39 first tests, 3.3 times as often as on similar cars.
Anti-roll bar linkage ball joints (rear)
What it means
Excessive wear on an anti-roll bar linkage ball joint is Major. A joint likely to become detached is graded Dangerous.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 35 first tests, 2.8 times as often as on similar cars.
Suspension arm pins and bushes (rear)
What it means
Pins and bushes on suspension arms fail as Major when they are excessively worn. They are graded Dangerous when likely to become detached. DVSA uses the same wording for a suspension joint.
Suspension mounting area (rear)
What it means
The load bearing structure within a set distance of a sub-frame, spring or suspension component mounting is a prescribed area. Major applies when its strength or continuity is significantly reduced or it is inadequately repaired. Dangerous applies when it is so weakened that control of the vehicle is likely to be adversely affected.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 75 first tests, 2.1 times as often as on similar cars.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage. Advisories count notes recorded on failed first tests only.
Brakes
One fault and one wear pattern. The strongest is the hydraulic brake callipers (rear): 13 times as often as on similar cars.
Hydraulic brake callipers (rear)
Brake discs (front)
What it means
A brake disc or drum must be significantly worn before it is rejected, and being worn below the manufacturer's recommended limits is not a reason in itself. Significantly and obviously worn is Major, as is contamination with oil or grease. A disc or drum that is fractured, insecure, seriously weakened or missing is graded Dangerous.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.
Seat belts and restraints
One fault: seat belt mounting area (front), 8.5 times as often as on similar cars.
Seat belt mounting area (front)
What it means
A seat belt anchorage likely to become detached in the event of a collision is graded Dangerous. The load bearing structure near an anchorage, called a prescribed area, is Major when its strength or continuity is significantly reduced or it is inadequately repaired. Anchorage points are inspected for all seat belts fitted, except a belt with no corresponding seat.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.
Noise, emissions and leaks
Two faults. The strongest is the diesel emissions test (compression-ignition rules for vehicles from 01/07/2008): 3.6 times as often as on similar cars.

Diesel emissions test (pre-reg turbo rules before 01/07/2008)
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.
Body and structure
One fault: vehicle structure condition (rear), 2.9 times as often as on similar cars.
Vehicle structure condition (rear)
What it means
Structure that is fractured, deformed, corroded, modified or inadequately repaired is failed on rigidity only if the overall structural rigidity of the vehicle is significantly reduced. Structure that is likely to affect steering or braking adversely is graded Dangerous. Prescribed areas are not covered here, as they are checked under other sections, including brakes and steering.

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. Advisories for the faults above are shown with those faults.

MOT pass rates
How first tests ended, and how the pass rates are counted.
- Passed first time
- 60in every 100
- Passed on the first test.
- Fixed at the station
- 4in every 100
- Failed, then fixed at the test station the same day.
- Failed
- 36in every 100
- Did not pass, and were not fixed at the test station.
First-attempt pass 59.5% of 3,304 first tests (2025): only cars that passed first time count. Official-style pass 64.0%: cars fixed at the test station also count as a pass. The 4 fixed and the 36 not fixed make the 40 in every 100 that did not pass first time.
Same model, other years
Passed first time in every 100, all tested in 2025.
Newer cars are younger, so look for a jump rather than the climb. A year earlier (2024), when these cars were a year younger, 58 in every 100 passed first time.
| Year | Passed first time | First tests |
|---|---|---|
| 2001 | 57 in every 100 | 423 |
| 2002 | 59 in every 100 | 961 |
| 2003 | 57 in every 100 | 1,524 |
| 2004 | 54 in every 100 | 1,847 |
| 2005 | 57 in every 100 | 1,902 |
| 2006 | 58 in every 100 | 2,300 |
| 2007 | 57 in every 100 | 2,464 |
| 2008 This car | 60 in every 100 | 3,304 |
| 2009 | 60 in every 100 | 3,201 |
If you are buying one
What this year's MOT record means for the decision in front of you.
Mileage matters most on a 2008 X-Type.
Of 2008 X-Type vehicles with under 80,000 miles, 75 in every 100 passed their 2025 MOT first time. With 144,000 miles or more, 52 in every 100 did.
What to check at your mileage
How often each fault turned up on a failed first test, by the car's mileage. Read it as: what is likely to need looking at on a car like the one in front of you.
| Under 80,000 | 102,000–120,000 | 144,000 and over | |
|---|---|---|---|
| Suspension mounting area (rear) | 1.7 | 5.8 | 8.2 |
| Individual sidelight or tail light (front) | 1.7 | 3.1 | 7.2 |
| Suspension arm (rear) | 2.9 | 4.2 | 3.4 |
| Tyre condition (front) | 2.3 | 3.9 | 5.8 |
| Handbrake efficiency below minimum (roller test) | 1.7 | 3.0 | 4.3 |

Every figure here is a first-attempt MOT rate from DVSA open data for this model line, for cars of this model year tested in 2025. Each mileage band holds a fifth of the tests. MOTs do not test engine or gearbox internals, so this is a pre-purchase checklist, not a full reliability score.
FAQs
Short answers about how to read this model-year guide.
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.
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.
