How reliable is the Toyota Noah compared with other cars?

We do not publish a comparison for the Toyota Noah, because the cars of this model that have been tested do not cover a wide enough range of ages and mileages.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 85.2% across 1,134 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 Toyota Noah?

The most common advisory is "Tyre tread depth not in accordance with the requirements", noted on 11.0% of all Toyota Noah tests. An advisory is not a failure: it flags something that will likely need attention before the next test.

What mileage does a Toyota Noah usually have at its MOT?

The average odometer reading recorded at test is 74,510 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.

Does a Toyota Noah get harder to pass as it ages?

Yes. At 3 to 5 years old, 90.3% of Toyota Noah tests pass. By fifteen years or more, that falls to 62.4%. Nearly every model follows this pattern, which is why comparing raw pass rates between models is misleading unless age is accounted for.

Are most Toyota Noah models petrol or diesel?

Of the Toyota Noah cars tested, 64% are hybrid, 35% are petrol. Fuel type affects which items tend to fail, particularly emissions and exhaust components.

Toyota Noah MOT pass rate & common failures

From 1,134 recorded MOT tests of the Toyota Noah, published by DVSA.

Data updated 29 July 2026

Quick answer

Across 1,134 MOT tests, 85.2% of Toyota Noah tests ended in a pass. This figure is not adjusted for age or mileage, so it is not a reliability ranking: the Toyota Noah 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 joint dust cover missing or no longer prevents the ingress of dirt etc, which appears in 22.9% of failed tests. Cars of this model average 74,510 miles on the odometer when tested.

We are not publishing a ranking for the Noah. 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 1,134 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.
