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 2007 Nissan Navara 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.
Body and structure
Three faults. The strongest is the propeller shaft joints (front): 19 times as often as on similar cars.
Figures below are measured across the 741 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.
Propeller shaft joints (front)
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 26 first tests, 139 times as often as on similar cars.
Fuel tank
What it means
A fuel tank, pipe or hose that is insecure is Major, and graded Dangerous when so insecure there is a risk of fire. The check covers all permanently attached fuel tanks, including gas tanks and cylinders, and hydrogen tanks on fuel cell vehicles count as fuel tanks. A missing heat shield fails a vehicle only where there is a risk of fire with other fuel system components.
Chassis condition (rear)
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 49 first tests, 5.3 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.
Suspension
Two faults. The strongest is the suspension spring mounting area (rear): 15 times as often as on similar cars.
Suspension spring mounting area (rear)
What it means
Testers check the strength and continuity of the load bearing structure within a set distance of a spring, sub-frame or suspension mounting, an area DVSA calls a prescribed area. Strength that is significantly reduced, or an area inadequately repaired, is Major. Structure so weakened that control of the vehicle is likely to be adversely affected is graded Dangerous.
Wheel bearings (front)
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 35 first tests, 3.5 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
Two faults. The strongest is the brake efficiency below minimum (roller test): 5.0 times as often as on similar cars.
Brake efficiency below minimum (roller test)
Brake imbalance across an axle (roller test, efficiency check, rear)
What it means
A wheel giving less than a set share of the maximum effort from the other wheel on the same axle is Major. On a steered axle, less than half is graded Dangerous. Testers disregard an imbalance if the lower effort is the result of a locked wheel, or if the higher effort from a wheel is at or below a low set figure.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.
Lamps and electrical
One fault: horn, 4.1 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: airbag warning light, 2.7 times as often as on similar cars.
Airbag warning light
What it means
The airbag warning lamp (SRS MIL in DVSA's wording) is failed only if it indicates a system malfunction, which is Major. A lamp lit to show the passenger airbag is disabled is not to be regarded as a defect. Dashboard messages are not a defect in their own right, though they can help the tester confirm a malfunction.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.
Steering
One fault: track rod end (front), 2.6 times as often as on similar cars.
Track rod end (front)
What it means
A steering ball joint with excessive wear or free play is Major, and one worn to the extent there is a serious risk of detachment is graded Dangerous. A dust cover that is damaged but still keeps dirt out is Minor, and one missing or no longer keeping dirt out is Major. Testers must tell wear from a joint's built-in clearance or spring loading.
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.
Suspension arm ball joint (front)
Anti-roll bar linkage ball joints (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
- 55in every 100
- Passed on the first test.
- Fixed at the station
- 8in every 100
- Failed, then fixed at the test station the same day.
- Failed
- 37in every 100
- Did not pass, and were not fixed at the test station.
First-attempt pass 54.8% of 1,638 first tests (2025): only cars that passed first time count. Official-style pass 62.6%: cars fixed at the test station also count as a pass. The 8 fixed and the 37 not fixed make the 45 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, 53 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.
