2007 Ford Focus 1.6L Petrol · KB07 EOG

Chronic rear axle corrosion is the defining mechanical theme of this Ford Focus, with coil spring and subframe advisories appearing across multiple test cycles and representing a progressive rather than transient issue. The most recent test on 6 April 2023 recorded a pass, but it carried five advisories all clustered around the rear suspension and subframe assembly, indicating surface corrosion that had been developing for at least two years prior. Earlier tests reinforce this pattern: both rear coil springs were first flagged as corroded in April 2021, and front lower arm rear bushes were noted as worn in January 2019, suggesting a longer standing issue with suspension component degradation. Two failures are also recorded within the available history. The April 2023 failure was caused by an inoperative offside headlamp on dipped beam, while the April 2021 failure cited a non-functioning nearside headlamp main beam and an insufficient front windscreen washer supply. These lighting and washer failures are relatively straightforward electrical and fluid items, but they confirm the vehicle has not maintained a fully clean record across the recorded testing period. The mileage profile for this 2007 vehicle stands at 49,347 miles, equating to an annual accumulation of roughly 2,600 miles over its nineteen year life, which is notably low for the age. This restrained usage reduces wear on high mileage items such as the clutch, brake friction material and internal engine components, but extended periods of light or stationary use can accelerate corrosion on exposed underbody components, particularly the rear springs, subframe and suspension arms that have been flagged in the advisories. There are no multi-year gaps in the MOT record, with tests documented in 2019, 2020, 2021, 2022 and 2023, suggesting the vehicle has remained in regular use and on the road rather than laid up for prolonged periods. The relatively stable mileage progression between tests is consistent with the low annual rate rather than any sudden long-distance use. For a prospective buyer, the rear suspension and subframe condition warrants close physical inspection beneath the vehicle, as the 2023 advisories specifically noted that corrosion had not yet seriously weakened the components but progression is a clear risk on a vehicle of this age and exposed underbody location. A thorough examination should look for any flaking, bubbling or perforation of the rear subframe metal, paying particular attention to mounting points and welds, as well as surface pitting or cracking on the visible sections of the rear coil springs where they seat into the spring pans. The front lower arm rear bushes flagged in 2019 should also be checked for renewed wear, which can manifest as a knock or clonking noise from the front suspension over speed humps or uneven road surfaces, vague steering response, or uneven front tyre wear across the inside or outside shoulder. On a test drive, listen for any rear suspension noise over bumps, particularly clunks or rattles that might indicate loose or corroded spring seats, and feel for any instability or wandering behaviour at speed that could point to compromised rear arm bushings. Beyond the suspension, the headlamp and washer failures recorded in 2021 and 2023 should prompt verification that all exterior lighting functions correctly, including main beam, dipped beam, indicators and rear lights, and that the washer system delivers adequate fluid to both the front and rear screens as applicable. Inspect all four tyres for age-related cracking in the sidewalls, as a nineteen year old vehicle may have replacement tyres of indeterminate age even if the tread depth is satisfactory, and check that front and rear brake components show even wear given the low mileage accumulation. The exhaust system, brake pipes and fuel lines should be examined for corrosion given the underbody rust pattern already established at the rear, and a check for any oil leaks or coolant residue from the engine and gearbox would be prudent on a test drive. Overall the recorded history presents a vehicle that has remained roadworthy at each test but carries a recurring and worsening pattern of rear underbody corrosion that demands hands-on assessment before purchase.
