2005 Ford Mondeo 2.0L Diesel · KD55 ASX

The vehicle currently holds a valid MOT following a pass on 27 January 2026, but the maintenance trend shows signs of sudden structural deterioration. While the car passed clean tests in late 2023 and late 2024, a significant failure occurred on 09 January 2026 at 158,276 miles. The tester identified excessive corrosion on the nearside rear suspension component mounting area, which significantly reduced its structural strength. Although the subsequent pass indicates this specific structural defect was rectified, the emergence of such serious corrosion on a 21-year-old vehicle suggests that the chassis and subframe integrity may be under threat. The mileage accumulation appears consistent with the vehicle's age, averaging approximately 7,500 miles per year. The records show steady progress from 147,513 miles in November 2022 to 158,276 miles in January 2026. This gradual increase suggests regular, predictable use rather than long periods of inactivity or heavy commercial usage. The data provides a reliable longitudinal view of the car's life, though the recent jump in mechanical issues contrasts with the relatively stable mileage pattern. A prospective buyer must conduct a thorough physical inspection of the underbody, specifically focusing on the rear suspension mounting points and the surrounding subframe. The January 2026 failure for structural corrosion is a serious indicator that surface rust may be progressing into deeper, more systemic issues. You should check for signs of recent welding or heavy-duty corrosion protection treatments in the rear arches and suspension wells to ensure the repair was permanent and high quality. The November 2022 test highlighted multiple worn tyres and thinning brake discs, which are standard consumable wear items for a vehicle of this age. While these were resolved by the 2023 and 2024 tests, you should verify the current condition of the braking system and tyre tread depths. Pay close attention to the rear brake components and suspension bushes, as the previous advisory regarding brake disc wear combined with the recent structural failure suggests the rear assembly has been a recurring area of concern.
