Aston Martin DB11 MOT pass rate & common failures
From 2,611 recorded MOT tests of the Aston Martin DB11, published by DVSA.
Data updated
Quick answer
Across 2,611 MOT tests, 95.1% of Aston Martin DB11 tests ended in a pass. This figure is not adjusted for age or mileage, so it is not a reliability ranking: the Aston Martin DB11 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 windscreen washers not working or not providing sufficient fluid to clear the windscreen, which appears in 20.5% of failed tests. Cars of this model average 20,233 miles on the odometer when tested.
At a glance
Recorded pass rate
We are not publishing a ranking for the DB11. 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 2,611 tests and are worth reading on their own terms.

Common questions
- How reliable is the Aston Martin DB11 compared with other cars?
- We do not publish a comparison for the Aston Martin DB11, because the cars of this model that have been tested do not cover a wide enough range of ages and mileages.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 95.1% across 2,611 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 Aston Martin DB11?
- The item recorded most often is "Windscreen washers not working or not providing sufficient fluid to clear the windscreen", which appears in 20.5% of failed Aston Martin DB11 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 Aston Martin DB11?
- The most common advisory is "Tyre tread depth not in accordance with the requirements", noted on 14.9% of all Aston Martin DB11 tests. An advisory is not a failure: it flags something that will likely need attention before the next test.
- What mileage does a Aston Martin DB11 usually have at its MOT?
- The average odometer reading recorded at test is 20,233 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 Aston Martin DB11 get harder to pass as it ages?
- Yes. At 3 to 5 years old, 95.4% of Aston Martin DB11 tests pass. By 9 to 11 years, that falls to 95.6%. Nearly every model follows this pattern, which is why comparing raw pass rates between models is misleading unless age is accounted for.
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.
