The 2015 Mazda CX-3 passes its MOT on the first attempt 86.9% of the time, comfortably ahead of the UK average of 80%, which is a solid result. However, nearly 29% of these vehicles have recorded a dangerous defect at some point, which is significantly higher than typical and worth investigating in any used example you're considering—check the full MOT history carefully.

At a median mileage of 41,363 miles for a nine-year-old car, these are relatively well-used but not excessively worn examples. The average vehicle accumulates 1.33 failures and 8.3 advisories per test, suggesting minor issues crop up regularly; focus your pre-purchase inspection on brake wear, suspension components, and lighting, which typically dominate the advisory list for this age and mileage.

The 2015 Mazda Cx 3 has a decent first-time pass rate (86.9%), 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

✅ Good baseline reliability. A 86.9% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.

🔧 Expect consumable spend. An average of 8.3 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 2,405 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.
