The Daihatsu Sirion has an overall MOT pass rate of 77.3% across 250,499 real MOT tests — comfortably above the UK average, which puts it among the more reliable models on UK roads.
The most common problems on the Daihatsu Sirion are tyre tread depth below requirements of 1.6mm (5,610 recorded failures), windscreen wiper does not clear the windscreen effectively (4,083), and brake pipe excessively corroded (2,684). These are the faults most likely to cause an MOT failure on this model, so check for them carefully on any test drive or pre-purchase inspection. Many are wear-and-tear items that can be budgeted for, but a car that's already failing on multiple fronts may signal neglected maintenance.
On the safety side, the most frequently flagged dangerous fault is tyre tread depth below requirements of 1.6mm. Dangerous faults cause an immediate MOT failure and mean the vehicle is not roadworthy until repaired. If you're viewing a Daihatsu Sirion with an expired or recently passed MOT, ask the seller whether any dangerous faults were found and fixed during the last test.
A typical Daihatsu Sirion owner drives around 3,921 miles per year. If the car you're looking at is significantly above this, expect more wear on suspension, brakes and tyres. If it's well below, the vehicle may have been sitting unused — check for perished rubber, corroded discs and stale fluids.
In terms of longevity, most Daihatsu Sirion models stay on UK roads for around 28 years — a strong showing that suggests solid build quality and readily available parts. If you're buying one that's already approaching that window, the data suggests it has plenty of life left provided it's been maintained.
Before committing to a purchase, we recommend running a full vehicle history check on the specific car. This will reveal any outstanding finance, stolen markers, write-off history and mileage discrepancies that the seller may not disclose — and that the MOT data alone can't tell you.
