2014 Infiniti Q50 2.1L Diesel · RV64 HBJ

The vehicle remains roadworthy as of its most recent MOT on 2025-10-22, but the maintenance trend is worsening. While the 2024 and 2023 tests were clean, the 2025 test revealed three issues: a rear oil leak (not excessive), two front tyres worn to the legal limit with edge damage, and a persistent issue with both rear anti-roll bar linkage ball joints showing slight play. This indicates a failure to resolve or replace worn suspension components over multiple years, suggesting a pattern of deferred maintenance rather than proactive care. Mileage progression is consistent with the vehicle’s age — 73,590 miles over 12 years equates to roughly 6,132 miles annually, which is within normal parameters for a used luxury sedan. The gap between MOTs is consistently around 12 months, with no evidence of rapid mileage accumulation or long periods of inactivity. The 2021 test at 37,145 miles and the 2025 test at 73,590 miles show a steady, predictable increase, suggesting the car has been regularly driven but not overused. The absence of major defects in the 2024 test implies a temporary reprieve, not a fundamental fix. Buyers should inspect the rear anti-roll bar linkages closely, as the ball joints have shown slight play in every test since 2021, indicating progressive wear or lack of replacement. The front tyres, repeatedly flagged as worn to the legal limit, suggest either uneven wear or neglect of rotation and alignment. The rear oil leak, while not excessive, should be traced to its source — a common issue in this model, often linked to gasket or seal degradation. Brake calipers and discs should be checked for binding or uneven wear, especially given the recurring tyre issues, which may point to underlying suspension misalignment. Structural corrosion, particularly around wheel arches and underbody, should also be examined, as these are common failure points in this age group of vehicles. The car’s mechanical condition reflects a history of deferred attention to suspension and tyre maintenance, with no major structural or safety-critical failures recorded. A buyer should budget for immediate tyre replacement and a full suspension inspection, particularly the anti-roll bar joints and associated bushes. The oil leak should be assessed for potential progression, and the exhaust and emissions system should be verified for compliance, as these are often overlooked in older vehicles with high mileage.
