2009 Mazda 6 1.8L Petrol · CA59 BCX

The vehicle's roadworthiness shows a concerning downward trend in structural and mechanical integrity. While the November 2025 test at 139,900 miles resulted in a pass, the record shows a pattern of recurring advisories and previous failures that suggest underlying issues. The most recent test flagged a binding nearside rear service brake and persistent corrosion on the rear sub-frame and both rear suspension arms. Although the tester noted the corrosion was not seriously weakened, these issues have been present in the records since at least November 2024, indicating that the oxidation is a long-term, unaddressed condition. The mileage accumulation appears consistent with the vehicle's age, averaging approximately 8,200 miles per year. The data shows steady progression from 75,334 miles in 2017 to the current 139,900 miles. There are no significant gaps in the testing frequency, suggesting the vehicle has been in regular use. However, the consistency in mileage does not correlate with a consistent maintenance standard, as the vehicle has frequently failed tests due to neglected consumables and mechanical components. A prospective buyer must prioritise a thorough inspection of the underbody. The recurring mentions of rear sub-frame corrosion, suspension arm corrosion, and exhaust system decay since late 2024 suggest that the vehicle is susceptible to significant structural degradation. The presence of headlamp lens clouding in the 2025 test also indicates age-related wear that may affect night-time visibility. Mechanical attention should also be directed toward the braking system and suspension. The history shows a repetitive struggle with brake efficiency, including a failure in September 2021 for low parking brake efficiency and a binding nearside rear brake in November 2025. Previous failures regarding worn brake discs, thin pads, and imbalanced braking suggest that while some repairs have been made, the braking system requires close monitoring. Additionally, the history of worn tyres and failing wiper systems suggests a tendency for the previous owners to delay basic maintenance until a failure occurs.
