Chrysler-Jeep Wrangler MOT pass rate & common failures

At a glance

Recorded pass rate

We are not publishing a ranking for the Wrangler. 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 700 tests and are worth reading on their own terms.

DVSA recorded wording

Most common failure items

Share of failed Chrysler-Jeep Wrangler tests in which each item was recorded. One failed test often lists several items, so these do not sum to 100%.

Common questions

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

We do not publish a comparison for the Chrysler-Jeep Wrangler, because the cars of this model that have been tested do not cover a wide enough range of ages and mileages.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 67.9% across 700 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 Chrysler-Jeep Wrangler?

The item recorded most often is "A lamp missing, inoperative or in the case of a multiple light source more than 1/2 not functioning", which appears in 16.4% of failed Chrysler-Jeep Wrangler 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 Chrysler-Jeep Wrangler?

The most common advisory is "A tyre seriously damaged", noted on 11.8% of all Chrysler-Jeep Wrangler 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 Wrangler usually have at its MOT?

The average odometer reading recorded at test is 93,089 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 Wrangler models petrol or diesel?

Of the Chrysler-Jeep Wrangler cars tested, 64% are petrol, 35% are diesel, 1% are lpg. Fuel type affects which items tend to fail, particularly emissions and exhaust components.

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.
