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 2017 Ford Transit Courier 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.
Lamps and electrical
Three faults. The strongest is the brake light (rear): 4.8 times as often as on similar cars.
Figures below are measured across the 1,253 of 1,266 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.
Brake light (rear)
What it means
All stop lamps missing or not working is graded Dangerous, and so is a stop lamp that stays on when the brakes are released. A stop lamp that is missing or not working is Major. On some vehicles with LED rear lamps, part of the stop lamp can go out when the rear fog lamp is lit, which is not regarded as a defect.
Headlight
What it means
On vehicles first used on or after a set date, a halogen headlamp unit converted to take HID or LED bulbs fails for light source and lamp not compatible, which is Major. A complete unit built with those light sources is not failed for that. The precise position of the lamps is not part of the inspection beyond a visual look to see that they sit at about the same height and distance from each side.
Number plate lights (rear)
What it means
Registration plate lamps must light up the rear registration plate and operate at the same time as the position lamps. A missing or inoperative lamp is Major when the plate has only one lamp or all its lamps are not working, and Minor when the plate has several lamps or light sources and not all have failed. A lamp throwing direct white light to the rear is also Minor.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.
Noise, emissions and leaks
One fault: diesel emissions test (compression-ignition rules for vehicles from 01/01/2014), 3.6 times as often as on similar cars.
Diesel emissions test (compression-ignition rules for vehicles from 01/01/2014)
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.
Suspension
Two faults. The strongest is the coil spring (rear): 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.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 33 first tests, 2.3 times as often as on similar cars.
Suspension arm ball joint (front)
What it means
A suspension arm ball joint is failed under the general suspension pin, bush or joint wording. Excessively worn is Major, and 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 47 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.
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.
Rigid brake pipes (front)
Transmission oil leaks
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
- 66in every 100
- Passed on the first test.
- Fixed at the station
- 10in every 100
- Failed, then fixed at the test station the same day.
- Failed
- 24in every 100
- Did not pass, and were not fixed at the test station.
First-attempt pass 65.5% of 3,673 first tests (2025): only cars that passed first time count. Official-style pass 75.6%: cars fixed at the test station also count as a pass. The 10 fixed and the 24 not fixed make the 34 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, 67 in every 100 passed first time.

| 2014 | 60 in every 100 | 969 |
| 2015 | 59 in every 100 | 3,236 |
| 2016 | 64 in every 100 | 2,563 |

If you are buying one
What this year's MOT record means for the decision in front of you.
Mileage matters most on a 2017 Transit Courier.
Of 2017 Transit Courier vehicles with under 62,000 miles, 76 in every 100 passed their 2025 MOT first time. With 128,000 miles or more, 60 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 62,000 | 85,000–105,000 | 128,000 and over | |
|---|---|---|---|
| Brake light | 4.2 | 6.1 | 6.5 |
| Coil spring (rear) | 3.1 | 4.5 | 4.6 |
| Tyre tread depth (front) | 2.0 | 3.7 | 4.5 |
| Suspension arm ball joint (front) | 1.3 | 3.7 | 5.6 |
| Headlight aim | 1.7 | 2.8 | 3.3 |

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.
