Moderate sample. 474 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

This 2021 Hyundai Bayon is significantly more reliable than the UK average, with a first-time MOT pass rate of 91% against the national benchmark of 80%, and only 3.6% of vehicles ever flagged for dangerous defects—a reassuringly low figure. The hybrid powertrain appears to be proving durable in the field.

At just over 24,500 miles median, these are genuinely low-mileage examples, which explains the strong pass rate and minimal failure rate of 0.25 per vehicle. Before buying, check the service history carefully, as hybrids need proper maintenance to keep brakes and batteries in good condition, even when mileage looks light.

The 2021 Hyundai Bayon SE Connect T Gdi MHEV passes its MOT first time more often than most UK vehicles (91.8% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.
