What Is Daihatsu's MOT Pass Rate?
on 24 April 2026
Daihatsu vehicles have an overall pass rate of 72.3% based on 18,650 tests conducted between 2022 and 2024, according to DVSA anonymised MOT testing data. This figure is below the national average of 79.6%. The discrepancy indicates that Daihatsu vehicles are more likely to encounter issues during their MOT checks compared to other brands on UK roads.
Over the past three years, Daihatsu's MOT pass rate has shown a slight decline:
- In 2022: The pass rate was 73.3% based on 24,640 tests.
- In 2023: It fell to 72.8%, with 22,448 tests conducted.
- In 2024: The most recent data reveals a drop to 72.3% from 18,650 tests.
This trend suggests that Daihatsu vehicles are increasingly failing their MOT checks over time, though the rate of decline is modest.
Which Daihatsu Models Pass Their MOT Most Often?
Among Daihatsu models, several stand out in terms of test volume and pass rates:
- Sirion: With 72.7% of its tests passing, it's one of the more successful models. The Sirion underwent 7,088 MOT checks over this period with an average mileage of approximately 73,041 miles at the time of testing.
- Other Daihatsu models likely have varying pass rates, but specific figures aren't provided in the dataset.
The Sirion's performance is notable given its high test volume and average usage, indicating that it performs adequately under typical driving conditions. However, all owners should remain vigilant about potential issues as indicated by the overall trend of declining pass rates.

How to Save Money on Your Daihatsu MOT
Pre-MOT Checklist
Before taking your Daihatsu for its MOT, consider conducting a simple pre-test inspection:
- Lights: Check all external lights (headlights, taillights, indicators) are functioning correctly.
- Tyres: Ensure tyres have adequate tread depth and no visible damage or cuts.
- Wipers and Screen Wash: Confirm that wiper blades aren't excessively worn and the windscreen is clean.
Average MOT Cost
The DVSA sets a fixed fee of £54.85 for an MOT test, which remains consistent regardless of whether your Daihatsu passes or fails its inspection. However, additional costs may arise if repairs are needed to address advisories noted during the test.
Understanding that common advisories often turn into failures can help you prioritise necessary maintenance tasks and potentially avoid unexpected expenses. If your vehicle was financed via PCP (Personal Contract Purchase) or HP (Hire Purchase), it's worth checking whether there were any mis-selling issues affecting your finance agreement at mlj.org.uk.
By staying informed about common MOT failures for Daihatsu vehicles and addressing potential issues proactively, you can save both time and money while ensuring your vehicle meets the required safety standards.
