Editorial Take

These three large SUVs, while appearing in different segments at first glance, often find themselves on the same shopping lists for families prioritizing space, comfort, and hauling capability. The 2019 Ford Explorer offers a strong balance of everyday practicality, advanced features, and a range of engine options in the popular mid-size crossover segment. The 2017 and 2018 Infiniti QX80 represent a more traditional, truck-based full-size luxury SUV, appealing to buyers needing substantial towing power, ultimate passenger comfort, and a distinctly upscale experience. Key decision factors include budget, required towing capacity, desired level of luxury, interior space, and fuel efficiency expectations. HEAD-TO-

Reliability & Common Issues

2019 Ford Explorer: 1. Transmission issues: Some owners have reported rough shifting, hesitation, or premature failure of the 6-speed automatic transmission, particularly around the 60,000-80,000-mile mark. 2. Water pump leaks (3.5L V6): The internal water pump on the 3.5L V6 engine can fail and leak coolant internally, potentially leading to engine damage if not addressed, often affecting vehicles around 70,000-100,000 miles. 3. Electrical glitches: Minor complaints about infotainment system freezes (SYNC 3), erratic warning lights, or power liftgate malfunctions. 2017 Infiniti QX80: 1. Fuel gauge inaccuracy: Some owners have reported the fuel gauge occasionally providing inaccurate readings or sticking at certain levels. 2. Minor electrical quirks: Isolated reports of infotainment system freezing or Bluetooth connectivity issues, though generally less severe than some Ford issues. 3. Brake pulsation: Some owners have experienced premature brake rotor warping leading to pulsation, particularly in the front, sometimes requiring replacement around 30,000-50,000 miles. 2018 Infiniti QX80: 1. Similar to the 2017 model, the 2018 QX80 shares most mechanical components, so it can experience similar, though generally minor, issues like the occasional fuel gauge anomaly or brake pulsation. 2. Infotainment system: While refreshed, some users still found the Infiniti InTouch system less intuitive or slower than more modern competitors, especially compared to systems with standard Apple CarPlay/Android Auto (which the QX80 lacked).

Value & Cost of Ownership

When new, the Ford Explorer was significantly more affordable, with base models starting around $32,000, while the QX80 commanded prices upwards of $64,000. On the used market, a 2019 Ford Explorer with average mileage (50k-70k miles) can typically be found for $15,000-$25,000, depending on trim and condition. A 2017 Infiniti QX80 with similar mileage might range from $25,000-$35,000, and a 2018 QX80, due to its refresh, could be $28,000-$38,000. These are general estimates and vary widely by location and specific vehicle condition. Insurance costs for the QX80 will generally be higher due to its higher original MSRP, luxury designation, and more expensive parts. Maintenance costs for the Explorer are typically lower, as it uses more common parts and labor rates are generally lower for Ford dealerships and independent mechanics. The QX80, being a luxury vehicle, will have higher parts costs and require more specialized service, leading to increased maintenance expenses. Fuel costs will also be considerably higher for the QX80 due to its V8 engine's lower fuel economy and requirement for premium fuel (though it can run on regular). Resale value for both models tends to be average. The Explorer holds its value decently in the mid-size segment, while the QX80, like many large luxury SUVs, experiences significant initial depreciation but then holds a more stable value.

Editorial Verdict

BEST FOR FAMILIES: The 2018 Infiniti QX80. While the Explorer is a strong contender, the QX80 offers superior third-row comfort, more overall cargo space, a more luxurious cabin for long trips, and impressive towing capacity for family campers or boats. The 2018's interior refresh is a nice bonus. BEST FOR COMMUTERS: The 2019 Ford Explorer. Its more car-like driving dynamics, better fuel economy (especially with the 2.3L EcoBoost), and smaller footprint make it more manageable in city traffic and easier to park than the much larger QX80. BEST FOR ENTHUSIASTS: Neither vehicle is truly an "enthusiast" choice in the traditional sense. However, for those who appreciate robust power, the QX80's 5.6L V8 delivers a satisfying surge of torque. If quick acceleration in a more agile package is preferred, the Explorer with the 3.5L EcoBoost V6 might offer a more engaging drive. BEST VALUE OVERALL: The 2019 Ford Explorer. It offers a strong balance of practicality, features, and comfort at a lower initial purchase price and lower running costs. While it lacks the luxury presence of the QX80, its versatility and efficiency make it a more sensible overall value proposition for most buyers. If luxury and towing are paramount, a well-maintained 2017 QX80 offers significant luxury for a depreciated price.
