2006 Toyota Prius Electric · WD51 ADD

The most recent MOT test in February 2026 resulted in a pass, but the vehicle's overall maintenance trend is concerning. The history shows a pattern of recurring failures and significant advisories that suggest the vehicle is experiencing accelerating age-related deterioration. While the most recent test cleared the major structural and suspension faults found in January 2026, the remaining advisories regarding the rear sub-frame and brake pipes indicate that the underlying issues of corrosion and component wear have not been fully resolved, but rather are being monitored as they progress toward future failure points. With 211,794 miles recorded, the vehicle has averaged roughly 10,600 miles per year over its twenty-year lifespan. This is standard usage for a vehicle of this type, indicating it has not been sitting idle for long periods, which is generally positive for hybrid battery health. However, this consistent usage means that mechanical components such as suspension bushes, wheel bearings, and braking systems have undergone significant cumulative stress. The high mileage, combined with the documented history of structural corrosion, suggests the vehicle is in a high-maintenance phase of its lifecycle where component fatigue is a primary concern. During a test drive, you must pay close attention to the chassis and suspension. The history of major failures regarding the offside rear suspension mounting and the rear sub-frame necessitates a thorough inspection of the vehicle's underside for heavy corrosion or structural thinning. Listen for any heavy clunking, knocking, or rhythmic thumping from the rear or front suspension, which would indicate failing bushes or worn mounting points. The advisory concerning the offside rear brake pipe being covered in grease is particularly noteworthy, as grease is frequently used to conceal active corrosion; you should ensure the pipe is structurally sound and not merely masked. The braking system also requires scrutiny. Given the advisories for pitted and scored front discs and thinning pads, check for any brake shudder through the pedal or a pulling sensation when applying the brakes. You should also inspect the front shock absorbers for any signs of fresh oil misting, which would indicate a loss of damping integrity. Finally, because of the high mileage and the age of the vehicle, confirm that the hybrid battery system has been serviced and check for any signs of fluid leaks from the engine or transmission, as the cumulative wear on seals and gaskets is likely to be significant.
