Mazda Cx 5 GT Sport (2020)
2020 Mazda Cx 5 GT Sport
CarHunch analysed 107 real MOT records for the 2020 Mazda Cx 5 GT Sport. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2020 Mazda CX-5 GT Sport is significantly more reliable than the UK average, with a 93.5% first-time pass rate compared to 80% nationally, and only 5.6% of vehicles ever developing a dangerous defect—well below the threshold for real concern. These cars are barely run in at nearly 4 years old, with a median of just 27,755 miles, so you're looking at unusually light use for the age.
When failures do occur, they're minor: the average vehicle racks up only 0.27 failures but 2.3 advisories, suggesting wear items and niggles rather than structural problems. If you're buying one, get a pre-purchase inspection to flag those advisory items early, but the core mechanicals have proven solid in this cohort.
What to check before buying a 2020 Mazda Cx 5 GT Sport
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.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
