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 Vauxhall Vivaro 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
Four faults. The strongest is the brake efficiency below minimum (roller test): 5.4 times as often as on similar cars.
Figures below are measured across the 314 of 317 failed first attempts (99.1%) 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 efficiency below minimum (roller test)
Brake performance (roller test, front)
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.
Brake performance (roller test, rear)
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.
Suspension
Three faults. The strongest is the anti-roll bar linkage ball joints (front): 4.1 times as often as on similar cars.
Anti-roll bar linkage ball joints (front)
What it means
Excessive wear on an anti-roll bar linkage ball joint is Major. A joint likely to become detached is graded Dangerous.
Suspension mounting area (front)
What it means
The load bearing structure within a set distance of a sub-frame, spring or suspension component mounting is a prescribed area. Major applies when its strength or continuity is significantly reduced or it is inadequately repaired. Dangerous applies when it is so weakened that control of the vehicle is likely to be adversely affected.
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.
Visibility
One fault: windscreen washers, 2.7 times as often as on similar cars.
Windscreen washers
What it means
Windscreen washers that are not working, or do not provide sufficient fluid to clear the windscreen, are graded Major. They must provide enough fluid for the wipers to clear the windscreen effectively. Vehicles with an opening windscreen, or some other adequate view to the front, left and right, are not inspected for washers.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.
Seat belts and restraints
One fault: airbag warning light, 2.3 times as often as on similar cars.
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.
Lamps and electrical
One fault: number plate lights, 2.1 times as often as on similar cars.
Number plate lights
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.
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.
Shock absorbers (front)
Non-component advisories
Brake discs (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
- 45in 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
- 47in every 100
- Did not pass, and were not fixed at the test station.
First-attempt pass 44.9% of 575 first tests (2025): only cars that passed first time count. Official-style pass 52.9%: cars fixed at the test station also count as a pass. The 8 fixed and the 47 not fixed make the 55 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, 47 in every 100 passed first time.

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.
