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 2014 SEAT Ibiza 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: 4.7 times as often as on similar cars.
Figures below are measured across the 7,133 failed first attempts in 2025 that had a mileage recorded, which allows a like-for-like comparison.
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.
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.
Brakes
Four faults. The strongest is the handbrake lever: 4.0 times as often as on similar cars.
Handbrake lever
Brake imbalance across an axle (roller test, efficiency check, rear)
What it means
A wheel giving less than a set share of the maximum effort from the other wheel on the same axle is Major. On a steered axle, less than half is graded Dangerous. Testers disregard an imbalance if the lower effort is the result of a locked wheel, or if the higher effort from a wheel is at or below a low set figure.
Brake performance (roller test, rear)
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 333 first tests, 2.2 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
Two faults. The strongest is the suspension arm pins and bushes (front): 3.6 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.
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 1,130 first tests, 4.7 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.
Body and structure
One fault: exhaust system, 2.4 times as often as on similar cars.
Exhaust system
What it means
Exhaust fumes causing a danger to health of persons on board are graded Dangerous, and so is a silencer likely to become detached. Fumes entering the cabin are Major. One or more missing or defective mountings does not necessarily make the exhaust insecure, since testers assess the overall security of the system.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 322 first tests, 2.4 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.
Power steering pipes and hoses (front)
Steering drag link end (front)
Steering ball joint (front)
Brake light (rear)
Steering rack play
Non-component advisories (front)
Brake imbalance across an axle (roller 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
- 61in every 100
- Passed on the first test.
- Fixed at the station
- 7in every 100
- Failed, then fixed at the test station the same day.
- Failed
- 32in every 100
- Did not pass, and were not fixed at the test station.
First-attempt pass 61.0% of 18,296 first tests (2025): only cars that passed first time count. Official-style pass 68.4%: cars fixed at the test station also count as a pass. The 7 fixed and the 32 not fixed make the 39 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, 62 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 matters most on a 2014 Ibiza.
Of 2014 Ibiza vehicles with under 56,000 miles, 74 in every 100 passed their 2025 MOT first time. With 101,000 miles or more, 52 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 56,000 | 71,000–84,000 | 101,000 and over | |
|---|---|---|---|
| Suspension arm pins and bushes (front) | 4.4 | 7.1 | 6.5 |
| Headlight aim | 1.3 | 3.5 | 4.0 |
| Windscreen washers | 1.7 | 3.6 | 4.1 |
| Tyre condition (front) | 2.3 | 3.0 | 3.6 |
| Handbrake efficiency below minimum (roller test) | 0.7 | 3.0 | 5.4 |

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.
