Summary Verdict
The 2014 INFINITI Q50 presents a generally reliable profile, particularly with its standard 3.7L V6 engine. However, owners of the hybrid model should be aware of potential battery degradation and inverter cooling pump issues, which can be costly to repair. The 7-speed automatic transmission can sometimes exhibit harsh shifting or leaks, requiring attention. For models equipped with the Sport Chassis and Direct Adaptive Steering, steering system malfunctions are a notable concern. Electrical gremlins, primarily related to the infotainment system and occasional battery drain, are also reported. Overall, while not plagued by widespread critical failures, potential buyers should consider these specific areas when evaluating a used 2014 Q50.
