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 2018 Renault Captur 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
Two faults. The strongest is the reversing lights: 7.3 times as often as on similar cars.
Figures below are measured across the 4,265 of 4,270 failed first attempts (99.9%) 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.
Reversing lights
What it means
Reversing lamps must show a white light to the rear, and on some vehicles the engine has to be running before they work. A lamp that does not emit a steady white light, does not face the rear or has its light intensity significantly reduced is Major. A lamp not securely attached is Minor, but one likely to become detached is Major.
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.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.
Brakes
Two faults. The strongest is the brake performance (roller test, rear): 5.9 times as often as on similar cars.
Brake performance (roller test, rear)
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 143 first tests, 3.2 times as often as on similar cars.
Handbrake efficiency below minimum (roller test)
What it means
A parking brake with efficiency below the minimum requirement is Major, and graded Dangerous where efficiency is less than half of the required value. On a roller brake tester, the requirement counts as met if more than half of the wheels of a brake system lock. The check applies only to vehicles whose parking brake was not already tested as the secondary brake.
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
Three faults. The strongest is the anti-roll bar linkage ball joint dust cover (front): 4.7 times as often as on similar cars.
Anti-roll bar linkage ball joint dust cover (front)
What it means
A suspension joint dust cover that is severely deteriorated is Minor. It becomes Major once it is missing or no longer prevents the ingress of dirt, so what matters is whether it still keeps dirt out. DVSA words this for any suspension joint dust cover, and files it here under anti-roll bars.
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 59 first tests, 3.0 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.
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.
Brake pedal
Individual direction indicators (rear)
Brake performance (plate test, rear)
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
- 79in every 100
- Passed on the first test.
- Fixed at the station
- 4in every 100
- Failed, then fixed at the test station the same day.
- Failed
- 17in every 100
- Did not pass, and were not fixed at the test station.
First-attempt pass 78.6% of 19,982 first tests (2025): only cars that passed first time count. Official-style pass 83.4%: cars fixed at the test station also count as a pass. The 4 fixed and the 17 not fixed make the 21 in every 100 that did not pass first time.
Petrol and diesel
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, 82 in every 100 passed first time.
| Year | Passed first time | First tests |
|---|---|---|
| 2013 | 55 in every 100 | 5,383 |
| 2014 | 64 in every 100 | 17,288 |
| 2015 | 67 in every 100 | 21,754 |
| 2016 | 73 in every 100 | 23,317 |
| 2017 | 77 in every 100 | 18,711 |
| 2018 This car | 79 in every 100 | 19,982 |
| 2019 | 82 in every 100 | 19,176 |
| 2020 | 87 in every 100 | 12,754 |
| 2021 | 90 in every 100 | 9,348 |
| 2022 | 91 in every 100 | 8,167 |
If you are buying one
What this year's MOT record means for the decision in front of you.
Mileage matters most on a 2018 Captur.
Of 2018 Captur vehicles with under 29,000 miles, 88 in every 100 passed their 2025 MOT first time. With 61,000 miles or more, 68 in every 100 did.
Petrol or diesel?
| Typical mileage | Passed first time, as tested | Passed first time, same mileage | |
|---|---|---|---|
| Petrol | 40,948 miles | 79 | 79 |
| Diesel | 49,847 miles | 77 | 79 |
Figures are in every 100 first tests. Petrol cars look better on the raw figures only because diesel cars have done more miles (typically 49,847 against 40,948). 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 29,000 | 39,000–48,000 | 61,000 and over | |
|---|---|---|---|
| Tyre condition (front) | 1.6 | 2.0 | 2.6 |
| Suspension arm ball joint (front) | 0.7 | 2.0 | 3.1 |
| Tyre tread depth (front) | 0.6 | 1.8 | 3.5 |
| Brake pads (front) | 1.1 | 1.7 | 1.9 |
| Brake light (rear) | 0.4 | 1.7 | 3.4 |
Faults per 100 first tests, by the car's mileage at the test.
When a car fails
of failed cars had one item to fix.
of failed cars had three or more items to fix.
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.
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.
