2018 Infiniti QX30 2.1L Diesel · SJ18 XGX

The 2018 INFINITI QX30 presents a stable and improving maintenance trend, culminating in a notably clean bill of health. The most recent MOT, conducted on 31 May 2025 at 67,883 miles, passed with zero defects recorded. This is a significant improvement over the preceding two tests, which both flagged worn and pitted brake discs across all four corners. The absence of any advisories or failures in the latest test suggests that the braking system has been properly overhauled, with discs and pads likely replaced to address the recurring pitting noted in 2023 and 2024. The mileage accumulation of approximately 8,485 miles per year is entirely typical for an eight-year-old vehicle and indicates consistent, regular use rather than prolonged standing or excessively hard driving. The annual MOT intervals are well-spaced, with each test occurring roughly twelve months apart, and the mileage jumps between tests are steady and predictable: 7,105 miles between June 2023 and June 2024, and 7,105 miles again between June 2024 and May 2025. There are no suspicious gaps or sudden spikes in the odometer record that would raise concerns about clocking or extended periods of disuse. Despite the clean 2025 result, a prospective buyer should still carry out a focused physical inspection of the braking system. The repeated pitting on all four brake discs in both the June 2023 test at 53,797 miles and the June 2024 test at 60,778 miles points to a pattern of disc corrosion or aggressive pad wear that may have been climate-related or driven by the owner's driving style. Check the current discs for any signs of lipping, scoring, or uneven wear, and verify that the pads have adequate remaining material. The rear tyres were flagged as worn close to the legal limit in 2023, so inspect the current tyres for edge wear, which can indicate misaligned tracking or worn suspension bushes. Given the vehicle's age and the history of brake-related advisories, it would also be prudent to examine the underside for any signs of corrosion on brake lines, subframe mounting points, and suspension components, particularly if the car has been used in areas where road salt is prevalent.
