2012 Infiniti FX30D Auto 3.0L Diesel · SF62 CLZ

The vehicle presents a concerning roadworthiness profile with a maintenance trend moving towards structural and electrical neglect. While the most recent MOT test in November 2025 at 100,663 miles passed, it followed an immediate failure involving an inoperative engine management light, a failed registration plate lamp, and a worn offside rear tyre. The presence of corrosion on the rear sub-frame is a significant finding that, although not classified as a serious failure at the time, indicates the onset of structural degradation that will accelerate if not monitored or treated. The mileage pattern is relatively consistent for a vehicle of this age, averaging approximately 7,200 miles per year. However, there is a notable surge in usage between December 2023 at 72,309 miles and November 2024 at 86,330 miles, where the car covered over 14,000 miles in under eleven months. This period of higher use correlates with the appearance of mechanical and electrical defects shortly after a long stretch of clean records, suggesting the vehicle has recently been subjected to more rigorous road conditions which may have likely accelerated the wear on rubber components and lighting elements. A buyer must conduct a thorough physical inspection of the rear sub-frame to assess the depth of the reported corrosion, as surface rust often masks deeper structural thinning in these chassis components. The history shows previous issues with steering rack bushes and ball joint play dating back to 2018, so the entire suspension geometry should be checked for excessive play or perished bushings. Furthermore, the failure of the engine management light in the 2025 test necessitates a diagnostic scan to ensure no hidden fault codes remain in the ECU, as a pass only confirms the light is now functional rather than the engine being mechanically perfect.
