2013 Mazda 6 2.2L Diesel · SN13 XMF

The vehicle remains roadworthy but the maintenance history reveals a clear worsening trend regarding structural and component degradation. While it passed the most recent test in September 2025 at 134,915 miles, the tester identified significant corrosion on the subframe, the nearside front suspension arm, and the rear integral body structure. Although these areas were not yet classified as seriously weakened, the presence of rust across multiple structural points indicates that the vehicle is entering an advanced stage of environmental decay. The mileage pattern is consistent with a 13-year-old vehicle, averaging approximately 10,400 miles per year. Between the September 2022 test at 120,376 miles and the October 2024 test at 131,762 miles, the car covered 11,386 miles, showing steady annual usage. The interval between the October 2024 and September 2025 tests shows another 3,153 miles, which aligns with the established usage profile rather than any rapid accumulation. A buyer must conduct a thorough underbody inspection to assess the depth of the corrosion noted on the subframe and rear integral body structure. The recurring issues with suspension components, specifically the ball joints and bushes flagged in both 2023 and 2024, suggest that the front end is requiring frequent replacement intervals. Furthermore, the 2024 report of corroded brake pipes across all four corners indicates a high risk of future hydraulic failure if these lines have not been replaced or treated, as the grease mentioned in the record likely masked the extent of the oxidation.
