2026 BYD Sealion 5 Comfort Phev Auto Hybrid electric (clean) · LS26 KOB

The most recent MOT test record for the 2026 BYD SEALION 5 COMFORT PHEV AUTO shows that no MOT has yet been performed, which is typical for a vehicle of this age that is still within its initial road‑tax exemption period. Consequently there is no historical data on pass/fail outcomes or advisory notes from which to infer a maintenance trend; the expectation for a brand‑new, factory‑sealed PHEV is that the mechanical condition will be sound provided the original build quality has been maintained and the vehicle has not been subjected to abnormal abuse. Mileage information is not supplied, so a direct comparison with the vehicle’s 2026 model year cannot be made. In the absence of recorded kilometres, a prudent buyer should assume a typical first‑year usage of between 5,000 and 10,000 miles, which places average wear on tyre tread, brake components and the high‑voltage traction battery within normal parameters. If the seller can provide a logbook or telematics read‑out showing a substantially higher figure, the buyer should be alert to accelerated wear of the brake discs, suspension bushings and tyre sidewalls, as well as the possibility of early degradation of the lithium‑ion battery pack due to deep‑cycle cycling. Given the lack of MOT data and the vehicle’s recent introduction, the buyer’s inspection should concentrate on age‑related, time‑based checks. Examine the tyre tread depth and sidewall condition; even if tread is adequate, sidewalls can become brittle after a few years of storage, especially if the car has been kept stationary for extended periods. Verify that the 12‑volt auxiliary battery shows a healthy voltage and that the high‑voltage traction battery is within the manufacturer’s state‑of‑charge window, looking for any dashboard warnings or error codes that might indicate cell imbalance or cooling system issues. Inspect the brake discs and pads for surface rust or uneven wear, and confirm that the calipers move freely without binding; a short, low‑speed test should reveal any pulsation or shudder that would suggest uneven disc thickness. Check all fluid reservoirs—engine oil, coolant, brake fluid and windshield washer—ensuring they are at the correct levels, clear of contaminants and have not exceeded the recommended service intervals, as many fluids degrade with time even when the car is not driven heavily. Finally, confirm that the vehicle’s service history, even if brief, includes the initial 12‑month or 10,000‑mile service as stipulated by BYD, and that any software updates for the electric drivetrain, infotainment system and emissions controls have been applied. Look for signs of corrosion on the under‑body, particularly around the battery pack mounting points and suspension joints, which can develop if the car has been stored in a damp environment. A thorough visual inspection of the high‑voltage cable routing, connector integrity and coolant‑to‑inverter heat exchangers will help ensure that the PHEV’s hybrid systems remain sealed and functional. Should any of these checks reveal irregularities, negotiate remedial work or a warranty extension before finalising the purchase.
