Should I check the MOT history before buying a 2014 Mazda 3?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

What corrosion should I look for when inspecting a 2014 Mazda 3?

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

How are tyres and brakes typically on a 2014 Mazda 3?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

The 2014 Mazda 3 passes its MOT first time at 83.7%, comfortably above the UK average of 80%, which suggests solid baseline reliability—though the concerning figure is that 42.8% of vehicles have recorded a dangerous defect at some point, a notably high proportion that warrants a pre-purchase inspection. Petrol versions perform slightly better than diesels (84.2% vs 82.0% pass rate), so if you have a choice, petrol is the safer bet.

These cars are running at around 55,844 miles on average, which is reasonable for a 2014, but the 1.88 average failures per vehicle and 13.0 advisories per vehicle suggest wear is accumulating—brake, suspension, and lighting issues are cropping up regularly. Before committing to a purchase, have a trusted mechanic do a full pre-MOT check, and specifically ask them to inspect the braking system and suspension components, as these are the typical weak points at this age and mileage.

The 2014 Mazda 3 has a decent first-time pass rate (83.7%), 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

🔧 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 13 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 8,873 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.

Tyre wear 47.3%

Offside Front Tyre worn close to legal limit/worn on edge · Nearside Front Tyre worn close to legal limit/worn on edge · Offside Rear Tyre slightly damaged/cracking or perishing · …

Based on vehicles from this manufacture year that had at least one MOT test in each calendar year. Data from 2017–2025.
