2022 Hyundai Bayon Premium T-GDI Mhev 1.0L Hybrid electric (clean) · SM71 CFP

The defining mechanical story for this Bayon is short and largely uneventful, with only one MOT failure on file and that failure limited to a single component category. The most recent test on 26 January 2026 recorded a clean pass with no advisories and no defects, indicating that the wiper issue which caused the earlier failure on the same date was rectified before the car left the test station that day. The only other entry on the record, from 31 January 2025, was also a pass with no advisories, so across the two testable years the vehicle has demonstrated roadworthiness with no recurring advisories, no corrosion entries, and no structural or underbody concerns. The single advisory noted at the 2026 failure was a nail in the nearside rear tyre, which is a typical in-service puncture rather than a symptom of any underlying mechanical deterioration. With only 16,125 miles recorded over roughly four years, the Bayon has been used at an average rate of around 4,031 miles per year, which is low for its age bracket. Light annual mileage of this nature generally means slower wear on major drivetrain components such as the clutch, turbocharger and engine internals, but it can also bring its own considerations. Extended periods of low use can lead to moisture accumulation inside the engine sump, oxidation on brake discs causing surface corrosion, and deterioration of rubber components including tyres, wiper blades and suspension bushes that age with time rather than use. Given that the 2026 failure was specifically related to the front wiper blades failing to clear the windscreen effectively, rubber ageing is a relevant theme and worth bearing in mind when inspecting other weather-exposed rubber items. For a prospective buyer, the focus of any inspection should be on the rubber and elastomeric components that degrade with age rather than mileage. On a physical check, look closely at the front wiper blades for splitting, hardening or streaking, and consider replacing them proactively if there is any doubt about their condition. Inspect the tyres for sidewall cracking, tread depth and any signs of uneven wear, particularly on the nearside rear where the nail was recorded, as the repair patch should be checked for integrity and the wheel balanced correctly. Examine the brake discs for any surface rust that has become pitted or scored rather than a light film, as standing moisture can embed into the metal over time. Pay particular attention to the condition of the suspension bushes, anti-roll bar links and drop links, as low-mileage vehicles left standing can suffer from perished rubber in these areas without the driving cycles that would normally mask the symptom. On a test drive, listen for any clonking or knocking from the front suspension over uneven surfaces, particularly indicating worn bushes or droplinks. Test the steering for any wandering, vagueness or knocking through the rack, and feel for any vibration through the steering wheel under braking which could suggest disc run-out from corrosion or uneven pad transfer. Check the operation of the wiper system at both speeds and on intermittent setting to confirm full screen coverage, particularly on the passenger side where the offside blade was previously flagged. Finally, given the hybrid mild-hybrid architecture, confirm that the engine starts cleanly on the 12V system rather than the hybrid battery, listen for any irregular idle or misfire on cold start, and ensure the dashboard displays no warning lights for the emissions or regenerative braking systems, as these electrical faults would not necessarily appear on a standard MOT but could indicate developing concerns with the mild-hybrid drivetrain.
