How reliable is the Daihatsu Fourtrak compared with other cars?

We do not publish a comparison for the Daihatsu Fourtrak, because the cars of this model that have been tested do not cover a wide enough range of ages and mileages. Its raw pass rate is 66.6% across 1,157 tests, but comparing a raw rate between models mostly ranks them by how new they are rather than how good they are. The failure and advisory patterns further down the page are still drawn from real tests and are worth reading.

What do testers most often warn about on a Daihatsu Fourtrak?

The most common advisory is "Brake pipe damaged or excessively corroded", noted on 15.3% of all Daihatsu Fourtrak tests. An advisory is not a failure: it flags something that will likely need attention before the next test.

What mileage does a Daihatsu Fourtrak usually have at its MOT?

The average odometer reading recorded at test is 117,224 miles. This is the mileage across all tested examples of every age, not an annual figure, so treat it as a description of the fleet rather than a target for one car.

Are most Daihatsu Fourtrak models petrol or diesel?

Of the Daihatsu Fourtrak cars tested, 99% are diesel, 1% are petrol. Fuel type affects which items tend to fail, particularly emissions and exhaust components.

Model reliability file

Daihatsu Fourtrak MOT pass rate & common failures

From 1,157 recorded MOT tests of the Daihatsu Fourtrak, published by DVSA.

Data updated 29 July 2026

Quick answer

Across 1,157 MOT tests, 66.6% of Daihatsu Fourtrak tests ended in a pass. This figure is not adjusted for age or mileage, so it is not a reliability ranking: the Daihatsu Fourtrak fleet does not yet cover a wide enough spread of ages and distances to compare it fairly against other models. Its most commonly recorded failure is strength or continuity of the load bearing structure within 30cm of any seat belt anchorage (a 'prescribed area') is significantly reduced or inadequately repaired, which appears in 37.9% of failed tests. Cars of this model average 117,224 miles on the odometer when tested.

We are not publishing a ranking for the Fourtrak. The examples tested do not cover a wide enough spread of ages and mileages to compare it fairly, and an unadjusted pass rate mostly sorts models by how recently they were bought rather than how well they were built. The failure and advisory patterns below come from the same 1,157 tests and are worth reading on their own terms.

How this was worked out

Method and limits

Figures come from the DVSA anonymised MOT testing dataset, published under the Open Government Licence. Only class 4 initial tests are counted: retests are excluded so a car appears once, and abandoned tests are excluded entirely. No adjusted rate is shown because this model's tested examples do not cover enough of the national age and mileage range for standardisation to mean anything.

An MOT measures whether a car met a legal standard on the day. It is not a breakdown record, a service history or a running-cost estimate, and a pass rate is a property of a fleet rather than a prediction about one car.
