2015 Mazda 6 2.2L Diesel · LX15 VTY

The vehicle remains roadworthy, but the maintenance history indicates a trend of developing corrosion-related component wear. While the most recent test in May 2025 at 138,785 miles passed, the tester identified corrosion on both rear suspension arms. This follows a 2024 failure where rear coil springs were flagged for corrosion. Although the car has passed its latest inspection, the recurring appearance of rust on the undercarriage components suggests that the vehicle is beginning to show structural degradation typical of its age. At 138,785 miles over eleven years, this Mazda 6 has averaged approximately 12,600 miles per year, which is above the national average for its age. The record shows consistent usage, with a 10,266-mile gap between the January 2024 and 2025 tests. This high level of mileage places significant stress on the drivetrain and suspension systems, which is evidenced by the 2022 failure where the nearside track rod end dust cover failed alongside brake discs were worn thin and tyres were reaching the legal limit. A buyer must conduct a thorough physical inspection of the chassis to assess the extent of the rust noted on the rear suspension arms and coil springs. Given the history of corroded components, it is vital to check for structural integrity in the mounting points and areas where the exhaust meets the body. The previous failure of the inner brake discs in 2022 indicates that the braking system may be neglected until a failure becomes imminent, so the current state of the pads and discs should be verified for pitting or excessive thinning.
