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 Kia Ceed vehicles in 2025, not a prediction that any one car will have them. Faults are grouped by part of the car. A wear pattern follows age and use more than the way the car was built. They come from MOT defect codes, not manufacturer bulletins, recalls or a diagnosis of any one car.
Brakes
Two faults. The strongest is the brake performance (roller test, front): 6.2 times as often as on similar cars.
Figures below are measured across the 3,134 of 3,137 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.
Brake performance (roller test, front)
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 156 first tests, 3.8 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
Two faults. The strongest is the suspension arm pins and bushes (rear): 5.7 times as often as on similar cars.
Suspension arm pins and bushes (rear)
What it means
Pins and bushes on suspension arms fail as Major when they are excessively worn. They are graded Dangerous when likely to become detached. DVSA uses the same wording for a suspension joint.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 264 first tests, 7.4 times as often as on similar cars.
Suspension arm pins and bushes (front)
What it means
Pins and bushes on suspension arms fail as Major when they are excessively worn. They are graded Dangerous when likely to become detached. DVSA uses the same wording for a suspension joint.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage. Advisories count notes recorded on failed first tests only.
Lamps and electrical
One fault and one wear pattern. The strongest is the rear fog light: 2.9 times as often as on similar cars.
Rear fog light
What it means
A missing obligatory rear fog lamp, one that is not working, or one that does not emit a steady red light is graded Major. A rear fog lamp adversely affected by the operation of any other lamp is Major too. The manual allows it to go out when main beam is switched on or when dipped beam headlamps are switched off.
Headlight aim not tested
What it means
Headlamp aim recorded as not tested, or unable to be tested, is a Major failure. These results must only be used where it becomes apparent during the test that the item cannot be tested, and this could not have been identified before starting. The reason must be included in the additional information box.
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.
Brake performance (plate test, front)
Suspension arm (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
- 71in 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
- 24in every 100
- Did not pass, and were not fixed at the test station.
First-attempt pass 70.7% of 10,689 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 5 fixed and the 24 not fixed make the 29 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, 72 in every 100 passed first time.
| Year | Passed first time | First tests |
|---|---|---|
| 2007 | 50 in every 100 | 1,903 |
| 2008 | 48 in every 100 | 3,559 |
| 2009 | 51 in every 100 | 5,789 |

If you are buying one
What this year's MOT record means for the decision in front of you.
Mileage matters most on a 2015 Ceed.
Of 2015 Ceed vehicles with under 54,000 miles, 79 in every 100 passed their 2025 MOT first time. With 106,000 miles or more, 64 in every 100 did.
Petrol or diesel?
| Typical mileage | Passed first time, as tested | Passed first time, same mileage | |
|---|---|---|---|
| Diesel | 85,540 miles | 69 | 70 |
| Petrol | 67,576 miles | 73 | 71 |
Figures are in every 100 first tests. Petrol cars look better on the raw figures only because diesel cars have done more miles (typically 85,540 against 67,576). 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 54,000 | 71,000–86,000 | 106,000 and over | |
|---|---|---|---|
| Suspension arm pins and bushes (front) | 3.3 | 4.3 | 4.6 |
| Handbrake efficiency below minimum (roller test) | 1.2 | 3.0 | 4.5 |
| Brake performance (roller test, front) | 2.5 | 2.2 | 1.9 |
| Tyre tread depth (front) | 1.0 | 2.1 | 3.1 |
| Windscreen washers | 1.2 | 2.2 | 2.3 |
Faults per 100 first tests, by the car's mileage at the test.

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.

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.
