2015 Mazda CX-5 2.2L Diesel · DA65 FVO

The most recent MOT inspection on 5 November 2025 resulted in a pass, but the vehicle's maintenance trend shows signs of recent deterioration rather than stability. The transition from a clean pass in 2024 to a dangerous failure in late 2025 is a significant red flag, specifically regarding the nearside rear brake pads which were recorded at less than 1.5mm thickness. While the vehicle has passed subsequent tests, the presence of recurring advisories regarding steering rack inner joints and anti-roll bar linkage ball joints suggests that certain suspension and steering components are entering a phase of progressive wear. The history also indicates intermittent issues with emissions and oil leaks in previous years, suggesting that while the vehicle is being kept roadworthy, it is currently subject to the typical mechanical degradation expected of an eleven-year-old vehicle. With 97,932 miles recorded over approximately eleven years, the vehicle has averaged roughly 8,900 miles per year. This represents typical, moderate usage for a diesel or petrol SUV of this age and suggests the vehicle has not been subjected to extreme high-speed motorway cruising nor has it suffered from the detrimental effects of excessive short-trip urban idling. However, this level of mileage means that major service items and wear-and-tear components are likely approaching the end of their functional lifespans. You should anticipate that components such as the timing chain or belt, water pump, and various rubber bushings are nearing a period where replacement may be necessary to maintain reliability. During your test drive, you must pay close attention to the steering and front-end stability. The advisory for play in the steering rack inner joints can manifest as a vague or disconnected feeling through the steering wheel, or a light knocking sensation when navigating uneven road surfaces. Similarly, the play in the offside front anti-roll bar linkage ball joint may cause audible clunks when driving over speed bumps or during sharp cornering. You should also inspect the offside front tyre closely; the advisory regarding inner edge wear is a classic symptom of incorrect camber angles or worn suspension bushes, which can lead to rapid, uneven tyre degradation if the underlying geometry issue is not rectified. Finally, the historical mention of an oil leak and excessive exhaust smoke warrants a thorough visual inspection of the engine bay and the underside of the vehicle. Look for fresh oil seepage around the sump or valve cover and check for any signs of heavy carbon buildup around the exhaust manifold. Given the age of the vehicle, even if the MOT is currently clear, you should verify the service history for evidence of regular fluid changes, as oil and brake fluid degradation is time-dependent regardless of mileage. Check the condition of all rubber hoses and belts for perishing or cracking, and ensure the battery shows no signs of terminal corrosion, as these are common age-related failure points for a Mazda of this vintage.
