2017 Toyota Prius 1.8L Hybrid electric · OV66 HFF

The 2017 Toyota Prius’s latest MOT test on 2022-09-06 resulted in a failure marked as "Dangerous" due to the offside rear tyre having a tread depth below the legal minimum of 1.6mm, which is a critical roadworthiness issue. This is the only recorded MOT failure in its history, with the preceding test on the same date passing without defects, indicating a sudden and isolated problem rather than a developing maintenance trend. The vehicle’s MOT history is otherwise clean, suggesting that while this specific tyre failure was severe, the overall maintenance record up to this point has been stable and compliant with legal standards. The recorded mileage of 120,889 miles for a nine-year-old vehicle represents a high annual usage rate of approximately 13,432 miles per year, which is notably elevated for its age. Such mileage accumulation typically accelerates wear on consumables, including brake pads, suspension components, and drivetrain elements, as well as increasing the likelihood of tyre degradation, fluid degradation, and potential exhaust or emissions system stress. The absence of long periods of stationary use means that components such as the 12V battery, brake discs, and suspension bushes may have experienced more dynamic stress, potentially leading to premature fatigue or failure if not serviced regularly. Additionally, the high mileage could contribute to uneven tyre wear patterns, which may become evident during a test drive through lateral vibrations or excessive noise from the tyres. For the prospective buyer, the most urgent concern is the offside rear tyre failure, which must be addressed immediately to ensure road safety. Inspect the tyre for signs of internal damage, such as cord fraying or visible cuts, and verify that the remaining tread depth is sufficient for safe operation. During a test drive, listen for unusual tyre noise, particularly on cornering or acceleration, as this may indicate uneven wear or underlying structural issues. The buyer should also replace the tyre promptly to comply with legal requirements and prevent further degradation. Beyond this, given the vehicle’s high mileage, focus on the following checks: examine the brake system for signs of corrosion on discs or binding calipers, particularly if the car has been stationary for extended periods; inspect the suspension for clunking noises from worn bushes or damaged coil springs; and verify that all fluids, including brake fluid, coolant, and transmission fluid, are at the correct levels and free from contamination. Additionally, check for exhaust emissions leaks or unusual odours, as high mileage can accelerate these issues. In terms of age-appropriate maintenance, the buyer should also consider the following practical checks: inspect the tyre sidewalls for signs of perishing or cracking, which can weaken the tyre structure and lead to blowouts; verify the health of the 12V battery, as prolonged high mileage can strain it; and check for any visible corrosion on the chassis or undercarriage, particularly around wheel arches and exhaust components, which may indicate prolonged exposure to moisture or road salt. Given the vehicle’s age and usage profile, it is advisable to review the service history for compliance with Toyota’s recommended intervals, especially for fluid replacements and filter changes, as fluid degradation accelerates with time and mileage. Lastly, if the car has not been driven frequently, the buyer should ensure that the engine and drivetrain components are free from standing corrosion, as this can occur if the vehicle is left unused for extended periods.
