The 2006 Daihatsu Sirion sits almost exactly at the UK average with a 79.6% first-time pass rate, but the headline concern is that nearly a third (32.5%) of these cars have recorded a dangerous defect at some point—well above typical levels and a genuine red flag for prospective buyers. This suggests underlying reliability issues that go beyond routine wear.

At 50,000 miles median mileage for an 18-year-old car, these Sirions have been relatively well-used but not excessively so, yet they're still accumulating an average of 3.56 failures and 22.6 advisories per test, indicating persistent mechanical problems across the fleet. Before viewing one, get a pre-purchase inspection that specifically flags the brake system, steering, and suspension components—the areas where dangerous defects cluster—and factor in above-average maintenance costs.

The 2006 Daihatsu Sirion has a decent first-time pass rate (79.6%), but a higher-than-average share of vehicles have had serious defects recorded — the individual vehicle's history matters a lot here.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context
🔧 Average reliability. Passes at roughly the UK rate — not a standout, not a problem vehicle. Individual history makes all the difference.
🔧 Expect consumable spend. An average of 22.6 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.
🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 1,601 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.

Watch for defects — worth knowing

What tends to go wrong

Across 1,601 vehicles — figures show how many had each issue flagged at least once in their MOT history.

Brake wear 62.8%
Front Brake pad(s) wearing thin · Front brake disc worn, pitted or scored, but not seriously weakened · Offside Rear Brake pipe corroded, covered in grease or other material · …
Ask the seller when brakes were last serviced. If they don't know, factor in the cost.
Tyre wear 48%
Nearside Front Tyre worn close to the legal limit · Offside Front Tyre worn close to the legal limit · Nearside Front Tyre worn close to legal limit/worn on edge · …
Budget for a full set — on a vehicle this age, tyres are expected consumables. An inspection will confirm how much is left.
Suspension & steering 35%
Nearside Front Anti-roll bar linkage has slight play in a ball joint · Offside Front Anti-roll bar linkage has slight play in a ball joint · Offside Front Anti-roll bar linkage ball joint has slight play
Harder to spot without a ramp — this is a good reason to book a pre-purchase inspection.
Other issues 22.4%
Oil leak, but not excessive
