Moderate sample. 424 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 2020 Mazda CX-30 GT Sport Tech MHEV Auto is exceptionally reliable, with a first-time pass rate of 94.8%—well above the UK average of 80%—and only 4.5% of vehicles ever flagged for dangerous defects, which is reassuringly low. Petrol variants hold that same 94.7% pass rate, so fuel type isn't a differentiator here.

At a median mileage of 23,210 miles for a four-year-old car, these are genuinely low-mileage examples, which partly explains the strong results. The average vehicle has encountered just 0.23 failures and 2.4 advisories per test, suggesting minor wear items rather than systemic problems—when you're shopping for one, focus your pre-purchase inspection on brake condition and suspension components, as those typically dominate the advisory list.

The 2020 Mazda Cx 30 GT Sport Tech MHEV Auto passes its MOT first time more often than most UK vehicles (94.8% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.
