2018 Mazda CX-5 2.2L Diesel · E22 DSW

The latest DVSA MOT test on 2026-08-03 resulted in a passing outcome, but the vehicle’s overall maintenance history reveals a concerning pattern of critical failures. The most significant issue occurred during the 2025-07-25 MOT, where the front brake system was deemed dangerous due to brake pads being reduced to less than 1.5 mm in thickness and the front discs showing severe and obvious wear. This failure was not rectified before the subsequent MOT in 2026, suggesting either incomplete repairs or ongoing neglect, as no further defects were recorded in the intervening period. The presence of an advisory for nearside rear tyre wear close to the legal limit—particularly on the edge—indicates either aggressive driving habits or excessive cornering forces, which could exacerbate tyre degradation over time. While the intervening MOTs in 2024 and 2023 were clean, the recurring failure in 2025 underscores a systemic issue with brake maintenance, warranting immediate attention before the vehicle is put into service. The recorded mileage of 58,671 miles for a 2018 Mazda CX-5 represents a moderate annual usage rate of approximately 7,334 miles per year, which is consistent with typical driving patterns for its age. This level of mileage is neither exceptionally low nor high, but it does not preclude wear-related concerns, particularly on high-wear systems such as brakes, suspension, and tyres. The absence of significant mileage gaps suggests the vehicle has been in regular use, which may have contributed to the observed brake wear. However, the 2025 failure highlights that even at this mileage, consumables like brake pads and discs can degrade rapidly if not serviced promptly. Additional wear could be expected on suspension components, such as bushes and springs, which may exhibit clunking or uneven ride quality if neglected, and the tyres may show signs of uneven wear patterns or sidewall damage from prolonged exposure to road conditions. Given the vehicle’s MOT history, the most critical immediate inspection should focus on the front brake system. The previous failure indicates that the brake pads and discs were worn to dangerous levels, and the vehicle should not be driven until these components are fully serviced. Upon inspection, check for any signs of brake fluid contamination, warping of the discs, or binding calipers that could exacerbate wear. During a test drive, listen for unusual grinding noises from the front brakes, which may indicate metal-to-metal contact between the pads and discs, and monitor for a reduced braking response or pulsation in the pedal, which could signal warped discs or warped brake rotors. Additionally, verify that the brake pads are now fully regripped to at least 1.5 mm thickness, and consider replacing the discs if they show significant warping or scoring. If the brake system has been repaired, ensure the MOT records confirm compliance with the DVSA’s standards before proceeding. Beyond the brakes, the nearside rear tyre advisory suggests the tyres should be closely inspected for sidewall damage or excessive edge wear, which could compromise handling and safety. Check the tyre pressure and tread depth, ensuring they meet the legal minimum of 1.6 mm across three-quarters of the tread, and look for signs of uneven wear or cracks in the sidewall, which may indicate underlying suspension or alignment issues. Given the vehicle’s age and mileage, the suspension components—particularly the coil springs, shock absorbers, and suspension bushes—should be examined for signs of wear or damage. Listen for clunking noises when driving over bumps, which may indicate failing suspension bushes or worn springs, and check for uneven tyre wear that could signal misalignment or binding in the steering system. For the tyres, consider rotating them to ensure even wear, and if the mileage is high, replace them sooner rather than later to avoid premature failure. Lastly, address the potential brake system failure promptly to prevent further deterioration and ensure roadworthiness.
