2016 Mazda CX-5 2.2L Diesel · NG66 UFW

Structural integrity and suspension health represent the primary mechanical concerns for this Mazda CX-5, as evidenced by a 2024 failure involving a fractured offside rear coil spring. While the vehicle successfully passed its most recent MOT on 17 November 2025 with no recorded defects, the historical trend shows intermittent issues rather than a perfectly clean record. The failure in 2024, coupled with a concurrent advisory for uneven tyre wear on the offside front, suggests that the suspension geometry or component fatigue requires closer scrutiny than a standard pass might imply. Accumulating 89,081 miles over a ten-year period results in an average of approximately 8,900 miles per annum, which aligns with standard usage expectations for a vehicle of this type. There are no significant gaps in the testing history that would suggest extended periods of dormancy, meaning the mechanical systems have been subjected to regular, consistent operation. This mileage level places the vehicle in a phase where secondary suspension components, such as dampers and bushes, are likely reaching the end of their design life, regardless of the absence of recent failure items. During your test drive, pay particular attention to the rear suspension by listening for metallic clunks or rattles when traversing uneven surfaces, as coil spring fractures can sometimes lead to secondary damage to the shock absorbers or mounting points. The previous advisory regarding uneven tyre wear on the offside front is a critical indicator of potential tracking misalignment or worn steering linkages. You should verify this by ensuring the vehicle tracks straight on a flat road without pulling to either side and by checking for any vibration through the steering wheel at motorway speeds, which could indicate that the underlying cause of the uneven wear has not been fully rectified. Beyond the suspension and steering, ensure the windscreen washer system functions correctly, as this was a specific failure point in 2021. While the system passed its most recent inspection, the pump and nozzles are prone to blockage or electrical failure over time. Furthermore, because the vehicle has reached this mileage milestone, perform a thorough visual inspection of the underside for any signs of corrosion on the subframe or brake lines, and listen for any unusual grinding or binding noises from the brakes during low-speed stops, which would indicate that the calipers or pads are nearing the end of their service interval.
