2015 Ford Focus 1.5L Diesel · B2 JGE

A recurring theme of corrosion across the rear sub‑frame and rear suspension arms defines the mechanical narrative of this 2015 Focus, with advisories appearing in every MOT since 2022 and a further note on the front brake discs each year. The car failed a test on 19 February 2026 because the engine MIL indicator was inoperative, but it passed the following day, indicating that the fault was either cleared or deemed non‑critical for roadworthiness. The pattern shows a stable, albeit persistent, rust issue that has not progressed to a point of structural weakness, while the brake disc wear remains within acceptable limits but is repeatedly flagged. At 51,184 mi the vehicle averages roughly 4,650 mi per year, well below the typical UK usage for an eleven‑year‑old car. Such low mileage can imply periods of limited use or storage, which may have contributed to the observed corrosion on chassis components that are exposed to moisture when stationary. The modest annual accumulation reduces the expected wear on consumables such as tyres, brakes and suspension bushings, yet it does not mitigate the gradual rusting noted in the MOT records; the mileage alone does not guarantee the integrity of the affected parts. Prospective buyers should give particular attention to the rear sub‑frame and lower suspension arms on both sides. A hands‑on inspection should look for any surface rust that appears to be penetrating, signs of paint blistering, or loosened mounting bolts. During a test drive, listen for creaking or clunking noises when traversing bumps or cornering, and feel for any steering pull or uneven tyre wear that could indicate compromised mounting points. The front brake discs, repeatedly noted as worn or pitted, should be measured for thickness and examined for deep scoring; a firm, consistent pedal without pulsation is essential, and any vibration under braking warrants immediate replacement. The engine MIL fault recorded in February 2026 must be diagnosed with a scan tool to confirm that the underlying issue has been resolved and that no pending emissions codes remain, as a lingering fault could affect future MOTs and fuel efficiency. Although the windscreen washer deficiency from 2021 has not recurred, verifying that the washer system now delivers adequate fluid is prudent. Finally, the rear tyres were flagged for slight damage or cracking; inspect the tread for dry rot, sidewall cracks, and ensure the tyres are still within their service life, replacing them if any deterioration is evident.
