Summary

The 2014 INFINITI Q50 has a mix of potential issues. Engine issues, such as oil consumption and timing chain tensioner problems, can be costly to fix. Transmission issues, particularly with the valve body and torque converter, are also common. Electrical problems, especially with the InTouch infotainment system, are a frequent source of frustration. Suspension issues, like premature bushing wear and Direct Adaptive Steering problems, add to the potential maintenance costs. While not all Q50s will experience these issues, prospective buyers should be aware of them and have a pre-purchase inspection performed to assess the car’s condition. Overall, these issues range from moderate to severe in terms of repair cost and potential impact on vehicle reliability.
