2015 Mazda 6 2.2L Diesel · WM15 WDF

Recurring issues with coil spring integrity represent the primary mechanical concern for this vehicle, evidenced by two separate major failures for fractured springs in 2023 and 2025. While the most recent test on 13 July 2026 resulted in a pass with no recorded defects, the history shows a pattern of suspension component failure that has required intervention. This follows a period of tyre-related advisories and brake disc wear noted in previous years, though the recent two years of testing show a shift away from consumable wear towards specific structural component failures. The vehicle has covered 67,362 miles over its 11-year lifespan, averaging approximately 6,124 miles per year. This mileage profile is consistent with typical annual accumulation for a vehicle of this age, suggesting a regular but relatively light usage pattern rather than long periods of stationary storage. Mechanically, this level of usage means that while major drivetrain components may have lower total wear than a high-mileage equivalent, components subject to environmental degradation and fatigue, such as suspension springs and rubber seals, are still subject to age-related deterioration. Prospective buyers should pay close attention to the suspension system during a test drive to ensure the previous coil spring failures have been fully addressed and that no further issues exist. Listen for any metallic clunking or knocking sounds when driving over speed bumps or uneven road surfaces, which could indicate failing suspension bushes or remaining issues with the coil springs. Additionally, because the 2021 record flagged a nearside rear brake disc as pitted and scored, it is advisable to check for any pedal judder or vibration under braking, which can indicate uneven disc wear or binding calipers. Tyre condition also warrants a physical inspection, given the history of edge wear and damage noted in 2022 and 2023. Check the current tread depth and look specifically for uneven wear on the inner or outer edges of the 19-inch tyres, as this can indicate alignment issues or worn suspension geometry. Ensure there is no visible cracking or perishing on the sidewalls, particularly on the rear tyres, to confirm that the previous advisories regarding tyre degradation have been rectified with fresh rubber.
