2016 Mazda CX-5 2.2L Diesel · DU65 PBF

Corrosion and progressive wear in the suspension and braking systems represent the primary mechanical risks for this vehicle, as evidenced by the December 2025 MOT pass which carried multiple advisories regarding structural and component degradation. The recent history shows a trend of worsening mechanical advisories, moving from simple tyre and brake pad wear in earlier years to more significant concerns regarding the rear sub-frame and lower suspension arms. The presence of corrosion on the rear sub-frame and both rear lower suspension arms, alongside play in the front lower suspension arm ball joints, indicates that the chassis and steering components are entering a phase of active deterioration that will require monitoring. The vehicle has covered 97,127 miles over its ten-year lifespan, averaging approximately 9,713 miles per year. This usage pattern is consistent with typical annual accumulation for a vehicle of this age. Mechanically, this level of mileage suggests that wear on consumables such as brake discs, tyres, and suspension bushes is expected, and the MOT record confirms this through repeated advisories for worn tyres and pitted brake discs. The steady mileage accumulation suggests the vehicle has been in regular use rather than sitting stationary for extended periods, which aligns with the observed wear on various mechanical interfaces. A physical inspection and test drive should focus heavily on the reported suspension and chassis issues. Given the advisories for corrosion on the rear sub-frame and lower suspension arms, as well as play in the front ball joints, listen for any rhythmic knocking, clunking, or creaking sounds when driving over uneven surfaces or speed bumps. Any wandering sensation in the steering or a tendency for the vehicle to pull to one side during straight-line driving could indicate that the reported play in the front ball joints is progressing. Furthermore, the pitted and scored state of both the front and rear brake discs should be assessed for any signs of pedal judder or vibration during braking, which could indicate uneven surface wear or warping. The braking system history is particularly notable, having recorded a dangerous failure in February 2025 due to brake pads being below the legal limit, alongside a fractured offside rear coil spring. While the vehicle passed its subsequent December 2025 test, the recurring advisories for worn brake discs and thin pads suggest the braking components are nearing the end of their service life. During a test drive, pay close attention to the responsiveness of the brake pedal and ensure there is no excessive travel or sponginess. Additionally, since an engine malfunction light was flagged in early 2025, verify that no warning lights remain illuminated on the dashboard and that the engine performs smoothly without hesitation or irregular idling.
