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.
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.
Wheel condition (rear)
Wheel 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
- 88in every 100
- Passed on the first test.
- Fixed at the station
- 3in every 100
- Failed, then fixed at the test station the same day.
- Failed
- 9in every 100
- Did not pass, and were not fixed at the test station.
First-attempt pass 88.5% of 36,233 first tests (2025): only cars that passed first time count. Official-style pass 91.1%: cars fixed at the test station also count as a pass. The 3 fixed and the 9 not fixed make the 12 in every 100 that did not pass first time.
By fuel type
Figures are in every 100 first tests. Cars with more miles usually fail more often, so the same-mileage figure gives every fuel the mileage mix of all the cars in this year.
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, 89 in every 100 passed first time.

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 2021 MINI Hatch.
Of 2021 MINI Hatch vehicles with under 15,000 miles, 92 in every 100 passed their 2025 MOT first time. With 36,000 miles or more, 86 in every 100 did.
Which fuel?
| Typical mileage | Passed first time, as tested | Passed first time, same mileage | |
|---|---|---|---|
| Petrol | 24,360 miles | 89 | 89 |
| Electric | 20,878 miles | 87 | 86 |
Figures are in every 100 first tests. At the same mileage there is no clear difference between the two.
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 15,000 | 21,000–27,000 | 36,000 and over | |
|---|---|---|---|
| Tyre condition (front) | 3.1 | 3.3 | 3.4 |
| Windscreen wipers (front) | 1.8 | 2.4 | 2.1 |
| Tyre tread depth (front) | 0.2 | 0.5 | 1.1 |
| Brake pads (rear) | 0.1 | 0.6 | 0.9 |
| Headlight aim | 0.4 | 0.4 | 0.5 |
Faults per 100 first tests, by the car's mileage at the test.

of all first tests had a defect the tester marked dangerous (unsafe to drive away).
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.

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.
