The 2016 Infiniti QX50 represents a pivotal moment for the luxury crossover segment, marking the debut of the brand's first turbocharged engine. While it introduced a more dynamic driving experience than its predecessors, potential buyers need to be aware of specific 2016 Infiniti QX50 problems that can arise with this model year. Understanding these issues is crucial for ensuring a reliable and enjoyable ownership experience.
Recalls and Safety Campaigns
Like many vehicles of its era, the 2016 QX50 is subject to manufacturer recalls that address critical safety and performance issues. The most significant campaign involves the rear view camera display. In certain vehicles, the camera image could fail to display on the monitor, creating a serious blind spot when reversing. This issue stems from a software glitch or a loose connection within the infotainment system wiring, and it requires immediate attention from an authorized dealer to restore full functionality and safety.
Infotainment and Electrical System Quirks
Owners frequently report frustration with the 2016 model year's navigation and audio interface. The system is known for its slow boot-up times and occasional glitches that can temporarily disable touch functionality. Furthermore, some units experience intermittent electrical issues, such as random malfunctions of the power windows, seat adjustments, or the complete failure of the infotainment unit to power on. Diagnosing these problems often points to a faulty wiring harness or a defective module within the vehicle's complex electronic network.
Engine and Transmission Concerns
Turbocharged VC-Turbo Reliability
The 2.0-liter turbocharged VC-Turbo engine was a technological marvel, but it introduced specific challenges. While designed to be robust, some owners have experienced rough idling, hesitation during acceleration, or the illumination of the check engine light. These symptoms can be related to issues with the direct injection system, carbon buildup on the intake valves, or problems with the turbocharger wastegate actuator. Ignoring these signs can lead to more severe internal engine damage if a component fails completely.
Automatic Transmission Shudder
The 7-speed automatic transmission paired with the VC-Turbo engine is another area of concern. A common complaint is a pronounced shuddering or vibration felt during light acceleration, particularly between 25 and 45 mph. This issue is often attributed to inadequate transmission fluid circulation or the transmission control software's calibration. Inadequate maintenance or using the wrong fluid type can exacerbate this problem, making smooth gear changes difficult to achieve.
Exterior and Interior Wear
Beyond mechanical gremlins, the 2016 QX50 shows some signs of material quality that can affect longevity. The interior trim pieces, particularly the center console and door panels, are prone to developing creaks and rattles over time due to plastic fasteners weakening. Additionally, the panoramic sunroof, a popular feature, has been cited in some instances for leaks around the seal, potentially leading to water intrusion and damage to the headliner or carpeting.
Maintenance and Long-Term Ownership Tips
Proactive maintenance is the best defense against the 2016 Infiniti QX50 problems. Owners should strictly adhere to the recommended service schedule, paying close attention to transmission fluid and filter changes. Using high-quality synthetic oil is essential for the turbocharged engine's health. Regularly inspecting the wiring harnesses for chafing and ensuring all software updates are applied promptly can prevent many of the electronic gremlins that plague this model. For those considering a used example, a pre-purchase inspection focusing on the turbo system and transmission health is non-negotiable.
