2016 Ford Fiesta 1.5L Diesel · CV66 DYC

The 2016 Ford Fiesta passed its most recent MOT on 6 March 2026 at 92,520 miles, but the result reveals a worsening maintenance trend. The tester flagged a corroded front subframe, a corroded offside front brake pipe, a corroded nearside rear coil spring, and a badly corroded exhaust backbox. Both rear axle swivel pins and bushes were slightly worn, and a registration plate lamp was inoperative. These are not isolated minor advisories. The combination of structural corrosion on the subframe and a corroded brake pipe is a serious concern that directly affects braking integrity and long-term structural soundness. The vehicle is currently roadworthy, but the pattern suggests deferred maintenance is catching up. The mileage progression is broadly consistent with typical use for a ten-year-old car, averaging roughly 9,252 miles per year. The record shows 80,158 miles in September 2022, 86,217 miles in May 2024, 88,323 miles in February 2025, and 92,520 miles in March 2026. There are no alarming gaps or sudden spikes in accumulation. The annual mileage has remained steady, which means the wear on suspension, brakes, and the exhaust system is proportionate to use rather than neglect through low mileage. The 2022 failure for a worn offside front suspension arm ball joint and two worn tyres, followed by a clean pass in 2024 with only brake pads and a lamp flagged, suggests basic consumable upkeep was maintained. The jump in flagged defects by March 2026, however, indicates the car has entered a phase where age-related corrosion is now outpacing routine maintenance. A buyer should inspect the front subframe and the offside front brake pipe in person without delay. Corrosion on a subframe is a structural issue that can compromise suspension mounting points and handling stability. A brake pipe described as corroded and covered in grease or other material raises the question of whether the corrosion is active and whether the pipe has been temporarily masked rather than properly replaced. The corroded nearside rear coil spring is another structural risk, as a weakened spring can fracture under load, causing sudden suspension collapse. The badly corroded exhaust backbox is less critical mechanically but confirms that corrosion is widespread underneath the car. The rear axle swivel pin and bush wear, while only slight, points to aging suspension components that will need monitoring or replacement. Given the concentration of corrosion-related defects in the most recent test, a buyer should arrange an independent inspection focused on the underside, particularly the subframe, brake lines, and suspension mounting points. The MOT record shows the car has been maintained well enough to pass consistently, but the March 2026 result marks a clear shift from minor wear items to structural and safety-critical corrosion that demands immediate attention.
