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 2011 Honda Jazz 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.
Brakes
One fault and two wear patterns. The strongest is the brake pads (rear): 3.3 times as often as on similar cars.
Figures below are measured across the 5,288 of 5,294 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.
Brake pads (rear)
What it means
A pad worn down to its wear indicator, or contaminated with oil or grease, is Major. A pad worn below the set thickness limit, missing or incorrectly mounted is Dangerous. The manual treats an illuminated brake wear indicator as no reason for failure, although DVSA also lists an illuminated indicator as a Major row.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 442 first tests, 2.4 times as often as on similar cars.
Brake discs (rear)
What it means
A brake disc or drum must be significantly worn before it is rejected, and being worn below the manufacturer's recommended limits is not a reason in itself. Significantly and obviously worn is Major, as is contamination with oil or grease. A disc or drum that is fractured, insecure, seriously weakened or missing is graded Dangerous.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 765 first tests, 2.3 times as often as on similar cars.
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.
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
Three faults. The strongest is the anti-roll bar linkage ball joint dust cover (front): 2.5 times as often as on similar cars.
Anti-roll bar linkage ball joint dust cover (front)
What it means
A suspension joint dust cover that is severely deteriorated is Minor. It becomes Major once it is missing or no longer prevents the ingress of dirt, so what matters is whether it still keeps dirt out. DVSA words this for any suspension joint dust cover, and files it here under anti-roll bars.
Anti-roll bar ball joint dust cover (front)
Suspension mounting area (rear)
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.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.
Lamps and electrical
One fault: individual sidelight or tail light (front), 2.0 times as often as on similar cars.
Individual sidelight or tail light (front)
What it means
A position lamp showing red light to the front or white light to the rear is Major. Rear lamps must show a steady red light, and front ones can show white, predominantly white with a blue tinge, or yellow if combined in a yellow headlamp. With a multiple light source, up to half not working is Minor and more than half is Major.
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.
Anti-roll bar (front)
Brake pedal
Headlight (front)
Suspension arm (front)
Brake performance (plate test, rear)
Flexible brake hoses
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
- 73in 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
- 20in every 100
- Did not pass, and were not fixed at the test station.
First-attempt pass 72.8% of 19,446 first tests (2025): only cars that passed first time count. Official-style pass 80.2%: cars fixed at the test station also count as a pass. The 7 fixed and the 20 not fixed make the 27 in every 100 that did not pass first time.
By fuel type
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, 74 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 2011 Jazz.
Of 2011 Jazz vehicles with under 47,000 miles, 83 in every 100 passed their 2025 MOT first time. With 99,000 miles or more, 62 in every 100 did.
Which fuel?
| Typical mileage | Passed first time, as tested | Passed first time, same mileage | |
|---|---|---|---|
| Petrol | 70,447 miles | 73 | 73 |
| Hybrid | 64,921 miles | 77 | 77 |
Figures are in every 100 first tests. Hybrid cars look better on the raw figures only because petrol cars have done more miles (typically 70,447 against 64,921). At the same mileage there is no clear difference between the two.
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 47,000 | 63,000–78,000 | 99,000 and over | |
|---|---|---|---|
| Individual sidelight or tail light (front) | 0.8 | 5.0 | 11.6 |
| Anti-roll bar linkage ball joint dust cover (front) | 2.0 | 2.3 | 3.2 |
| Brake pads (rear) | 1.1 | 2.3 | 3.0 |
| Tyre condition (front) | 2.2 | 1.6 | 2.3 |
| Headlight aim | 1.1 | 1.4 | 2.4 |
Faults per 100 first tests, by the car's mileage at the test.

of failed cars had three or more items to fix.
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.
