Mercedes-Benz Eqv MOT pass rate & common failures
From 1,219 recorded MOT tests of the Mercedes-Benz Eqv, published by DVSA.
Data updated
Quick answer
Across 1,219 MOT tests, 87.8% of Mercedes-Benz Eqv tests ended in a pass. This figure is not adjusted for age or mileage, so it is not a reliability ranking: the Mercedes-Benz Eqv 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 39.1% of failed tests. Cars of this model average 50,316 miles on the odometer when tested.
At a glance
Recorded pass rate
We are not publishing a ranking for the Eqv. 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 1,219 tests and are worth reading on their own terms.
Electric car
How the Eqv compares with other electric cars
At 3 to 5 years old the Mercedes-Benz Eqv passes 87.3% of MOT tests, from 1,118 tests in that age band. Petrol and diesel cars of the same age pass 89.9%, so this model sits 2.6 points below that baseline. Among electric cars it ranks 24 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 Mercedes-Benz Eqv compared with other cars?
- We do not publish a comparison for the Mercedes-Benz Eqv, because the cars of this model that have been tested do not cover a wide enough range of ages and mileages.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 87.8% across 1,219 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 Mercedes-Benz Eqv?
- 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 39.1% of failed Mercedes-Benz Eqv 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 Mercedes-Benz Eqv?
- The most common advisory is "Tyre tread depth not in accordance with the requirements", noted on 16.0% of all Mercedes-Benz Eqv tests. An advisory is not a failure: it flags something that will likely need attention before the next test.
- What mileage does a Mercedes-Benz Eqv usually have at its MOT?
- The average odometer reading recorded at test is 50,316 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.
