Editorial Take
These three large luxury SUVs appeal to buyers seeking immense passenger and cargo capacity, commanding road presence, and premium amenities. The 2015 and 2017 Infiniti QX80 represent the Japanese take on full-size luxury, emphasizing V8 power and a distinctive, opulent interior. The 2017 Lincoln Navigator offers a more traditional American luxury experience, with a focus on spaciousness, a robust turbocharged V6, and a softer ride. Key decision factors among these vehicles include engine preference, interior design and technology, third-row usability, and long-term reliability expectations. HEAD-TO-
Reliability & Common Issues
2015 Infiniti QX80: A common complaint for this generation involves premature wear of brake components, including rotors, pads, and sometimes calipers. Owners have reported needing brake services more frequently than expected, sometimes as early as 20,000-30,000 miles. Infotainment system glitches, such as freezing or slow responses, were also reported, though often resolved with software updates. 2017 Infiniti QX80: Similar to the 2015 model, the 2017 QX80 can suffer from premature brake wear. While not as widespread, some owners have also reported issues with the liftgate struts failing prematurely, leading to the power liftgate not staying open reliably. 2017 Lincoln Navigator: The 3.5L EcoBoost engine in the Navigator can be susceptible to carbon buildup on the intake valves over time, potentially leading to reduced performance or misfires, especially at higher mileage (e.g., beyond 70,000 miles). Turbocharger wastegate actuator issues are also known to occur, manifesting as a rattling noise or reduced boost. The air suspension system, while providing a comfortable ride, can develop leaks or compressor failures, particularly in older or higher-mileage examples, leading to expensive repairs.
Value & Cost of Ownership
When new, all three vehicles had comparable starting MSRPs in the mid-$60,000 range. However, significant depreciation has occurred across all models. Today, a 2015 Infiniti QX80 can be found for roughly $18,000-$25,000, while a 2017 QX80 typically commands $25,000-$35,000 depending on mileage and condition. A 2017 Lincoln Navigator also falls into the $25,000-$35,000 range. All are large luxury SUVs, meaning insurance costs will be higher than average due to repair costs and vehicle value. Maintenance costs for the Infiniti QX80 models are generally reasonable for a luxury vehicle. Infiniti parts can be specific, but the drivetrain is well-proven. The known brake wear issue can add to routine service expenses. The Lincoln Navigator, being a Ford product, benefits from widely available parts, but the EcoBoost engine and air suspension system can lead to more expensive specialized repairs if issues like carbon buildup or air strut failures occur. Fuel economy differences are slight, with the Navigator holding a marginal advantage. Resale value for this generation of Navigator depreciated heavily, making it a good used buy, while the QX80, though also depreciating significantly, often held a slight edge in value retention for its segment.
