Is the Volkswagen Jetta reliable?

On MOT evidence the Volkswagen Jetta is below average. It passes 69.3% of tests once age and mileage are accounted for, against a national average of 72.3%. That figure covers 76% 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 Volkswagen Jetta?

The item recorded most often is "A spring or spring component fractured or seriously weakened", which appears in 22.9% of failed Volkswagen Jetta 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 Volkswagen Jetta?

The most common advisory is "Tyre tread depth not in accordance with the requirements", noted on 28.7% of all Volkswagen Jetta tests. An advisory is not a failure: it flags something that will likely need attention before the next test.

What mileage does a Volkswagen Jetta usually have at its MOT?

The average odometer reading recorded at test is 113,596 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 Volkswagen Jetta get harder to pass as it ages?

Yes. At 6 to 8 years old, 77.1% of Volkswagen Jetta tests pass. By fifteen years or more, that falls to 61.3%. Nearly every model follows this pattern, which is why comparing raw pass rates between models is misleading unless age is accounted for.

Are most Volkswagen Jetta models petrol or diesel?

Of the Volkswagen Jetta cars tested, 82% are diesel, 18% are petrol. Fuel type affects which items tend to fail, particularly emissions and exhaust components.

Volkswagen Jetta MOT pass rate & common failures

From 11,393 recorded MOT tests of the Volkswagen Jetta, published by DVSA.

Data updated 29 July 2026

Quick answer

The Volkswagen Jetta passes 69.3% 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 below average. Based on 11,393 tests. Its most commonly recorded failure is spring or spring component fractured or seriously weakened, which appears in 22.9% of failed tests. Cars of this model average 113,596 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.
