2010 Ford Fiesta 1.4L Diesel · W66 NAD

A pattern of underbody and front-end corrosion combined with deteriorating steering and braking hardware defines the mechanical profile of this 2010 Ford Fiesta, making it a vehicle that demands close physical inspection before purchase. The 2025-01-23 test recorded a Pass but flagged a corroded front subframe as an advisory, and this sits alongside a 2024-10-04 failure that included a Dangerous defect for an offside front anti-roll bar linkage ball joint likely to become detached, a Major defect for excessive play in the nearside front track rod end ball joint, and Major defects for excessively corroded brake pipes on both the nearside rear and offside front. The recurrence of oil leak advisories on the front of the engine from both 2022 and 2025 further suggests chronic front-seal or sump-gasket seepage. Taken together, the trend from 2022 through 2025 shows a clear deterioration in structural and safety-critical components rather than a stable or improving roadworthiness picture, and any prospective buyer should treat the most recent Pass with significant caution given the severity of the items flagged roughly three months earlier. At 80,322 miles over sixteen years, this Fiesta has covered approximately 5,020 miles annually, which is below the typical mileage band for a car of this vintage and indicates either extended periods of light use or significant standing time between journeys. A noticeable gap exists between the 2022-10-11 test and the 2024-10-04 failure, during which the vehicle does not appear to have been presented for testing, and this interval combined with the low overall annual mileage raises the possibility that the car was either off the road or used sparingly. Mechanically this profile typically results in aged rubbers, seized caliper slide pins, crystallised brake fluid, and corrosion advancing on components that rely on regular thermal cycling and movement to shed surface rust. The 2024 brake pipe failures and subframe corrosion advisory are consistent with the sort of underbody oxidation that accelerates during periods of damp standing followed by short, infrequent trips. For the anti-roll bar linkage and track rod end, on a test drive listen for clonking or rattling from the front suspension over speed humps, uneven bumps, and rough tarmac, and feel for vagueness or delay in steering response particularly when turning into corners at low speed. Excessive free play in the steering before the front wheels respond, or a knocking transmitted through the wheel during full-lock manoeuvres, would suggest the anti-roll bar joint or track rod end has deteriorated beyond the 2024 condition. Visually inspect the front anti-roll bar drop links and ball joints for perished or split dust boots, grease contamination, and any obvious vertical movement in the joint when the wheel is levered with the car raised. For the brake pipes, crouch beneath the car and run a gloved hand along the nearside rear and offside front lines looking for flaky, blistered, or pitted steel, particularly where the pipe passes near the subframe, fuel lines, or body mounting points, as these are the locations where corrosion is most aggressive. The subframe corrosion advisory from 2025 and the general underbody condition warrant a thorough examination on a ramp or over an inspection pit, focusing on the front subframe mounting points, the rear axle beam, and the suspension strut towers for any flaking that has progressed beyond surface oxidation. The front oil leak advisories from both 2022 and 2025 suggest the engine has been seeping consistently, so check for fresh oil residue on the lower crankcase, sump plug, and bellhousing, and ask whether the level requires regular top-ups between services. Finally, with the 2024 seat adjustment mechanism failure, confirm that the driver's seat locks firmly in position and does not slide fore and aft under braking, as the failure suggests the recliner or runner mechanism was either stripped or seized at the time of test and may not have been properly rectified.
