2006 Toyota Prius 1.5L Electric · RO56 XUP

A recurring mechanical theme runs through the DVSA record of this 2006 Toyota Prius: the engine management system has been flagged for a malfunction indicator lamp (MIL) issue on two separate occasions, and the offside front outer drive shaft constant velocity (CV) boot has split twice, most recently at the 2026-01-19 test where it was the reason for failure alongside an offside rear position lamp defect and a minor registration plate lamp fault. That same vehicle passed a re-test three days later on 2026-01-22 once the lamp issue and CV boot were presumably rectified, with only a tyre edge-wear advisory remaining. Across seven recorded tests there are three failures and a string of advisories spanning front brake disc pitting, hazed headlamp lenses, deteriorating number plate, worn rear brake pads and a fuel smell inspection. The pattern is one of an older hybrid being kept broadly on the road but with repeated emissions/electrical and driveline sealing defects that recur rather than fully resolve. Mileage accumulation at 228,153 miles over a 20-year life works out to an average of roughly 11,400 miles per year, which is consistent with regular mixed-use driving. The recorded tests are spread fairly evenly from 2021 through to 2026, with no multi-year gaps that would suggest a long stationary period; the 2023 test in particular is notable for recording zero advisories, suggesting a brief window when components were in good order. However, the combination of average-to-high annual mileage for a vehicle of this age and the recurring CV boot and MIL faults points to typical wear items being addressed piecemeal at test time rather than through major scheduled overhaul. For a prospective buyer, the offside front CV joint is the single component demanding the closest physical inspection. Because the boot has split twice, the joint itself should be checked for any clicking or knocking under sharp load, particularly when turning full lock at low speed or when accelerating from a standstill in a tight circle. Listen for a rhythmic clunk on initial acceleration and feel for vibration through the steering. The engine MIL has illuminated twice; any dashboard warning light during a test drive should prompt immediate diagnostic interrogation, as Prius-specific hybrid system faults can range from catalytic converter efficiency issues to inverter or EVAP system problems that an MOT test alone will not fully diagnose. The 2024 advisories on pitted front brake discs and the 2026 advisory on an offside front tyre worn on edge suggest uneven braking behaviour is plausible, so a test drive should include firm pedal application to check for judder through the pedal or steering, and the car should be tracked at a steady speed on a straight road to verify there is no pulling to one side. On the test drive, also pay attention to the rear brakes, which were flagged as wearing thin in 2021, and to the overall feel of the brake pedal for any sponginess that could indicate caliper binding or hydraulic issues at this mileage. The advisory regarding a strong fuel smell in 2021 means any workshop inspection should include a careful look under the car and around the fuel filler neck, particularly around the hybrid system fuel lines and vapour recovery system, for fresh staining or weeping. Given the age and the pattern of minor recurring electrical and sealing defects, a pre-purchase inspection at a garage familiar with Toyota hybrids would be a sensible precaution, with particular attention paid to the 12V auxiliary battery condition, inverter coolant level, and the condition of the underbody bracing and exhaust heat shields where corrosion tends to begin on high-mileage examples of this generation.
