2010 Ford Fusion 1.4L Diesel · WF10 YKJ

The 2010 Ford Fusion presents a mixed maintenance trend, resolving immediate electrical and visibility failures but leaving structural corrosion and persistent tyre perishing unaddressed. In the July 2025 test at 35,226 miles, the tester flagged corrosion on both rear coil springs and perishing on three tyres. The vehicle failed the initial attempt that same day due to ineffective wipers and incorrect rear indicator colours, passing only after these specific items were rectified. This indicates a reactive maintenance pattern rather than proactive component renewal. Accumulating just 35,226 miles over sixteen years equates to roughly 2,202 miles annually, confirming exceptionally light usage. The mileage progression shows steady, minimal increments between tests, with no sudden spikes or suspicious gaps suggesting long periods of total inactivity. Such low mileage typically preserves drivetrain components, yet the vehicle's age and standing time have taken a visible toll on rubber and suspension elements. A physical inspection must prioritise the rear suspension and underbody condition. The tester repeatedly flagged corrosion on both rear coil springs, a serious structural risk that demands close scrutiny for pitting or reduced spring integrity. Persistent tyre perishing across multiple test dates suggests the rubber is degrading due to age and standing, requiring immediate replacement regardless of remaining tread depth. Buyers should also examine the engine sump for the previously noted oil leak and assess the rear exhaust silencer, which showed deterioration in 2022. The 2023 advisory regarding a lazy nearside front service brake and imbalance warrants a thorough check of the braking system for seized calipers or uneven disc wear.
