Driving a 2018 Infiniti QX60 offers a blend of luxury, space, and refined performance that is hard to ignore in the three-row SUV segment. As a near luxury brand, Infiniti provides a premium experience with plush materials, a quiet cabin, and smooth V6 power. However, ownership over the years reveals that even this sophisticated machine is not immune to specific design flaws, electronic gremlins, and maintenance quirks that potential buyers must understand.
Overview of the 2018 Model Year
The 2018 Infiniti QX60 arrived with subtle updates, including a revised grille, new wheel designs, and enhanced safety technology packages. Under the hood, the reliable 3.5-liter V6 producing 260 horsepower remained the standard, paired with a smooth CVT transmission. While the powertrain is generally robust, the model year sits in the middle of the QX60's production run, meaning it inherits issues from earlier years while not yet benefiting from later engineering fixes.
Common Mechanical and Electrical Issues
Owners of the 2018 QX60 frequently report a cluster of specific problems that define the ownership experience. These issues range from minor annoyances to significant repairs that can impact reliability and long-term value. Being aware of these problems is the first step for any prospective buyer to make an informed decision.
CVT Transmission Hesitation and Failure
The Continuously Variable Transmission (CVT) is a signature feature of the QX60, offering seamless power delivery and efficiency. However, this design has proven to be a weak point for many owners. Complaints of shuddering, slipping, and delayed engagement are common. In more severe cases, the transmission can fail entirely, leading to expensive repairs or replacement costs that rival the vehicle's actual market value.
Electrical System Malfunctions
The QX60's complex infotainment and sensor systems are a frequent source of frustration. Owners often deal with unresponsive touchscreens, random resets, and difficulty pairing smartphones. More concerning are issues with the rearview camera freezing or failing to activate, which poses a safety risk when reversing. These electrical gremlins can be intermittent, making them difficult for mechanics to diagnose and repair.
Engine Oil Dilution and Consumption
A particularly serious issue found in the 2018 model involves the engine's oil supply. Short-trip driving patterns cause fuel to condense and mix with the engine oil, leading to significant dilution. This thins the oil, reducing lubrication and increasing the risk of premature engine wear. Some owners also report excessive oil consumption, where the engine burns oil at an abnormal rate, leading to low oil levels and potential damage if not monitored meticulously.
Interior and Design Quirks
Beyond the mechanics, the 2018 QX60 has several design choices that impact daily usability. The center console layout, while stylish, can be awkward for accessing climate controls or storage compartments. The third-row seating, while present, are best suited for small children or occasional use, as adult passengers may find the space cramped and uncomfortable on longer trips.
Maintenance and Repair Considerations
Owning a luxury vehicle requires a commitment to its specific maintenance schedule, and the QX60 is no exception. Using incorrect fluids, particularly in the CVT transmission, can drastically shorten its lifespan. Furthermore, finding a qualified mechanic familiar with Infiniti's specific systems is crucial. Aftermarket parts can be difficult to source, and dealer repairs, while correct, can be costly. Staying on top of oil changes and fluid flushes is the single best way to mitigate the risk of major mechanical failures.
