2010 Ford Focus 2.5L Petrol · ST59 TON

A pattern of recurring safety and drivetrain defects defines the mechanical narrative of this 2010 Ford Focus. Across seven recorded MOT tests since 2021, the vehicle has been presented with a mix of advisories and failures that warrant scrutiny. The most recent test on 23 January 2026 returned a clean pass with no defects recorded, but this follows a 2025 failure involving a split near-side front inner CV boot and an inoperative engine management MIL lamp, alongside a 2024 failure where both rear anti-roll bar linkage ball joints were recorded as excessively worn and the rear registration plate was missing. Two MOT cycles (2024 and 2025) included advisories for fraying on the near-side rear seat belt webbing, an item that has now persisted across three consecutive tests. The overall trajectory shows intermittent major defects rather than progressive deterioration, but the clustering of suspension, drivetrain, and emissions-related issues within a short window suggests that components are reaching a stage where age-related wear is becoming more frequent. At 71,599 miles over approximately sixteen years, this Focus has covered an average of around 4,475 miles annually, which is notably below the typical accumulation rate for a vehicle of this vintage. Such low usage can mean reduced wear on major drivetrain components but also raises the possibility of extended standing periods, where rubber components, lubricants, and braking surfaces can deteriorate through inactivity rather than use. The MOT testing record shows no multi-year gaps, indicating the vehicle has been presented consistently each year, so there is no evidence of a long-term off-road lay-up. However, buyers should be mindful that low annual mileage does not insulate a Focus of this age from corrosion, particularly in the rear subframe, sill, and wheel arch areas which are known weak points on this generation. Given the specific defects recorded, particular attention should be paid to the suspension and drivetrain during any inspection. The 2024 failure for both rear anti-roll bar linkage ball joints being excessively worn suggests that the bushes and drop links across the rear axle should be checked for play by hand, and any knocking or clunking over uneven surfaces or during direction changes would indicate that further components have reached the end of their service life. The 2025 CV boot failure on the near-side front inner drive shaft joint is a common Focus issue, and any clicking on full lock, vibrations under acceleration, or fresh grease around the joint area should be treated as a warning. The persistent rear seat belt webbing fraying is also worth physically inspecting, as frayed webbing compromises the load-bearing integrity of the restraint and may require replacement rather than a simple retension. The inoperative MIL lamp failure from 2025 is a separate concern that deserves careful investigation. A lamp that fails to illuminate when it should, or that remains on continuously without a stored fault, can mask underlying engine management or emissions faults. Before purchase, any warning lights should be verified as operating correctly and the ECU scanned for stored diagnostic trouble codes, even if the car appears to run normally. On a test drive, listen for irregular idle, hesitation under load, or any flat spots in throttle response, and check for excessive smoke from the exhaust. Given the age of the vehicle, an inspection underneath the car for corrosion around the rear subframe mounting points, brake pipe corrosion, and exhaust integrity would be prudent, as these are areas that may not have been captured in the MOT history but are consistent failure points for this model.
