2015 Ford Fiesta 1.0L Petrol · FP15 XVM

The mechanical profile of this 2015 Ford Fiesta is shaped by a cluster of rear suspension wear advisories and a single failure event in early 2023, with the most recent assessment on 26 January 2024 returning a clean pass. The January 2023 test failed on three separate Major defects: a non-functional horn, an exhaust lambda reading outside specified limits following the second fast idle, and an inoperative offside stop lamp. These are individually disparate items rather than symptoms of a single underlying failure, which is consistent with a vehicle that had perhaps been subject to deferred maintenance at that point. Notably, the same test also recorded advisories on both the offside and nearside rear suspension arm pins or bushes showing wear without excessive play, which suggests a developing pattern of degradation in the rear suspension geometry that warrants close physical inspection before purchase. Mileage stands at 75,884 miles across an 11-year lifespan, equating to approximately 6,899 miles annually, which is broadly typical for a car of this age and class. There is a reasonable density of testing activity between 2022 and 2024, with four recorded tests across that period, indicating the vehicle has been in regular use and not subject to extended off-road lay-ups. This level of consistent usage is mechanically beneficial, as it tends to prevent the drying and cracking of rubber components, the seizure of brake calipers, and the degradation of exhaust fittings that often afflict low-mileage or stored vehicles. The mileage accumulation between tests is also unremarkable, with no sudden spikes that might suggest heavy commercial use or extended motorway commuting, both of which can accelerate wear on specific components differently. The advisories recorded on both rear suspension arm pins or bushes are the most important items to investigate physically, as these are common wear points on the Fiesta platform and can progress to play in the rear axle location if left unaddressed. On a test drive, pay close attention to any clonking or knocking from the rear axle over uneven surfaces, any wandering or instability of the rear end during direction changes, and any uneven or premature wear on the inner edges of the rear tyres, which can indicate geometry disturbance from worn bushes. A useful diagnostic is to physically push the rear of the car sideways while it is parked, feeling for any knocking or free play at the hub, and to inspect the bushes visually for cracking, splitting, or signs of fluid leakage from associated components. Given the exhaust lambda failure and stop lamp defect recorded at the 2023 test, it is prudent to verify that the exhaust system is currently free of leaks, that the oxygen sensor and catalytic converter are functioning correctly via a live diagnostic read, and that all stop lamps, including the high-mounted third lamp, illuminate correctly under both light and heavy brake pedal applications. The horn defect is unlikely to recur but should be confirmed operational. Additionally, inspect the condition and quality of the rear brake components, as the suspension wear noted can accelerate uneven pad and disc wear, and check the rear tyres for any inner-edge wear patterns that would confirm the suspension advisory has progressed since the last recorded inspection.
