2018 Toyota Yaris 1.5L Petrol · SC18 BAU

The 2018 Toyota Yaris received its latest MOT on 2026-03-02, where it passed with three advisories—two relating to the offside rear suspension ball joint exhibiting slight play and the rear wheel bearing showing minor noise, alongside a nail embedded in the offside rear tyre. While the vehicle has otherwise maintained a clean MOT record since 2023, the presence of these recurring advisories suggests a gradual wear pattern in the suspension components, particularly the rear ball joint and wheel bearing. The failure in 2024-08-16—where the offside rear tyre was deemed unsafe due to a deep cut reaching the ply and significant cracking—indicates that the tyre wear and structural integrity issues have not been fully resolved, and the vehicle’s roadworthiness may be compromised if these defects are not addressed promptly. This trend, combined with the consistent advisories, implies that the vehicle’s maintenance history has not been entirely proactive, leaving potential long-term risks if the suspension and tyre issues are not rectified. The recorded mileage of 54,984 miles for a vehicle aged eight years represents a moderate annual usage rate of approximately 6,873 miles per year, which is within the expected range for this model’s class. However, the gap between the 2024 failure and the 2026 MOT—nearly two years—could suggest periods of prolonged stationary use, which exacerbates wear on components like wheel bearings, suspension bushes, and tyres. Standing vehicles are particularly vulnerable to corrosion in brake discs, caliper seals, and suspension linkages, as well as tyre perishing from exposure to elements. Additionally, if the mileage accumulation was higher in recent years, it would accelerate wear on consumables such as brake pads, clutch components, and engine fluids, though the current data does not indicate rapid mileage accumulation. The absence of service records or a service booklet would mean the buyer should prioritise verifying the vehicle’s fluid levels and condition, as well as checking for any signs of fluid degradation over time. Given the advisories and failure history, the prospective buyer must conduct a thorough mechanical inspection before purchase. Focus on the offside rear suspension ball joint and wheel bearing, as the slight play and noise suggest impending failure. During a test drive, listen for clunking noises from the rear suspension when cornering or over bumps, and check for excessive wheel wobble or vibration that could indicate a failing bearing or misaligned wheel. Inspect the offside rear tyre for any signs of further damage, such as cracks, bulges, or uneven wear patterns, as the previous MOT failure highlights the severity of tyre degradation. Additionally, visually inspect the rear wheel assembly for leaks around the wheel bearing housing or signs of corrosion, and ensure the tyre pressure is within specification to mitigate further wear. For the remaining components, the buyer should verify the condition of the front tyres, as the 2021 MOT noted wear close to the legal limit, which could lead to a repeat failure if not addressed. Check for sidewall cracking or perishing, which is more likely in a vehicle of this age and mileage, particularly if it has been stationary for extended periods. Inspect the brake system for signs of corrosion on the discs or binding calipers, which can occur when the vehicle stands for long durations without use. Test the brake pedal for firmness and ensure there is no pulsation or shuddering, which could indicate warped discs or soft brake pads. Finally, given the vehicle’s age and potential stationary periods, examine the 12V battery for signs of weakness or corrosion, and confirm that all fluids—oil, coolant, brake fluid, and transmission fluid—are topped up and free from contamination. If no service history is available, consider scheduling a professional fluid flush to address any calendar-based degradation.
