2026 BYD Sealion 5 Comfort Phev Auto Hybrid electric (clean) · OS20 DLM

This BYD Sealion has no documented MOT history, rendering any assessment of roadworthiness or maintenance trends impossible. Without a single test record, there is no evidence to suggest whether the vehicle has been regularly serviced, neglected, or subjected to repeated failures. The absence of MOT data also means critical components—such as high-stress areas like the PHEV battery system, suspension subframes, or critical brake calipers—cannot be evaluated for wear or corrosion. Buyers must treat this as a vehicle with a completely unknown service and failure history, necessitating a thorough independent inspection before purchase. Mileage data is entirely absent, which complicates any evaluation of usage patterns. A 2026 model with no mileage figure implies either a brand-new vehicle (unlikely given the lack of MOTs) or a car that has never been driven or registered for testing. If the latter, the risk of undocumented structural deterioration—such as perished suspension bushes, degraded brake lines, or internal corrosion—is significantly elevated. Even if the vehicle has been lightly used, the absence of MOTs suggests either evasion of legal requirements or a deliberate omission from the record, both of which are red flags. Given the complete lack of MOT data, priority must be given to inspecting high-risk PHEV-specific components. The hybrid battery pack, cooling system, and high-voltage wiring loom require verification for leaks, swelling, or degraded insulation. Structural integrity of the underbody—particularly around wheel arches, subframes, and exhaust mounting points—must be scrutinised for corrosion, as this is often overlooked in low-mileage vehicles. Braking systems, including caliper binding and disc warping, should be tested dynamically, as PHEV vehicles often experience accelerated brake wear due to regenerative braking. Finally, the suspension (coil springs, bushes, and struts) should be checked for uneven wear or fluid leaks, as these are common failure points in vehicles with limited service history.
