2010 Toyota Yaris 1.3L Petrol · YT10 AAV

The latest MOT test results for this 2010 Toyota Yaris reveal a mixed but concerning maintenance trend. The vehicle passed the most recent MOT on 2026-08-05, yet it also failed major items—specifically, a non-functional near-side rear position lamp and an insecure front headlamp—which indicate a failure to address previous advisories and potential neglect in basic electrical and lighting maintenance. The presence of recurring corrosion advisories, particularly around the rear underbody, coil springs, and axle beams, suggests a pattern of structural and component degradation that has not been fully mitigated, despite passing previous tests. While the 2025 MOT was clean, the intervening years show persistent issues that may have worsened, particularly in the suspension and bodywork areas, where corrosion is a persistent risk for a vehicle of this age and mileage. The vehicle’s recorded mileage of 97,433 miles over approximately 16 years equates to around 6,090 miles annually, which is relatively moderate for a car of this age, though not exceptionally low. Lower mileage might suggest periods of inactivity or lighter use, which can exacerbate issues like standing corrosion, particularly in the underbody and wheel arches, where moisture and road salt accumulate. Conversely, higher-than-average mileage could imply more aggressive driving or frequent use in harsh conditions, accelerating wear on suspension components, brakes, and drivetrain elements. The absence of significant mileage spikes over the years does not entirely rule out hidden mechanical stress, however, as corrosion and component fatigue can develop subtly over time, even with steady usage. Given the recurring corrosion advisories and the recent MOT failures, the prospective buyer should prioritise a thorough inspection of the underbody, particularly focusing on the rear axle area, coil springs, and suspension mountings. Corrosion in these regions can compromise structural integrity, leading to potential failure of critical components such as the rear axle beam or suspension linkages. On a test drive, listen for unusual noises such as clunks or rattles from the rear suspension, which may indicate worn or failing bushes or springs. Additionally, check for uneven tyre wear patterns, which could signal misalignment or suspension issues, and inspect the brake system for signs of binding calipers or corrosion on discs and pads. If the rear position lamp and headlamp are non-functional, verify that wiring and connections are intact and that the bulbs are operational. For the buyer, the next steps should include a detailed mechanical and visual inspection beyond the MOT scope. Given the age and mileage, the vehicle may benefit from a full fluid service, including the brake fluid, coolant, and transmission fluid, as these can degrade over time, even without significant mileage. Inspect the tyres for signs of sidewall perishing, which can occur from age-related cracking, and ensure they meet the legal minimum tread depth. Check the 12V battery for signs of corrosion on terminals and overall health, as standing vehicles can suffer from battery drain or sulphation. Finally, verify that service records are up to date, particularly for the suspension and corrosion-prone areas, to confirm that any necessary repairs or treatments have been carried out. If the buyer is concerned about the persistent corrosion issues, they may also consider a professional corrosion treatment or underbody protection to extend the vehicle’s lifespan.
