The 2017 Mazda 3 passes its MOT first time at 85.7%, comfortably above the UK average of 80%, which is a solid sign of reliability. However, 30.5% of vehicles have recorded a dangerous defect at some point, which is notably high and worth taking seriously during any pre-purchase inspection. Petrol versions perform slightly better than diesel at 86.1% versus 83.4% pass rate, so fuel type does make a marginal difference here.

At a median mileage of 37,088 miles for a 2017, these cars are running low for their age, which partly explains the good pass rate—don't expect the same results from higher-mileage examples. The average of 1.18 failures and 8.6 advisories per vehicle suggests minor wear rather than systemic problems, but before buying, get a full history check to confirm no dangerous defects are lurking in the MOT record.

The 2017 Mazda 3 has a decent first-time pass rate (85.7%), 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 85.7% 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 8.6 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 8,258 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.
