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 2015 Ford Ranger 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.
Suspension
Two faults. The strongest is the leaf spring (rear): 117 times as often as on similar cars.
Figures below are measured across the 2,018 of 2,021 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.
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.
Coil spring (front)
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.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 56 first tests, 3.6 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
Three faults. The strongest is the anti-lock braking system (ABS): 7.9 times as often as on similar cars.
Anti-lock braking system (ABS)
What it means
ABS is failed as removed only where it has obviously been removed, because not every vehicle in the age range where removal is not permitted has ABS. A warning lamp that does not light or shows an ABS fault is Major, as is a missing or excessively damaged wheel speed sensor. Every failure row for this component is Major.
Electronic stability control
What it means
An ESC warning lamp is failed only when the tester is certain it indicates an ESC malfunction, because the lamp takes various forms and the owner's handbook may need checking. The system is also called ESP, VDC or DSC, among many other names. Every failure row is Major, covering the lamp, wheel speed sensors, wiring, other components and the switch.
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 124 first tests, 3.8 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.
Lamps and electrical
Two faults and one wear pattern. The strongest is the headlight aim not tested (front): 5.2 times as often as on similar cars.
Headlight aim not tested (front)
What it means
Headlamp aim recorded as not tested, or unable to be tested, is a Major failure. These results must only be used where it becomes apparent during the test that the item cannot be tested, and this could not have been identified before starting. The reason must be included in the additional information box.
Headlight (front)
What it means
On vehicles first used on or after a set date, a halogen headlamp unit converted to take HID or LED bulbs fails for light source and lamp not compatible, which is Major. A complete unit built with those light sources is not failed for that. The precise position of the lamps is not part of the inspection beyond a visual look to see that they sit at about the same height and distance from each side.
Rear fog light
What it means
A missing obligatory rear fog lamp, one that is not working, or one that does not emit a steady red light is graded Major. A rear fog lamp adversely affected by the operation of any other lamp is Major too. The manual allows it to go out when main beam is switched on or when dipped beam headlamps are switched off.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.
Noise, emissions and leaks
Two faults. The strongest is the diesel emissions test (compression-ignition rules for vehicles from 01/01/2014): 5.0 times as often as on similar cars.
Diesel emissions test (compression-ignition rules for vehicles from 01/01/2014)
Diesel engine warning light
What it means
An engine malfunction indicator lamp that is illuminated to show a malfunction is graded Major on a diesel, but only on the diesels the test covers, which depends on the vehicle type and when it was first used. DVSA lists it under exhaust emissions for compression ignition engines, and the detail line for the row also names an inoperative lamp.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.
Body and structure
One fault: exhaust system, 2.6 times as often as on similar cars.
Exhaust system
What it means
Exhaust fumes causing a danger to health of persons on board are graded Dangerous, and so is a silencer likely to become detached. Fumes entering the cabin are Major. One or more missing or defective mountings does not necessarily make the exhaust insecure, since testers assess the overall security of the system.
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.
Chassis condition
Brake light
Transmission oil leaks (front)
Suspension arm (front)
Track rod end (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
- 64in 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
- 29in every 100
- Did not pass, and were not fixed at the test station.
First-attempt pass 64.4% of 5,675 first tests (2025): only cars that passed first time count. Official-style pass 71.4%: cars fixed at the test station also count as a pass. The 7 fixed and the 29 not fixed make the 36 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, 66 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 2015 Ford Ranger.
Of 2015 Ford Ranger vehicles with under 67,000 miles, 73 in every 100 passed their 2025 MOT first time. With 124,000 miles or more, 61 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 67,000 | 85,000–102,000 | 124,000 and over | |
|---|---|---|---|
| Coil spring (front) | 4.8 | 5.0 | 5.2 |
| Headlight | 2.4 | 5.6 | 5.0 |
| Diesel engine warning light | 1.8 | 3.6 | 4.0 |
| Anti-lock braking system (ABS) | 1.4 | 2.8 | 4.3 |
| Track rod end (front) | 1.2 | 3.2 | 5.0 |

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.
