The 2017 Ford Explorer represents a significant moment for the brand, sitting at the intersection of its aging platform and the introduction of a new generation. While it offered the capability and space families needed, potential buyers investigating 2017 Ford Explorer reliability issues often found a mixed picture in owner reports and mechanic feedback. This specific model year sat right before a major redesign, meaning it carried over the core mechanicals from the previous generation while using newer electronics and materials. Understanding the nuances of these common complaints helps anyone weigh the purchase price against potential long-term ownership costs.
Common Mechanical Problems Reported
Delving into 2017 Ford Explorer reliability issues reveals a pattern centered around the aging 3.5-liter EcoBoost engine and the six-speed automatic transmission. Owners frequently cite timing chain tensioners as a primary concern, with some units failing prematurely and causing unusual rattling noises, particularly during cold starts. This issue, if left unaddressed, can lead to more severe internal damage, making it one of the more critical reliability flags for this model year. The complexity of the EcoBoost system, while providing strong power, introduces more points of potential failure compared to the simpler naturally aspirated engines of the past.
Transmission and Shifting Concerns
Alongside the engine, the 6F55 six-speed automatic transmission produced its own set of headaches for some drivers. Reports of harsh shifting, particularly between first and second gears, are common in forum discussions and technical service bulletins. In more severe instances, the transmission control module could develop faults, leading to erratic behavior or even limp mode activation. These transmission problems directly impact the driving experience and are a major factor in the overall assessment of 2017 Ford Explorer reliability.
Electrical and Infotainment Issues
As with many vehicles from this era, electrical gremlins pose a significant challenge to 2017 Ford Explorer reliability. The central touchscreen infotainment system, while advanced for its time, was prone to freezing, random reboots, and unresponsive touch inputs. More troubling were issues with the vehicle's integrated sensors, such as the rear parking camera suddenly failing or the blind-spot monitoring system providing erroneous alerts. These electronic faults not only cause frustration but can also create safety concerns if critical driver-assist features malfunction.
Software and Sensor Malfunctions
The SYNC 3 software required numerous updates throughout the production run, and 2017 models often shipped with early versions that were buggy and unstable. Owners reported glitches in everything from Bluetooth connectivity to the adaptive cruise control system. Furthermore, the numerous sensors scattered across the vehicle—responsible for everything from tire pressure monitoring to automatic emergency braking—were known to fail or provide false warnings. Diagnosing these electrical gremlins can be time-consuming and expensive, adding to the long-term cost of ownership.
Other Notable Reliability Factors
Beyond the major mechanical and electronic components, there are additional wear items and design quirks that affect the 2017 Ford Explorer reliability. The auxiliary drive belt, also known as the serpentine belt, tends to wear faster than expected on some units, requiring periodic replacement to avoid a sudden failure that would leave the vehicle stranded. Premature wear on front brake pads and rotors is also a commonly reported issue, likely due to the vehicle's weight and aggressive initial brake calibration.
Maintenance and Component Wear
The timing belt cover itself, and the seals surrounding the valve cover, are potential leak points as the high-mileage vehicle ages. Coolant leaks from these areas can lead to overheating and further engine stress if not caught early. While these are generally considered normal wear and tear, the frequency at which they appear on this specific model year contributes to the overall reliability narrative. Potential buyers should factor in the cost of addressing these items when evaluating a used 2017 Explorer.
