2005 Hyundai Accent 1.6L Petrol · HN55 CPU

This 2005 Hyundai Accent has consistently passed its MOTs in recent years, but with a single and persistent theme. The most recent result in September 2025 was a pass, but it followed a failure just two days earlier for a dangerous offside front tyre with exposed ply or cords, which was clearly rectified. However, the recurring note of a corroded exhaust system appears in every single MOT test since at least 2022, and it was significant enough to be a reason for the 2025 failure alongside the tyre. The pattern shows a stable, long-term corrosion issue rather than a sudden deterioration. The fact that it's been noted as an advisory for several years and finally caused a failure in 2025 suggests the corrosion is now severe enough to meet the threshold for failure. This indicates the exhaust condition is likely worsening gradually and will almost certainly require replacement in the near future, if not already. The tyre issue in 2024 and 2025 also points to a pattern of tyre neglect or possibly alignment and suspension wear affecting that specific wheel. With only 52,134 miles over 21 years, the very low annual average of roughly 2,500 miles is significant. This could mean the car was used sparingly, perhaps as a second car, or spent long periods off the road. Such low mileage does not mean low wear; in fact, prolonged inactivity can cause perishing of rubber components like tyres, hoses, and bushings, and may lead to corrosion in areas that would normally stay dry and warm with regular use.
