2011 Ford Focus 1.6L Diesel · DP11 KUX

The maintenance trend for this 2011 Focus is worsening, with the December 2025 test at 127,989 miles revealing a growing list of structural and mechanical advisories. The tester flagged corrosion on both rear coil springs, a severely deteriorated offside front inner CV boot, and a fluctuating offside front service brake. A discoloured nearside front indicator also appeared. While the vehicle continues to pass, these defects point to aging components and deferred underbody maintenance rather than routine wear. Covering roughly 8,500 miles annually, the mileage accumulation aligns closely with the 15-year average for this vehicle. The recorded distance increased by 9,466 miles between the December 2024 and December 2025 tests, following a similar 8,909-mile jump the previous year. This consistent usage pattern suggests regular driving rather than prolonged standing, though the recent mechanical advisories indicate the previous owner did not reinvest that mileage into preventative repairs. A physical inspection must prioritize the vehicle's structural integrity and drivetrain. The recurring coil spring corrosion flagged in late 2024 and again in 2025 raises serious concerns about underbody rust, requiring a close examination of the chassis and suspension mounting points. The tester flagged the offside front inner CV boot as severely deteriorated in the most recent test, meaning joint contamination and imminent failure are likely. Buyers should also inspect the front brake discs, which were pitted and scored in 2022, alongside the fluctuating service brake noted in both 2024 and 2025. The repeated appearance of worn tyres close to the legal limit in 2023, combined with the persistent front brake issues, strongly suggests basic upkeep was skipped.
