Driving a 2018 Infiniti QX60 offers a blend of luxury, capability, and advanced technology that appeals to families and road enthusiasts alike. This mid-size luxury SUV, with its distinctive styling and comfortable interior, represents a strong value in the competitive premium segment. However, like any complex machine purchased used, it is essential to understand the specific 2018 Infiniti QX60 problems to ensure long-term satisfaction and avoid unexpected repair bills.
Overview of the 2018 Model Year
The 2018 model year arrived with significant updates for the QX60, including a revised grille, new LED lighting signatures, and enhanced safety features. Under the hood, buyers could choose between a standard 3.5-liter V6 producing 260 horsepower or a more powerful hybrid variant combining the V6 with an electric motor for 310 horsepower. While these powertrains provided a smooth and capable driving experience, specific design choices and component choices introduced issues that owners and potential buyers should be aware of.
Potential Engine and Transmission Concerns
Owners of the V6 models reported specific engine and transmission issues that impacted reliability. These concerns are critical to investigate during a pre-purchase inspection to gauge the long-term health of the vehicle.
CVT Transmission Hesitation: Some drivers noted a slight hesitation or "rubber band" feeling during acceleration, particularly in the hybrid models, which is characteristic of the Continuously Variable Transmission design.
Overheating Issues: There were isolated reports of the V6 engine running hotter than expected, which could stress components if not addressed promptly.
Hybrid System Alerts: Owners of the hybrid variant experienced warning lights related to the electric motor or battery system, requiring diagnostic checks at an authorized dealer.
Electronics and Infotainment Quirks
The QX60's modern infotainment system, while feature-rich, presented some challenges that affected user experience. Navigating the interface should be intuitive, but software glitches can turn a pleasant drive into a frustrating one.
Navigation System Lag: The built-in GPS occasionally suffered from slow response times or freezing, requiring a system reset while driving.
Bluetooth Connectivity Drops: Intermittent loss of Bluetooth connection between smartphones and the car's audio system was a common complaint, disrupting hands-free calling and music streaming.
Warning Light Malfunctions: Faulty sensors sometimes triggered dashboard warning lights incorrectly, causing unnecessary worry or trips to the mechanic.
Interior Comfort and Build Quality
Inside the cabin, the QX60 offers luxurious leather seating and a quiet ride, but material quality and construction reveal areas where compromises exist. Examining these details helps differentiate a well-maintained example from one that may have hidden wear.
Sunroof Leaks: A recurring issue involved the panoramic sunroof leaking, allowing moisture to seep into the headliner and interior panels during heavy rain.
Squeaks and Rattles: Loose interior panels or trim pieces often led to creaking noises over time, particularly on rough roads.
Seat Mechanism Wear: The power-adjustable front seats occasionally experienced electrical failures, such as sudden loss of power or uncomfortable lumbar support malfunctions.
Safety and Recall Information
Nissan, the parent company of Infiniti, issued several recalls for the 2018 QX60 to address safety-critical issues. Verifying the repair history of any used model is paramount for ensuring that all factory corrections have been applied.
Brake System Repair: A recall addressed a problem where the brake fluid could become contaminated, reducing braking effectiveness.
Seat Belt Pretensioner: Another recall fixed a potential issue where the front seat belt pretensioners might not deploy correctly in a collision.
