2026 BYD Sealion 5 Design Phev Auto 1.5L Hybrid electric (clean) · LL26 OUU

There is no recorded MOT history available for this 2026 BYD Sealion 5 Design PHEV automatic. As the vehicle is currently of an age that would not yet require statutory MOT testing under current DVSA regulations, the absence of any test record is entirely expected and does not itself indicate any mechanical concern. With no pass certificates, failure notices, or advisories on file, it is not possible to draw any conclusions regarding a maintenance trajectory, as there are simply no data points from which to identify whether the vehicle has been maintained in a stable, improving, or deteriorating condition. Any assessment must rely on physical inspection and service documentation rather than historical test outcomes. The recorded mileage for this vehicle is noted as unknown, which precludes any meaningful assessment of annual usage rates, mileage gaps, or patterns of accumulation. Given that the Sealion 5 is a relatively new model in the BYD range and this particular example is a 2026 registration, it is reasonable to anticipate low to moderate mileage consistent with a nearly new vehicle, possibly in the region of a few thousand to perhaps ten or fifteen thousand miles depending on whether it has been used as a daily driver, a commuter vehicle, or primarily for shorter journeys. PHEV powertrains in particular often accumulate lower annual mileages when owners rely on the electric-only mode for shorter trips. That said, low or irregular usage carries its own mechanical considerations, particularly regarding the 12V auxiliary battery health, potential brake disc corrosion from prolonged standing, and the high-voltage battery management system, all of which benefit from regular use and periodic charging cycles. Because there is no MOT history to draw upon, the prospective buyer should focus on establishing a comprehensive service and provenance record. Confirm that the vehicle has been serviced in accordance with BYD manufacturer schedules, with documented evidence in the service book or digital service history, particularly regarding the PHEV-specific items such as the high-voltage battery condition report, charging system diagnostics, inverter coolant replacement, and any software updates that may have been issued. Verify the presence of all essential documentation, including the owner's manual, charging cable set, and any remaining manufacturer warranty cover, as the BYD factory warranty and PHEV component warranty are material factors for a buyer. Inspect the charging port and cable for damage or wear, and where possible confirm the state of charge and any error messages via the infotainment or BYD app interface. From a physical inspection standpoint, given the vehicle's near-new status and probable low mileage, attention should be directed towards age-related and standing-related deterioration rather than wear from extensive use. Examine the tyres closely for sidewall perishing, cracking, or ultraviolet degradation, particularly if the vehicle has been stored outdoors, as tyres can deteriorate from age alone regardless of tread depth. Check the brake discs for signs of surface corrosion or binding calipers, which can develop on lightly used vehicles and manifest as uneven braking, pulling to one side, or a grinding sensation on the first application of the brakes after standing. Inspect the bodywork and undertray for any transit damage, stone chip accumulation, or evidence of accident repair, and verify that all PHEV-specific warning lights extinguish correctly upon ignition and that the hybrid system transitions smoothly between electric and petrol modes during a test drive. During the road test, listen for any unusual noises from the suspension, confirm smooth regenerative braking function, and ensure the charging system operates correctly on a suitable home or public charger prior to purchase.
