2018 Infiniti Q50 2.1L Diesel · NJ18 LFN

The vehicle is currently roadworthy following a PASS on 2025-07-02 at 109,674 miles, but the maintenance trend shows a concerning deterioration in mechanical integrity over the past year. The most recent test identified persistent issues with both rear anti-roll bar linkage ball joints exhibiting slight play—this was first flagged in June 2025 and had already been recorded in the prior failed test from June 2025, indicating a failure to address a known defect. Additionally, the headlamp aim and levelling system remain unresolved, with both front headlamps still too low and the levelling device inoperative, suggesting ongoing electrical or mechanical faults in the lighting system that could compromise night-time visibility. The mileage accumulation is notably high for an eight-year-old vehicle, averaging approximately 13,709 miles per year. This rapid wear pattern is evident in the jump from 71,005 miles in June 2023 to 91,247 miles by June 2024—a gain of 20,242 miles in just one year—followed by another 18,427 miles within the next 12 months. Such sustained high usage accelerates wear on critical components such as suspension bushes, brake discs, steering linkages, and drivetrain elements, particularly given the repeated suspension-related defects. The absence of any defects in the two prior MOTs (June 2023 and June 2024) suggests a sudden escalation in mechanical degradation, likely due to deferred maintenance or harsh driving conditions. A buyer must conduct a thorough in-person inspection of the suspension system, focusing on all anti-roll bar linkages, control arms, and associated bushings, which have shown recurring signs of wear. The presence of ply or cords exposed on the offside front tyre during the June 2023 failure indicates poor tyre management, raising concerns about overall vehicle care. Brake performance should be verified, especially given the high mileage and potential for warped discs or binding calipers. Structural integrity should also be assessed, though no corrosion or frame damage has been reported; however, the high mileage and history of suspension fatigue warrant checking for hidden rust in underbody areas, wheel arches, and chassis rails. The unresolved headlamp issues further suggest possible wiring or sensor faults requiring diagnostic attention before purchase.
