2014 Ford S-MAX 1.6L Diesel · V17 SRB

Corrosion on the rear subframe and suspension arms represents the primary long-term mechanical concern for this vehicle, as these advisories have persisted or emerged in recent testing cycles. The most recent MOT on 22 May 2026 shows a pass, but it follows a failure for multiple lighting defects, including both front position lamps and registration plate lamps. While the subframe corrosion was noted as not seriously weakened during the May 2026 inspection, it follows a previous advisory in May 2024 regarding corrosion on both rear suspension arms. This indicates a developing trend of oxidation on the rear chassis and suspension components that requires close monitoring to ensure structural integrity is not compromised over time. The vehicle has covered 87,249 miles over its twelve-year lifespan, which averages to approximately 7,271 miles per year. This usage pattern is consistent with typical annual accumulation for a vehicle of this age and suggests a steady rate of wear on consumables such as tyres, brakes, and suspension bushings. There are no significant gaps in the testing history that would suggest long periods of stationary use, meaning the mechanical components have likely been subjected to regular, albeit moderate, operational cycles. A test drive should focus heavily on the rear suspension and chassis area due to the documented corrosion on the subframe and suspension arms. Listen for any rhythmic knocking, clunking, or heavy thudding sounds when driving over uneven surfaces or speed bumps, as these can indicate that the corrosion has progressed to the point of affecting the structural rigidity or the integrity of the suspension mounting points. Additionally, pay close attention to the steering response and any potential pulling to one side, particularly as the vehicle previously failed in May 2025 due to excessive play in the offside front track rod end ball joint. The history of lighting failures, specifically regarding the position lamps and registration plate illumination, suggests that electrical connections or bulb housings may be prone to issues. While these were rectified for the May 2026 pass, it is prudent to verify that all exterior lighting functions correctly during a physical inspection. Furthermore, the previous advisories regarding tyre cracking and perishing in 2022 should be cross-referenced with the current tread depth and sidewall condition to ensure that the rubber has not reached a state of advanced degradation despite the relatively moderate annual mileage.
