2015 Infiniti Q50 2.1L Diesel · NJ15 OKG

The 2015 INFINITI Q50 presents a mixed maintenance picture, with the most recent MOT on 23 May 2026 at 110,264 miles passing but flagging inner edge wear on both front tyres. This is a notable shift from the clean pass recorded on 31 May 2024 at 82,799 miles, suggesting the car has covered significant mileage in a short period and that basic consumable upkeep may have been deferred. The trend is not clearly worsening, but it is not stable either. A fractured nearside front coil spring and corroded subframe mounting were identified in the May 2025 test cycle, and while the car passed its most recent inspection, those structural and suspension items have not been explicitly rechecked or confirmed resolved. The mileage accumulation tells a clear story. Between 31 May 2024 and 28 May 2025, the car added 11,730 miles, and in the following twelve months to 23 May 2026 it added a further 15,735 miles. That jump from roughly 82,800 to 110,264 miles in just over two years is well above the 10,000 miles per year average typical for this age. Rapid accumulation at this stage places additional stress on suspension bushes, brake components, drivetrain mounts, and cooling system parts, all of which wear proportionally with use rather than age alone. A buyer should pay close attention to the front suspension and subframe area. The fractured coil spring noted on 10 May 2025 at 93,116 miles is a serious defect that should have been replaced, but the subsequent pass on 28 May 2025 does not confirm whether the repair was carried out or whether the advisory subframe corrosion has progressed. The nearside front coil spring and both front lower subframe mounting points need physical inspection for fresh paint, welding marks, or ongoing corrosion. The anti-roll bar linkages flagged with slight play in May 2025 also warrant a check, as worn linkages can cause knocking over uneven surfaces and affect handling stability. The braking system requires similar scrutiny. The nearside rear brake pads were below 1.5 mm on 31 May 2024 at 82,796 miles, and with nearly 27,500 miles added since then, the condition of all brake pads, discs, and calipers should be verified. The long travel on the parkbrake pedal noted in May 2025 suggests the handbrake mechanism or rear brake adjusters may need attention. Combined with the recurring front tyre inner edge wear, which often points to worn suspension geometry or tracking misalignment, this car needs a thorough underbody and brake inspection before purchase.
