2005 Toyota Prius 1.5L Electric · AF05 TEO

The most recent MOT test for this 2005 Toyota Prius occurred on 2022-10-08, where the vehicle passed with no recorded defects, following a previous failure in the same month due solely to misaligned windscreen washer jets. This suggests a brief period of maintenance or adjustment, but the intervening clean MOT records from 2021 and 2020 indicate a generally stable maintenance trend up to that point. However, the earlier failures—particularly the 2020 test, which highlighted major issues with electrical systems (nearside position lamp, dipped beam headlamp, and wiper ineffectiveness) alongside ABS and ESC faults—raise concerns about underlying electrical or electronic module degradation. The advisory from 2018, noting corroded coil springs and underbody rust, underscores the vehicle’s susceptibility to structural and suspension wear, which may have been exacerbated by prolonged exposure to harsh conditions or lack of preventative maintenance. The lack of explicit mileage data makes it impossible to accurately assess annual usage rates or whether the Prius has accumulated excessive wear, but the MOT history suggests periods of both low and potentially high activity. The 2020 failure coincides with a potential period of rapid mileage accumulation, given the electrical and wiper-related issues, which could indicate heavy use or environmental stress. Conversely, the absence of wear-related advisories in the more recent MOTs may imply either controlled usage or effective corrective action. However, the 2018 advisories—particularly the thin rear brake pads and near-side front tyre wear—highlight a need for closer inspection of braking systems and tyre condition, as these could deteriorate further with continued use. Without mileage context, the buyer should assume the vehicle may have undergone varying levels of stress, with potential for accelerated wear in certain components. Given the mixed MOT history, the buyer should prioritise a thorough pre-purchase inspection focusing on the electrical systems, as the 2020 failures suggest persistent issues with wiring, fuses, or control modules. On test drive, listen for unusual electrical noises, check for consistent operation of all lamps (including dipped beam and indicator functions), and verify that the ABS and ESC systems engage properly without warning light persistence. The corroded coil springs and underbody rust from 2018 warrant immediate attention to structural integrity, particularly around the suspension and chassis, as corrosion can compromise alignment and handling. Inspect the suspension for excessive play, uneven tyre wear patterns, or clunking noises when driving over bumps, which may indicate worn bushes or damaged springs. Additionally, the thin rear brake pads from 2018 require replacement, and the buyer should confirm that the brake system has been serviced since then, as standing corrosion or binding calipers can lead to reduced braking efficiency or uneven wear. For the Prius’s age and the recorded advisories, the buyer should also conduct a detailed physical inspection of the vehicle’s exterior and undercarriage. Check for signs of tyre sidewall perishing, which is common in older vehicles due to ozone exposure and prolonged storage, even if mileage is low. Inspect the tyres for uneven wear or cracks in the tread, as the 2017 advisories suggest some wear has already occurred. Verify the condition of the 12V battery, as electrical faults can exacerbate corrosion in connectors and wiring, and test the brake system for corrosion on discs or binding calipers, which may have developed from prolonged idling or lack of use. Fluid levels should be checked—particularly brake fluid, coolant, and transmission fluid—with a focus on calendar-based servicing, as fluids degrade over time regardless of mileage. Finally, review any service records or receipts for the suspension, electrical systems, and corrosion protection treatments, as these would provide further insight into the vehicle’s maintenance history and the extent of any deferred repairs.
