The 2017 Ford Explorer Limited represents a significant evolution in the full-size SUV segment, blending robust capability with refined luxury. Under the hood, this specific trim level offered a powertrain designed to balance performance, efficiency, and daily drivability. Understanding the nuances of the 2017 Ford Explorer Limited engine is essential for prospective buyers evaluating its reliability, maintenance costs, and long-term value proposition in the competitive three-row SUV market.
Standard Powerplant Specifications
The primary engine option for the 2017 Ford Explorer Limited was a 3.5-liter EcoBoost V6, a sophisticated piece of engineering that utilized twin turbochargers to force air into the combustion chamber. This configuration allowed the unit to produce an impressive 365 horsepower while delivering a substantial 350 pound-feet of torque. This output provided ample acceleration for highway merging and confident overtaking, while the displacement remained reasonable for the vehicle's size and weight, offering a practical compromise between power and fuel economy.
Technology and Efficiency Features
Ford equipped the 3.5L EcoBoost engine with several advanced technologies to enhance both performance and efficiency. Direct injection precisely delivered fuel into the combustion chamber, optimizing the air-fuel mixture for better combustion. Additionally, the engine featured an auto start-stop system, which temporarily shuts down the engine when the vehicle comes to a complete stop, such as at a traffic light, to reduce idle emissions and conserve fuel. These innovations were crucial in helping the Limited achieve an EPA-estimated 20 MPG in the city and 28 MPG on the highway, figures that were competitive for its class at the time.
Performance and Driving Dynamics
Power delivery from the turbocharged V6 was sent to the wheels via a robust six-speed automatic transmission, which was calibrated to prioritize smooth shifting and responsive acceleration. The engine's low-end torque was particularly effective, minimizing the need for frequent gear changes during normal driving conditions. When paired with the available Intelligent four-wheel-drive system, the 2017 Explorer Limited demonstrated confident traction in various weather conditions, making it a versatile choice for families who encounter diverse driving environments, from dry highways to light winter weather.

Reliability and Maintenance Considerations
While the 3.5L EcoBoost engine was technologically advanced, potential owners should be aware of specific maintenance requirements inherent to turbocharged engines. Regular oil changes with the correct synthetic oil were critical to ensure the turbochargers and bearings remained properly lubricated, as these components operate at high temperatures and speeds. Neglecting the recommended maintenance schedule could lead to premature wear or potential failures, making adherence to factory service intervals a non-negotiable aspect of ownership for longevity.
Common Issues and Solutions
Some owners of the 2017 model year reported issues related to the Mass Air Flow (MAF) sensor and the wiring harness connectors, which could trigger the check engine light or cause rough idling. Ford addressed certain vacuum leak concerns through technical service bulletins, and reputable mechanics often inspect these components during routine service. Staying current with recalls and known technical campaigns is a vital step for any owner to ensure the engine operates at peak efficiency and reliability throughout the vehicle's lifespan.
