This is a reasonable result that reflects typical UK reliability standards. Regular servicing and addressing advisories promptly will help keep your Sirion on the road.

The most common reasons a Daihatsu Sirion fails its MOT are vehicle structure corroded to the extent that the rigidity of the assembly is seriously reduced, the strength or continuity of the load bearing structure within 30cm of any sub-frame, spring or suspension component mounting (a 'prescribed area') is significantly reduced or inadequately repaired, the strength or continuity of the load bearing structure within 30cm of any seat belt anchorage (a 'prescribed area') is significantly reduced or inadequately repaired. If you are preparing your Sirion for its MOT, checking these areas first could save you a retest fee. Our detailed fault analysis includes estimated repair costs for each failure type.

Before buying a used Daihatsu Sirion, we recommend checking the full MOT history, write-off status, outstanding finance, and stolen vehicle status. These checks can be done for free using the registration number.
