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 2013 Toyota Hilux 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.
Body and structure
Two faults. The strongest is the chassis condition (rear): 69 times as often as on similar cars.
Figures below are measured across the 1,427 of 1,428 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.
Chassis condition (rear)
What it means
A main load-bearing structural member that is fractured, deformed, modified or inadequately repaired is Major when structural rigidity is significantly reduced, and Dangerous where steering or braking is likely to be adversely affected. Corrosion of the body, cab or chassis at a mounting point is Dangerous where overall security or stability is impaired.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 103 first tests, 32 times as often as on similar cars.
Chassis condition (front)
What it means
A main load-bearing structural member that is fractured, deformed, modified or inadequately repaired is Major when structural rigidity is significantly reduced, and Dangerous where steering or braking is likely to be adversely affected. Corrosion of the body, cab or chassis at a mounting point is Dangerous where overall security or stability is impaired.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 27 first tests, 22 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
Three faults. The strongest is the suspension spring mounting area (rear): 62 times as often as on similar cars.
Suspension spring mounting area (rear)
What it means
Testers check the strength and continuity of the load bearing structure within a set distance of a spring, sub-frame or suspension mounting, an area DVSA calls a prescribed area. Strength that is significantly reduced, or an area inadequately repaired, is Major. Structure so weakened that control of the vehicle is likely to be adversely affected is graded Dangerous.
Leaf spring (rear)
What it means
Modified spring anchor or shackle brackets with more mounting holes than the chassis are not a reason to reject leaf spring suspension, and neither is a missing bump stop rubber. A fractured main leaf is graded Dangerous. A spring that is fractured or seriously weakened is graded Major.
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.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 43 first tests, 5.9 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.
Brakes
Five faults. The strongest is the brake efficiency below minimum (roller test): 6.0 times as often as on similar cars.
Brake efficiency below minimum (roller test)
Brake imbalance across an axle (roller test, front)
What it means
An imbalance across an axle is measured against the maximum effort recorded from the other wheel on the same axle. It is disregarded if the lower effort is from a locked wheel, or if the higher effort from a wheel is no more than a small set figure. Less than a set share is Major, and less than half on a steered axle is Dangerous, but the rear axle check does not apply to tricycles or quadricycles.
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.
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 159 first tests, 3.2 times as often as on similar cars.
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 117 first tests, 3.5 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.
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.
Vehicle structure condition
Headlight (front)
Flexible brake hoses (front)
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
- 60in 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
- 33in every 100
- Did not pass, and were not fixed at the test station.
First-attempt pass 59.7% of 3,546 first tests (2025): only cars that passed first time count. Official-style pass 67.2%: cars fixed at the test station also count as a pass. The 7 fixed and the 33 not fixed make the 40 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, 62 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 2013 Hilux.
Of 2013 Hilux vehicles with under 74,000 miles, 67 in every 100 passed their 2025 MOT first time. With 144,000 miles or more, 54 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 74,000 | 96,000–116,000 | 144,000 and over | |
|---|---|---|---|
| Individual sidelight or tail light (front) | 1.7 | 8.6 | 12.6 |
| Handbrake efficiency below minimum (roller test) | 2.4 | 4.7 | 7.7 |
| Coil spring (front) | 3.9 | 3.5 | 4.3 |
| Chassis condition (rear) | 2.4 | 4.8 | 2.3 |
| Headlight aim | 1.9 | 3.2 | 4.1 |
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.
