2026 BYD Seal U Boost DM-I Phev Auto 1.5L Hybrid electric (clean) · LL75 FXK

This BYD SEAL, tested on January 7, 2026, at just 176 miles, achieved a clean pass with no defects recorded. The absence of advisories or failings in its single MOT history suggests the vehicle has undergone no mechanical or structural concerns during its brief operational life. The most recent test confirms the car remains roadworthy under current DVSA standards, though the data remains too limited to establish long-term reliability trends. The recorded mileage of 176 miles, combined with the vehicle’s 2026 registration, indicates it has seen minimal use. There are no gaps in testing—only a single pass within its first six months—but the low mileage precludes meaningful wear analysis. A buyer should note that such low mileage may reflect either careful owner usage or limited real-world testing before sale. Given the lack of MOT history beyond the initial pass, an in-person inspection should prioritise the high-voltage battery system, given the PHEV configuration, and verify electrical connections for corrosion or wear. The suspension components, including coil springs and bushes, should be examined for premature degradation, though the low mileage reduces this risk. Brake discs and pads, while unlikely to show significant wear at this stage, warrant a visual check for uneven wear patterns or binding calipers. Structural integrity, particularly around the battery housing and underbody, should be scrutinised for any signs of corrosion or improper installation.
