2009 Hyundai I30 1.6L Petrol · EA59 XUU

This 2009 Hyundai i30 has a concerning history of progressive corrosion that suggests the vehicle's structural condition is worsening. While the most recent MOT in November 2025 was a pass, it followed a failure involving lighting and tyre wear, and it highlighted ongoing issues with rear suspension arm corrosion. The primary risk pattern is a clear escalation of rust and degradation in the underside. In 2023, the records showed corrosion on fuel pipes, the fuel tank, coil springs, and anti-roll bars. By 2024, the corrosion had spread to the rear subframe mounting areas and inner subframe pins/bushes. The persistence of corroded suspension arms across multiple years indicates that while these parts are currently "not seriously weakened," the underlying issue of metal decay is not being addressed and is spreading to more critical structural components. The mileage of approximately 100,677 miles is relatively low for a 17-year-old vehicle, averaging under 6,000 miles per year. While this suggests less mechanical wear on the engine and drivetrain, low annual mileage often correlates with longer periods of standing. This can be detrimental to a car's underside, as moisture sits on components and accelerates the type of heavy corrosion seen in this MOT history. The trend is clearly worsening rather than stable.
