2018 Infiniti Q30 2.1L Diesel · NJ18 LGD

The 2018 INFINITI Q30 presents a stable and improving maintenance trend, culminating in a clean pass on 27 March 2026 at 44,144 miles with zero defects recorded. That result marks the first completely advisory-free MOT in the vehicle's history, suggesting recent attention to previously flagged items. The trajectory from recurring tyre and brake disc advisories in earlier years to a spotless outcome today indicates resolving rather than worsening faults. Mileage accumulation tells a story of two distinct phases. Between the April 2022 test at 17,758 miles and the March 2024 test at 25,014 miles, the car covered roughly 7,256 miles in two years, averaging around 3,600 miles annually. Then the pace picked up sharply: from March 2024 to March 2026, the odometer jumped from 25,014 to 44,144 miles, adding 19,130 miles in just over two years. That equates to roughly 9,000 miles per year, nearly double the earlier rate. The gap between the 2025 and 2026 tests alone accounts for 8,951 miles in twelve months, confirming the car is now being driven more intensively than at any prior point in its life. The recurring tyre condition advisories from 2022 and 2023, covering cracking and perishing across all four wheels, point to a period where the vehicle may have sat unused or been fitted with aged rubber. These have since been resolved, but a buyer should still inspect the current tyre date codes and sidewall condition carefully, particularly if the car has spent extended periods stationary between uses. The worn and pitted brake discs flagged on the front and offside rear in April 2022 also warrant a physical check. While the clean 2026 result implies replacement or sufficient remaining thickness, corrosion on mounting surfaces, uneven pad wear, or binding calipers can develop between MOT intervals and would not appear in the record. The engine covers and undertrays noted in 2022 obscured testable items during that inspection, meaning structural rust, fluid leaks, or subframe condition could not be fully assessed at that time. A buyer should arrange an independent inspection that includes removal of undertrays to examine the subframe, suspension mounts, and exhaust system for corrosion or damage, particularly given the low-mileage early years that may have involved short trips promoting moisture retention.
