Is the Kia Sorento reliable?

On MOT evidence the Kia Sorento is about average. It passes 72.2% of tests once age and mileage are accounted for, against a national average of 72.3%, which ranks it 146 of 262 models with enough data for a fair comparison. 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 Kia Sorento?

The item recorded most often is "A steering ball joint with excessive wear or free play", which appears in 13.9% of failed Kia Sorento 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 Kia Sorento?

The most common advisory is "Tyre tread depth not in accordance with the requirements", noted on 28.8% of all Kia Sorento tests. An advisory is not a failure: it flags something that will likely need attention before the next test.

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

The average odometer reading recorded at test is 80,749 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.

Which Kia Sorento years are the most reliable?

Going by MOT pass rate, Kia Sorento cars first registered 2020–2022 do best at 86.4%, and those registered 2010 and earlier do worst at 54.9%. But that ordering is mostly age, not build year: almost every model passes less often as it wears, so the newest cars top this list whatever they are. A specific year looking strong here means little on its own; the failure items above, and the individual car's own MOT history, tell you far more.

Does a Kia Sorento get harder to pass as it ages?

Yes. At 3 to 5 years old, 86.4% of Kia Sorento tests pass. By fifteen years or more, that falls to 54.9%. Nearly every model follows this pattern, which is why comparing raw pass rates between models is misleading unless age is accounted for.

Are most Kia Sorento models petrol or diesel?

Of the Kia Sorento cars tested, 87% are diesel, 13% are hybrid. Fuel type affects which items tend to fail, particularly emissions and exhaust components.

From 36,320 recorded MOT tests of the Kia Sorento, published by DVSA.

Data updated 29 July 2026

Quick answer

The Kia Sorento passes 72.2% of MOT tests once results are adjusted for the age and mileage of the cars tested, against a national average of 72.3%. That is about average, ranking it 146 of 262 models with enough data to compare fairly. Based on 36,320 tests. Its most commonly recorded failure is steering ball joint with excessive wear or free play, which appears in 13.9% of failed tests. Cars of this model average 80,749 miles on the odometer when tested.

Kia Sorento common problems, by part and by year

The same failure record read the way a buyer asks the question: which parts wear out on a Sorento, when they start, and how each registration year compares — including the steps that mark a generation change.

Sorento common problems and results by year

How wear changes the picture

Sorento pass rate by age and registration year

How often the Kia Sorento passes at each age, with the years those cars were first registered. Tests are from 2025, so a car aged 3 to 5 was first used in 2020–2022.

3–5 yrsreg. 2020–202286%

6–8 yrsreg. 2017–201981%

9–11 yrsreg. 2014–201671%

12–14 yrsreg. 2011–201359%

15+ yrsreg. 2010 and earlier55%

Read this as an age curve rather than a verdict on particular model years. Nearly every car passes less often as it gets older, so a newer Sorento outscoring an older one says more about wear than about how that year’s cars were built. Bands holding too few tests to be meaningful are omitted rather than shown as a rate.

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.
