2008 Toyota Prius 1.5L Petrol · FH08 OJR

The 2008 Toyota Prius presents a stable and sound mechanical history, culminating in a clean pass at 169,517 miles during the most recent test on 18 November 2025. The maintenance trend remains consistently positive, with no recorded defects across all successful MOT tests. The vehicle failed its initial attempt on the exact same day at 169,516 miles, yet the record shows zero defects for both the failure and the subsequent pass. This anomaly repeats from the September 2024 test at 161,676 miles, indicating the failures likely stemmed from minor emissions anomalies or sensor readouts rather than structural or mechanical deterioration. The absence of advisories or defects suggests the hybrid drivetrain, braking system, and suspension components have remained within acceptable tolerances. The mileage accumulation aligns closely with typical usage for an eighteen-year-old vehicle, averaging roughly 9,400 miles annually. Between the August 2022 test at 149,079 miles and the September 2024 test at 161,676 miles, the Prius covered 12,597 miles over a two-year gap, reflecting a slightly lower annual rate of around 6,300 miles. Usage increased marginally over the following twelve months, adding 7,841 miles before the November 2025 test. The data lacks any sudden spikes or prolonged periods of inactivity, pointing to consistent, steady ownership rather than extended standing or severe short-term wear. Despite the pristine MOT record, a physical inspection must focus on the typical failure points of aging hybrid vehicles and the general wear expected at nearly 170,000 miles. Examine the inverter coolant pump and the hybrid battery cooling intake for blockages, as restricted airflow degrades the nickel-metal hydride battery pack. Check the brake calipers for signs of binding, a common issue on hybrids where regenerative braking reduces mechanical usage and causes corrosion on sliding pins. Inspect the rear suspension bushes and coil springs for deterioration, alongside the exhaust system for corrosion, which often escapes detection during a brief MOT if surface rust has not yet penetrated the metal. Verify the condition of the 12-volt auxiliary battery and the starter motor, as these components endure frequent cycling in hybrid applications. A thorough road test should confirm the seamless transition between electric and petrol power, ensuring the internal combustion engine starts smoothly without excessive vibration or hesitation.
