Mazda Cx 5 (2017)
2017 Mazda Cx 5
CarHunch analysed 7,263 real MOT records for the 2017 Mazda Cx 5. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
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.
What to check before buying a 2017 Mazda Cx 5
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- ⚠️ 26.2% of these vehicles have had a dangerous defect recorded. Enter the reg below — the full MOT history will show exactly what was flagged and whether it was resolved.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
