2015 Ford Focus 1.6L Diesel · LB15 LRN

A clear pattern of rear suspension and chassis corrosion advisories has emerged across the most recent two MOT tests for this 2015 Ford Focus, with the July 2026 test recording both rear suspension arms and the rear axle itself as corroded but not seriously weakened. This deterioration at the rear follows a related set of advisories from July 2025, where the nearside and offside rear axle swivel pins and bushes were noted as slightly worn, suggesting a progressive wear or corrosion issue developing in the rear beam and its mountings. The front brake pads have also been flagged as wearing thin at three of the last four tests, indicating a steady and ongoing consumption of friction material that warrants measurement at the next service. The intervening failure on 7 July 2025 was issued without any new major or dangerous defect recorded, so the underlying cause of that single failure is not specified in the history provided. Prior to 2025 the record was unblemished, with passes in 2022, 2023, and 2024 returning no advisories whatsoever, meaning the mechanical decline has been concentrated within the last twelve to twenty-four months rather than spread evenly across the vehicle's life. The earlier 2022 failure was solely attributable to a tyre pressure monitoring system malfunction, which is a comparatively minor electronic item that can often be resolved through re-initialisation or sensor replacement. The recorded mileage of 88,018 miles spread across roughly eleven years equates to an average annual accumulation of around 8,000 miles, which sits within the typical range for a privately used family hatchback of this age. There are no conspicuous gaps between test dates and no extended periods off the road that would suggest long stationary lay-ups, with tests appearing almost annually since 2021 and mileage progressing steadily. The annual mileage figure is sufficient to ensure that mechanical components have been regularly worked, which is generally kinder to consumables like brake discs, clutch material, and drivetrain bearings than very low annual mileages combined with short urban trips. However, at this mileage band items such as wheel bearings, suspension bushes, water pump, and exhaust mountings commonly reach the end of their intended service life, so the recent advisory activity should be read against that backdrop rather than treated as exceptional. For a prospective buyer, the rear axle and suspension arm corrosion advisories from July 2026 are the single most important area to scrutinise. The rear beam, its mounting bushes, and the trailing arm pivots on this generation of Focus are known corrosion traps, and an MOT advisory of not seriously weakened implies that perforation or weakening could realistically occur by the next test twelve months later. On a test drive, listen for clonking or knocking noises from the rear over uneven surfaces, particularly single-bump compression, and feel for any vagueness or wandering from the rear axle under load. With the vehicle unloaded and stationary, a second person should gently push each rear wheel from behind to detect play in the stub axle bushes; any noticeable vertical or horizontal movement confirms the advisories are advancing. Given the recurring front brake pad advisories, the pad thickness and disc condition should be physically measured rather than assumed serviceable, with particular attention to the nearside front which has worn on edge at 3mm previously, potentially indicating a sticking slider or caliper guide issue that accelerates inner-edge wear. The 2025 advisory regarding worn front tyres with edge wear is another targeted inspection point, as uneven shoulder wear on a Focus commonly points to suspension geometry drift, worn lower wishbone bushes, or bent rims from kerb contact. On the test route, the car should be driven over a smooth straight section at moderate speed and any steering pull or off-centre feeling noted, as this could indicate front geometry that has shifted since the last wheel alignment. The earlier ball joint play advisory on the nearside front suspension arm in 2021, combined with the more recent rear swivel pin advisories, suggests a vehicle whose rubber and pivot components are collectively approaching renewal age. Inspect the nearside front lower arm for any perished or split bush material, and check for dampness or cracking around the rear axle swivel pin housings. Finally, the TPMS fault recorded as a Major failure in 2022 should be confirmed resolved through a live read-out, as a persistently illuminated warning would render the vehicle non-compliant at its next test.
