Owners of the 2017 Ford Explorer Sport often praise its commanding presence and versatile capability, yet even this robust SUV is not immune to specific mechanical gremlins. While the model year addressed some drivability concerns found in earlier generations, it introduced its own set of challenges that demand attention. Understanding the most common issues helps owners maintain safety, prevent costly repairs, and ensure the vehicle delivers the confident ride it promises.
Electrical System Malfunctions
The 2017 Explorer Sport, like many vehicles of its era, can suffer from perplexing electrical gremlins that appear without warning. These issues often manifest as intermittent warning lights, malfunctioning infotainment systems, or unexpected power loss while driving. The complexity of the wiring harness and multiple control modules creates an environment where corrosion or a simple faulty connection can trigger a cascade of electronic failures. Diagnosing these problems requires patience and often a professional scan tool to read the specific trouble codes stored in the vehicle's computer.
Transmission Overheating and Failure
A critical concern for the 2017 Ford Explorer Sport is the potential for transmission overheating, particularly when towing or navigating stop-and-go traffic in hot climates. The 10-speed automatic transmission, while advanced, can be strained under heavy loads, leading to degraded fluid performance and increased wear. If the transmission control module detects excessive heat, it may initiate a limp mode that restricts performance to prevent catastrophic damage. Ignoring the initial signs of overheating, such as slipping gears or unusual burning smells, can result in a complete transmission failure and a very expensive repair bill.
Identifying Early Warning Signs
Transmission fluid that appears dark brown or has a burnt odor.
Delayed engagement when shifting from Park to Drive.
Unusual whining or clunking sounds during acceleration.
Suspension and Steering Wear
Drivers of the 2017 Explorer Sport will eventually encounter the physical toll that miles take on the suspension components. The front struts and associated bushings are subjected to constant stress, leading to a noticeable decline in ride comfort and handling precision. Worn control arm bushings or a failing stabilizer bar link can introduce clunking noises over uneven roads and cause the vehicle to feel loose during cornering. Regular inspection of these components is essential for maintaining the sporty handling that the Explorer Sport is known for.
Engine Oil Consumption and Dilution
Some 2017 models equipped with the 2.3L EcoBoost engine may experience higher than normal oil consumption, a issue that can lead to internal engine damage if left unchecked. A related problem involves fuel dilution, where unburned fuel mixes with the engine oil, thinning it and reducing its lubricating properties. This creates a vicious cycle where the engine works harder, generating more heat and exacerbating the problem. Monitoring the oil level between changes and addressing any sudden drops immediately can prevent severe engine wear.
Infotainment and Software Glitches
The Sync 3 infotainment system in the 2017 Explorer Sport is generally reliable but not without its quirks. Owners might experience freezing screens, unresponsive touchscreens, or Bluetooth connectivity issues that disrupt the driving experience. Software updates released by Ford have addressed many of these bugs, but ensuring the system is current requires a visit to the dealership or a careful follow-through of update instructions. These glitches, while not dangerous, can be incredibly frustrating on long road trips.
