Ford Mustang Mach-E MOT pass rate & common failures

From 6,939 recorded MOT tests of the Ford Mustang Mach-E, published by DVSA.

Data updated

Quick answer

Across 6,939 MOT tests, 89.6% of Ford Mustang Mach-E tests ended in a pass. This figure is not adjusted for age or mileage, so it is not a reliability ranking: the Ford Mustang Mach-E 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 tyre tread depth not in accordance with the requirements, which appears in 45.0% of failed tests. Cars of this model average 35,381 miles on the odometer when tested.

We are not publishing a ranking for the Mustang Mach-E. 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 6,939 tests and are worth reading on their own terms.

Electric car

How the Mustang Mach-E compares with other electric cars

At 3 to 5 years old the Ford Mustang Mach-E passes 89.7% of MOT tests, from 6,838 tests in that age band. Petrol and diesel cars of the same age pass 89.9%, so this model sits 0.2 points below that baseline. Among electric cars it ranks 13 of 43.

There is no emissions test for an electric car and the MOT does not check the battery. Electric cars as a group fail slightly more often than same-age petrol cars, almost entirely on tyres and suspension, because they are heavier and deliver full torque instantly.

Common questions

How reliable is the Ford Mustang Mach-E compared with other cars?
We do not publish a comparison for the Ford Mustang Mach-E, because the cars of this model that have been tested do not cover a wide enough range of ages and mileages.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 89.6% across 6,939 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 Ford Mustang Mach-E?
The item recorded most often is "Tyre tread depth not in accordance with the requirements", which appears in 45.0% of failed Ford Mustang Mach-E 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 Ford Mustang Mach-E?
The most common advisory is "Tyre tread depth not in accordance with the requirements", noted on 34.1% of all Ford Mustang Mach-E tests. An advisory is not a failure: it flags something that will likely need attention before the next test.
What mileage does a Ford Mustang Mach-E usually have at its MOT?
The average odometer reading recorded at test is 35,381 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.

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.
