2016 Mazda Cx-3 1.5L Diesel · YN66 NLO

The most recent MOT test on this Mazda CX-3 took place on 2026-07-17 and resulted in a passing grade, though it was accompanied by several persistent advisories that suggest ongoing or recurring issues requiring attention. The vehicle’s MOT history reveals a pattern of recurring defects rather than a clear improvement or stability in maintenance, with the most critical failures—such as the nearside rear coil spring fracture in 2025 and the dangerous offside front tyre condition in 2022—indicating that while the car has passed its tests, underlying mechanical wear is not yet at a catastrophic stage. The oil leak and brake pipe corrosion advisories are particularly concerning, as they may signal broader issues with the engine bay sealing, drivetrain lubrication, or brake system integrity, which could escalate if left unaddressed. The nearside front tyre damage and edge wear further imply that the vehicle has undergone significant lateral stress, potentially from poor alignment, suspension misalignment, or aggressive cornering. The recorded mileage of 92,599 miles for a vehicle aged around ten years represents a moderate annual usage rate of approximately 9,260 miles per year, which is typical for its age and class. However, the absence of a service history or any clear indication of long periods of inactivity suggests that the car has been driven regularly, which accelerates wear on consumables like tyres, brakes, and suspension components. The rapid progression of tyre wear—from 1.6mm below legal limits in 2022 to near-legal limits in 2023 and 2025—points to either aggressive driving habits or a poorly maintained suspension setup, both of which can lead to uneven tyre degradation and premature tread failure. Additionally, the lack of a service record or mileage gaps makes it difficult to ascertain whether the vehicle has been subjected to routine maintenance, which is critical for components like the coil spring, brake system, and fluid systems, all of which have shown signs of wear or failure. For a prospective buyer, this Mazda CX-3 warrants a thorough mechanical inspection to address the identified advisories and potential underlying issues. First, the oil leak should be investigated immediately, as persistent oil loss can lead to engine damage, particularly if it is originating from the valve cover gasket or oil seal areas. Listen for any unusual engine noises or check for oil contamination in the brake fluid reservoir, as oil mixing with brake fluid can cause brake failure. The corroded brake pipes, especially the offside front pipe, are a critical concern; inspect the entire brake system for corrosion, particularly around the hoses and calipers, and check for binding or excessive play in the brake actuators. A test drive should reveal any clunking noises from the suspension, particularly when cornering or over bumps, which may indicate worn suspension bushes or coil spring failure. The nearside rear coil spring fracture from 2025 is a major red flag; visually inspect the remaining springs and subframe for signs of further deterioration, and check for uneven ride height or excessive bounce on the rear axle. In addition to the mechanical checks, the tyres must be thoroughly examined. The inner edge wear and cuts on the front tyres suggest that the vehicle has been subjected to lateral forces, which could stem from misaligned wheels, incorrect tyre pressures, or poor alignment. Measure the remaining tread depth on all tyres and ensure they are evenly worn; replace any tyres that are close to the legal minimum or showing severe edge wear. The nearside front tyre damage indicates that the vehicle may have been involved in a minor incident or driven through rough conditions, so check for any structural damage to the wheel arches or suspension mounts. The windscreen wiper failure from 2025 is a minor but necessary repair, as effective windscreen clearance is essential for safety. Finally, given the vehicle’s age and mileage, consider a comprehensive fluid check, including the brake fluid, coolant, and transmission fluid, as these fluids degrade over time and can lead to system failures if not replaced. A professional inspection should also verify the battery health, as older vehicles with low mileage can suffer from standing corrosion or internal failure, which may not be apparent during a test drive. Prioritise addressing the coil spring and brake system issues first, as these are the most critical components with a history of failure.
