How reliable is the Mitsubishi Grandis compared with other cars?

We do not publish a comparison for the Mitsubishi Grandis, because the cars of this model that have been tested do not cover a wide enough range of ages and mileages.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 51.5% across 903 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 Mitsubishi Grandis?

The most common advisory is "Tyre tread depth not in accordance with the requirements", noted on 26.7% of all Mitsubishi Grandis tests. An advisory is not a failure: it flags something that will likely need attention before the next test.

What mileage does a Mitsubishi Grandis usually have at its MOT?

The average odometer reading recorded at test is 125,464 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 Mitsubishi Grandis models petrol or diesel?

Of the Mitsubishi Grandis cars tested, 57% are petrol, 43% are diesel. Fuel type affects which items tend to fail, particularly emissions and exhaust components.

Mitsubishi Grandis MOT pass rate & common failures

From 903 recorded MOT tests of the Mitsubishi Grandis, published by DVSA.

Data updated 29 July 2026

Quick answer

Across 903 MOT tests, 51.5% of Mitsubishi Grandis tests ended in a pass. This figure is not adjusted for age or mileage, so it is not a reliability ranking: the Mitsubishi Grandis 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 lamp missing, inoperative or in the case of a multiple light source more than 1/2 not functioning, which appears in 26.2% of failed tests. Cars of this model average 125,464 miles on the odometer when tested.

51.5%unadjusted, not comparable903 tests

We are not publishing a ranking for the Grandis. 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 903 tests and are worth reading on their own terms.

Most common advisories

Share of all Mitsubishi Grandis tests carrying each advisory. The denominator differs from the failure list above because an advisory can be issued on a car that passed.

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.
