2004 Toyota Prius 1.5L Petrol · GR04 KHH

A pattern of progressive wear and corrosion emerges from the MOT record, with recurring advisories for suspension arm bush wear, rear brake pipe corrosion and brake disc surface deterioration, plus a persistent oil mist on the off‑side front shock absorber and intermittent engine MIL faults. The most recent 2024 test still recorded the front tyre edge wear and shock‑absorber oil mist, while the vehicle passed overall, indicating that the underlying issues have not yet escalated to a failure but remain unresolved. At 208,070 mi the car averages roughly 9,500 mi per annum, a mileage rate that sits comfortably within normal usage for a 22‑year‑old model. Annual testing shows no significant gaps, suggesting the odometer reading is consistent with the recorded service intervals. This level of mileage will have accelerated the natural wear of consumables such as tyres, suspension bushings, brake discs and hydraulic lines, which aligns with the advisories noted across multiple years. When inspecting the suspension, pay particular attention to the near‑side and off‑side rear arm pins and bushes for any looseness, knocking sounds over bumps or a vague steering wander that could indicate the wear flagged in 2021 and 2022. Examine the rear brake pipe for signs of corrosion, rust streaks or fluid seepage, and test the brake pedal for a soft or spongy feel that might betray a compromised line. The front and rear brake discs were noted as pitted but not severely weakened; during a drive, feel for any pulsation or vibration through the pedal or steering wheel under braking, which would suggest the discs are approaching the end of their serviceable life. The front shock absorber’s oil mist advisory warrants a visual check for any oil residue on the shock body or surrounding suspension components, and a road test should reveal any loss of damping through excessive bounce or reduced ride comfort. The off‑side front tyre edge wear should be measured for tread depth and uniformity, while the engine MIL fault recorded in both 2021 and 2024 calls for a diagnostic scan to confirm whether the fault is intermittent or indicative of a deeper electronic or emission issue. Finally, inspect the rear chassis rails and body panels for any rust progression beyond the “not excessive” description, as hidden corrosion can affect structural integrity over time. A thorough pre‑purchase inspection covering these points will give a realistic appraisal of the remedial work required before committing to purchase.
