2009 Toyota Prius 1.8L Hybrid electric (clean) · LS59 WDO

The most recent MOT test, conducted on 22 October 2025, resulted in a Pass, although it should be noted that a failure was also recorded on the same date prior to rectification, indicating that repairs were carried out to achieve the pass outcome. Reviewing the broader MOT history, the maintenance trend appears stable rather than progressively worsening, as the vehicle has consistently passed its annual tests over the past several years. However, a recurring pattern of advisories and occasional failures points to areas of chronic wear that any prospective buyer should monitor closely. The 2024 test saw significant Major defects including a leaking front shock absorber, an illuminated supplementary restraint system warning lamp, an inoperative engine management indicator lamp, and non-functioning front position lamps, all of which were subsequently remedied to achieve a pass. With a recorded mileage of 236,875 miles over approximately 17 years, this Toyota Prius has averaged around 13,934 miles per year, which represents moderately high usage for its age and indicates that the vehicle has been used as a regular, active driver rather than being left standing for prolonged periods. This consistent annual mileage suggests that primary wear components such as the engine, transmission, suspension, and braking system have experienced steady use rather than suffering the particular degradation that often affects low-mileage or stored vehicles. That said, the high cumulative mileage places additional importance on verifying the condition of the hybrid system battery pack, inverter coolant pump, and the 1.8-litre Atkinson cycle petrol engine, all of which are subject to fatigue over such extended service. There is no evidence of any mileage gap suggesting the vehicle was laid up, which is generally favourable for mechanical continuity but does mean consumables have been worked hard. Several recurring advisories warrant close inspection prior to purchase. The persistent oil leak noted across multiple tests, although not deemed excessive, should be physically examined to determine whether it originates from the engine sump, valve cover gasket, or rear main seal, as continued leakage can lead to oil fouling on the exhaust system and potential engine wear if neglected. The rear brake discs and brake pipes have been repeatedly flagged for corrosion, pitting, and scoring, which on a test drive may manifest as brake shudder under heavy pedal application, particularly from higher speeds, and an extended braking distance in wet conditions; the discs will likely require replacement at the next service interval. The nearside rear coil spring corrosion advisory has appeared across consecutive years, suggesting progressive structural degradation that could eventually lead to spring failure, with symptoms including a clonking noise over uneven surfaces and visible vehicle sag at the rear. The steering rack free play and shock absorber fluid leak are both indicative of wear that compromises handling precision and safety, and a thorough road test should focus on detecting any wandering at motorway speeds, uneven tyre wear suggesting alignment or suspension issues, and any warning lamps remaining illuminated on the instrument cluster, as the supplementary restraint system fault recorded in 2024 could recur if the underlying issue was not comprehensively repaired. Beyond the documented advisories, given the vehicle's age and accumulated mileage, a prospective buyer should conduct several additional physical checks. The 12V auxiliary battery, which is critical to the operation of the hybrid system boot-up sequence, should be load-tested as these typically require replacement every four to six years and a failing unit can prevent the vehicle from entering ready mode. All four tyres should be inspected closely for sidewall cracking and perishing, which is common on vehicles of this age regardless of tread depth, and the wheels examined for corrosion around the rim bead that may prevent effective sealing. Brake fluid, engine coolant, and inverter coolant should be checked for service history, as these fluids degrade with calendar age and require periodic replacement to prevent internal corrosion within the hybrid cooling system and brake hydraulic components. The hybrid battery pack should ideally be diagnosed using a Toyota Techstream or compatible OBD tool to confirm cell balance and state of health, as this is the single most expensive potential failure point on a Prius of this generation. Finally, verifying a complete service book history with documented oil and filter changes at appropriate intervals will provide confidence that the high-mileage engine and drivetrain have been maintained to a standard consistent with longevity.
