2023 Hyundai Bayon Premium T-GDI Mhev 1.0L Hybrid electric (clean) · KB03 FUN

The most recent DVSA MOT test on 17 August 2026 returned a Pass with no defects recorded, indicating that at the point of examination the vehicle met the minimum roadworthiness standard. However, it is important to note that an earlier test on the same date recorded a Fail on two Prescribed (dangerous) defects relating to both nearside and offside headlamp aim being too high, referenced under section 4.1.2 (a) of the MOT inspection manual. Because no separate retest advisory or follow-up advisory was recorded in the data provided, the immediate rectification appears to have been carried out before the Pass certificate was issued the same day. With only this single failure point and no other advisory history to compare against, the overall maintenance trend can be regarded as broadly stable, though this single episode warrants targeted physical confirmation by the buyer. The recorded mileage of 24,364 miles on a three-year-old vehicle equates to an average of just over 8,100 miles annually, which sits broadly within the typical usage range for a modern supermini-class crossover of this age. This level of use implies that the wear-prone components such as brake pads, discs, tyres, clutch and suspension bushes should have experienced normal rather than accelerated degradation. However, the mileage accumulation pattern is not fully visible from the MOT data alone, and lower-running examples can still suffer from time-related deterioration. Given the relatively modest annual mileage, combined with the lack of any recorded advisories, it is reasonable to infer that the consumable items have not yet been subjected to excessive wear, but this should be verified through service history documentation rather than assumed. Given that the defect history is limited to a single headlamp aim issue, attention should be focused on confirming the rectification was performed properly and remains compliant, particularly after a load or passengers have been carried. During a test drive, the buyer should observe the beam pattern on a flat surface such as a garage door or wall at night, ensuring the cut-off line is below headlamp centre height and does not dazzle oncoming traffic. If the vehicle has been laden with heavy items or has had suspension or rear-loading modifications, the beam may once again drift upward. It is also prudent to check the headlamp level adjuster mechanism, where fitted, to confirm it operates smoothly through its range and is not seized, as binding adjusters are a common cause of MOT failure on this defect. Beyond the recorded MOT outcome, a three-year-old Hyundai Bayon with relatively modest mileage warrants several age-appropriate physical inspections regardless of its clean test history. Tyres should be examined closely for sidewall perishing or cracking, which can occur from UV exposure and age even when tread depth remains legal, and the production date code on the sidewall should be checked to confirm the tyres are not original fitment drying out. The 12V auxiliary battery, which supports the mild-hybrid system functions, should be tested for state of health, especially if the vehicle has stood for extended periods, as MHEV systems can be sensitive to voltage drop. Brake discs should be inspected for corrosion lips and the calipers for any signs of binding from infrequent use, while a check of fluid degradation dates is advisable, including brake fluid, which typically requires replacement every two years regardless of mileage, and coolant, which may be approaching its first scheduled renewal. Finally, verifying the service book stamps or digital service record is essential to confirm that the manufacturer-recommended MHEV system checks, oil changes, and filter replacements have been carried out at the correct intervals, as missing services can affect both mechanical longevity and any remaining warranty cover.
