How reliable is the Subaru Justy compared with other cars?

We do not publish a comparison for the Subaru Justy, because the cars of this model that have been tested do not cover a wide enough range of ages and mileages.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 62.1% across 586 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 is the most common MOT failure on a Subaru Justy?

The item recorded most often is "A suspension pin, bush or joint excessively worn", which appears in 30.0% of failed Subaru Justy tests. Because one failed test can list several items, these shares do not add up to 100%.

What do testers most often warn about on a Subaru Justy?

The most common advisory is "Brake pipe damaged or excessively corroded", noted on 32.1% of all Subaru Justy tests. An advisory is not a failure: it flags something that will likely need attention before the next test.

What mileage does a Subaru Justy usually have at its MOT?

The average odometer reading recorded at test is 71,446 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.

Subaru Justy MOT pass rate & common failures

From 586 recorded MOT tests of the Subaru Justy, published by DVSA.

Data updated 29 July 2026

Quick answer

Across 586 MOT tests, 62.1% of Subaru Justy tests ended in a pass. This figure is not adjusted for age or mileage, so it is not a reliability ranking: the Subaru Justy 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 suspension pin, bush or joint excessively worn, which appears in 30.0% of failed tests. Cars of this model average 71,446 miles on the odometer when tested.

Recorded pass rate

62.1%unadjusted, not comparable586 tests

We are not publishing a ranking for the Justy. 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 586 tests and are worth reading on their own terms.

Most common failure items

Share of failed Subaru Justy tests in which each item was recorded. One failed test often lists several items, so these do not sum to 100%.

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.
