2018 Mazda CX-5 2.2L Diesel · MU51 RAW

The 2018 Mazda CX-5 has demonstrated a consistently stable roadworthiness record over the past five MOT cycles, with no defects or advisories recorded in any of the tests conducted between June 2021 and July 2025. The most recent test on 14 July 2025, at 51,368 miles, confirms the vehicle remains compliant with current UK regulations, though the absence of any recorded issues means no specific wear patterns or recurring failures are documented. This suggests the vehicle has either undergone regular, diligent maintenance or has benefited from favourable driving conditions and storage practices. However, the lack of advisories or defects does not preclude the need for a thorough independent inspection, as some components—particularly those subject to gradual wear—may not have been tested comprehensively. The mileage progression indicates a steady usage pattern, averaging approximately 6,421 miles per year, which is typical for a vehicle of this age. There are no abrupt spikes or prolonged periods of inactivity that would suggest neglect or extended storage-related issues. The most notable gap between tests is between the 2023 and 2024 MOTs, where the vehicle accumulated 13,174 miles in just over a year, yet still passed without incident. This suggests the owner maintained the car well during this period, though it also implies higher-than-average annual mileage, which could accelerate wear on suspension components, brake systems, and drivetrain fluids. The consistency of the mileage readings—with no discrepancies between the recorded figures and the test dates—adds credibility to the history, though a pre-purchase inspection would verify whether fluids and consumables have been serviced accordingly. Given the clean MOT history, a buyer should prioritise an inspection of high-wear items that are not routinely tested under the MOT scheme. The suspension system, including coil springs, bushes, and shock absorbers, should be examined for uneven wear or damage, particularly given the vehicle’s mileage. Brake components—discs, pads, and calipers—should be checked for uneven thickness or signs of overheating, as binding calipers or warped discs are not flagged in the MOT but can compromise stopping performance. Structural integrity, especially around wheel arches, sills, and the subframe, should be assessed for corrosion, as this is often not visible from the exterior but can compromise safety. Finally, the exhaust system should be inspected for leaks or excessive rust, as catalytic converter failures or exhaust gas leaks are not always detected during a standard MOT. While the vehicle’s history is unblemished, these areas warrant close attention to ensure long-term reliability.
