2009 Honda Civic 1.8L Petrol · FN59 GAX

The vehicle is currently roadworthy but the maintenance history reveals a worsening trend regarding structural integrity. While it passed its most recent test in December 2025 at 89,072 miles, the tester flagged significant corrosion on the sills, underbody, and rear axle. This follows a recurring pattern identified in 2024 where the front subframe and mounting areas were also noted for corrosion. Although the vehicle has passed tests, the progression of rust across multiple components suggests that the protective layers are deteriorating despite previous sealing efforts. At 17 years old, the recorded mileage of 89,072 miles is remarkably low, averaging approximately 5,240 miles per year. This low usage pattern often correlates with the accelerated corrosion observed here, as vehicles that sit for long periods are more susceptible to moisture retention and surface oxidation. There is a notable gap in activity between September 2022 and November 2023, where the car covered only 150 miles in over fourteen months, which supports the theory that the mechanical issues are likely due to age-related decay rather than wear-related failure. A buyer must conduct a thorough physical inspection of the underbody, focusing specifically on the sills and the rear subframe to ensure the corrosion has not progressed to structural weakness. The 2024 failure highlighted critical issues with rear brake discs, pads, and corroded calipers, indicating that the braking system has been neglected. Pay close attention to the rear coil springs and shock absorber bushes, as these have been flagged as corroded across multiple tests. Given the history of perished tyres and uneven front wear, the condition of all rubber components should be be checked for dry rot and cracking.
