Dacia Duster MOT pass rate & common failures

At a glance

Pass rate, adjusted for age and mileage

The Duster is 5.6 percentage points below the national pass rate once age and mileage are accounted for, which is below average. The unadjusted figure is 71.1%; the difference is what the age and mileage of this model’s fleet was hiding.

Warnings without a failure

Common questions

Is the Dacia Duster reliable?

On MOT evidence the Dacia Duster is below average. It passes 66.7% of tests once age and mileage are accounted for, against a national average of 72.3%. That figure covers 78% 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 Dacia Duster?

The item recorded most often is "Wiper blade missing or obviously not clearing the windscreen", which appears in 15.0% of failed Dacia Duster 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 Dacia Duster?

The most common advisory is "Tyre tread depth not in accordance with the requirements", noted on 22.7% of all Dacia Duster tests. An advisory is not a failure: it flags something that will likely need attention before the next test.

What mileage does a Dacia Duster usually have at its MOT?

The average odometer reading recorded at test is 52,990 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 Dacia Duster get harder to pass as it ages?

Yes. At 3 to 5 years old, 80.6% of Dacia Duster tests pass. By 12 to 14 years, that falls to 56.5%. Nearly every model follows this pattern, which is why comparing raw pass rates between models is misleading unless age is accounted for.

Are most Dacia Duster models petrol or diesel?

Of the Dacia Duster cars tested, 55% are petrol, 41% are diesel, 4% are petrol and gas bi-fuel. 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.
