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 2002 Renault Clio 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 hazard warning switch: 15 times as often as on similar cars.
Figures below are measured across the 1,107 of 1,111 failed first attempts (99.6%) 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.
Hazard warning switch
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.
Steering
One fault: steering rack (front), 7.2 times as often as on similar cars.
Steering rack (front)
What it means
Steering gear casing retaining devices dangerously loose, or visible relative movement to the chassis or bodywork, is graded Dangerous. A casing not properly attached, or fractured, is Major, but a fracture that affects the stability or attachment of the casing is Dangerous. A gaiter damaged but still keeping dirt out is Minor, and Major once missing or no longer doing so.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.
Seat belts and restraints
Two faults. The strongest is the seat belt condition (rear): 5.8 times as often as on similar cars.
Seat belt condition (rear)
Airbag warning light
What it means
The airbag warning lamp (SRS MIL in DVSA's wording) is failed only if it indicates a system malfunction, which is Major. A lamp lit to show the passenger airbag is disabled is not to be regarded as a defect. Dashboard messages are not a defect in their own right, though they can help the tester confirm a malfunction.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.
Suspension
Five faults. The strongest is the anti-roll bar linkage pins and bushes (front): 5.6 times as often as on similar cars.
Anti-roll bar linkage pins and bushes (front)
What it means
Excessive wear in an anti-roll bar linkage pin or bush is Major. If the pin or bush is likely to become detached, it is graded Dangerous. The wording is DVSA's general one for a suspension pin, bush or joint.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 133 first tests, 7.0 times as often as on similar cars.
Wheel bearings (rear)
Macpherson strut (front)
What it means
Many MacPherson strut top bushes are designed to have significant lateral play when the suspension hangs free, so a top bush is rejected only when the play comes from wear or maladjustment. A top bush or bearing with excessive wear or free play is Major. Rubber or synthetic bushes are rejected only for serious deterioration of the bonding or flexible material.
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.
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.

MOT pass rates
How first tests ended, and how the pass rates are counted.
- Passed first time
- 54in 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
- 39in every 100
- Did not pass, and were not fixed at the test station.
First-attempt pass 54.3% of 2,429 first tests (2025): only cars that passed first time count. Official-style pass 61.5%: cars fixed at the test station also count as a pass. The 7 fixed and the 39 not fixed make the 46 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, 52 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 2002 Clio.
Of 2002 Clio vehicles with under 52,000 miles, 65 in every 100 passed their 2025 MOT first time. With 113,000 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 52,000 | 72,000–92,000 | 113,000 and over | |
|---|---|---|---|
| Airbag warning light | 4.2 | 5.6 | 4.0 |
| Number plate lights | 1.0 | 4.6 | 5.1 |
| Headlight | 3.6 | 5.8 | 3.4 |
| Drive shaft joints and boots (front) | 2.1 | 3.8 | 6.3 |
| Headlight aim | 2.7 | 4.6 | 5.1 |

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.
