2014 Infiniti Q50 2.1L Diesel · MW63 TFK

The vehicle currently holds a roadworthy status, but the maintenance trend shows a worsening condition regarding suspension components. While the most recent test in December 2025 at 109,504 miles passed, it followed a failure just ten days prior at 109,324 miles. The failure for excessively worn front lower suspension arm ball joints and persistent play in both rear anti-roll bar linkage ball joints indicates that while the immediate faults were addressed, the overall suspension assembly is reaching a stage of significant component degradation. The recorded mileage of 109,504 miles over 12 years represents an average usage of approximately 9,125 miles per year, which aligns with typical UK figures for this age. The data shows a significant increase in activity between January 2024 (89,562 miles) and January 2025 (101,220 miles), covering over 12,000 miles in a single year. This period of higher intensity likely contributed to the wear observed on the suspension and braking components noted in the subsequent 2025 test results. A buyer must conduct a thorough physical inspection of the front suspension geometry, specifically checking the lower arm ball joints and bushings for further play, as these have appeared as recurring issues across multiple recent tests. The history of thinning brake pads and worn rear discs dating back to 2023 and 2024 suggests that the braking system may be nearing the end of its service interval. Additionally, verify that the windscreen washer system, which caused the early December 2025 failure, has been properly repaired and functions correctly.
