2018 Infiniti Q30 2.1L Diesel · NJ18 LGO

The vehicle maintains a roadworthy status, though the maintenance trend shows a slight shift toward age-related wear issues. The most recent test conducted in August 2025 at 26,904 miles passed but introduced the first recorded advisories since the vehicle was new. This marks a departure from the clean records seen in previous years, indicating that the car is now beginning to require attention on components affected by time rather than just mechanical usage. The mileage pattern is exceptionally low for a 2018 model, averaging approximately 3,300 miles per year. Between September 2021 at 13,102 miles and August 2025 at 26,904 miles, the vehicle covered only 13,802 miles over four years. This consistency suggests infrequent use, which generally preserves the drivetrain and suspension geometry. However, such low mileage often correlates with the degradation of rubber-based components and tyres as they dry out and crack over time despite having significant tread depth. A buyer must prioritise a physical inspection of the rear tyres, as the August 2025 test flagged cracking and perishing on both sides. This is a common symptom of low-mileage vehicles sitting for extended periods where the rubber loses elasticity. The tester also noted that the front brake discs are worn during this same inspection. While not a failure point, the buyer should check for surface rust or uneven pitting which can occur when brakes are not used frequently enough. The structural integrity appears sound based on the lack of corrosion-related advisories across the five-year history. The fit of undertrays in August 2024 at 21,795 miles suggests proactive protection of the underbody. Given the clean history from 2021 through 2023, the primary concerns remain the age-related condition of consumables and the state of the braking hardware rather than systemic mechanical failure or structural neglect.
