2015 Ford Fiesta 1.0L Petrol · PL15 FSS

The most recent MOT test on the 2015 Ford Fiesta recorded a failure in February 2026, with critical issues including an ineffective near-side windscreen wiper system and a rear tyre with insufficient tread depth below the legal minimum of 1.6mm. This failure contrasts with the previous MOT in February 2025, which passed without any major defects, suggesting a deterioration in roadworthiness over the intervening year. The recurring oil leak advisory, present in multiple tests, indicates a persistent mechanical issue that requires immediate attention, as it may signal a failing oil seal or gasket, potentially leading to increased engine wear if unaddressed. The presence of minor and major faults in prior tests—such as fractured coil springs, worn brake pads, and swivel pin/bush wear—demonstrates a pattern of wear-related failures, particularly in the suspension and braking systems, which are critical for handling and safety. While the vehicle has not failed due to structural or emissions-related defects, the combination of these recurring advisories and failures highlights a need for proactive maintenance to prevent further degradation. The vehicle’s recorded mileage of 121,507 miles at the time of this assessment represents a reasonable annual usage rate of approximately 11,046 miles per year, which is typical for a 11-year-old Fiesta given its age and common ownership patterns. However, the mileage data alone does not account for potential periods of prolonged inactivity, which can accelerate wear in consumables like brake pads, tyres, and fluids, or exacerbate issues such as corrosion from standing. The suspension and braking systems, in particular, are subjected to cumulative stress from both mileage and static conditions, which may explain the observed wear on coil springs, brake discs, and swivel pin/bush components. A higher-than-average mileage accumulation could also suggest more aggressive driving or frequent use in demanding conditions, further straining components like the oil system and exhaust components. For a prospective buyer, the most critical areas to inspect during a physical examination and test drive are the suspension and braking systems, given the recurring MOT advisories and failures. Begin with a thorough check of the oil leak source, which could be located around the oil pan, valve cover, or oil filter housing. Listen for unusual noises during acceleration or deceleration, as these may indicate a failing oil seal or internal engine issues. Next, examine the front and rear brakes, focusing on the brake pads, discs, and calipers for signs of excessive wear, warping, or binding. On a test drive, observe for a spongy or pulsating brake pedal, which could signal warped discs or internal brake failure, and check for uneven brake pad wear or grinding noises, which may indicate metal-to-metal contact. The fractured coil spring observed in the 2025 MOT test suggests a severe failure in the rear suspension, which could lead to handling instability or a rough ride if not replaced. Inspect the rear axle swivel pins and bushes for excessive play or noise, particularly when cornering, as these components are critical for wheel alignment and suspension function. In addition to the mechanical checks above, the buyer should conduct a comprehensive inspection of the vehicle’s tyres, fluids, and general roadworthiness. Given the vehicle’s age and the near-side rear tyre failure in the latest MOT, verify the tread depth across all tyres, ensuring they meet the legal minimum of 1.6mm and are evenly worn. Check for signs of sidewall cracking or perishing, which can weaken tyre integrity and reduce safety. Inspect the battery and electrical systems, as prolonged standing can cause corrosion on terminals or a decline in battery health, leading to poor starting or electrical faults. The oil leak advisories suggest a need for a full oil change and filter replacement, as well as a check of the engine’s internal condition, including the timing belt (if applicable) and valve train components. Finally, verify the service history, particularly for the timing belt, suspension components, and brake system, as these are critical for long-term reliability. If the vehicle has been stored for extended periods, consider a thorough inspection of the exhaust system for corrosion or leaks, as well as the fuel system for signs of fuel degradation or contamination.
