2018 Mazda Cx-3 1.5L Diesel · GM18 APF

The most recent MOT, carried out on 12 February 2026, resulted in a failure due to a dangerous condition on the off‑side front tyre, where the ply or cords are exposed and the tread is separating. An advisory also highlighted that the front brake linings are approaching the minimum thickness. Compared with the preceding three years, the vehicle’s defect profile is clearly deteriorating: in 2025 the car passed with no recorded faults, in 2024 it showed rear tyre wear close to the legal limit and a light oil mist from a rear shock absorber, and in 2023 both front and rear brake pads were already flagged as thin. The progression from advisory‑only items to a dangerous tyre fault indicates a worsening maintenance trend that the current owner has not fully addressed. At 94,284 miles recorded in early 2026, the Mazda CX‑3 has accumulated roughly 11,800 miles per annum over its eight‑year life, which sits squarely within the typical usage envelope for a compact crossover of this age. There are no obvious mileage gaps that would suggest prolonged periods of inactivity, so the wear observed on the brakes, tyres and suspension is consistent with normal calendar and distance‑related degradation rather than abrupt over‑use. The mileage level also means that consumables such as brake discs, suspension bushes and engine mounts are likely approaching the latter stages of their service life and should be inspected closely. A prospective buyer should treat the front tyre as an immediate safety priority; the exposed cords mean the tyre is structurally compromised and must be replaced before any further road use. While the vehicle is being examined, verify that the replacement tyre matches the original size and load rating, and check the remaining three tyres for uneven wear patterns, sidewall cracking or tread depth below 1.6 mm, which could indicate alignment or suspension issues. The front brake linings are already at the minimum legal thickness, so a full brake service is advisable – replace the pads on both front wheels, inspect the rotors for scoring or glazing, and listen for any squeal or pulsation under braking during a test drive. The rear shock absorber that was noted to have a light oil mist may be beginning to lose its damping efficiency; look for excessive body roll, clunking over bumps or uneven tyre wear, and consider a pressure test or replacement if any leakage is confirmed. Beyond the immediate safety items, the buyer should conduct a comprehensive age‑related inspection. Check the 12‑volt battery for terminal corrosion and verify its cranking voltage, as eight‑year‑old batteries often suffer from sulfation even with moderate mileage. Examine all fluid levels – engine oil, coolant, brake fluid and power‑steering fluid – and confirm whether the last change dates align with the manufacturer’s service intervals; fluids can deteriorate with time regardless of mileage. Inspect the suspension bushings, ball joints and control arms for any signs of cracking, excessive play or corrosion, especially around the wheel arches where standing water may have accumulated. Finally, review the service book for evidence of regular oil changes, timing‑belt or chain service, and any recorded replacement of wear items; a well‑documented history will give confidence that the vehicle’s mechanical health can be restored to a reliable state.
