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 2007 Vauxhall Corsa 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.
Suspension
Four faults. The strongest is the suspension sub-frame (front): 7.3 times as often as on similar cars.
Figures below are measured across the 12,334 of 12,349 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.
Suspension sub-frame (front)
What it means
A suspension sub-frame insecurely attached to the chassis or axle is Major, and Dangerous when it is insecure and impairing directional stability. A sub-frame that is missing, likely to become detached, fractured or likely to fail is also Dangerous. Excessive damage or corrosion that seriously weakens it is Major.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 1,034 first tests, 2.3 times as often as on similar cars.
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 (rear)
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.
Coil spring (rear)
What it means
A missing bump stop rubber is not a reason to fail a coil spring. When the vehicle is jacked and lowered, a spring that does not correctly locate as the suspension returns to its normal running position is rejected as insecurely attached. A missing spring is Major, and graded Dangerous where directional control is affected.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage. Advisories count notes recorded on failed first tests only.
Noise, emissions and leaks
One fault: engine oil leaks, 4.8 times as often as on similar cars.
Engine oil leaks
What it means
Leaks of engine coolant, screen wash and the fluid used for selective catalyst reduction are not reasons for failure. Excessive leaking from the engine that is likely to harm the environment or to pose a safety risk to other road users is Major. Continuous leaking likely to pose a serious risk to road safety is graded Dangerous.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 3,408 first tests, 2.3 times as often as on similar cars.

Tyres
Two wear patterns. The strongest is the tyre size or type (front): 3.8 times as often as on similar cars.
Tyre size or type (front)
What it means
Tyres of different sizes or different aspect ratios on the same axle, or on twin wheels, are graded Major, as are tyres of different structure on the same axle, such as radial-ply and cross-ply. Steel and fabric radial-ply count as the same structure. The manual treats a standard car tyre and one of a single stated lower aspect ratio as almost identical in size, so that pair is allowed in any mix.

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
- 52in every 100
- Passed on the first test.
- Fixed at the station
- 11in every 100
- Failed, then fixed at the test station the same day.
- Failed
- 37in every 100
- Did not pass, and were not fixed at the test station.
First-attempt pass 51.9% of 25,689 first tests (2025): only cars that passed first time count. Official-style pass 62.9%: cars fixed at the test station also count as a pass. The 11 fixed and the 37 not fixed make the 48 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.

If you are buying one
What this year's MOT record means for the decision in front of you.
Mileage matters most on a 2007 Corsa.
Of 2007 Corsa vehicles with under 64,000 miles, 62 in every 100 passed their 2025 MOT first time. With 117,000 miles or more, 47 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 64,000 | 82,000–98,000 | 117,000 and over | |
|---|---|---|---|
| Individual sidelight or tail light (front) | 1.6 | 6.7 | 10.4 |
| Coil spring (front) | 5.0 | 5.1 | 4.7 |
| Windscreen washers | 3.2 | 5.0 | 5.9 |
| Petrol engine warning light | 2.5 | 3.3 | 4.6 |
| Headlight aim | 2.1 | 4.1 | 4.9 |

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.
