2016 Toyota Prius 1.8L Hybrid electric · OU66 RNA

The most recent MOT test on 9 August 2023 resulted in a pass with no defects or advisories recorded. Evaluating the broader history, the vehicle has maintained a very stable and clean record over the last several years. While there were failures in 2019 and 2020, these were limited to consumables such as wiper blades and brake pads, alongside a dust cover on the anti-roll bar linkage. Since 2021, the vehicle has passed its inspections without any noted issues, suggesting a consistent maintenance regime and a stable overall mechanical condition. The vehicle has covered 140,965 miles over approximately ten years, averaging roughly 14,096 miles per annum. This is considered high usage for a private vehicle, though it is typical for Prius models often employed for urban commuting or fleet duties. Such high mileage implies significant cumulative wear on long-term consumables and drivetrain components. While the Toyota hybrid system is renowned for its longevity, this level of usage increases the likelihood of degradation in the suspension geometry, engine mounts, and the overall capacity of the hybrid battery system compared to a lower-mileage example. Given the absence of recent advisories, the buyer should focus on age-and-mileage-appropriate wear that may not yet trigger an MOT failure but affects long-term reliability. During a test drive, listen for clunks or knocks from the suspension, specifically around the anti-roll bar linkages and suspension bushes, as these are high-wear items on high-mileage vehicles. Check for uneven tyre wear across the axles, which could indicate a need for wheel alignment. Inspect the brake discs for significant lipping or surface corrosion and ensure there is no shuddering under braking, which would suggest warped discs or binding calipers. Furthermore, verify the service history for evidence of regular oil changes and hybrid system health checks. Inspect the 12V auxiliary battery for signs of age or terminal corrosion, as these can cause erratic electrical behavior in hybrid vehicles. Examine all rubber seals and tyre sidewalls for perishing or cracking caused by age. Finally, ensure the coolant levels and quality are correct for both the internal combustion engine and the hybrid inverter, as these are critical for the thermal management of the drivetrain and are often overlooked in high-mileage examples.
