2010 Mazda 3 1.6L Petrol · FX10 YMA

The vehicle is currently roadworthy, but the maintenance record shows a worsening trend regarding structural integrity. While the most recent test in February 2026 at 115,318 miles passed, the tester identified persistent corrosion on the rear sub-frame and both rear lower suspension arms. This mirrors the exact advisories from the January 2025 test, indicating that while the oxidation has not yet reached a point of failure, it is progressing unchecked. At 16 years old with 115,318 miles, the Mazda 3 has averaged approximately 7,200 miles per year, which aligns with typical annual usage for a vehicle of this age. The mileage accumulation is consistent, with roughly 3,500 miles driven between the 2023 and 2024 tests, and another over 3,000 miles between February 2024 and January 2025. This regular use suggests the car has not sat stationary for long periods, though the consistent exposure to the elements likely contributes to the ongoing rust seen on the lower chassis. A buyer must perform a thorough physical inspection of the rear sub-frame and suspension mounting points to determine the depth of the corrosion. The tester has flagged these areas repeatedly over the last year, and the transition from an advisory to a structural failure is a significant risk for older Mazdas. The 2025 failure due to a worn offside front lower ball joint and a failed stop lamp indicates that mechanical components are reaching the end of their service life. Attention should be paid to any scaling or thinning metal on the suspension arms, which would eventually necessitate expensive structural repairs.
