2015 Mazda Cx-3 1.5L Diesel · CU65 RXT

The vehicle most recently passed its MOT on 27 August 2026, following a significant failure just eight days prior. While the latest result shows no defects, the overall maintenance trend appears reactive rather than proactive. The failure in August 2026 was severe, involving dangerous structural tyre bulges on both rear tyres and multiple advisories regarding worn front tyres and pitted brake discs. This suggests that while the vehicle is currently compliant, the owner has only addressed critical safety issues when prompted by a test failure. The history of recurring advisories, particularly regarding tyre wear and sub-frame corrosion, indicates a pattern of running components close to their legal or mechanical limits. With 114,596 miles recorded over approximately eleven years, the vehicle has averaged roughly 10,418 miles per year. This is considered typical usage for a petrol-driven crossover of this age and suggests the vehicle has been used regularly for commuting or general road use rather than suffering from long periods of inactivity. This consistent mileage profile is generally positive as it reduces the risk of moisture buildup in the exhaust and brake systems, but it does mean that high-wear items such as suspension bushes, shock absorbers, and drivetrain components are likely approaching the end of their service life. You should expect a vehicle at this mileage to require more frequent attention to consumables and rubber components. A primary area of concern for a prospective buyer is the documented history of tyre issues and brake wear. The recent failure for tyre bulges indicates structural separation, which can be caused by impact damage or age-related perishing. During your test drive, pay close attention to any vibration through the steering wheel or a rhythmic thumping noise from the rear, which could indicate internal tyre damage or uneven tread wear. Furthermore, the advisory regarding pitted and scored rear brake discs suggests that the braking system may be prone to surface corrosion or binding. Listen for any grinding noises during deceleration or a shudder through the brake pedal, which would indicate warped or unevenly worn discs. Finally, you must address the ongoing advisory regarding corrosion on the front sub-frame. While the DVSA noted it was not seriously weakened, corrosion is progressive. You should inspect the underside of the vehicle for significant scale or flaking metal, particularly around mounting points. Additionally, given the age and mileage, check the condition of the suspension system for any clunks or knocks when driving over uneven surfaces, as the bushings and coil springs are likely fatigued. Ensure that the service history is documented to confirm that fluids, such as engine oil, coolant, and brake fluid, have been changed at appropriate intervals, as calendar-based degradation is as important as mileage-based servicing for a vehicle of this vintage.
