The picture
Across 843 MOT tests, the Cx-5 Sport returns 89.7% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is brake pads worn below 1.5 mm. A seriously damaged tyre and a defective wiper blade round out the top three. Average tested mileage sits at 24,211, which is the lens to read those failure rankings through. If you own one and the next test is close, the ranked list below is a sensible pre-test checklist.

Year-band analysis
First-time MOT pass rate split by registration band. A 1.5-point gap between bands is modest — the year you buy Mazda CX 5 Sport makes a small but real difference to MOT outcomes.
Best band to buy
90.0%
2021+ registration
the 2021-on band climbs to 90.0% — a 1.5-point improvement. Failures here are mostly wear items: has a cut in excess of the…, less than 1.5 mm thick — the structural issues that drag down older examples don't appear in the top-10 for this band. Post-2020 examples are early in their MOT life and generally show the cleanest records.
Band to be cautious about
88.5%
2018–2020 registration
On the 2018–2020 band, the data shows a 88.5% pass rate against a fleet average of 90.0% on the newer band. The main culprits logged at test: blade defective, damaged but not adversely affecting driver's view, and does not clear the windscreen effectively. Average mileage on test for this band is 30,159 miles — high-mileage wear items are a recurring theme.
Best band to buy: 2021+ (90.0% first-time pass). Worst band to avoid: 2018-2020 (88.5% pass). That's a 1.5-point spread across 1,218 older tests and 3,102 newer ones — year of build makes a material difference on this model.
