2007 Toyota Prius 1.5L Hybrid electric · SM07 RNO

The 2007 Toyota Prius presents a mechanical profile marked by recurring suspension and braking system failures that have persisted across multiple MOT assessments, culminating in a successful test on 2026-01-15 following several prior failures. The vehicle has suffered two outright MOT failures—one in December 2023 involving parking brake inefficiency and binding rear service brakes, and another in January 2025 covering similar suspension wear and lighting faults—before passing the most recent examination in early 2026. While the latest result is positive, the pattern of persistent component failures rather than isolated issues suggests underlying structural weaknesses that may not have been fully resolved even after the intervening passes. The car's overall roadworthiness remains compromised by these recurring advisories, requiring a cautious approach to purchase regardless of the current pass status. At 180,524 miles on a 19-year-old platform, the vehicle accumulates approximately 9,500 miles annually, which aligns with expected usage patterns for its age and reflects moderate daily driving rather than extreme mileage burden. The six-month interval between the 2025 and 2026 MOT tests provides a brief window where the timing of inspections occurred irregularly, yet the progression of failures across different components indicates the car has been under regular scrutiny but continues to exhibit systemic issues. Notably, the 2023 failure introduced additional concerns including the offside position indicator and severe rear service brake binding, while the 2025 failure reappeared with the same core suspension problems plus new electrical and braking defects. The absence of any major subsystem failures in the most recent test does not negate the cumulative damage evident in the earlier records, particularly regarding suspension integrity and braking performance. Suspension linkages represent the primary mechanical concern, as both front and rear suspension arm pins and bushes have shown consistent signs of wear across the 2024 and 2025 tests, with the 2025 assessment specifically noting worn components on nearside and offside front arms. During a test drive, a buyer should listen for knocking or clunking noises when traversing uneven surfaces, as worn arm pins and bush seals often transmit vibration through the chassis. Additionally, inspect the rear suspension mounting points for any visible corrosion or looseness, as the 2026 advisory noted rear suspension component corrosion without serious structural weakness—a sign that rust may have progressed despite the lack of immediate failure. The front suspension should also be checked for play in the bushings and pins, particularly during cornering, where worn components can cause the wheel to pull outward or inward and produce a grinding sensation. Brake system reliability appears to be another critical area of concern, with three separate failures documenting binding rear service brakes and parking brake inefficiency. On test drive days, the driver should monitor the brake pedal for any sponginess or reduced firmness when approaching gentle decelerations, especially in the rear, as binding service brakes often manifest as a soft or pulsing pedal feel. A distinct grinding noise accompanied by vibration when applying the brakes could indicate warped discs or deteriorated pads, though the specific MOT advisories point more toward binding and hydraulic efficiency issues rather than pure wear. The offside position lamp failure is unrelated to mechanical function but represents a secondary safety issue that should be verified independently. Given the documented history of brake-related failures spanning nearly two years, any purchase should involve a thorough visual inspection of the brake lines, calipers, and master cylinder, with particular attention to the rear service brake assembly and parking brake mechanism before committing to ownership.
