2018 Infiniti Q50 2.1L Diesel · NJ18 LDX

The 2018 Infiniti Q50 presents a stable and improving maintenance trend, culminating in a fully clean MOT pass on 3 February 2026 at 63,518 miles with zero defects recorded. This is a significant improvement over the January 2025 test at 53,874 miles, where the tester flagged multiple issues including slight play in both front lower suspension arm ball joints, fluctuating service brakes on the offside front and rear, a binding nearside rear brake, and front outer brake pads wearing thin. The fact that all these defects were rectified before the most recent test suggests the previous owner addressed the mechanical concerns promptly. The vehicle has not failed an MOT since February 2023, when both front tyres were below the 1.6mm legal tread depth minimum, a straightforward consumable issue that was also resolved. The mileage accumulation of roughly 7,940 miles per year over eight years is typical for this age of vehicle and indicates consistent regular use rather than prolonged standing or excessive wear. The recorded intervals show a steady progression from 37,941 miles in February 2023 to 43,908 miles in January 2024, then to 53,874 miles in January 2025, and finally to 63,518 miles in February 2026. There are no suspicious gaps or sudden jumps in the odometer readings that would raise concerns about clocking or extended periods of inactivity that could cause deterioration of seals, rubber components, or brake surfaces through corrosion. A buyer inspecting this vehicle in person should pay close attention to the front suspension, specifically the lower arm ball joints that were flagged for slight play in January 2025. Check for any clunking from the front end over speed bumps or during low-speed turning, which could indicate the play has returned. The braking system also warrants careful inspection. The previous advisories on binding rear calipers, fluctuating brakes, and worn front pads suggest the braking components have experienced uneven stress. Have a technician measure brake disc thickness and run-out, and confirm the rear caliper slides and pistons are free-moving. Inspect the condition of the front tyres, as the 2023 failure for low tread depth on both fronts hints at possible alignment or suspension geometry issues that could cause uneven wear patterns. Finally, examine the underside for any signs of corrosion on subframes, suspension mounting points, and brake lines, particularly given the vehicle is now eight years old and may have been exposed to road salt without undersealing.
