Editorial Take
The 2017 Infiniti QX80, 2017 Ford Explorer, and 2017 Ford Expedition represent three distinct takes on the SUV segment, often drawing comparisons from buyers seeking capable family vehicles, albeit with differing priorities. The Explorer appeals to those needing a three-row crossover with car-like manners and respectable fuel economy, often transitioning from sedans. The Expedition is the traditional, body-on-frame full-size SUV for maximum passenger and cargo capacity, plus serious towing. The QX80 offers a blend of full-size capability with a distinct focus on luxury, comfort, and premium amenities. Key decision factors among these three revolve around budget, desired level of luxury, required passenger and cargo space, towing needs, and fuel efficiency. HEAD-TO-
Reliability & Common Issues
2017 Infiniti QX80: 1. Fuel Gauge Sender Unit: Some owners have reported issues with the fuel gauge displaying inaccurate readings or failing completely, a common problem across certain Nissan/Infiniti models utilizing similar components. 2. Infotainment System Glitches: The InTouch infotainment system can occasionally experience freezing, slow response times, or connectivity issues with Bluetooth and navigation. 3. Premature Brake Wear: Due to its substantial curb weight (over 5,600 lbs), the QX80 can be prone to faster-than-average wear on brake pads and rotors, especially with aggressive driving. 2017 Ford Explorer: 1. Water Pump Failure: A known issue, particularly with the 3.5L V6 engine, where the internal water pump can fail. Because it's located inside the engine, repair can be very costly, often manifesting around 80,000 to 120,000 miles. 2. Electronic Power Assist Steering (EPAS) Issues: Some owners have experienced failures or intermittent problems with the electric power steering system, leading to a loss of power assist and the illumination of warning lights. 3. AC Compressor/Evaporator Leaks: Complaints of air conditioning systems losing their charge due to leaks in the compressor or evaporator core are not uncommon, resulting in diminished cooling. 2017 Ford Expedition: 1. Engine Misfires / Turbocharger Issues: While the 3.5L EcoBoost V6 is generally reliable, some units have experienced misfires due to carbon buildup on intake valves or issues with the turbocharger system, potentially leading to reduced power or check engine lights. 2. Transmission Shift Anomalies: Occasional reports of rough or delayed shifts from the 6-speed automatic transmission. These can sometimes be resolved with software updates, but in more severe cases, internal component issues may arise. 3. Power Running Board Malfunctions: The optional power-retractable running boards can sometimes seize or fail to deploy/retract properly due due to motor or sensor issues, particularly in areas exposed to harsh weather conditions.
Value & Cost of Ownership
When new, the Infiniti QX80 was the most expensive of the three, reflecting its luxury status. The Ford Explorer offered the lowest entry price, making it accessible to a wider range of buyers, while the Expedition sat in the middle, offering full-size capability at a non-luxury price point. In the used market today, a 2017 QX80 will still command a higher price than a comparable Explorer, but its luxury SUV depreciation rate means it has lost a significant percentage of its original MSRP, potentially making it an attractive used buy for those seeking luxury on a budget. Used Expedition prices tend to hold relatively well for a large SUV due to its robust nature and high utility, especially the extended-length EL models. The Explorer, being a high-volume seller, has a strong used market with a wide range of prices depending on trim and mileage, generally retaining value well for its segment. Insurance costs will typically be highest for the QX80 due to its higher initial cost and premium repair parts. The Expedition falls into a moderate category, while the Explorer usually has the lowest insurance premiums among these three. Maintenance costs follow a similar trend; the QX80 will demand premium parts and higher labor rates from Infiniti service centers. Ford parts and labor are generally more affordable for the Explorer and Expedition, though the Expedition's larger components and the EcoBoost engine's specifics might slightly elevate certain service items compared to the Explorer's simpler V6. Resale value is generally good for the Explorer and Expedition, with the QX80 lagging due to its luxury depreciation curve.
Editorial Verdict
Best for families: The 2017 Ford Expedition is the clear winner for larger families needing maximum space for passengers and cargo, especially the EL variant. Its truly adult-friendly third row and superior towing capability make it ideal for family road trips and recreational activities. The Explorer is a strong contender for smaller families seeking a more manageable size and better fuel economy. Best for commuters: The 2017 Ford Explorer, particularly with the 2.3L EcoBoost engine, offers the best balance of fuel efficiency, car-like driving dynamics, and urban maneuverability, making it the most sensible choice for daily commuting. The Infiniti QX80, while comfortable, is less practical for daily urban commutes due to its size and thirst for fuel. Best for enthusiasts: The 2017 Ford Explorer Sport with its 3.5L EcoBoost engine provides the most engaging driving experience with its strong acceleration and more agile handling for an SUV. For enthusiasts whose passion lies in towing, the 2017 Ford Expedition with its 9,200-pound towing capacity is unmatched among these three. Best value overall: The 2017 Ford Explorer offers the best overall value, combining a reasonable purchase price (new or used), respectable fuel economy, sufficient passenger/cargo capacity for many families, and a good balance of features and performance. It strikes a compelling balance for the mass market. If maximum space and towing are absolute necessities and luxury is secondary, the 2017 Ford Expedition offers excellent value for its capability. The Infiniti QX80 offers significant luxury for those who prioritize comfort and premium features, particularly as a used vehicle where its depreciation can make it a more attainable luxury choice.
