2023 Hyundai Bayon Premium T-GDI Mhev 1.0L Hybrid electric (clean) · FN23 SWU

With only a single DVSA MOT pass on record from July 2025 and no advisories or defects listed, this Bayon's documented roadworthiness history is essentially a clean slate. The vehicle secured a first-time pass at its initial test, meaning it presented no defects significant enough to warrant even advisory attention under DVSA criteria. For a car of this age and specification, that blank canvas is broadly reassuring but should be read alongside the fact that it is still early in its testing life — only one full MOT cycle has elapsed, so the long-term wear patterns on consumables and chassis components have yet to be formally recorded. The recorded mileage of 25,461 against a three-year age equates to an annual accumulation of roughly 8,500 miles, which sits comfortably within typical usage for a small MHEV crossover of this class. There are no gaps in testing history to suggest extended periods off the road, nor any rapid mileage escalation between records that might indicate commercial or high-intensity use. This steady, moderate rate of accumulation should mean the engine, transmission, hybrid ancillary systems, and braking components have experienced normal rather than accelerated wear, and that the 1.0-litre turbocharged petrol unit — known to be sensitive to infrequent oil changes and short-trip use — has likely seen sufficient running to keep the combustion and exhaust systems in good order. From a buyer's standpoint, the absence of recorded advisories means there is no specific flagged component to target during inspection, but it is worth focusing attention on the areas commonly affected in T-GDi MHEV units and chassis components of this age. On a test drive, listen for any faint rattle or diesel-like knock from the engine on cold start, which can point to timing chain stretch on these small turbo units, and monitor for any hesitation or judder under light throttle that could indicate carbon build-up from urban driving cycles. Check that the 48-volt mild hybrid system operates smoothly, with the integrated starter-generator delivering the expected seamless restarts without warning lights on the dashboard. Pay particular attention to the rear suspension on poorer road surfaces, as torsion beam setups on the Bayon can develop knocking or creaking from the trailing arm bushes as mileage progresses, and verify that the steering remains centred with no pulling to either flank. Finally, inspect the underside and around the wheel arches for any early signs of surface corrosion, even though this age and mileage would not normally raise structural concerns. Confirm the brake pedal feel is firm with no sponginess, and on a moderate-speed stop check for any vibration through the steering wheel that would indicate disc warp — common on cars used heavily in urban stop-start traffic. Ensure all tyre sidewalls show even wear across both axles, as uneven wear can reveal tracking or suspension geometry issues not yet severe enough to be flagged at MOT. A clean record such as this lowers but does not eliminate the need for a thorough physical inspection, particularly given that the DVSA pass only certifies the vehicle met minimum standards on the day of test.
