Is the Tesla Model S reliable?

On MOT evidence the Tesla Model S is well above average. It passes 81.5% of tests once age and mileage are accounted for, against a national average of 72.3%. That figure covers 62% of the national age and mileage range, which is enough to quote but not to rank. 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 Tesla Model S?

The item recorded most often is "Tyre tread depth not in accordance with the requirements", which appears in 24.2% of failed Tesla Model S 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 Tesla Model S?

The most common advisory is "Tyre tread depth not in accordance with the requirements", noted on 30.5% of all Tesla Model S tests. An advisory is not a failure: it flags something that will likely need attention before the next test.

What mileage does a Tesla Model S usually have at its MOT?

The average odometer reading recorded at test is 89,392 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 Tesla Model S get harder to pass as it ages?

Yes. At 3 to 5 years old, 81.1% of Tesla Model S tests pass. By 9 to 11 years, that falls to 76.6%. Nearly every model follows this pattern, which is why comparing raw pass rates between models is misleading unless age is accounted for.

Tesla Model S MOT pass rate & common failures

From 10,836 recorded MOT tests of the Tesla Model S, published by DVSA.

Data updated 29 July 2026

Quick answer

The Tesla Model S passes 81.5% of MOT tests once results are adjusted for the age and mileage of the cars tested, against a national average of 72.3%. That is well above average. Based on 10,836 tests. Its most commonly recorded failure is tyre tread depth not in accordance with the requirements, which appears in 24.2% of failed tests. Cars of this model average 89,392 miles on the odometer when tested.

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.
