Common faults
Failure patterns that show up more often on this registration year than on similar cars of the same class, age, and mileage.
Standout: Brake light (rear), 11.5% of this year's failed first attempts
Recorded on 344 of those tests. That is about 4.0 times as often as on similar cars of the same age and mileage. It is also the most common failure on this year. The full ranked list is in the table below.
No fault was sharply out of line for this year. These are the largest differences from similar cars.
Shares below are measured across the 2,984 of 2,987 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 table.
Wear patterns
Usage and mileage effects that often track road use rather than model design.
These patterns look like wear or usage effects rather than model-specific design faults. Tyres, brake friction material, and alignment-related defects often track mileage and road use.

MOT pass rates
How first tests ended, and how the pass rates are counted.
Summary
Of every 100 first tests, 79 passed first time and 7 more were fixed at the test station. The other 14 failed.
How 100 first tests ended
First-attempt pass 78.8% of 14,103 first tests (2025). Only cars that passed first time count.
Official-style pass 85.6%. Cars fixed at the station count as a pass.
Did not pass, and were not fixed at the test station.
By fuel type
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 yearsPassed 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 2016 Auris.
Of 2016 Auris with under 42,000 miles, 88 in every 100 passed their 2025 MOT first time. With 123,000 miles or more, 73 in every 100 did.
Which fuel?
| Typical mileage | Passed first time, as tested | Passed first time, same mileage | |
|---|---|---|---|
| Hybrid | 74,855 miles | 78 | 79 |
| Petrol | 52,516 miles | 82 | 78 |
Figures are in every 100 first tests. Petrol cars look better on the raw figures only because hybrid cars have done more miles (typically 74,855 against 52,516). 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 42,000 | 59,000–79,000 | 123,000 and over | |
|---|---|---|---|
| Brake light (rear) | 1.3 | 2.7 | 2.8 |
| Tyre condition (rear) | 1.5 | 1.6 | 1.4 |
| Handbrake efficiency below minimum (roller test) | 0.4 | 1.6 | 2.2 |
| Headlight aim | 0.9 | 1.2 | 1.8 |
| Headlight (front) | 0.1 | 1.5 | 2.2 |
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.

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.
