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 2015 Renault Trafic 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
Five faults. The strongest is the anti-roll bar pins and bushes (front): 8.6 times as often as on similar cars.
Figures below are measured across the 4,220 of 4,261 failed first attempts (99.0%) 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.
Anti-roll bar pins and bushes (front)
What it means
An anti-roll bar pin or bush that is excessively worn is Major, and one likely to become detached is graded Dangerous. The wording is DVSA's general rule for a suspension pin, bush or joint.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 114 first tests, 8.9 times as often as on similar cars.
Anti-roll bar linkage ball joints (front)
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 232 first tests, 4.1 times as often as on similar cars.
Anti-roll bar ball joint (front)
What it means
On an anti-roll bar ball joint, DVSA fails a suspension pin, bush or joint that is excessively worn as Major. One 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 42 first tests, 3.4 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.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 455 first tests, 3.0 times as often as on similar cars.
Coil spring (rear)
What it means
A missing bump stop rubber is not a reason to fail a coil spring. When the vehicle is jacked and lowered, a spring that does not correctly locate as the suspension returns to its normal running position is rejected as insecurely attached. A missing spring is Major, and graded Dangerous where directional control is affected.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage. Advisories count notes recorded on failed first tests only.
Steering
One fault: track rod end (front), 6.0 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.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 212 first tests, 4.2 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.
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 sub-frame pins and bushes (front)
Brake pedal
Brake light (rear)
Seat belt condition (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
- 57in 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
- 38in every 100
- Did not pass, and were not fixed at the test station.
First-attempt pass 56.8% of 9,873 first tests (2025): only cars that passed first time count. Official-style pass 62.0%: cars fixed at the test station also count as a pass. The 5 fixed and the 38 not fixed make the 43 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.

If you are buying one
What this year's MOT record means for the decision in front of you.
Mileage makes a modest difference on a 2015 Trafic.
Of 2015 Trafic vehicles with under 78,000 miles, 64 in every 100 passed their 2025 MOT first time. With 150,000 miles or more, 57 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 78,000 | 100,000–121,000 | 150,000 and over | |
|---|---|---|---|
| Track rod end (front) | 9.8 | 13.1 | 10.3 |
| Coil spring (rear) | 5.4 | 8.5 | 4.8 |
| Anti-roll bar linkage ball joints (front) | 5.1 | 6.4 | 6.0 |
| Shock absorbers (front) | 3.4 | 5.5 | 4.2 |
| Diesel engine warning light | 2.1 | 3.0 | 3.3 |
Faults per 100 first tests, by the car's mileage at the test.

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.
