How reliable is the Maserati Quattroporte compared with other cars?

We do not publish a comparison for the Maserati Quattroporte, because the cars of this model that have been tested do not cover a wide enough range of ages and mileages.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 79.6% across 1,254 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 Maserati Quattroporte?

The item recorded most often is "Tyre tread depth not in accordance with the requirements", which appears in 13.8% of failed Maserati Quattroporte 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 Maserati Quattroporte?

The most common advisory is "Tyre tread depth not in accordance with the requirements", noted on 21.3% of all Maserati Quattroporte tests. An advisory is not a failure: it flags something that will likely need attention before the next test.

What mileage does a Maserati Quattroporte usually have at its MOT?

The average odometer reading recorded at test is 62,521 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 Maserati Quattroporte get harder to pass as it ages?

Yes. At 6 to 8 years old, 85.1% of Maserati Quattroporte tests pass. By fifteen years or more, that falls to 75.2%. Nearly every model follows this pattern, which is why comparing raw pass rates between models is misleading unless age is accounted for.

Are most Maserati Quattroporte models petrol or diesel?

Of the Maserati Quattroporte cars tested, 72% are petrol, 28% are diesel. Fuel type affects which items tend to fail, particularly emissions and exhaust components.

Model reliability file

Maserati Quattroporte MOT pass rate & common failures

From 1,254 recorded MOT tests of the Maserati Quattroporte, published by DVSA.

Data updated 29 July 2026

Quick answer

Across 1,254 MOT tests, 79.6% of Maserati Quattroporte tests ended in a pass. This figure is not adjusted for age or mileage, so it is not a reliability ranking: the Maserati Quattroporte 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 tyre tread depth not in accordance with the requirements, which appears in 13.8% of failed tests. Cars of this model average 62,521 miles on the odometer when tested.

We are not publishing a ranking for the Quattroporte. 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 1,254 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.
