Is the Dacia Logan reliable?

On MOT evidence the Dacia Logan is about average. It passes 72.6% of tests once age and mileage are accounted for, against a national average of 72.3%. That figure covers 66% 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 Logan?

The item recorded most often is "Tyre tread depth not in accordance with the requirements", which appears in 13.7% of failed Dacia Logan 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 Logan?

The most common advisory is "Tyre tread depth not in accordance with the requirements", noted on 26.2% of all Dacia Logan tests. An advisory is not a failure: it flags something that will likely need attention before the next test.

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

The average odometer reading recorded at test is 79,375 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 Logan get harder to pass as it ages?

Yes. At 3 to 5 years old, 80.2% of Dacia Logan tests pass. By 12 to 14 years, that falls to 64.7%. 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 Logan models petrol or diesel?

Of the Dacia Logan cars tested, 50% are petrol, 50% 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.
