2009 Mazda 6 1.8L Petrol · SJ59 XPD

The vehicle remains roadworthy but the mechanical history shows a worsening trend regarding structural integrity. While it passed its most recent test in November 2022 at 70,992 miles, the tester identified multiple points of significant corrosion that were not present in earlier inspections. The progression from a clean record in 2019 to widespread corrosion on the subframes, suspension arms, and vehicle structure by 2022 indicates that environmental oxidation is accelerating despite the relatively low annual usage. The mileage profile is notably low for a seventeen-year-old vehicle, averaging approximately 4,176 miles per year. The data shows consistent but minimal use, with only 21,738 miles covered between the November 2018 and November 2022. However, this low mileage often correlates with the structural issues seen here, as vehicles that sit stationary are prone to accelerated rust. The presence of pitting and scoring on brake discs in the 2022 test suggests the brakes have not been used frequently enough to prevent surface oxidation on the metal surfaces. A prospective buyer must conduct a thorough physical inspection of the subframes and suspension mounting points to determine if the corrosion noted in 2022 has progressed toward structural thinning. The tester specifically flagged the front subframe and rear suspension mounting areas as corroded, which are critical components for vehicle handling and safety. Attention should also be paid to the exhaust system and the brake discs, as the 2022 record highlights deterioration and fluctuating performance that are likely nearing replacement intervals to ensure reliable stopping performance.
