Should I check the MOT history before buying a 2017 Mazda Cx 5?

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 2017 Mazda Cx 5?

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.

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 2017 Mazda CX-5 is a genuinely reliable used buy, with an 89.2% first-time pass rate that sits well above the UK average of 80%—though the fact that 26.2% of these vehicles have recorded a dangerous defect at some point is a serious red flag worth investigating on any specific example. Petrol and diesel variants perform almost identically (90.0% and 88.9% respectively), so fuel choice shouldn't influence your reliability expectations here.

At 49,000 miles median, these are well-used family SUVs for their age, yet they're still averaging fewer than one failure per test and racking up 7.4 advisories—the latter pointing to wear items rather than structural problems. Before you buy, run a full service history check and have any vehicle with a previously flagged dangerous defect inspected by a Mazda specialist, because while the cohort is solid overall, that 26% dangerous mark means individual examples vary significantly.

The 2017 Mazda Cx 5 has a decent first-time pass rate (89.2%), 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 89.2% 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 7.4 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 7,263 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.
