2017 Toyota Yaris 1.5L Hybrid electric (clean) · LL17 LSC

The most recent MOT test on the 2017 Toyota Yaris was passed on 2025-09-01, marking a return to compliance after a series of recurring issues that resulted in two failed tests within a year. The vehicle’s MOT history reveals a pattern of persistent brake disc wear and a persistent tyre pressure monitoring system (TPMS) malfunction, which failed twice in 2023 and once in 2024, alongside a recurring advisory on near-side rear shock absorber misting. While prior MOTs in 2022 and 2021 were clean, the 2023–2024 failures suggest either a gradual degradation in brake system performance or underlying mechanical wear that has not been fully addressed, particularly in the suspension and braking components. The advisories on brake discs indicate ongoing friction material and structural wear, which, if left unchecked, could lead to reduced braking efficiency or even disc failure over time. The TPMS failure is critical, as it compromises the vehicle’s safety by preventing accurate tyre pressure monitoring, increasing the risk of underinflation-related blowouts or excessive wear. The recorded mileage of 20,274 miles for a vehicle aged nine years represents a remarkably low annual mileage of approximately 2,253 miles, which is significantly below the average for its class. Such low usage typically reflects either infrequent driving, long periods of the vehicle being stationary, or a lifestyle that avoids high-mileage conditions. However, prolonged idling or infrequent use can exacerbate several mechanical issues, particularly in the braking and suspension systems. Standing vehicles are prone to brake disc corrosion, where moisture and road salt can cause rust buildup on the discs, leading to binding calipers or reduced braking performance. Similarly, suspension components like shock absorbers and bushings may degrade faster when not subjected to regular dynamic loading, as seen in the recurring misting advisory on the near-side rear shock absorber. The low mileage also means that consumables like brake fluid, coolant, and engine oil may have degraded over time due to prolonged exposure to heat and age, warranting careful attention to their condition. For a prospective buyer, the most pressing concerns stem from the persistent brake disc wear advisories and the TPMS failure, both of which must be addressed before purchasing. On a test drive, listen for uneven brake pedal travel or a spongy or pulsating feel, which could indicate warped discs or internal brake component failure. Inspect the brake discs visually for deep grooves, excessive pitting, or signs of rust, particularly on the edges where standing corrosion is most likely. The TPMS failure requires immediate replacement of the system, as the vehicle’s ability to monitor tyre pressure is essential for safety. Additionally, check for any fluid leaks around the brake master cylinder or caliper areas, as this could signal failing seals or hydraulic system issues. Beyond these, the near-side rear shock absorber misting suggests potential internal damage or seal failure, which may require further inspection for stability and ride quality. If the vehicle has been stationary for extended periods, verify the brake discs for corrosion by gently tapping them with a screwdriver—binding or grinding noises during braking would confirm binding calipers or seized components. In terms of broader physical checks, given the vehicle’s age and low mileage, focus on the following areas. First, examine the tyres for signs of sidewall cracking or perishing, which can occur even with low mileage if the vehicle has been left in direct sunlight or exposed to harsh environmental conditions. Check the tread depth for uniform wear, as uneven patterns may indicate suspension or alignment issues. Next, inspect the battery for signs of corrosion on the terminals and check its voltage with a multimeter to ensure it holds a charge, as older batteries in stationary vehicles often struggle to maintain power. The suspension should be tested for excessive clunking or rattling, particularly when driving over bumps, which could indicate worn suspension bushes or coil spring failure. Finally, since the vehicle has not been driven extensively, consider checking the fluid levels and condition of the engine oil, coolant, and brake fluid, as these fluids degrade over time even without significant mileage. If possible, review the service history for any scheduled fluid changes or component replacements, as this will provide insight into the vehicle’s maintenance record. A thorough inspection of the exhaust system for leaks or excessive noise is also advisable, as emissions-related issues could become problematic with age.
