Moderate sample. 473 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.
The 2020 Mazda CX-30 Sport Lux MHEV Auto is a reliable performer, with a first-time MOT pass rate of 95.5%—well above the UK average of 80%—and only 4.2% of vehicles ever developing a dangerous defect, which is low enough not to raise concerns. The petrol engine variant (which accounts for essentially all examples here) maintains this strong pass rate consistently.
These cars are running at sensible mileage for their age, averaging just over 25,000 miles, and when failures do occur they're rare at 0.19 per vehicle. The typical advisory count of 2.4 per test suggests minor maintenance items rather than systemic problems, so budget for routine upkeep but expect few surprises—when shopping, prioritise a full service history over the MOT result alone, since this model rarely fails on its own.
The 2020 Mazda Cx 30 Sport Lux MHEV Auto passes its MOT first time more often than most UK vehicles (95.7% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.
