What is the Daihatsu MOT pass rate?

60.9% of 11,871 class-4 initial MOT tests on Daihatsu cars passed first time in 2024 — below the 71.2% UK average across all published models.

Which Daihatsu has the best MOT pass rate?

Of the Daihatsu model groups with a substantial sample, the Sirion has the highest initial pass rate at 60.4% across 5,869 tests. Pass rates track vehicle age closely, so newer model groups tend to sit higher.

Does a good Daihatsu pass rate mean the car I am looking at is fine?

No. A model-level rate describes a population, not one vehicle. Enter the registration for that car's own MOT, tax and mileage record, and check for outstanding finance, write-off and stolen markers before you buy.

What Daihatsu cars fail on

The items most often behind a first-test failure across Daihatsu model groups, as a share of Daihatsu tests. DVSA publishes each model group's six most common categories, so this ranks the biggest published causes rather than every possible one.

Suspension Arms — 8.8% of Daihatsu tests. Worn arms or bushes. A common age-related repair that affects handling and tyre wear.
Exhaust Emissions — 5.9% of Daihatsu tests. The car exceeded its emissions limits. Can be a sensor or a service, but on a diesel it can also mean an expensive filter or catalyst.
Brake Performance — 5.1% of Daihatsu tests. The brakes underperformed on the rolling road. Expect brake work rather than an adjustment.
Component Mounting Prescribed Areas — 4.3% of Daihatsu tests. Corrosion near a mounting point for a tested component. This is the kind of rust that gets expensive — inspect it.
Headlamp Aim — 3% of Daihatsu tests. Headlights pointing too high or low. Cheap to adjust, and common on every make.
Headlamps — 2.6% of Daihatsu tests. A headlight fault, from a blown bulb to a failed unit.
Anti-roll Bars — 2.6% of Daihatsu tests. Worn anti-roll bar links or bushes. Inexpensive but often recurring.
Position Lamps — 1.3% of Daihatsu tests. A side or tail light out. Usually a bulb.

Methodology and limitations

MOT outcomes describe testable items at the time of inspection. They are not a measure of overall mechanical reliability.

Scope: Class 4 normal initial MOT tests completed in 2024. Models require at least 1,000 qualifying tests. Duplicate source rows are removed using official DVSA test IDs.
