The 2018 Infiniti QX60 occupies a unique space in the luxury crossover segment, blending distinctive styling with comfortable three-row seating. While the model year generally represents a reliable period for the platform, potential buyers should remain aware of specific 2018 Infiniti QX60 problems that can arise. Understanding these common issues helps owners maintain peak performance and prevents minor concerns from escalating into major repairs.
Common Mechanical and Electrical Issues
Among the most frequently reported 2018 Infiniti QX60 problems is the automatic transmission shuddering or hesitation during low-speed maneuvers. This often stems from software calibration issues or premature wear within the transmission modules, requiring a reprogramming or fluid service. Additionally, the 3.5-liter V6 engine, while powerful, can experience timing chain tensioner failures, leading to a rattling noise that demands immediate attention to prevent severe internal damage.
Electrical System and Infotainment Quirks
Electrical gremlins present another category of 2018 Infiniti QX60 problems that can frustrate owners. The infotainment system, featuring the hard-drive-based navigation, is notorious for slow boot times, unresponsive touchscreens, and occasional complete system freezes. Furthermore, loose wiring harnesses can cause random dashboard warning lights to illuminate, such as the stability control or check engine light, necessitating a visit to the dealer for diagnosis.
Interior Wear and Material Concerns
While the cabin offers ample space, certain 2018 Infiniti QX60 problems relate to interior durability. The second-row bench seat, while practical for families, can exhibit excessive sagging over time due to the foam construction, reducing passenger comfort on long trips. Hard plastics on the center console and door panels are prone to developing annoying creaks and squeaks as the vehicle ages, which can be distracting during quiet highway driving.
Proactive Maintenance Recommendations
Addressing these 2018 Infiniti QX60 problems early is crucial for longevity. Owners should prioritize regular transmission fluid exchanges using the manufacturer-specified fluid to mitigate shuddering and extend the transmission's life. Furthermore, staying current with software updates from the dealer can resolve many electronic glitches and ensure the infotainment system operates smoothly.
Safety and Reliability Ratings Context
It is important to contextualize these issues within the vehicle's overall safety profile. The 2018 QX60 generally received strong ratings from safety institutions, featuring standard advanced driver-assistance systems like lane departure warning and blind-spot monitoring. However, reliability scores from consumer reports often reflected the transmission and electronic concerns mentioned, placing it below some rivals in the long-term dependability charts.
Summary for Potential Buyers
For those considering a used 2018 Infiniti QX60, a thorough pre-purchase inspection is non-negotiable. Focus on verifying the transmission's performance through a test drive that includes stop-and-go traffic and highway merging. Scrutinize the electrical components, ensuring all sensors, cameras, and screens function correctly, and inquire about the maintenance history, specifically regarding the timing chain and transmission fluid service intervals.
