The 2021 Hyundai Bayon Premium T-GDI MHEV Auto is significantly more reliable than the UK average, with a 95.9% first-time MOT pass rate versus the national 80%, and only 1.5% of vehicles have ever recorded a dangerous defect. This hybrid petrol is a genuinely dependable proposition for buyers concerned about unexpected failure costs.

At just under 20,000 miles median for a three-year-old car, these examples are lightly used, which partly explains the strong pass rate—but the low failure count of 0.12 per vehicle suggests the engineering itself is sound. Before buying, get a full service history check and have any vehicle with over 25,000 miles inspected by a Hyundai specialist, as mileage variation at this age can indicate usage patterns worth understanding.
