Is the Fourtrak getting worse?
The fail rate fell 5.5 points to 28.5% from 2022 to 2025 while the median one tested aged 4 years, which is about what ageing alone predicts (-4.2 points). Read it as the fleet getting older rather than the model changing.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 1,688 | 24 | 34% | 22.5% | |
| 2023 | 1,459 | 25 | 33.7% | 22.8% | |
| 2024 | 1,187 | 26 | 32.8% | 23.2% | |
| 2025 | 1,095 | 28 | 28.5% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Fourtrak 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 Fourtrak in 2025, counted by how many tests each one appeared on.
- 1Prescribed areas: prescribed area strength or continuity significantly reduced70 tests
- 2Component mounting prescribed areas: prescribed area excessively corroded significantly reducing structural strength36 tests
- 3Rear fog lamp: not working36 tests
- 4Wipers: does not clear the windscreen effectively36 tests
- 5Joints: constant velocity boot split or insecure, no longer prevents the ingress of dirt34 tests
- 6Chassis condition: or chassis has excessive corrosion, seriously affecting its strength within 30cm of a body mounting31 tests
- 7Exhaust system: has a major leak of exhaust gases31 tests
- 8Ball joint: ball joint excessively worn28 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical Fourtrak collects 3.68 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.
- 1Engine oil leaks: leaking excessively from engine163 tests
- 2Rigid brake pipes: excessively corroded134 tests
- 3Wheel bearings: has excessive play109 tests
- 4Condition: has a tear, caused by separation or partial failure of its structure95 tests
- 5Pins and bushes: pin or bush excessively worn90 tests
- 6Chassis condition: corroded to the extent that the rigidity of the assembly is significantly reduced88 tests
- 7Integral vehicle structure condition: corroded to the extent that the rigidity of the assembly is significantly reduced73 tests
- 8Exhaust system: has a major leak of exhaust gases71 tests
Questions
What is the Daihatsu Fourtrak MOT pass rate?
71.5% of the 1,095 Daihatsu Fourtrak first-attempt MOTs in 2025 passed. The fail rate of 28.5% compares with 22.6% across all cars. A further 5.1% passed after a defect was fixed during the test visit.
What does a Daihatsu Fourtrak usually fail on?
The single most common failure is "Prescribed areas: prescribed area strength or continuity significantly reduced", recorded on 70 failed tests, followed by "Component mounting prescribed areas: prescribed area excessively corroded significantly reducing structural strength" and "Rear fog lamp: not working". By section, suspension appears in 51.6% of failures, lamps, reflectors and electrical equipment appears in 46.2% of failures, body, chassis, structure appears in 44.9% of failures.
Does age change the odds?
Sharply. At 3 to 5 years old the fail rate was n/a%; at 14+ years it was 28.5%. The median Daihatsu Fourtrak tested in 2025 was 28 years old with 117,501 miles.
Is the Daihatsu Fourtrak getting less reliable?
The fail rate fell 5.5 points to 28.5% from 2022 to 2025 while the median one tested aged 4 years, which is about what ageing alone predicts (-4.2 points). Read it as the fleet getting older rather than the model changing.
