2009 Toyota Prius 1.5L Electric · RO09 YSA

The most recent MOT test on 2025-11-08 resulted in a passing outcome, though it followed a critical failure just two weeks prior, where the vehicle was deemed unroadworthy due to a dangerous front tyre bulge and excessive offside wheel bearing play. This pattern reveals a concerning trend of recurring severe mechanical issues, particularly in suspension and drivetrain components, with multiple major failures linked to structural integrity—such as the fractured rear coil spring and compromised constant velocity (CV) boots—indicating wear progression beyond the point of minor concern. The vehicle’s history also shows that while some advisories and minor defects were rectified, others, like the deteriorating ball joint dust cover and persistent tyre damage, suggest underlying wear that may have been overlooked during previous servicing. The combination of these failures underscores the need for immediate attention to prevent further deterioration, which could escalate into costly repairs or even safety risks. The 231,118 recorded miles for a 2009 Toyota Prius represents a high annual usage rate of approximately 13,595 miles per year, which is notably elevated for its age. Such mileage accumulation typically accelerates wear on consumables like brake pads, tyres, and suspension components, as well as drivetrain elements such as CV joints and wheel bearings. The rapid mileage suggests either frequent, heavy use or a lack of prolonged periods of inactivity, both of which can exacerbate mechanical stress. The absence of significant mileage gaps between MOT tests further implies consistent operation, which may have contributed to the observed deterioration in critical components like the coil springs and tyre structures. Buyers should be particularly cautious, as this usage profile often correlates with higher-than-average wear rates, necessitating a thorough inspection of all high-mileage areas. Given the vehicle’s history of major failures and recurring advisories, the prospective buyer should prioritise a comprehensive mechanical inspection to address the following critical areas. First, the fractured rear coil spring and compromised CV boots from the 2023 MOT failure indicate that the suspension and drivetrain are at advanced stages of wear. During a test drive, listen for unusual clunking noises from the suspension, especially when transitioning between rough and smooth road surfaces, which may signal further spring or bush failure. Additionally, check for uneven tyre wear patterns, as the tyre advisories suggest structural damage that could lead to blowouts if ignored. Inspect the front wheel bearings for excessive play, which the 2025 failure highlighted, by gently rotating the wheel while applying pressure to the brake pedal—any grinding or vibration could indicate imminent failure. The offside rear brake pads being dangerously thin below 1.5 mm also demand immediate attention, as this could compromise braking efficiency and safety; visually inspect the discs for scoring or corrosion and test the braking system for reduced responsiveness or pulsation during deceleration. For the buyer, the vehicle’s age and high mileage necessitate a proactive approach to maintenance beyond the MOT checks. Given the 17-year age, inspect the tyres for sidewall cracking or perishing, which can occur even with low mileage due to prolonged exposure to UV light and road salt. Check the 12V battery for signs of corrosion on terminals, weak electrical signals, or inability to start the engine, as standing vehicles can accelerate battery drain. Fluid levels should be verified, with particular attention to the brake fluid, which can degrade over time even without use; if the vehicle has been stationary for extended periods, flush the system to remove moisture. Service records should be cross-referenced with the MOT history to confirm adherence to manufacturer-recommended intervals for oil changes, timing belt replacement (if applicable), and suspension component servicing. If the vehicle has been in use, the wear on suspension bushes, ball joints, and CV joints may be more pronounced, so any creaking or rattling noises during movement should be investigated promptly. Finally, given the recurring lighting and lamp issues, ensure all electrical connections are secure and that the dipped beam headlamps are functioning correctly to meet legal standards.
