2017 Infiniti Q50 2.1L Diesel · RO17 WVR

The most recent MOT inspection on 17 June 2024 resulted in a pass with no recorded defects, which suggests that the significant mechanical issues identified in previous years have been addressed. Looking at the wider maintenance trend, the vehicle has experienced a period of instability between 2020 and 2023, characterized by failures related to braking components, tyre integrity, and suspension wear. However, the transition from a dangerous failure in 2020 and a major suspension failure in 2023 to a clean pass in 2024 indicates an improving maintenance trajectory, suggesting that the owner has likely responded to the MOT advisories and failures by carrying out necessary repairs. With 132,269 miles recorded over approximately nine years, this Infiniti Q50 has averaged roughly 14,700 miles per year. This is considered high-average to high mileage for a premium executive vehicle of this age. While this level of usage typically indicates regular motorway driving, which can be less taxing on certain engine components than short urban trips, it necessitates a rigorous inspection of high-wear consumables. The cumulative mileage means that major service intervals for timing chains, turbocharger components (if applicable), and complex drivetrain elements are likely approaching or have already passed, making a comprehensive service history review essential to ensure the vehicle has not been run on extended or neglected intervals. Prospective buyers should pay close attention to the suspension and exhaust systems during a test drive. The 2023 MOT history highlighted corrosion on a rear suspension component and a defective rear exhaust mounting. You should listen for any rhythmic thumping, clunking, or knocking sounds when driving over uneven surfaces or speed bumps, which could indicate that the previous suspension ball joint failures or corrosion issues have not been fully rectified or that other bushes and joints are now failing. Furthermore, check the exhaust system for excessive vibration or rattling, particularly when the engine is under load or when idling, as this could signal that the mounting issues persist or that the structural integrity of the exhaust hangers is compromised. Given the high mileage and the history of tyre and brake-related advisories, a thorough physical inspection of the running gear is mandatory. Examine the tyres for uneven wear patterns, particularly on the inner and outer edges, which would suggest underlying alignment or suspension geometry issues. Check the brake discs for deep scoring or significant lip formation and listen for any squealing or grinding that might indicate worn pads or sticking calipers. Additionally, since the vehicle has seen significant use, inspect the engine bay for any signs of fluid weeping from gaskets or seals, and verify that the service book contains consistent stamps to confirm that the high mileage has been met with appropriate preventative maintenance rather than reactive repairs.
