2015 Infiniti Q50 2.1L Diesel · RF15 KVT

The vehicle achieved a clean pass on 4 November 2025 at 74,174 miles, leaving roughly seven months until the next MOT is due. This recent success contrasts sharply with the mechanical state in early 2025, where the car failed on 24 January at 70,553 miles due to exposed tyre cords, leaking rear shock absorbers, and insufficient rear braking effort. The trend has shifted from deteriorating to stable, as the owner evidently rectified these serious defects shortly after the failure to secure a pass by 11 February 2025. Mileage accumulation sits at approximately 6,700 miles per year, aligning with typical usage for an 11-year-old vehicle. Records indicate a period of lower activity between November 2022 and January 2024, followed by intense use in early 2025 when the car covered over 1,100 miles in just 18 days between the January failure and February retest. The odometer increased by a further 2,462 miles between February and November 2025, suggesting regular driving following the major repair work. Inspectors flagged sub-frame corrosion in January 2025, so a physical check of the structural integrity is essential to ensure rust has not progressed beyond the previously noted surface level. The rear braking system requires particular attention, as the history shows a rapid transition from scored discs and pads under 1.5 mm thickness to a clean test; verify that replacement components are of high quality. Furthermore, examine the nearside rear shock absorber and anti-roll bar linkages to confirm the repairs for the fluid leak and ball joint play remain durable.
