2017 Ford Explorer Issues – Diagnostic Guide And DIY Fixes
The 2017 Ford Explorer is a robust mid-sized SUV, but it is prone to specific mechanical failures involving the internal water pump, rear suspension toe links, and exhaust fume intrusion. Identifying these common 2017 ford explorer issues early can save you thousands in labor costs and ensure your vehicle remains safe for family road trips or off-road excursions.
You rely on your Explorer to handle everything from the daily school run to weekend camping trips in the backcountry. It is frustrating when a dependable rig starts making strange noises or exhibiting “check engine” lights that seem to come out of nowhere.
I have spent years under the hoods of Ford trucks and SUVs, and I promise to show you exactly what to look for and how to handle these repairs. This guide previews the most critical 2017 ford explorer issues, offering practical advice for the weekend mechanic and the safety-conscious owner.
Whether you are dealing with a shifting hesitation or a mysterious smell in the cabin, we have the diagnostic steps you need to take. Let’s dive into the technical details and get your Explorer back into peak operating condition.
The Infamous Internal Water Pump (3.5L V6 Engine)
If you own the 3.5L Ti-VCT Cyclone V6 engine, you need to be aware of one of the most significant mechanical vulnerabilities in this model year. Unlike most vehicles where the water pump is driven by the accessory belt, this pump is driven by the timing chain inside the engine.
When this pump fails, it doesn’t just leak on your driveway; it often leaks internally into the engine oil pan. This creates a “milky” oil mixture that can destroy your engine bearings in a matter of miles if not caught immediately.
To check for this, pull your oil dipstick every time you fuel up. If the oil looks like a chocolate milkshake or if your coolant level is dropping with no visible external leaks, stop driving immediately and call a flatbed tow truck.
Signs of a Failing Internal Pump
- A low coolant warning on the dash without any puddles under the car.
- A faint smell of burning antifreeze coming from the front grill.
- A small trickle of coolant coming from the “weep hole” located behind the alternator.
The DIY Reality Check
Replacing this pump is a massive undertaking for a DIYer. It requires removing the front timing cover, which involves significant engine disassembly. If you attempt this, you will need a timing chain locking tool and a high-quality torque wrench.
Most professional shops charge between $1,500 and $2,500 for this job because of the labor involved. If you are a seasoned mechanic, it is a rewarding 12-hour project, but for most, this is a job for a trusted local technician.
2017 ford explorer issues: Suspension and the Rear Toe Link Recall
One of the most widely reported 2017 ford explorer issues involves the rear suspension, specifically the rear toe links. These components are responsible for keeping your rear wheels aligned and preventing them from “steering” themselves while you drive.
Ford has issued multiple recalls for these links because they are prone to snapping due to stress and corrosion. If a toe link breaks while you are traveling at highway speeds, it can cause a sudden loss of steering control, which is a major safety hazard.
For off-roaders, this issue is even more critical. The added stress of uneven trails and heavy loads can accelerate the fatigue in these parts. If you hear a loud “clunk” or “pop” from the rear of the vehicle over bumps, inspect your suspension immediately.
How to Inspect Your Toe Links
- Jack up the rear of the vehicle and secure it on heavy-duty jack stands.
- Grasp the rear tire at the 3 o’clock and 9 o’clock positions.
- Shake the wheel firmly; if there is any “play” or clicking, the toe link or bushing is likely shot.
- Visually inspect the links for cracks or excessive rust near the mounting points.
Dealing with Recalls
Before you spend money on aftermarket parts, call your local Ford dealer with your VIN. Many 2017 models are covered under Safety Recall 19S17 or subsequent updates. If your vehicle qualifies, the dealership will replace these parts for free.
Exhaust Odors and Carbon Monoxide Safety
A frequent complaint among 2017 Explorer owners is the smell of exhaust fumes inside the cabin, particularly during heavy acceleration. This isn’t just an annoyance; it is a safety concern regarding carbon monoxide (CO) exposure.
The issue often stems from unsealed body seams at the rear of the vehicle or poorly designed exhaust tips that allow fumes to get sucked back into the cabin through the air extractors. Ford released a field service action to address this by recalibrating the HVAC system and sealing the rear chassis.
If you frequently travel with children or pets, I highly recommend buying a portable digital carbon monoxide detector to keep in the center console. This provides peace of mind while you work on a permanent fix.
DIY Troubleshooting for Cabin Smells
- Check the rear liftgate seal for any gaps or tears that might let air in.
- Inspect the “auxiliary” air conditioning lines if you have rear air, as leaks here can sometimes mimic exhaust smells.
- Look for soot marks around the exhaust manifold; cracked manifolds are a common source of fumes in the engine bay.
If you find a cracked manifold, you will likely notice a “ticking” sound when the engine is cold that disappears as the metal expands. Replacing the manifold on the EcoBoost engines is tight but doable for a patient DIYer with a good set of swivel sockets.
Transmission Shudder and Shifting Hesitation
The 6-speed 6F50 and 6F55 transmissions used in the 2017 Explorer are generally reliable, but they are known for developing a “shudder” or “hunting” for gears. This often feels like you are driving over rumble strips when the car is in a higher gear at low RPMs.
The primary culprit is often the torque converter clutch or degraded transmission fluid. Ford claims the fluid is “lifetime,” but as a mechanic, I tell my clients that “lifetime” usually means the lifetime of the warranty.
For those who tow trailers or go off-roading, the transmission works much harder. Heat is the number one killer of automatic transmissions, so keeping your fluid fresh is the best preventative maintenance you can perform.
Transmission Maintenance Tips
Perform a “drain and fill” every 30,000 to 50,000 miles rather than a high-pressure flush. A flush can sometimes dislodge debris that clogs the small valves inside the transmission control body.
Always use the specific Mercon LV fluid required for this transmission. Using a “universal” fluid can lead to harsh shifting and long-term damage to the internal seals.
Exterior Body Problems: Aluminum Hood Corrosion
Have you noticed small bubbles forming under the paint at the very front edge of your hood? This is a common issue with the 2017 Explorer’s aluminum hood. It is caused by filiform corrosion, which happens when iron particles or contaminants get trapped under the paint during manufacturing.
Unlike steel, aluminum doesn’t “rust” in the traditional sense, but it does oxidize, causing the paint to lift and flake away. This is primarily a cosmetic issue, but it can significantly hurt the resale value of your vehicle.
If your vehicle is still under the 5-year/unlimited mileage corrosion warranty, the dealership may replace or repaint the hood. If you are out of warranty, you can slow the process by keeping the area clean and applying a high-quality automotive wax or ceramic coating.
DIY Hood Repair
Repairing aluminum corrosion is tricky because you must remove every trace of the oxidation before priming. If you just sand it and spray it, the bubbles will return within months. Use a zinc-chromate primer specifically designed for aluminum for the best adhesion.
Electrical Glitches and Sync 3 Troubleshooting
The 2017 model year features the Sync 3 infotainment system. While a massive upgrade over the previous “MyFord Touch,” it is not without its electronic gremlins. Common issues include the screen freezing, the backup camera staying on while driving, or Bluetooth failing to connect.
Before you assume the hardware is broken, try a “Master Reset” through the settings menu. If that doesn’t work, you can perform a “Soft Reset” by holding the Power button and the Seek Up button simultaneously for about 10 seconds.
Another common electrical failure is the backup camera itself. The wiring harness in the liftgate can become pinched or the camera lens can leak, causing a “Camera Unavailable” message on the screen.
Step-by-Step Backup Camera Check
- Open the liftgate and inspect the rubber boot where the wires pass from the body to the gate.
- Check the fuse box under the dashboard for any blown fuses related to the “Park Aid” or “Display.”
- If you need to replace the camera, you will have to remove the interior plastic trim of the liftgate to access the mounting bolts.
Essential Tools for Explorer Maintenance
To tackle these 2017 ford explorer issues effectively, you need more than just a basic screwdriver set. Investing in a few specialized tools will make your DIY life much easier and safer.
A high-quality OBD-II Scan Tool is mandatory. Modern Fords use a communication protocol called CAN bus, and a scanner that can read “Live Data” will help you diagnose misfires or transmission slips before they turn into major repairs.
For suspension work, a breaker bar and a set of metric deep-well sockets (specifically 18mm and 19mm) are essential. Ford uses high-torque fasteners that are often seized by road salt and grime.
Recommended Tool List
- Digital Multimeter: For testing battery voltage and alternator output.
- Coolant Pressure Tester: To find those “hidden” leaks around the water pump.
- Trim Removal Tools: Plastic pry bars to remove interior panels without scratching them.
- Torque Wrench: Critical for lug nuts (100 lb-ft) and suspension components.
Frequently Asked Questions About 2017 Ford Explorer Issues
Is the 2017 Ford Explorer a reliable car?
Overall, yes. While it has specific “sore spots” like the water pump and toe links, many owners reach 200,000 miles with regular maintenance. The key is being proactive rather than reactive with repairs.
How much does it cost to fix the exhaust smell issue?
If it is covered under Ford’s service action, it may be free. If you are paying out of pocket for a mechanic to seal the chassis and replace the air extractors, expect to pay between $300 and $600.
Does the 2017 Ford Explorer have transmission problems?
Some owners report a “shudder” or “hard shifts.” This is often resolved with a PCM (Powertrain Control Module) software update or a fluid change. It is rarely a total mechanical failure if maintained properly.
How do I know if my water pump is failing?
Watch for a “Low Coolant” light and check your oil. If the oil looks like cream-colored sludge, the pump has failed internally. Also, look for coolant dripping from the weep hole behind the alternator.
Can I drive with a broken rear toe link?
No. Driving with a broken toe link is extremely dangerous. The rear wheel can kick outward, causing you to lose control of the vehicle. If you suspect a suspension failure, have the vehicle towed.
