2006 Toyota Prius 1.5L Hybrid electric · LM06 SEO

A recurring pattern of minor fluid and exhaust leaks defines the mechanical history of this vehicle, suggesting a gradual decline in sealing integrity consistent with its age. While the car passed its latest inspection on 28 July 2025, the reappearance of advisories for an exhaust leak and a front oil leak—both of which were previously flagged in 2022—indicates these are persistent issues. The most recent test also introduced a new concern regarding severely deteriorated dust covers on the front lower anti-roll bar ball joints, signaling that the rubber components of the chassis are now reaching a critical stage of wear. The recorded mileage of 143,177 miles over approximately 20 years reflects a steady usage rate of roughly 7,159 miles per year. This consistent accumulation suggests the vehicle has avoided long periods of stagnation, which typically benefits the hybrid battery and engine seals. However, the total mileage puts the vehicle in a bracket where wear on suspension linkages, engine mounts, and exhaust manifolds is expected, and the current MOT advisories are a direct reflection of this cumulative mechanical fatigue. Prospective buyers should focus on the persistent oil leak at the front of the engine and the exhaust leak during a physical inspection. Check the underside of the engine bay for fresh oil residue and listen for a huffing or whistling sound from the exhaust system, particularly under load. While the oil leak has been described as not excessive, its recurrence over several years warrants a closer look to ensure it is not impacting other engine bay components or contributing to fluid loss. The deterioration of the front lower anti-roll bar ball joint dust covers requires specific attention during the test drive. Listen for knocking or clunking noises when driving over speed bumps or during low-speed maneuvers, as compromised dust covers allow road grit to enter the joint, leading to accelerated wear. Ensure the steering feels precise and free from unusual play or vibrations, as the failure of these joints will eventually necessitate a full replacement of the linkage to maintain structural roadworthiness.
