2018 Mazda CX-5 2.2L Diesel · M66 GTL

The latest MOT test on the 2018 Mazda CX-5 recorded a passing result on 2026-05-20, but this follows a pattern of inconsistent maintenance history that suggests the vehicle has encountered significant issues requiring attention. The most critical failure occurred in 2024-08, where the MOT was failed due to multiple advisories, including front brake disc wear close to legal limits, rear tyre conditions nearing perishing, and near-edge wear on the nearside front tyre. While the 2025 tests were clean, the 2024 failure and the persistent presence of advisories—particularly the repeated rear tyre cracking and front brake disc wear—indicate a trend of deferred maintenance rather than a stable or improving condition. The engine MIL failure in 2025-05 also highlights underlying electrical or sensor issues that may have been overlooked or not rectified promptly, warranting further investigation before purchase. The recorded mileage of 73,509 miles for a vehicle aged eight years represents a moderate annual usage rate of approximately 9,189 miles per year, which is typical for its age and class. However, the mileage data alone does not fully explain the maintenance inconsistencies, as lower mileage could imply prolonged periods of inactivity, which can exacerbate issues such as standing corrosion, fluid degradation, or tyre perishing. Conversely, higher mileage might suggest more aggressive use, accelerating wear on suspension components, brakes, and tyres. The absence of recent high-mileage spikes does not absolve the need for thorough inspection, especially given the recurring tyre and brake advisories, which may reflect underlying wear patterns exacerbated by either infrequent servicing or prolonged static conditions. To proceed with a purchase, the prospective buyer should conduct a meticulous physical inspection focusing on the tyre conditions, as the repeated MOT advisories regarding cracking and perishing indicate that the tyres may be approaching or already nearing unsafe limits. The front brake discs show significant wear close to the legal minimum, suggesting that the braking system has been under stress, potentially due to prolonged driving at higher speeds or uneven tyre wear. On a test drive, listen for uneven brake pedal feel, shuddering during braking, or signs of brake dust accumulation on the tyres, which could indicate warping or binding calipers. Inspect the front brake discs for scoring, pitting, or glazing, and check for any fluid leaks around the brake master cylinder or caliper mounts, as this may signal failing seals or hydraulic system issues. Beyond the immediate concerns, the buyer should verify the suspension components, particularly the rear shock absorbers, which exhibited light misting of oil in the latest MOT. This condition, while not failing the test, is a clear indicator of internal failure and should be addressed soon, as misted shocks can lead to poor ride quality, uneven tyre wear, and compromised handling stability. Test the vehicle for excessive body roll, clunking noises from the rear suspension during cornering, or uneven tyre wear patterns that could suggest misaligned shocks or worn suspension bushes. Additionally, check the exhaust emissions system for leaks or unusual noises, as the engine MIL failure may point to a broader electrical or sensor issue that could affect performance and emissions compliance. Finally, given the vehicle’s age and usage profile, inspect the tyre sidewalls for signs of perishing or cracking, which can compromise structural integrity, and verify that the service history includes mandatory fluid changes, such as the brake fluid, coolant, and transmission fluid, which degrade over time regardless of mileage.
