2009 Ford Fiesta 1.2L Petrol · KU59 YWS

Corrosion on the rear subframe and deteriorating drive shaft components represent the primary mechanical concerns for this vehicle, as evidenced by the most recent MOT pass on 10 June 2025. While the vehicle has passed its most recent inspection, the advisory regarding subframe corrosion and the recorded deterioration of the nearside front outer drive shaft CV boot indicate emerging issues with structural integrity and drivetrain components. The testing history shows a fluctuating pattern of roadworthiness, with significant failures recorded in 2021 and 2023 involving brake efficiency, exhaust emissions, and suspension linkages, though the 2024 and 2025 results show a period of passing without major defects. The recorded mileage of 120,236 miles over approximately 17 years equates to an average annual usage of roughly 7,073 miles. This represents a typical usage pattern for a vehicle of this age, suggesting consistent, moderate road use rather than long periods of stationary storage or high-intensity motorway driving. Mechanically, this level of accumulation implies that while the engine may not have excessive mileage, wear on consumable items such as suspension bushes, brake discs, and various rubber seals and boots is consistent with the vehicle's age and service life. A prospective buyer should pay close attention to the chassis and suspension during a physical inspection and test drive. The advisory for rear subframe corrosion necessitates a close examination of the metal for any signs of significant scaling or perforation, as this component is vital for structural stability. On the road, you should listen for any knocking or clunking noises from the underside, particularly when driving over uneven surfaces or speed bumps, which could indicate that the previously failed suspension ball joints or anti-roll bar linkages have developed new play. Furthermore, the deteriorating nearside front CV boot may eventually lead to audible clicking sounds when turning the steering wheel at low speeds, a symptom of grease loss and joint wear. Braking performance and drivetrain smoothness also require scrutiny. Given the advisory for worn front brake discs and the historical failure regarding low brake efficiency in 2021, you should test the pedal feel for any sponginess or judder under braking. Any pulling to one side or uneven deceleration should be investigated. Additionally, because the drive shaft CV boot is noted as severely deteriorated, you should monitor for any vibrations through the steering wheel or floorpan during acceleration, which could signal that the drive shaft joint is beginning to fail.
