Is the Porsche Panamera reliable?

On MOT evidence the Porsche Panamera is well above average. It passes 87.8% of tests once age and mileage are accounted for, against a national average of 72.3%. That figure covers 84% of the national age and mileage range, which is enough to quote but not to rank. This measures how often the car meets the MOT standard, not how often it breaks down or what a repair costs.

What is the most common MOT failure on a Porsche Panamera?

The item recorded most often is "A tyre cords visible or damaged", which appears in 22.5% of failed Porsche Panamera 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 Porsche Panamera?

The most common advisory is "Tyre tread depth not in accordance with the requirements", noted on 24.6% of all Porsche Panamera tests. An advisory is not a failure: it flags something that will likely need attention before the next test.

What mileage does a Porsche Panamera usually have at its MOT?

The average odometer reading recorded at test is 66,558 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 Porsche Panamera get harder to pass as it ages?

Yes. At 3 to 5 years old, 90.4% of Porsche Panamera tests pass. By fifteen years or more, that falls to 87.0%. Nearly every model follows this pattern, which is why comparing raw pass rates between models is misleading unless age is accounted for.

Are most Porsche Panamera models petrol or diesel?

Of the Porsche Panamera cars tested, 36% are petrol, 32% are hybrid, 32% are diesel. Fuel type affects which items tend to fail, particularly emissions and exhaust components.

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. The adjusted rate is directly standardised across twenty-five age and mileage bands and reweighted onto the national distribution, so this model is compared against cars that have lived a similar life rather than against a younger or lighter-used fleet.

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.
