Analyzing Ford Explorer Reliability Issues 2017: What Every Owner Needs to Know
When discussing ford explorer reliability issues 2017, the conversation usually starts and ends with the engine bay. While the 2017 model improved on several aspects of the earlier 5th-generation builds, it still carries over a few “ticking time bombs” that require your attention. Being proactive is the difference between a simple fluid change and a total engine replacement.
One of the most significant challenges with this specific year is the complexity of its all-wheel-drive (AWD) system and the cooling requirements of the 3.5L V6 engines. Whether you have the naturally aspirated Ti-VCT or the twin-turbocharged EcoBoost, you need to be aware of how these systems interact with the chassis. Let’s break down the primary areas of concern that define the 2017 reliability landscape.
The Internal Water Pump Disaster
Perhaps the most infamous of all ford explorer reliability issues 2017 is the internal water pump found in the 3.5L Cyclone V6 engines. Unlike most vehicles where the water pump is bolted to the outside of the engine, Ford designed this one to be driven by the timing chain inside the engine block. This design choice has massive implications for long-term reliability.
If the internal seal on the water pump fails, it does not just leak on your driveway. Instead, it leaks coolant directly into the oil pan. When coolant mixes with engine oil, it creates a “chocolate milk” sludge that destroys engine bearings in a matter of miles. This often leads to a complete engine seizure without much warning.
To stay ahead of this, you must regularly check your coolant levels. If you notice the reservoir is low but see no leaks on the ground, check your oil dipstick immediately. If the oil looks milky or frothy, do not start the engine; call a tow truck and prepare for a significant timing chain and water pump service.
AWD Drivetrain and the PTU Overheating
If you drive an AWD model, you need to know about the Power Transfer Unit (PTU). This is the small gearbox responsible for sending power to the rear wheels. In the 2017 Explorer, the PTU is located very close to the exhaust manifold, which subjects the gear oil to extreme heat.
Ford originally claimed the PTU fluid was “lifetime,” but many owners have found that “lifetime” actually means until the warranty expires. The high heat causes the 75W-140 gear oil to break down and turn into a thick, burnt paste. This leads to bearing failure, stripped gears, and a very expensive replacement bill.
Signs of a failing PTU include a “burning oil” smell after highway driving or a high-pitched whining noise from the front-center of the vehicle. To prevent this, we recommend changing the PTU fluid every 30,000 miles. Use a fluid extraction pump to pull the old oil out and replace it with fresh synthetic gear lubricant.
The EcoBoost Factor: Carbon Buildup and Turbo Care
The 2017 Explorer offered the 2.3L four-cylinder and the 3.5L V6 EcoBoost engines. While these provide excellent performance and torque, they are Gasoline Direct Injection (GDI) engines. Because fuel is sprayed directly into the cylinder rather than over the intake valves, the valves never get “washed” by gasoline.
Over time, oil vapors from the PCV system bake onto the hot intake valves, creating carbon deposits. This restriction leads to rough idling, reduced fuel economy, and a noticeable loss of power under acceleration. It is a common occurrence in the 2017 model year as these vehicles cross the 80,000-mile mark.
To combat this, many DIYers install a catch can to trap oil vapors before they reach the intake. Additionally, using a dedicated GDI intake valve cleaner spray every 10,000 miles can help dissolve soft deposits. If the buildup is severe, you may need a professional “walnut blasting” service to restore airflow.
Turbocharger Longevity and Oil Coking
Turbochargers rely on a constant supply of clean oil for both lubrication and cooling. In the 3.5L EcoBoost, the oil feed lines are susceptible to clogging if oil changes are neglected. If the oil “cooks” inside the lines, the turbo bearings will starve and fail, leading to smoke from the exhaust and a massive loss of boost.
Always use a high-quality full synthetic oil and a motorcraft filter. We suggest changing your oil every 5,000 miles regardless of what the “Oil Life Monitor” says. This is especially true if you use your Explorer for towing or heavy off-roading, as these activities put more thermal stress on the turbochargers.
Suspension and Steering: The Toe Link Concern
The 2017 Ford Explorer has been the subject of several high-profile recalls regarding the rear suspension. Specifically, the rear suspension toe links are prone to fracturing. If a toe link snaps while you are driving, you will lose control of the steering in the rear, which can lead to a crash.
This is one of the most critical ford explorer reliability issues 2017 because it involves occupant safety. Ford has issued multiple recalls for this, but even “repaired” vehicles have sometimes seen subsequent failures. If you hear a clunking noise from the rear over bumps, inspect your toe links immediately.
When inspecting the suspension, look for signs of rust or stress cracks near the bushings. If you frequently drive on salted winter roads or take your Explorer off-road, these components are under even higher stress. Ensure your local dealership has performed all relevant safety recalls tied to your VIN.
Electric Power Assisted Steering (EPAS) Failures
The steering in the 2017 model is electric rather than hydraulic. While this improves fuel efficiency, the steering rack itself can suffer from internal sensor failures. Owners have reported the steering suddenly becoming very heavy or losing power assistance entirely while turning.
In some cases, this is caused by a faulty steering angle sensor or a corroded electrical connector. Before replacing the entire rack, which is quite costly, check the grounding wires and the battery health. Low voltage can cause the EPAS system to throw error codes and shut down as a protective measure.
Electronic Gremlins: Sync 3 and Sensor Failures
The 2017 model year saw the introduction of Sync 3, which was a massive improvement over the previous MyFord Touch system. However, it is not immune to glitches. Common issues include the screen freezing, Bluetooth disconnecting, or the GPS losing its position in the middle of a trip.
Most Sync issues can be resolved with a software update via USB or Wi-Fi. If the screen remains black, you may need to perform a “master reset” through the settings menu. In rarer cases, the APIM (Accessory Protocol Interface Module) hardware fails and requires replacement to restore functionality.
Blind Spot Monitoring and Backup Cameras
The safety sensors on the 2017 Explorer are often exposed to the elements. The blind spot monitors (BLIS) are located behind the rear bumper cover. Mud, road salt, and moisture can seep into the connectors, causing “Blind Spot System Fault” messages on your dashboard.
Similarly, the backup camera is known to get foggy or display a “Camera Unavailable” message. Often, this is just a loose connection inside the rear liftgate. A quick DIY fix involves removing the interior trim panel and ensuring the wiring harness is seated tightly and free of corrosion.
Body and Exterior: The Aluminum Hood Bubble
While not a mechanical failure, many owners include paint issues in their list of ford explorer reliability issues 2017. The hood of the 2017 Explorer is made of aluminum. Due to a contamination issue during the manufacturing process, the paint can develop bubbles along the leading edge of the hood.
This is caused by iron particles trapped under the paint reacting with the aluminum, leading to corrosion. Once the bubbling starts, the only permanent fix is to strip the hood to bare metal and repaint it, or replace the hood entirely. If your vehicle is still under the corrosion warranty, check with your dealer to see if they will cover the repair.
Door Latches and Weatherstripping
Keep an eye on your door latches and the rubber weatherstripping. Some owners have reported doors that “bounce” back when trying to close them in freezing temperatures. This is usually due to moisture getting into the latch mechanism and freezing. Applying a silicone-based lubricant to the latches can prevent this annoying winter problem.
Maintenance Checklist to Avoid Common Pitfalls
To mitigate the ford explorer reliability issues 2017 we have discussed, a strict maintenance schedule is your best defense. If you plan on keeping your Explorer for the long haul, do not follow the “minimum” requirements found in the owner’s manual. Follow these pro-active steps instead:
- Oil Changes: Every 5,000 miles using full synthetic 5W-30 (or 5W-20 for Ti-VCT).
- PTU Fluid: Every 30,000 miles to prevent “cooking” the gear oil.
- Coolant Flush: Every 50,000 miles to protect the internal water pump seals.
- Transmission Fluid: Every 60,000 miles (drain and fill, do not flush).
- Throttle Body Cleaning: Every 30,000 miles to maintain a smooth idle.
Using an OBD-II scanner is also a great habit for the 2017 Explorer owner. Many of these issues, like PTU overheating or carbon buildup, will trigger “pending” codes before they turn on the dashboard light. Catching a code for a “misfire” or “low coolant flow” early can save you thousands of dollars in repairs.
Frequently Asked Questions About ford explorer reliability issues 2017
Is the 2017 Ford Explorer a reliable used car?
Yes, provided it has been well-maintained. The key is checking the service history for PTU fluid changes and ensuring the rear toe link recalls have been completed. If the engine has over 100,000 miles, ask if the water pump has already been replaced, as that is a major looming expense.
How much does it cost to fix the 2017 Explorer water pump?
Because the water pump is internal, the labor is intensive. It typically costs between $1,500 and $2,500 because the front of the engine must be disassembled. Many mechanics recommend replacing the timing chain and tensioners at the same time since they are already exposed.
Does the 2017 Ford Explorer have transmission problems?
The 6F55 and 6F50 6-speed transmissions are generally robust, but they can suffer from harsh shifting if the fluid is never changed. If you experience “shuddering” at highway speeds, it may be a torque converter issue or simply old fluid that has lost its viscosity.
What are the signs of a failing PTU in a 2017 Explorer?
The most common signs are a burning smell (like burnt toast or oil), a puddle of thick black fluid under the middle of the car, or a growling noise that changes with vehicle speed. If you hear “clicking” during tight turns, the PTU gears may already be damaged.
Should I buy a 2017 Explorer with the EcoBoost engine?
The EcoBoost offers great power, but it requires stricter maintenance. If you are a DIYer who doesn’t mind changing oil frequently and cleaning intake valves, it is a great choice. If you want the simplest, most reliable engine, the naturally aspirated 3.5L V6 is slightly easier to maintain, though it still has the internal water pump risk.
