2015 Toyota Prius 1.8L Hybrid electric (clean) · FN15 FKO

The Toyota Prius has passed its most recent MOT on 2026-01-23 at 159,238 miles, but the record reveals a concerning trend of repeated minor failures and advisories that suggest inconsistent maintenance. The vehicle’s roadworthiness is currently stable in terms of passing the test, though the pattern of recurring issues—particularly with brake discs, tyres, and exhaust leaks—indicates a lack of proactive care. The most recent advisories for worn brake discs (both front and rear) and tyres running close to legal limits are not critical failures but signal impending wear that, if unaddressed, could escalate into binding calipers or uneven braking. The repeated tyre-related advisories, spanning multiple tests from 2022 to 2026, imply basic upkeep was neglected, potentially leading to premature tread failure or structural damage to wheel rims. The mileage accumulation of 159,238 miles over 11 years—averaging approximately 14,476 miles annually—is unusually high for a vehicle of this age, suggesting either intensive use or prolonged periods of inactivity with deferred maintenance. The gaps between tests are consistent at one year, but the rapid mileage gain between 2022 (116,037 miles) and 2024 (145,588 miles) raises questions about whether the vehicle was driven aggressively or stored poorly, accelerating wear on suspension bushes, drivetrain components, and corrosion-prone areas. The failure in 2022 for a missing wheel fixing at 116,037 miles further underscores potential neglect, as such issues can worsen over time if not promptly addressed. A buyer should prioritise an independent inspection of the brake system, particularly the rear calipers and discs, given their repeated advisories and the risk of binding or uneven wear. The front and rear tyres, which have consistently been flagged for tread depth or damage, should be examined for uneven wear patterns, perishing, or embedded debris that could indicate alignment or suspension issues. The minor exhaust leak, noted in both 2023 and 2024, warrants verification of its persistence, as persistent leaks can affect emissions and engine efficiency. Finally, the suspension components—including coil springs, bushes, and struts—should be scrutinised for corrosion or excessive play, especially given the vehicle’s age and mileage, as these are common failure points in high-mileage hybrids. Rust around wheel arches, sills, and the subframe should also be assessed, as prolonged exposure to moisture accelerates structural degradation.
