2009 Toyota Yaris 1.0L Petrol · DN58 FSP

The most recent MOT test, conducted on 2025-10-22, resulted in a pass with two persistent advisories: underbody corrosion and front sub-frame corrosion that does not significantly compromise structural integrity. However, the vehicle’s MOT history reveals a pattern of recurring issues, particularly with the rear suspension and mounting components, which have been flagged as corroded or defective in multiple tests. The failure on 2025-10-21 stands out as a critical outlier, where both rear shock absorbers exhibited serious fluid leaks and the offside rear wheel bearing was found to be rough when rotated, indicating severe mechanical wear and potential bearing failure. While earlier tests show some improvements with advisories being downgraded from major to minor or removed, the underlying corrosion and suspension wear suggest a vehicle that has not been fully maintained to prevent progressive deterioration. The combination of these failures and advisories indicates a vehicle that is approaching critical mechanical thresholds, particularly in the suspension and underbody systems, where corrosion and fluid leaks are exacerbating component failure. The recorded mileage of 85,222 miles for a vehicle aged approximately 17 years represents a relatively low annual usage rate of around 5,013 miles per year, which is notably below the average for its class. Such low mileage can sometimes reflect periods of prolonged inactivity, particularly if the vehicle has been stored or used infrequently, leading to accelerated wear from standing corrosion rather than mechanical stress. However, the consistency of corrosion-related advisories across multiple MOT tests suggests that the vehicle has been exposed to environmental conditions that accelerate rust formation, such as prolonged exposure to damp or salted surfaces. The lack of higher mileage accumulation does not necessarily mitigate the risk of corrosion-related failures, as standing corrosion can compromise structural integrity without the dynamic wear that higher mileage might otherwise provide. Buyers should be cautious, as the combination of low usage and persistent corrosion indicates a vehicle that may require more frequent and thorough maintenance to address the underlying issues before they escalate into major mechanical failures. Given the vehicle’s MOT history and the recurring advisories, the prospective buyer should prioritise a thorough mechanical inspection before purchase. Focus on the rear suspension components, particularly the shock absorbers, which have failed due to fluid leaks and bearing wear. During a test drive, listen for unusual clunking or rattling noises from the rear suspension, especially when transitioning between rough and smooth surfaces, as this may indicate loose or failing components. Additionally, check for uneven tyre wear patterns, which could signal misalignment or suspension issues. The wheel bearings should be inspected for excessive play or grinding noises, particularly on the offside rear wheel, as this was a major failure point in the 2025 test. The front suspension, including the Macpherson strut and anti-roll bar linkage, should also be examined for signs of corrosion or binding, with particular attention to the ball joints, which were already compromised in a previous MOT. Beyond the mechanical checks, visually inspect the underbody for any signs of rust progression beyond the advisories noted, as this may reveal areas of structural compromise that could not be fully assessed during the MOT. If possible, obtain a pre-purchase inspection from a qualified mechanic to confirm the severity of the corrosion and suspension damage, as these issues may require costly repairs or replacement parts. For a vehicle of this age and mileage, the buyer should also address practical checks that are particularly relevant to its usage profile. Given the low annual mileage, the vehicle may have experienced prolonged exposure to static conditions, leading to issues such as brake disc corrosion or binding calipers due to standing. Inspect the brake system for any signs of corrosion on the discs, particularly on the offside rear where previous advisories suggest potential issues, and check for excessive brake pedal travel or sponginess, which could indicate fluid degradation or air in the hydraulic system. The fuel filler neck and associated components have been repeatedly flagged for corrosion, so visually inspect the neck and filler cap for rust or cracks, and ensure the fuel system is free of leaks or blockages that could affect performance. The battery should be tested for voltage and capacity, as low usage can lead to diminished battery health, and the alternator should be checked for proper charging output to prevent electrical system failures. Finally, given the vehicle’s age, the fluid levels—particularly the engine oil, brake fluid, and coolant—should be topped up or replaced according to manufacturer recommendations, as fluids degrade over time even with low mileage. Service records should be reviewed to confirm that scheduled maintenance, such as oil changes and suspension servicing, has been completed, as this will provide a clearer picture of the vehicle’s maintenance history and help mitigate future costs.
