Is the Allied getting worse?
The fail rate rose 4.9 points to 18.3% from 2022 to 2025 while the median one tested aged 2 years, which is about what ageing alone predicts (3.2 points). Read it as the fleet getting older rather than the model changing.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 2,462 | 4 | 13.4% | 22.5% | |
| 2023 | 3,407 | 4 | 15.2% | 22.8% | |
| 2024 | 3,301 | 5 | 19% | 23.2% | |
| 2025 | 3,616 | 6 | 18.3% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Allied at its test that year, and it is the number to watch: across the whole fleet each extra year of age adds roughly 1.9 points to the fail rate, so a model whose age and fail rate rise together is simply getting older.
The exact defects that fail it
Every failure item DVSA recorded against a Allied in 2025, counted by how many tests each one appeared on.
- 1Wipers: does not clear the windscreen effectively90 tests
- 2Joints: constant velocity boot split or insecure, no longer prevents the ingress of dirt55 tests
- 3Linkage pins and bushes: pin or bush excessively worn54 tests
- 4Brake pads: less than 1.5 mm thick52 tests
- 5Condition: has a cut in excess of the requirements deep enough to reach the ply or cords51 tests
- 6Tyre pressure monitoring system: malfunctioning or obviously inoperative44 tests
- 7Headlamp: not working on dipped beam40 tests
- 8Exhaust system: has a major leak of exhaust gases37 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical Allied collects 2.39 of them per test, and these are the ones that come up most. Treat it as the running-repairs list for the next year or two.
- 1Tread depth: tread depth below requirements of 1.6mm340 tests
- 2Condition: has a tear, caused by separation or partial failure of its structure311 tests
- 3Brake pads: less than 1.5 mm thick301 tests
- 4Rigid brake pipes: excessively corroded219 tests
- 5Brake discs: in such a condition that it is seriously weakened217 tests
- 6Pins and bushes: pin or bush excessively worn189 tests
- 7Linkage pins and bushes: pin or bush excessively worn163 tests
- 8Brake discs: significantly and obviously worn142 tests
Questions
What is the Ford Allied MOT pass rate?
81.8% of the 3,664 Ford Allied first-attempt MOTs in 2025 passed. The fail rate of 18.2% compares with 22.6% across all cars. A further 4.2% passed after a defect was fixed during the test visit.
What does a Ford Allied usually fail on?
The single most common failure is "Wipers: does not clear the windscreen effectively", recorded on 90 failed tests, followed by "Joints: constant velocity boot split or insecure, no longer prevents the ingress of dirt" and "Linkage pins and bushes: pin or bush excessively worn". By section, lamps, reflectors and electrical equipment appears in 23.8% of failures, tyres appears in 23.4% of failures, brakes appears in 23.1% of failures.
Does age change the odds?
Sharply. At 3 to 5 years old the fail rate was 17%; at 6-9 years it was 19%. The median Ford Allied tested in 2025 was 6 years old with 41,331 miles.
Is the Ford Allied getting less reliable?
The fail rate rose 4.9 points to 18.3% from 2022 to 2025 while the median one tested aged 2 years, which is about what ageing alone predicts (3.2 points). Read it as the fleet getting older rather than the model changing.
