2012 Mazda 3 1.6L Petrol · OY12 JRZ

A recurring pattern of lighting and electrical defects defines the recent history of this vehicle, though it maintains a baseline of mechanical roadworthiness. While the latest test on 2026-02-21 resulted in a pass, it was only achieved after addressing major failures regarding the condition, compatibility, and aim of both headlamps. This trend of lighting issues, combined with previous failures for registration and position lamps, suggests a vulnerability in the external electrical system that requires close attention. With 107,609 miles recorded over fourteen years, the vehicle has averaged approximately 7,686 miles per year, which is consistent with typical UK usage patterns. This steady accumulation suggests the car has been used regularly rather than sitting for extended periods, which generally helps maintain seal integrity and prevents the stagnation of fluids. However, at this mileage, wear on chassis consumables and engine seals becomes more prevalent, as evidenced by the appearance of oil leaks in the records. Particular attention should be paid to the rear suspension, specifically the offside rear anti-roll bar linkage which was flagged for play and a slight knock during the March 2025 inspection. During a test drive, listen for rhythmic knocking or clunking sounds when traversing uneven road surfaces or during low-speed cornering, as this indicates the linkage has deteriorated further. Additionally, the recorded non-excessive oil leak warrants a physical inspection of the engine bay and the underside of the chassis for fresh residue or dripping. Given the history of headlamp lens defects and compatibility issues, ensure the current lighting units are genuine or high-quality replacements and that the beam pattern is consistent. Verify that the windscreen washer system is fully operational and that all external bulbs are functioning correctly, as these have been recurring points of failure. Check the engine oil level and monitor for any scent of burning oil during the drive, which would indicate the previously noted leak is impacting the exhaust manifold or other hot engine components.
