2012 Infiniti FX50 S Auto 3.0L Diesel · YJ62 MWC

The most recent MOT test for this 2012 Infiniti FX50 S Auto was conducted on 2023-02-10 and resulted in a clean pass, indicating no defects were recorded. However, the vehicle’s MOT history reveals a pattern of recurring advisories related to anti-roll bar linkages, with slight play noted in both the front and rear ball joints in 2018 and 2015, alongside a single failure in 2016 concerning brake efficiency and the tyre pressure monitoring system. While the advisories from 2015 and 2018 were not classified as failures, their persistence suggests that the suspension components may be approaching end-of-life or experiencing cumulative wear. The absence of failures in the intervening years implies that maintenance has been consistent, but the advisories warrant closer attention, particularly as the vehicle’s age and mileage increase. The recorded mileage of 129,375 miles for a vehicle aged approximately 14 years represents a reasonable annual usage rate of around 9,241 miles per annum, which aligns with typical expectations for this class of car. There is no evidence of rapid mileage accumulation or excessive wear from high annual mileage alone, but the consistent anti-roll bar advisories may indicate that the suspension has been subjected to prolonged stress, potentially from frequent cornering or rough road conditions. The lack of significant gaps in the MOT schedule suggests the vehicle has been driven regularly, though the advisories could imply that the anti-roll bars and their linkages are nearing the point where further wear or failure is more likely. This is particularly relevant given the wear progression of ball joints and potential stiffness in coil springs or struts over time. For a prospective buyer, the most critical areas to inspect are the suspension components, particularly the anti-roll bars and their linkages, as the advisories suggest ongoing play or degradation. On a test drive, listen for unusual suspension clunks or rattles, especially when cornering or over bumps, which may indicate failing ball joints or loose components. Visually inspect the anti-roll bars for signs of corrosion or bending, and check for uneven tyre wear patterns, which could suggest misalignment or suspension issues. Additionally, verify the brake system by ensuring smooth pedal response and listening for grinding or squealing noises during braking, as the 2016 failure highlighted potential brake efficiency concerns. A thorough inspection of the brake discs and calipers for corrosion or binding is also essential, particularly if the vehicle has been stationary for extended periods, as standing can accelerate rust formation. Beyond the suspension and brakes, given the vehicle’s age and mileage, focus on fluid condition and tyre integrity. Check the engine oil, transmission fluid, and coolant for signs of degradation or contamination, as these fluids should be replaced according to the manufacturer’s schedule, typically every 60,000 to 100,000 miles or every 12 months, whichever comes first. Inspect the tyres for sidewall cracking or perishing, which can weaken the structure and compromise safety, especially if the vehicle has been in storage or driven lightly. Test the 12V battery for voltage output and overall health, as older vehicles are more prone to battery failure, particularly if the alternator is not functioning optimally. Finally, ensure the exhaust system is free of leaks or corrosion, as emissions-related failures can occur if the catalytic converter or mufflers have degraded over time. A comprehensive pre-purchase inspection by a qualified mechanic would be advisable to confirm the advisories’ severity and plan for any necessary repairs before purchase.
