2009 Toyota Yaris 1.3L Petrol · CY59 AEJ

The vehicle is currently roadworthy but shows a clear trend of worsening structural degradation related to corrosion. While it passed its latest MOT on 17 June 2026 at 75,740 miles, it had failed just eight days prior for an inoperative registration plate lamp. More concerning are the recurring reports of corrosion across the lower fuel pipes, front sub-frame, rear axle, and rear inner vehicle structure. Although the tester noted that structural rigidity is not yet significantly reduced, the presence of rust in multiple critical areas indicates an active oxidation process that is accelerating. At 17 years old, the 75,740 recorded miles represent an exceptionally low average, of approximately 4,455 miles per year. The usage pattern appears consistent, with 11,504 miles driven between the 2023 and early 2024 tests, and another 19,726 miles covered between September 2024 and June 2026. However, low mileage often correlates with longer periods of stationary time that accelerate degradation of rubber components and metal surfaces, which aligns with the corrosion issues identified in the recent inspections. A buyer must conduct a thorough physical inspection of the underside to assess the depth of the rust on the front sub-frame and rear axle. Particular attention should be paid to the sills and rear inner structure to ensure the corrosion remains merely superficial. The 2023 advisory regarding uneven tyre wear also warrants an inspection of the suspension bushes and alignment to ensure no mechanical failures have developed. Given the flagged fuel pipes, the fuel lines should be checked for leaks or thinning walls, as these represent a significant fire risk if the corrosion continues to progress.
