Driving a 2015 Infiniti Q50 offers a blend of sporty performance and luxury that is hard to ignore. The sedan’s aggressive design, responsive steering, and plush interior make it a compelling choice in the near-luxury segment. Yet, like any complex machine, this specific model year is not without its share of mechanical and electronic gremlins that owners have come to terms with over time.
Recalling the Model Year Context
The 2015 model year was a significant one for the Infiniti Q50, as it marked the introduction of the brand’s new Q50 line of sedans. This generation brought a radical change from the previous G37, featuring a more modern design language and a shift toward advanced technology. The promise of a digital dashboard and a suite of driver-assistance features generated considerable buzz. However, the rush to innovate sometimes led to teething problems that manifested after the vehicle left the dealership.
Common Electrical and Infotainment Issues
One of the most frequently reported issues with the 2015 Q50 revolves around its electronics. Owners often complain about the malfunctioning of the Infiniti InTouch system, which controls the navigation, audio, and climate settings. The interface can be sluggish, and in some cases, the system crashes or fails to respond to touch inputs entirely. This glitch often necessitates a visit to the dealer for a software update or, in more severe instances, a replacement of the head unit.

Mechanical Underbody Concerns
Beyond the digital dashboard, the 2015 Q50 suffers from some traditional mechanical ailments that affect the driving experience. The suspension setup, while tuned for a sporty feel, can be overly firm for some passengers, leading to a jarring ride on rough roads. Furthermore, the turbocharged variants of the engine, specifically the 3.7-liter V6, have shown a propensity for issues if not maintained meticulously.
Engine and Transmission Nuances
Under the hood, the Q50 relies on the VQ37VHR V6 engine. This powerplant is generally robust, but it is not immune to issues. Some owners have reported a faint knocking or ticking noise emanating from the engine bay, often attributed to the direct injection system or the variable valve timing mechanism. While sometimes benign, this noise can be indicative of future complications if left unchecked. The automatic transmission, paired with the AWD system, has also been known to exhibit harsh shifting behavior in certain driving conditions, which can disrupt the otherwise smooth ride quality.
The Steering System Mystery
Perhaps the most concerning issue documented by Consumer Reports and owner forums alike is the sudden loss of steering assist. Owners have described scenarios where the steering wheel becomes excessively heavy, making parking and low-speed maneuvering dangerous. This issue is often electrical in nature, stemming from the power steering pump or its associated sensors. Unlike a hydraulic system that warns of failure with a leak, an electrical issue can appear without warning, catching drivers off guard.
Maintenance as a Preventative Measure
For the discerning owner of a 2015 Infiniti Q50, proactive maintenance is the single best defense against these common problems. Staying on top of the factory service schedule is crucial. This includes regular oil changes with the correct synthetic viscosity, timely transmission fluid flushes, and inspections of the suspension components. Addressing minor electrical gremlins immediately can prevent them from cascading into major system failures that require expensive dealer visits.
