DS DS4 MOT pass rate & common failures

From 4,945 recorded MOT tests of the DS DS4, published by DVSA.

Data updated

Quick answer

Across 4,945 MOT tests, 67.1% of DS DS4 tests ended in a pass. This figure is not adjusted for age or mileage, so it is not a reliability ranking: the DS DS4 fleet does not yet cover a wide enough spread of ages and distances to compare it fairly against other models. Its most commonly recorded failure is transmission shaft constant velocity joint boot missing or no longer prevents the ingress of dirt etc, which appears in 31.6% of failed tests. Cars of this model average 62,665 miles on the odometer when tested.

We are not publishing a ranking for the DS4. The examples tested do not cover a wide enough spread of ages and mileages to compare it fairly, and an unadjusted pass rate mostly sorts models by how recently they were bought rather than how well they were built. The failure and advisory patterns below come from the same 4,945 tests and are worth reading on their own terms.

Share of all DS DS4 tests carrying each advisory. The denominator differs from the failure list above because an advisory can be issued on a car that passed.

Common questions

How reliable is the DS DS4 compared with other cars?
We do not publish a comparison for the DS DS4, because the cars of this model that have been tested do not cover a wide enough range of ages and mileages. Its raw pass rate is 67.1% across 4,945 tests, but comparing a raw rate between models mostly ranks them by how new they are rather than how good they are. The failure and advisory patterns further down the page are still drawn from real tests and are worth reading.
What is the most common MOT failure on a DS DS4?
The item recorded most often is "A transmission shaft constant velocity joint boot missing or no longer prevents the ingress of dirt etc", which appears in 31.6% of failed DS DS4 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 DS DS4?
The most common advisory is "Tyre tread depth not in accordance with the requirements", noted on 31.0% of all DS DS4 tests. An advisory is not a failure: it flags something that will likely need attention before the next test.
What mileage does a DS DS4 usually have at its MOT?
The average odometer reading recorded at test is 62,665 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 DS DS4 get harder to pass as it ages?
Yes. At 3 to 5 years old, 89.7% of DS DS4 tests pass. By 9 to 11 years, that falls to 62.4%. Nearly every model follows this pattern, which is why comparing raw pass rates between models is misleading unless age is accounted for.
Are most DS DS4 models petrol or diesel?
Of the DS DS4 cars tested, 70% are diesel, 26% are petrol, 3% 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. No adjusted rate is shown because this model's tested examples do not cover enough of the national age and mileage range for standardisation to mean anything.

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.
