2018 Toyota Yaris 1.5L Hybrid electric (clean) · LS18 OPD

The most recent MOT test on the 2018 Toyota Yaris was conducted on 2026-02-18 and resulted in a clean pass, marking a positive turnaround following a series of failures and advisories in the preceding year. While the vehicle has not yet faced a defect in the past six months, the history reveals a pattern of recurring issues that warrant cautious optimism. The failure in May 2025—particularly the offside rear wheel bearing roughness—suggests underlying wear that may have been exacerbated by prolonged operation before the test, indicating that the bearing could be approaching critical failure if not addressed promptly. The nearside front tyre warning, noted in both May 2025 and January 2022, underscores the importance of monitoring tyre wear progression, especially given the edge wear pattern, which often signals misalignment or incorrect tyre pressure. These recurring advisories imply that the vehicle’s alignment or suspension geometry may have been neglected, leading to uneven tyre wear and potential long-term structural stress on the wheel bearings and suspension components. The recorded mileage of 49,281 miles for an eight-year-old Yaris reflects a moderate annual usage rate of approximately 6,160 miles per year, which is within the expected range for a vehicle of this age and class. Lower mileage could suggest periods of inactivity or light use, potentially leading to issues such as standing corrosion on the chassis, degraded brake discs or calipers from prolonged idling, or fluid degradation in the cooling, brake, and transmission systems. Conversely, higher mileage would imply greater wear on consumables like brake pads, suspension bushes, and drivetrain components, but the current mileage does not suggest extreme overuse. The absence of significant gaps in the MOT history, aside from the recent stability, implies that the vehicle has been regularly tested, though the past failures highlight the need for proactive maintenance rather than reactive repairs. For the prospective buyer, the most critical areas to inspect are the rear wheel bearings and suspension components, given the history of fluid leaks and roughness. On a test drive, listen for unusual noises from the rear axle, such as grinding or clunking when accelerating or braking, which could indicate bearing failure or misalignment. Check for excessive play in the wheel bearings by gently rotating the wheel while applying pressure to the wheel hub—any excessive movement or vibration signals imminent failure. The nearside front tyre wear advisories suggest verifying tyre alignment and ensuring correct tyre pressures to prevent further uneven wear. Additionally, inspect the rear tyres for signs of cracking or perishing, as noted in previous MOTs, particularly around the shoulder areas where the cracks were observed. If the tyres are still in good condition but show signs of age-related perishing, consider replacing them before they reach the legal limit, as cracked rubber can compromise handling and safety. Beyond the mechanical checks, the buyer should also examine the vehicle’s standing condition for signs of corrosion, particularly around the wheel arches, underbody, and brake components, which are prone to rust when stationary for prolonged periods. Check the brake discs for corrosion or binding, which can occur if the vehicle has been left unused for extended periods, leading to brake fluid absorption and system stiffness. Inspect the 12V battery for signs of weakness, such as slow cranking or electrical gremlins, as older vehicles are more susceptible to battery failure due to internal degradation. For fluids, focus on the brake, coolant, and transmission fluids, which should be replaced according to Toyota’s service schedule—typically every 60,000 to 100,000 miles or every two years, whichever comes first. Verify that the service book is up to date, as missing or outdated service records can indicate neglect in critical areas like oil changes, spark plug replacements, and suspension servicing. Lastly, ensure the exhaust system is free of leaks or disconnections, as emissions-related issues were not flagged in the MOT history, but a visual inspection is prudent to confirm compliance with current regulations.
