2015 Mazda 6 2.2L Diesel · SM15 OCE

The vehicle is currently roadworthy, having passed its most recent test in April 2026 at 106,675 miles. The maintenance trend shows a period of stability following a mechanical failure in early 2023. While the car has cleared the last two inspections without any defects, the introduction of advisories for general light underside corrosion in the latest tests indicates the beginning of a wear process that requires monitoring to prevent future structural degradation. The mileage pattern is consistent with typical usage for a vehicle of this age, averaging approximately 9,700 miles per year. There is a notable increase in usage between April 2024 and April 2025, where the car covered over 10,000 miles in twelve months. Since the 2025 test, the mileage has remained steady, adding roughly 9,000 miles in the final year. This regular interval suggests the vehicle is used consistently rather than sitting stationary for long periods, which generally benefits component health. A buyer should focus their physical inspection on the front suspension and braking system due to the faults recorded in the history. The April 2023 failure highlighted a fractured offside front anti-roll bar linkage and a binding brake caliper alongside pitted discs and a corroded brake pipe. Although these were rectified, the buyer should check for signs of play in rubber boots and ensure the brake lines are free of further corrosion. Additionally, the recurring advisories for light underside corrosion in 2025 and 2026 necessitate a close look at the sills and rear mounting points to ensure that surface rust is not progressing into structural decay.
