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 2010 Vauxhall Meriva 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.
Brakes
Three faults. The strongest is the rigid brake pipes (front): 4.8 times as often as on similar cars.
Figures below are measured across the 3,442 of 3,479 failed first attempts (98.9%) 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.
Rigid brake pipes (front)
What it means
Chafing, corrosion or damage to a rigid brake pipe justifies rejection once its wall thickness is reduced by a set amount, although DVSA accepts this is not easy to determine. If a tester is not sure, the benefit of the doubt applies. A leaking pipe or connection is graded Dangerous on a hydraulic system and Major on an air system.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 295 first tests, 3.2 times as often as on similar cars.
Flexible brake hoses (front)
What it means
Testers reject a flexible brake hose for being excessively damaged or chafed only if it is severe enough to expose the reinforcement. Slight damage, chafing or twisting is graded Minor. A leak is graded Dangerous on a hydraulic braking system and Major on an air system, and a hose damaged and likely to fail is also Dangerous.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 100 first tests, 3.3 times as often as on similar cars.
Rigid brake pipes (rear)
What it means
Chafing, corrosion or damage to a rigid brake pipe justifies rejection once its wall thickness is reduced by a set amount, although DVSA accepts this is not easy to determine. If a tester is not sure, the benefit of the doubt applies. A leaking pipe or connection is graded Dangerous on a hydraulic system and Major on an air system.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 360 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.
Suspension
Two faults. The strongest is the suspension sub-frame (front): 4.5 times as often as on similar cars.
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.
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.
Noise, emissions and leaks
One fault: petrol engine warning light, 2.3 times as often as on similar cars.
Petrol engine warning light
What it means
The malfunction indicator lamp (MIL) on a petrol engine is a Major failure when it is illuminated indicating a malfunction. The detail line DVSA gives for the same row also names an inoperative lamp. The test covers only certain petrol vehicles, depending on their age, size and fuel type.
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.

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
- 56in every 100
- Passed on the first test.
- Fixed at the station
- 8in every 100
- Failed, then fixed at the test station the same day.
- Failed
- 36in every 100
- Did not pass, and were not fixed at the test station.
First-attempt pass 56.1% of 7,921 first tests (2025): only cars that passed first time count. Official-style pass 63.7%: cars fixed at the test station also count as a pass. The 8 fixed and the 36 not fixed make the 44 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, 57 in every 100 passed first time.
| Year | Passed first time | First tests |
|---|---|---|
| 2004 | 46 in every 100 | 1,166 |
| 2005 | 45 in every 100 | 1,637 |
| 2006 | 47 in every 100 | 2,751 |

If you are buying one
What this year's MOT record means for the decision in front of you.
Mileage matters most on a 2010 Meriva.
Of 2010 Meriva vehicles with under 62,000 miles, 65 in every 100 passed their 2025 MOT first time. With 109,000 miles or more, 48 in every 100 did.
Petrol or diesel?
| Typical mileage | Passed first time, as tested | Passed first time, same mileage | |
|---|---|---|---|
| Petrol | 83,897 miles | 56 | 55 |
| Diesel | 90,858 miles | 60 | 61 |
Figures are in every 100 first tests. At the same mileage, diesel passed more often (61 against 55 in every 100).
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 62,000 | 78,000–92,000 | 109,000 and over | |
|---|---|---|---|
| Coil spring (rear) | 6.3 | 5.7 | 5.2 |
| Tyre condition (front) | 3.0 | 3.6 | 6.2 |
| Headlight aim | 1.6 | 3.8 | 4.3 |
| Petrol engine warning light | 2.1 | 2.4 | 4.6 |
| Windscreen washers | 1.8 | 2.3 | 3.6 |
Faults per 100 first tests, by the car's mileage at the test.

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.
