What Is the Daihatsu Sirion MOT Pass Rate?
on 24 April 2026
The Daihatsu Sirion, a popular subcompact car known for its affordability and efficiency, has an MOT pass rate of 72.7%, based on DVSA anonymised data from 2024. Out of 7,088 total tests conducted, the vehicle passed in just under three-quarters of cases, with a fail rate of 27.3%. This figure is notably lower than the national average MOT pass rate of 79.6%, indicating that the Daihatsu Sirion faces some specific challenges when undergoing annual inspections.
Common Daihatsu Sirion MOT Failures
Owners of the Daihatsu Sirion should be aware of several common issues that often lead to MOT failures, enabling them to take proactive measures before their next test date. One frequent area of concern is lighting and electrical systems, which account for a significant portion of failures. Issues such as faulty brake lights, malfunctioning indicators, or worn-out headlight bulbs can easily cause the vehicle to fail its MOT.
Another common issue affecting the Daihatsu Sirion is suspension problems. Worn shock absorbers, damaged springs, or misaligned wheels can compromise road safety and lead to a test failure. Regular maintenance checks on these components are important for maintaining safe driving conditions and ensuring a successful MOT outcome.
exhaust system issues also frequently result in failed MOT tests for the Daihatsu Sirion. Cracked or leaking pipes, worn-out gaskets, and clogged catalytic converters can all contribute to poor emissions performance, which is rigorously checked during an MOT test. Ensuring that your Sirion's exhaust is free from corrosion and securely fastened could save you a lot of time and money in the long run.

Before undergoing an MOT, it's wise for Daihatsu Sirion owners to perform some basic checks themselves. Checking brake pads, tyre tread depth, and fluid levels can help identify potential issues early on. reviewing the condition of lights, windscreen wipers, and battery terminals is important for passing this vital safety check.
Daihatsu Sirion Mileage and Reliability
The average mileage at which a Daihatsu Sirion undergoes its MOT test stands at 73,041 miles, according to DVSA data from 2024. This figure provides valuable insights into typical ownership patterns of the vehicle. The relatively high average suggests that many owners keep their Sirions for an extended period before either selling them or trading up to a newer model.
However, this mileage also highlights potential reliability concerns. As cars age and accumulate more miles, they typically require more frequent maintenance and repairs. For Daihatsu Sirion owners who are approaching this milestone in terms of mileage, it's important to be vigilant about regular servicing and component replacements to maintain vehicle safety and performance.
the MOT pass rate discrepancy between the national average and that of the Daihatsu Sirion could indicate a need for more thorough maintenance practices among its drivers. Regularly scheduled services at authorised garages can help identify potential issues early on, thereby increasing the chances of passing an MOT test without significant repairs being required at the last minute.
This can provide additional support to owners facing unexpected costs due to MOT failures, especially if these are related to manufacturing defects.
To sum up, while the Daihatsu Sirion has a lower MOT pass rate compared to the national average, understanding common failure points and conducting regular pre-MOT checks can significantly improve its chances of passing. By staying informed about maintenance needs specific to this model and keeping up with recommended service schedules, owners can enjoy safer driving conditions and smoother transitions through annual vehicle inspections.
