2017 Ford Fiesta 1.0L Petrol · YA17 PVY

The most recent MOT test on 2025-09-08 confirms the vehicle passed with no defects recorded, though the preceding failure on 2025-07-03—just 119 miles before the retest—raises immediate concern. The pattern of two consecutive failures in early 2025, followed by a clean pass in March 2024, suggests inconsistent or rushed maintenance rather than a worsening mechanical trend. The lack of advisories or defects in any test implies no recurring structural issues, but the repeated failures within months of each other indicate either a test centre error, a minor but persistent fault (such as a misaligned sensor or minor emission leak), or a lack of pre-MOT servicing. The latest pass is only 10 months old, which is acceptable, though the irregularity in the 2025 window warrants closer scrutiny of service records. The recorded mileage of 43,715 miles over nine years equates to approximately 4,857 miles annually, a figure significantly lower than the UK average for a vehicle of this age. The gap between the March 2024 test (35,768 miles) and the January 2025 failure (42,110 miles) represents roughly 6,342 miles in under a year, suggesting either a period of heavier use or an inaccurate odometer reading. The subsequent 526 miles between the January 2025 failure and pass—covered in just 36 days—implies the vehicle was driven sporadically rather than continuously. This low-mileage pattern may mean the car has spent extended periods stationary, potentially accelerating corrosion risks in suspension components, wheel arches, and underbody panels. Given the lack of recorded defects, the most critical areas for an in-person inspection should focus on components commonly overlooked in low-mileage vehicles. The repeated failures in early 2025, despite no defects being logged, suggest a potential issue with the vehicle’s emissions system—likely the lambda sensor, catalytic converter, or exhaust gas recirculation (EGR) valve—which can fail intermittently without obvious physical signs. The suspension should be checked for worn or leaking rubber bushes, particularly on the rear, as these degrade more rapidly when a vehicle sits for prolonged periods. Brake discs and pads, while not explicitly failed in tests, should be inspected for uneven wear or binding calipers, which could explain the retest after minimal mileage. Finally, examine the underbody for corrosion, especially around the sills, wheel arches, and exhaust system, as standing water accelerates rust in critical structural areas.
