High-end luxury and rugged capability used to be two distinct categories until vehicles like the 2017 Ford Explorer Platinum bridged the gap. Even as we move through 2026, this specific model year stands out as a high-water mark for Ford’s fifth-generation Explorer. It was the year Ford fully integrated the SYNC 3 system, refined the twin-turbo power delivery, and pushed the interior materials into a realm previously reserved for European luxury brands. For anyone scanning the pre-owned market for a three-row SUV that doesn't feel like a compromise, the Platinum trim offers a compelling argument through its sheer density of features and mechanical muscle.

The Mechanical Heart: 3.5L EcoBoost Dominance

At the center of the 2017 Ford Explorer Platinum experience is the 3.5-liter EcoBoost V6 engine. This isn't the standard naturally aspirated mill found in the base trims; it is the same twin-turbocharged powerhouse that Ford utilized in the Police Interceptor Utility and the Taurus SHO. Delivering 365 horsepower and 350 lb-ft of torque, this engine transforms a heavy, 4,900-pound SUV into a surprisingly agile performer.

In real-world driving scenarios, the power delivery is linear but assertive. The turbo lag is minimal, thanks to the way Ford tuned the six-speed SelectShift automatic transmission to stay within the meat of the power band. When merging onto highways or overtaking at speed, the Platinum trim provides a level of confidence that many modern four-cylinder turbocharged SUVs struggle to replicate. However, this performance comes with a trade-off in efficiency. Owners typically see around 16 mpg in the city and 22 mpg on the highway. In an era where hybrid alternatives are becoming the norm, the 2017 Platinum remains a choice for those who prioritize towing capacity (up to 5,000 lbs) and raw acceleration over fuel economy.

Nirvana Leather and the Premium Cabin Experience

Stepping inside the Platinum trim reveals where the extra MSRP went back in 2017. While lower trims relied heavily on hard plastics and synthetic materials, the Platinum introduced "Nirvana" leather. This grade of leather is softer, more breathable, and covers not just the seats but also the instrument panel, console armrests, and door bolsters. The quilted stitching and micro-perforation give it a distinct visual identity that has aged remarkably well in terms of style.

One of the standout features that remains a luxury staple even today is the inclusion of multi-contour front seats with Active Motion. Essentially, these are massaging seats that help reduce driver fatigue on long hauls. Combined with heating and ventilation, the front row of the 2017 Platinum is arguably more comfortable than many entry-level luxury crossovers released this year. The real wood accents and brushed aluminum trim pieces are not just overlays; they are authentic materials that provide a tactile sense of quality often missing from modern "piano black" plastic interiors.

Technology: The SYNC 3 Advantage in 2026

Technology in cars usually ages like milk, but 2017 was a pivotal year for Ford. This was the first full production year where the problematic MyFord Touch system was completely replaced by SYNC 3. For a buyer in 2026, this is the single most important tech consideration. SYNC 3 was designed to be faster, more intuitive, and most importantly, it supports Apple CarPlay and Android Auto.

Even a decade later, as long as the hardware is functioning, you can plug in a modern smartphone and have access to the latest maps, music, and voice commands. The 8.0-inch touchscreen is responsive, and the physical buttons for climate control and volume—which many newer cars have annoyingly moved to touch menus—remain easy to operate without taking your eyes off the road. The 500-watt Sony premium audio system with Clear Phase and Live Acoustics technology provides a rich soundstage that fills the large cabin, making it an excellent mobile concert hall for road trips.

Seating Logic and Cargo Versatility

Flexibility is the core mission of the Explorer. In the Platinum trim, you often find the second-row bucket seats with a center console, reducing the total capacity to six passengers but significantly increasing the comfort and accessibility of the third row. The PowerFold third-row seats are a highlight of the utility package; with the press of a button, the rear seats fold flat into the floor or flip into a "tailgate" position for outdoor events.

Cargo space behind the third row is a respectable 21 cubic feet, which is enough for a grocery run or a few small suitcases. When both rear rows are folded, that space expands to a massive 81 cubic feet. The floor is nearly flat, though the second-row console (if equipped) can create a slight bump in the middle. The hands-free, foot-activated power liftgate—a novelty in 2017—has become a standard expectation now, and on the Platinum, it works reliably to assist when your hands are full.

Driving Dynamics: The "Big Car" Feel

The 2017 Ford Explorer Platinum utilizes a car-based unibody platform (the D4 platform), which gives it better road manners than a traditional body-on-frame SUV like the Expedition. However, it still "drives big." The hood is long and high, and the thick A-pillars can create blind spots at intersections. Ford mitigated this by including a 180-degree front camera and a suite of sensors, but the driver always feels the mass of the vehicle.

The suspension tuning on the Platinum is biased toward comfort. It soaks up expansion joints and potholes with poise, aided by the 20-inch bright-machined wheels with dark painted pockets. While it doesn't have the stiff, corner-carving ambitions of the Explorer Sport, it remains composed during spirited driving. The Intelligent 4WD system with Terrain Management allows the driver to toggle between Normal, Mud/Ruts, Sand, and Grass/Gravel/Snow modes. While not a rock crawler, it is more than capable of handling deep snow and light off-road trails, providing peace of mind for those living in four-season climates.

Safety Suite: Advanced for its Time

In terms of safety, the 2017 Platinum was ahead of the curve. It comes standard with a comprehensive array of driver-assist technologies that many manufacturers were still charging extra for at the time. This includes:

  • Adaptive Cruise Control and Forward Collision Warning: Uses radar to maintain distance from the car ahead.
  • Blind Spot Information System (BLIS): Essential for a vehicle of this size, notifying the driver of vehicles in the adjacent lanes.
  • Lane-Keeping System: Vibrates the steering wheel if you drift and can apply steering torque to help guide you back.
  • Enhanced Active Park Assist: This system can actually steer the vehicle into a parallel or perpendicular parking spot while the driver controls the gear shifter and pedals.

One unique feature found in this era of Explorer is the inflatable rear outboard safety belts. These belts contain a small airbag that deploys upon impact to distribute crash forces over a wider area of the passenger’s torso, particularly beneficial for children or elderly passengers in the second row.

The 2026 Perspective: Long-Term Reliability and Maintenance

When buying or maintaining a 2017 Ford Explorer Platinum today, there are several mechanical areas that require specific attention. While the 3.5L EcoBoost is a robust engine, it is not without its quirks.

The Water Pump Issue

One of the most discussed points in the Explorer community is the internal water pump. Unlike most engines where the water pump is driven by the serpentine belt on the outside, the 3.5L Duratec/EcoBoost family has the water pump driven by the internal timing chain. If the pump seal fails, coolant can leak directly into the oil pan, leading to potential engine failure if not caught immediately. Prospective buyers should check for any signs of milky residue on the oil dipstick or a disappearing coolant level without visible external leaks. Replacing this pump is labor-intensive (often 10+ hours), so ensuring it has been serviced or budgeting for it is wise.

Power Transfer Unit (PTU)

The PTU is responsible for sending power to the rear wheels in the 4WD system. In early iterations, the fluid in the PTU could break down due to heat because it was located close to the exhaust. By 2017, Ford had improved this, but it is still recommended to change the PTU fluid every 30,000 to 50,000 miles to prevent the common "propeller shaft" or gear failure. If you hear a high-pitched whine from the front end or smell burning gear oil after a highway drive, the PTU may be struggling.

Carbon Buildup

As a direct-injection engine, the EcoBoost can suffer from carbon buildup on the intake valves over time, as there is no fuel washing over them to keep them clean. This can result in a rough idle or a slight loss of power. High-quality fuel and occasional professional intake cleaning can keep this in check.

Why the Platinum specifically?

You might wonder if the Limited or Sport trims offer better value. The Sport trim has the same engine but a much stiffer suspension and a darker, more aggressive interior. The Limited trim offers many of the same features but lacks the upgraded leather, the Sony sound system enhancements, and the specific aesthetic of the Platinum.

The Platinum was designed to be the "no-compromises" Explorer. It combined the speed of the Sport with a luxury level that exceeded the Limited. For a used buyer today, the price gap between a Limited and a Platinum has likely narrowed to a few thousand dollars, making the jump to the Platinum's superior interior materials a logical choice for those who appreciate the finer details.

Ownership Costs and Market Value

As of April 2026, a well-maintained 2017 Ford Explorer Platinum with 80,000 to 100,000 miles typically sits in a very attractive price bracket. It has depreciated enough to be affordable for families but retains enough utility and style to not feel like an "old car."

Maintenance costs are generally in line with other domestic SUVs. Tires for the 20-inch wheels can be expensive, and the complex electronics mean that if a massage seat motor or an adaptive cruise sensor fails, the repair won't be cheap. However, because so many Explorers were sold, parts availability is excellent, and most independent mechanics are very familiar with the platform.

Final Verdict

The 2017 Ford Explorer Platinum represents a specific era where Ford was determined to prove they could build a world-class luxury SUV. While the fuel economy might feel dated by 2026 standards, the combination of 365 turbocharged horsepower, genuine Nirvana leather, and a still-relevant infotainment system makes it a standout choice. It’s a vehicle that handles the school run, the cross-country road trip, and the winter blizzard with equal aplomb. If you can verify the maintenance history—specifically regarding the water pump and PTU—it remains one of the most versatile and comfortable ways to transport a family without the premium price tag of a brand-new luxury vehicle.
