2006 Toyota Prius 1.5L Hybrid electric (clean) · YY56 HRD

The vehicle's roadworthiness is currently compromised by a significant and worsening trend of structural degradation. While the most recent test on 13 November 2025 at 85,124 miles resulted in a pass, this followed a severe failure just four days earlier. The November 2025 failure revealed critical issues including seriously weakened outer sills, excessively corroded suspension component mountings, and a sub-frame that was both front and rear seriously weakened by corrosion. Although the vehicle passed after repairs, the transition from minor corrosion advisories in previous years to major structural failures indicates that the chassis integrity is rapidly deteriorating. The mileage pattern shows a very low annual average of approximately 4,256 miles, which is consistent with a vehicle of this age. Between November 2024 and November 2025, the car covered 6,298 miles, showing a slight increase in usage compared to the historical average. While low mileage often suggests less mechanical wear on the drivetrain, the records indicate that the vehicle has likely spent considerable time in environments conducive to corrosion, as evidenced by the persistent issues with brake pipes, sub-frames, and suspension mountings dating back to at least 2015. A prospective buyer must prioritise a thorough underside inspection to assess the extent of the structural repairs carried out following the November 2025 failure. The history of recurring corrosion on suspension mounting areas and the sub-frame suggests that the vehicle's structural integrity is the primary risk. Specific attention should be paid to the sills and the rear axle, both of which have been flagged for corrosion across multiple test cycles. The tester also noted a corroded offside rear brake hose ferrule in the most recent pass, which implies that even after major structural work, minor corrosion remains present in the braking system. Beyond the chassis, the recurring issues with brake discs, pitted surfaces, and corroded brake pipes suggest that maintenance has often been reactive rather than preventative. The history of failing on CV boots and seat belt webbing indicates that basic consumable upkeep has been inconsistent. Given the recent severity of the structural failures, a specialist inspection of the welding and replacement components is essential to ensure the vehicle is truly safe for continued road use.
