2017 Mazda 6 2.2L Diesel · LO66 XOZ

The vehicle is currently roadworthy but the maintenance history indicates a reactive approach to repairs rather than preventative care. The most recent test in January 2026 at 180,168 miles resulted in a failure due to a non-functional offside rear seat belt and a loose front undertray. While the vehicle passed upon immediate re-test, the presence of a child seat prevented a full inspection of the adult seat belt, leaving a potential oversight. The trend shows that faults are only addressed once they trigger an MOT failure, which may mask underlying mechanical neglect. At 180,168 miles over nine years, this Mazda 6 has significantly higher-than-average mileage, averaging approximately 20,000 miles per year. Between February 2024 and January 2026, the car covered 33,804 miles in just under two years. This high-intensity usage pattern places immense strain on the drivetrain, suspension components, and braking system. The failure in February 2024 due to a loose wheel fixing is particularly concerning, as it suggests that basic safety checks on wheel torque were neglected during high-mileage service intervals. A buyer must conduct a thorough physical inspection of the front suspension and underbody. The 2025 test flagged play in the offside front track rod end, and given the high mileage, other bushes, control arms, and coil springs are likely nearing the end of their functional life. The loose undertray noted in 2026 should be checked to ensure the mounting points are not sheared or suffering from structural corrosion. Additionally, the brake system should be inspected for excessive disc wear or binding calipers, as the high annual mileage accumulation often leads to accelerated wear on these components.
