2023 Ford Fiesta ST-Line Edition T Mhev 1.0L Petrol · YA72 WNF

The latest DVSA MOT test for the 2023 Ford Fiesta ST-Line Edition T MHEV recorded a failure on 2026-01-10, specifically for a major defect under section 5.2.3(b): the presence of near-side front tyres of differing sizes on the same axle. This marks a clear deviation from the vehicle’s original specification and represents a critical roadworthiness issue, as mismatched tyres can lead to uneven wear, compromised handling dynamics, and increased risk of hydroplaning or loss of traction. The previous MOT test on the same date, though also recorded as failed, was not repeated, suggesting either a one-off anomaly or a potential oversight in the testing procedure. For a buyer, this single failure indicates a need for immediate rectification before any further assessment of the vehicle’s overall mechanical condition can proceed, as the tyre mismatch alone poses significant safety implications during operation. The recorded mileage of 27,658 miles for a vehicle aged just over three years reflects a usage rate of approximately 9,219 miles annually, which is relatively typical for its class and age. This level of mileage does not suggest excessive wear beyond what is expected from normal driving conditions, though it does imply that the car has been in active use rather than standing idle for extended periods. However, without additional context on whether the mileage accumulation was gradual or sudden, it is impossible to definitively assess wear progression on consumables such as brake pads, suspension components, or drivetrain elements. A higher-than-average mileage in a short timeframe could indicate more aggressive driving habits, which may accelerate wear on components like suspension bushes, coil springs, or exhaust systems, potentially leading to premature failure if not serviced regularly. Conversely, if the mileage was accumulated over a longer period, the vehicle may have been subjected to less stress, but this would require further inspection to confirm. Given the critical tyre mismatch failure, the immediate priority for the prospective buyer is to address this defect before proceeding with any further evaluation. The near-side front tyres must be replaced with tyres of identical size and specification to ensure proper load distribution, handling stability, and compliance with legal requirements. During a test drive, any signs of uneven tyre wear—such as lateral grooves, tread depth discrepancies, or excessive shoulder wear—would further confirm the need for replacement. Additionally, the buyer should inspect the vehicle’s suspension for associated wear, particularly around the front axle, as mismatched tyres can exacerbate issues with coil springs, shock absorbers, or strut mounts. Beyond the tyre issue, the buyer should also verify that the vehicle’s service history aligns with Ford’s recommended maintenance schedule, particularly for fluid changes (oil, coolant, brake fluid) and component replacements (timing belt, water pump, spark plugs) that may have been deferred due to the MOT failure. For a vehicle of this age and mileage, assuming the tyre mismatch is resolved promptly, the buyer should conduct a thorough physical inspection to address potential issues related to both mileage and standing time. Given the relatively low annual mileage, the vehicle may have been exposed to standing corrosion, particularly around the wheel arches, undercarriage, and brake components, where moisture and road salt can accelerate rust formation. The buyer should check the brake discs and calipers for signs of corrosion or binding, as prolonged standing can cause brake fluid to degrade or seals to dry out, leading to reduced braking performance. Additionally, the 12V battery should be tested for capacity and terminal cleanliness, as extended periods without use can result in reduced charge retention or internal corrosion. For fluid systems, the buyer should consider the calendar-based degradation of fluids such as coolant, transmission fluid, and differential oil, even if the vehicle has not been driven extensively. A check of the service book or receipts for the timing belt replacement, which is critical for the MHEV system’s longevity, would also be prudent, as this component often requires replacement at around 100,000–120,000 miles or every 6 years, whichever comes first. Finally, the buyer should ensure that the exhaust system is free of leaks or excessive backpressure, which could indicate catalytic converter or manifold wear, especially if the vehicle has been driven regularly.
