How reliable is the Chrysler-Jeep Grand Voyager compared with other cars?

We do not publish a comparison for the Chrysler-Jeep Grand Voyager, because the cars of this model that have been tested do not cover a wide enough range of ages and mileages.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 55.5% across 921 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 do testers most often warn about on a Chrysler-Jeep Grand Voyager?

The most common advisory is "Tyre tread depth not in accordance with the requirements", noted on 29.2% of all Chrysler-Jeep Grand Voyager tests. An advisory is not a failure: it flags something that will likely need attention before the next test.

What mileage does a Chrysler-Jeep Grand Voyager usually have at its MOT?

The average odometer reading recorded at test is 120,111 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.

Are most Chrysler-Jeep Grand Voyager models petrol or diesel?

Of the Chrysler-Jeep Grand Voyager cars tested, 87% are diesel, 13% are petrol. Fuel type affects which items tend to fail, particularly emissions and exhaust components.

Chrysler-Jeep Grand Voyager MOT pass rate & common failures

From 921 recorded MOT tests of the Chrysler-Jeep Grand Voyager, published by DVSA.

Data updated 29 July 2026

Quick answer

Across 921 MOT tests, 55.5% of Chrysler-Jeep Grand Voyager tests ended in a pass. This figure is not adjusted for age or mileage, so it is not a reliability ranking: the Chrysler-Jeep Grand Voyager 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 strength or continuity of the load bearing structure within 30cm of any sub-frame, spring or suspension component mounting (a 'prescribed area') is significantly reduced or inadequately repaired, which appears in 20.9% of failed tests. Cars of this model average 120,111 miles on the odometer when tested.

We are not publishing a ranking for the Grand Voyager. 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 921 tests and are worth reading on their own terms.

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.
