Many owners have reported specific 2017 ford explorer common problems that can range from simple sensor fixes to catastrophic engine damage. In this guide, we will break down exactly what to look for, how to diagnose issues early, and when you should grab your tools or call a professional.
By the end of this article, you will have a clear roadmap for maintaining your Explorer’s health. We will cover the critical engine components, suspension recalls, and those annoying electronic glitches that pop up over time.
The Internal Water Pump: A Critical 3.5L V6 Vulnerability
If your Explorer is equipped with the 3.5L Cyclone V6 engine, the water pump is your primary concern. Unlike most vehicles where the pump is external, Ford designed this one to be driven by the timing chain inside the engine block.
When this pump fails, it often leaks coolant directly into the oil pan. This creates a “milky” oil mixture that destroys engine bearings in a matter of miles. If you see a low coolant light without a visible puddle on the ground, stop driving immediately.
Check your oil dipstick frequently for any signs of discoloration or a frothy texture. Replacing this pump is a massive job that requires specialized timing tools and significant teardown, often costing upwards of $2,000 at a shop.
Signs of Water Pump Failure
- Unexplained loss of coolant in the reservoir.
- A faint smell of sweet antifreeze inside the cabin or under the hood.
- Engine oil that looks like chocolate milk on the dipstick.
- Brief rattling noises from the front of the engine during a cold start.
2017 ford explorer common problems: Transmission and Drivetrain
The 6-speed automatic transmission in the 2017 Explorer is generally robust, but it is not without its faults. Many drivers report harsh shifting or “hunting” for gears, especially when the vehicle is under a heavy load or climbing steep grades.
One of the most overlooked 2017 ford explorer common problems involves the Power Transfer Unit (PTU) on All-Wheel Drive (AWD) models. The PTU sits near the exhaust, which causes the lubricant inside to “cook” and turn into a thick sludge.
Ford originally claimed the PTU fluid was “lifetime,” but experienced mechanics suggest changing it every 30,000 miles. If you hear a high-pitched whining noise from the center of the vehicle, your PTU might be starving for fresh gear oil.
Maintaining the Drivetrain
- Drain and fill the transmission fluid every 50,000 miles using Mercon LV fluid.
- Inspect the PTU for leaks or “venting” fluid, which looks like dark gunk on the casing.
- Use an OBD-II scanner to check for transmission solenoid codes if you experience slipping.
Suspension Woes: The Rear Toe Link Issue
Does your Explorer feel “loose” or “darty” when hitting bumps on the highway? The 2017 model has been the subject of several recalls regarding the rear suspension toe links, which can fracture under stress.
A broken toe link significantly increases the risk of a crash because it allows the rear wheel to steer independently. This is especially dangerous for off-roaders who frequent washboard roads or rocky trails where vibration is constant.
To check this yourself, safely jack up the rear of the vehicle and grab the tire at the 3 o’clock and 9 o’clock positions. If there is any lateral play or clicking sounds, your toe links or bushings likely need immediate replacement.
Suspension Warning Signs
- A loud “clunking” or “banging” noise from the rear over speed bumps.
- Uneven tire wear on the inside edges of the rear wheels.
- The steering wheel feels off-center even when driving straight.
- The stability control light flashing intermittently during normal turns.
Cabin Air Quality and the Exhaust Smell Mystery
One of the more frustrating 2017 ford explorer common problems involves a persistent smell of exhaust fumes inside the cabin. This typically happens during hard acceleration or when the air conditioning is in “recirculation” mode.
The issue often stems from unsealed body seams behind the rear bumper or faulty auxiliary AC drains. While Ford released several Technical Service Bulletins (TSBs) to address this, some owners still struggle to find a permanent fix.
If you smell fumes, start by inspecting the rear liftgate seal for gaps. You can also apply a silicone sealant to the body “weep holes” located behind the rear quarter panels to prevent gases from entering the interior.
DIY Fixes for Exhaust Smells
- Ensure the exhaust tips extend past the rear bumper valance.
- Replace the cabin air filter with a high-quality carbon-activated version.
- Check the rear air conditioning drain tube for blockages or cracks.
- Inspect the exhaust manifold for hairline cracks, especially on EcoBoost engines.
Exterior and Body: The Aluminum Hood Corrosion
While mechanical issues are the priority, the 2017 Explorer also suffers from a common cosmetic defect: paint bubbling on the hood. This occurs because the hood is made of aluminum, and iron particles can get trapped under the paint during manufacturing.
Once oxidation starts, the paint begins to lift, usually along the leading edge. This is a chemical reaction that cannot be fixed by simply touching up the paint; it requires a complete strip and specialized primer.
If you are buying a used 2017 model, look closely at the front edge of the hood for small blisters. While this doesn’t affect safety, it can significantly hurt the resale value of your vehicle over time.
EcoBoost Engine Performance and Carbon Buildup
The 2.3L and 3.5L EcoBoost engines offer impressive power, but they are Direct Injection (DI) engines. Because fuel is sprayed directly into the cylinder, it never washes over the intake valves, leading to carbon deposits.
Over time, this carbon buildup causes “stumbling” at idle and a loss of fuel economy. To prevent this, many DIY mechanics install an oil catch can to intercept oil vapors before they reach the intake manifold.
Additionally, the turbochargers on these engines rely on clean oil for cooling. If you skip oil changes, the turbo bearings can coke up, leading to a very expensive replacement job.
Pro-Tips for EcoBoost Longevity
- Use only high-quality full synthetic oil to reduce vapor deposits.
- Perform an intake valve cleaning service every 40,000 miles.
- Always let the engine idle for 30 seconds after a long drive to cool the turbos.
- Check the spark plug gaps every 30,000 miles, as EcoBoost engines are hard on plugs.
Frequently Asked Questions About 2017 ford explorer common problems
Is the 2017 Ford Explorer a reliable SUV?
Generally, yes, but its reliability depends heavily on the engine choice and maintenance history. The 3.5L non-turbo V6 is very durable aside from the internal water pump, while the EcoBoost models require more frequent sensor and carbon maintenance.
How much does it cost to fix the water pump?
Because the water pump is located behind the timing cover, the labor is intensive. Expect to pay between $1,500 and $2,500 at a dealership, as many mechanics recommend replacing the timing chain and tensioners at the same time.
What should I do if I smell exhaust in my Explorer?
First, check for any open recalls related to the exhaust system. If no recalls apply, inspect the rear liftgate seal and the body vents located behind the rear bumper. Installing a turn-down exhaust tip can also help move fumes away from the liftgate area.
Why is my 2017 Explorer shifting hard?
Hard shifting is often caused by old transmission fluid or a failing shift solenoid. Start by checking the fluid level and color. If the fluid is dark or smells burnt, a professional flush and a software update for the Transmission Control Module (TCM) may be necessary.
Are the suspension recalls free to fix?
Yes, if your vehicle is covered under an official safety recall for the rear toe links, a Ford dealership must perform the repair at no cost to you. Always run your VIN through the NHTSA website to check for outstanding recalls.
Final Thoughts for the Savvy Owner
Owning a 2017 Ford Explorer is a rewarding experience if you stay ahead of the maintenance curve. While the list of 2017 ford explorer common problems might seem daunting, most are manageable with regular inspections and a proactive approach to fluid changes.
Always prioritize the “big three”: the water pump, the PTU fluid, and the rear suspension links. Addressing these areas early ensures that your SUV remains a dependable partner for all your road trips and daily commutes.
Keep your tools ready, listen for new noises, and don’t ignore those small leaks. With a little bit of grease and attention, your Explorer will be ready for the many miles of adventure ahead. Stay safe and stay comfortable!
