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 2000 Fiat Ducato vehicles in 2025, not a prediction that any one car will have them. Faults are grouped by part of the car. They come from MOT defect codes, not manufacturer bulletins, recalls or a diagnosis of any one car.
Suspension
Three faults. The strongest is the suspension sub-frame mounting area (front): 10 times as often as on similar cars.
Figures below are measured across the 569 failed first attempts in 2025 that had a mileage recorded, which allows a like-for-like comparison.
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 sub-frame mounting area (front)
What it means
Structure around a sub-frame mounting that is so weakened that control of the vehicle is likely to be adversely affected is graded Dangerous, whether it is damaged, fractured, corroded or inadequately repaired. It is Major when strength is significantly reduced by excessive corrosion, damage or a fracture, or when it is inadequately repaired.
Suspension mounting area (front)
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 45 first tests, 4.8 times as often as on similar cars.
Shock absorbers (front)
What it means
Slight seepage that leaves a film of fluid on a shock absorber does not fail it. Severe leakage, or damage so that it does not function, is Major. A shock absorber missing or likely to become detached is graded Dangerous, though a missing one is only rejected if shock absorbers were fitted as standard.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage. Advisories count notes recorded on failed first tests only.
Body and structure
Two faults. The strongest is the chassis condition (front): 5.1 times as often as on similar cars.
Chassis condition (front)
What it means
A main load-bearing structural member that is fractured, deformed, modified or inadequately repaired is Major when structural rigidity is significantly reduced, and Dangerous where steering or braking is likely to be adversely affected. Corrosion of the body, cab or chassis at a mounting point is Dangerous where overall security or stability is impaired.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 36 first tests, 4.1 times as often as on similar cars.
Vehicle structure condition (front)
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.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 32 first tests, 3.0 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: rigid brake pipes (front), 3.9 times as often as on similar cars.
Rigid brake pipes (front)
What it means
Chafing, corrosion or damage to a rigid brake pipe justifies rejection once its wall thickness is reduced by a set amount, although DVSA accepts this is not easy to determine. If a tester is not sure, the benefit of the doubt applies. A leaking pipe or connection is graded Dangerous on a hydraulic system and Major on an air system.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 75 first tests, 2.2 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.
Lamps and electrical
One fault: horn, 3.0 times as often as on similar cars.
Horn
What it means
A horn that does not work, or is likely to be confused with an emergency vehicle siren, is graded Major. Gongs, bells, sirens and anything with more than one tone, which includes a horn that alternates between its notes, are not allowed, except a gong, bell or siren on vehicles first used before a set date. Sound defects are Minor for named cases such as a bell or harsh sound, and Major under a general row.
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), 2.5 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.
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.
Power steering pipes and hoses
Wheel bearings (front)
Wheel bearings (rear)
Anti-roll bar linkage pins and bushes (front)
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
- 61in every 100
- Passed on the first test.
- Fixed at the station
- 5in every 100
- Failed, then fixed at the test station the same day.
- Failed
- 34in every 100
- Did not pass, and were not fixed at the test station.
First-attempt pass 60.9% of 1,454 first tests (2025): only cars that passed first time count. Official-style pass 66.2%: cars fixed at the test station also count as a pass. The 5 fixed and the 34 not fixed make the 39 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, 59 in every 100 passed first time.

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.
