2015 Ford Fiesta 1.5L Diesel · FD65 CZH

The maintenance trend for this Fiesta is worsening, driven by deteriorating suspension components and exhaust emissions. The most recent test in October 2025 passed at 124,795 miles, yet this followed a failure the previous day for missing rear seatbelts and excessive black smoke. The tester flagged an advisory for light oil misting on the offside rear shock absorber during the pass, indicating a persistent leak that requires monitoring. A fractured offside rear coil spring caused a failure in October 2024, and while the vehicle passed the following year, the recurring suspension issues suggest ongoing wear rather than a comprehensive repair. Accumulating 124,795 miles over eleven years equates to roughly 11,345 miles annually, a typical figure for this age of vehicle. The mileage progression shows consistent use without prolonged periods of inactivity. Between October 2024 at 116,904 miles and October 2025 at 124,795 miles, the vehicle covered 7,891 miles, confirming regular recent use. This steady accumulation places predictable wear on consumables and drivetrain components, though it does not explain the severe emissions failures. A buyer must inspect the offside rear suspension thoroughly. The history reveals a broken coil spring in 2024 and an active oil misting advisory on the shock absorber in 2025, raising concerns about structural integrity and damper effectiveness. The severe black smoke and failed emissions test in October 2025 point directly to a compromised diesel particulate filter or poor engine combustion, demanding a diagnostic scan and a thorough exhaust inspection. Missing rear seatbelts and buckles on the day of the 2025 failure suggest potential interior neglect or damage, so checking the rear belt mechanisms and anchorages for proper operation is essential.
