2010 Toyota Yaris 1.3L Petrol · DE10 RHO

Persistent corrosion of the brake lines stands as the primary mechanical concern for this Toyota Yaris, with the issue appearing consistently across multiple annual inspections. While the vehicle successfully passed its most recent MOT on 6 January 2026, the record shows a recurring pattern where brake pipes are noted as corroded and masked by grease or other materials, suggesting that the underlying degradation has not been permanently rectified. The 2026 test also included a failure due to an exhaust gas leak and an emissions fault, indicating that the vehicle has required recent intervention to meet current roadworthiness standards, moving beyond the minor structural advisories noted in previous years. At 72,780 miles over sixteen years, the vehicle has seen an average usage of approximately 4,500 miles per annum. This low-mileage profile is consistent across the documented MOT history, which shows regular annual testing without significant gaps in service. While this suggests the vehicle has not been subjected to high-intensity motorway use, the long-term presence of corrosion on the brake lines and suspension components indicates that the car may have been stored in conditions that promote oxidation, or that it has seen extended periods of infrequent use, which can accelerate the deterioration of metallic components exposed to the elements. Prospective buyers should prioritise a thorough physical inspection of the brake lines, specifically looking for any signs of flaking rust or dampness beneath the grease coating mentioned in the test history. During a test drive, pay close attention to the feel of the brake pedal; any sponginess or excessive travel could indicate a compromise in the hydraulic system. It is advisable to have a mechanic remove the protective grease or tape from the brake lines to assess the true extent of the metal thinning, as the MOT advisories confirm that these components have been a long-standing point of concern. The structural integrity of the subframe and the front lower suspension arms also warrants close scrutiny, as these areas were flagged for corrosion in 2021 and 2022. While these were not deemed to be seriously weakened at the time, rust can progress over time, particularly in hidden cavities. Listen carefully for any metallic knocking or clunking sounds when driving over uneven surfaces or speed bumps, which could signify play in the suspension bushes or ball joints. Given the recent exhaust and emissions failure, ensure the engine idles smoothly and that there is no audible blowing from the exhaust system when the vehicle is at operating temperature.
