Is the Peugeot 308 reliable?

On MOT evidence the Peugeot 308 is below average. It passes 67.5% of tests once age and mileage are accounted for, against a national average of 72.3%, which ranks it 202 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 Peugeot 308?

The item recorded most often is "A spring or spring component fractured or seriously weakened", which appears in 17.6% of failed Peugeot 308 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 Peugeot 308?

The most common advisory is "Tyre tread depth not in accordance with the requirements", noted on 30.7% of all Peugeot 308 tests. An advisory is not a failure: it flags something that will likely need attention before the next test.

What mileage does a Peugeot 308 usually have at its MOT?

The average odometer reading recorded at test is 83,507 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 Peugeot 308 get harder to pass as it ages?

Yes. At 3 to 5 years old, 85.8% of Peugeot 308 tests pass. By fifteen years or more, that falls to 50.8%. Nearly every model follows this pattern, which is why comparing raw pass rates between models is misleading unless age is accounted for.

Are most Peugeot 308 models petrol or diesel?

Of the Peugeot 308 cars tested, 65% are diesel, 34% are petrol, 1% are hybrid. 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.
