2015 Infiniti Q50 2.1L Diesel · RX15 OJM

The 2015 Infiniti Q50 presents a stable and improving maintenance trend, with the most recent MOT conducted on 13 August 2025 at 49,911 miles recording zero defects. This clean pass follows a similarly flawless test on 1 April 2025 at 48,868 miles, marking a clear resolution of the tyre wear issues that appeared in earlier records. The vehicle has remained consistently roadworthy across its recent testing history, suggesting attentive ownership over the past two years. The mileage accumulation tells a story of very light use. Covering roughly 4,537 miles per year over eleven years, this is well below the UK average. The annual increments between tests are modest: 2,846 miles between April 2024 and April 2025, and just 1,043 miles between April 2025 and August 2025. That sharp drop in the final interval could indicate the car has been standing for extended periods, which carries its own risks. Prolonged inactivity can lead to brake disc surface corrosion, tyre flat-spotting, and dried-out rubber seals, none of which the MOT necessarily flags unless severe. The 2023 test at 42,436 miles is the only entry recording advisories, and all four related to tyre condition. Both front tyres were worn close to the legal limit and worn on edge, indicating possible suspension geometry issues or simply neglected rotation. The rear tyres showed cracking and perishing, a condition often linked to age rather than mileage. The subsequent two clean passes suggest the owner replaced all four tyres, which is a positive sign. No recurring structural, braking, or suspension defects have appeared across the record. A buyer should still conduct a thorough in-person inspection focused on areas the MOT cannot fully assess. Check the underside for corrosion on subframes, suspension mounting points, and brake lines, particularly given the possibility of long stationary periods. Inspect the tyre dates and sidewalls for renewed perishing, and test the brakes for binding or uneven pull that surface corrosion might cause after short-use cycles. The nearside rear child seat advisory in 2022 and 2023 prevented full seatbelt inspection, so manually verify both rear belts retract and lock correctly. Overall, the record reflects a mechanically sound vehicle with no persistent faults, but the low-mileage pattern demands attention to deterioration from age rather than use.
