2015 Toyota Prius 1.8L Hybrid electric (clean) · DX15 FDK

The most recent MOT inspection on 8 July 2026 resulted in a pass, though it introduced a new advisory regarding light oil misting on the nearside front shock absorber. When reviewing the broader maintenance trend, the vehicle shows signs of progressive wear in the suspension and safety components rather than a stable or improving pattern. While the vehicle has successfully passed recent tests, the history reveals a recurring cycle of advisories and failures related to consumables and wear items, such as suspension bushes, tyres, and lighting. The transition from worn suspension bushes in 2025 to oil misting on a shock absorber in 2026 suggests that the front suspension system is entering a phase of more significant component degradation that will require monitoring. With 170,461 miles recorded over approximately eleven years, this Toyota Prius has averaged roughly 15,500 miles per year. This represents a high-usage profile, which is consistent with a hybrid vehicle often used for long-distance commuting or taxi work. High annual mileage typically accelerates the mechanical fatigue of chassis components, rubber bushings, and damping units. While high mileage can sometimes indicate a well-maintained vehicle that has been regularly driven rather than left to sit, it also means the vehicle is approaching a stage where major wear-and-tear items, such as the hybrid battery cooling system, suspension geometry, and braking hardware, are more likely to require replacement due to cumulative stress. During a test drive, you should pay close attention to the front end of the vehicle for any signs of instability or noise. The advisory for oil misting on the nearside front shock absorber indicates a potential seal failure; listen for any knocking or clunking sounds when driving over uneven surfaces or speed bumps, as this could signal that the damper is losing its ability to control spring oscillation. Furthermore, the history of worn suspension arm bushes and anti-roll bar bushes suggests that the steering may feel vague or imprecise. You should check for any wandering at motorway speeds or sudden changes in direction, which could indicate that the previously advised bush wear has progressed into a more significant mechanical fault. Regarding the tyres and safety equipment, the previous advisories for perishing rubber and worn edges suggest that the vehicle's maintenance has occasionally lapsed regarding tyre management. Inspect the sidewalls of all tyres for any signs of cracking or perishing, particularly on the nearside rear, and check the tread depth across the entire width of the tyre to ensure even wear. You should also verify that all exterior lighting, including the registration plate lamp and main beam headlamps, is fully operational, as the history shows these have failed in the past. Given the high mileage, it is also advisable to confirm that the service history includes regular oil changes and that the hybrid system's cooling filters have been cleaned, as these are critical for the long-term health of a high-mileage Prius.
