Isuzu TF MOT pass rate & common failures
From 1,338 recorded MOT tests of the Isuzu TF, published by DVSA.
Data updated
Quick answer
Across 1,338 MOT tests, 52.7% of Isuzu TF tests ended in a pass. This figure is not adjusted for age or mileage, so it is not a reliability ranking: the Isuzu TF 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 lamp missing, inoperative or in the case of a multiple light source more than 1/2 not functioning, which appears in 23.3% of failed tests. Cars of this model average 117,148 miles on the odometer when tested.
At a glance
Recorded pass rate
We are not publishing a ranking for the TF. 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 1,338 tests and are worth reading on their own terms.

Most common failure items
Share of failed Isuzu TF 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 Isuzu TF compared with other cars?
- We do not publish a comparison for the Isuzu TF, because the cars of this model that have been tested do not cover a wide enough range of ages and mileages.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 52.7% across 1,338 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 Isuzu TF?
- 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 23.3% of failed Isuzu TF 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 Isuzu TF?
- The most common advisory is "Brake pipe damaged or excessively corroded", noted on 36.6% of all Isuzu TF tests. An advisory is not a failure: it flags something that will likely need attention before the next test.
- What mileage does a Isuzu TF usually have at its MOT?
- The average odometer reading recorded at test is 117,148 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.
