Should I check the MOT history before buying a 2021 Hyundai Bayon SE Connect T Gdi MHEV A?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

This 2021 Hyundai Bayon is significantly more reliable than the UK average, with an 89.4% first-time pass rate compared to the national 80%, and only 6.8% of vehicles have ever recorded a dangerous defect—well below typical concern thresholds. The hybrid powertrain appears to be delivering on durability, with these cars averaging just 0.3 failures per test despite modest mileage of around 21,800 miles per vehicle.

At just three years old with relatively light use, these Bayons are in the early sweet spot of their lifecycle, which partly explains the strong pass performance. Focus your pre-purchase inspection on the advisory items (averaging 0.9 per vehicle) rather than major failures, and ask the seller for service history to confirm the hybrid system's been properly maintained, as this is where longevity gains are made.

We have limited data for the 2021 Hyundai Bayon SE Connect T Gdi MHEV A — treat the figures below as indicative rather than definitive.

⚠️ Around 1 in 20 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.
