How reliable is the Kia Sedona compared with other cars?

We do not publish a comparison for the Kia Sedona, because the cars of this model that have been tested do not cover a wide enough range of ages and mileages.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 55.2% across 4,106 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 Kia Sedona?

The most common advisory is "Tyre tread depth not in accordance with the requirements", noted on 28.4% of all Kia Sedona tests. An advisory is not a failure: it flags something that will likely need attention before the next test.

What mileage does a Kia Sedona usually have at its MOT?

The average odometer reading recorded at test is 99,488 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 Kia Sedona models petrol or diesel?

Of the Kia Sedona cars tested, 98% are diesel, 2% are petrol. Fuel type affects which items tend to fail, particularly emissions and exhaust components.

Kia Sedona MOT pass rate & common failures

From 4,106 recorded MOT tests of the Kia Sedona, published by DVSA.

Data updated 29 July 2026

Quick answer

Across 4,106 MOT tests, 55.2% of Kia Sedona tests ended in a pass. This figure is not adjusted for age or mileage, so it is not a reliability ranking: the Kia Sedona 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 14.4% of failed tests. Cars of this model average 99,488 miles on the odometer when tested.

We are not publishing a ranking for the Sedona. 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 4,106 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.
