Is the BMW X6 reliable?

On MOT evidence the BMW X6 is well above average. It passes 82.9% of tests once age and mileage are accounted for, against a national average of 72.3%, which ranks it 30 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 BMW X6?

The item recorded most often is "A tyre seriously damaged", which appears in 20.8% of failed BMW X6 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 BMW X6?

The most common advisory is "Tyre tread depth not in accordance with the requirements", noted on 25.3% of all BMW X6 tests. An advisory is not a failure: it flags something that will likely need attention before the next test.

What mileage does a BMW X6 usually have at its MOT?

The average odometer reading recorded at test is 80,932 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 BMW X6 get harder to pass as it ages?

Yes. At 3 to 5 years old, 87.3% of BMW X6 tests pass. By fifteen years or more, that falls to 75.0%. Nearly every model follows this pattern, which is why comparing raw pass rates between models is misleading unless age is accounted for.

Are most BMW X6 models petrol or diesel?

Of the BMW X6 cars tested, 83% are diesel, 10% are diesel hybrid, 6% are petrol. 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.
