Identifying Common 2017 ford explorer problems
Every vehicle has its quirks, but the 2017 Ford Explorer has a few specific areas that demand your attention. Most of these issues stem from the 3.5L Ti-VCT V6 engine and the rear suspension geometry. Recognizing the early warning signs can prevent a minor leak from becoming a total engine replacement.
If you notice a sweet smell coming from the engine bay or a strange clunking sound when hitting bumps, you are likely experiencing a known issue. These symptoms often point to the water pump or the rear toe links, both of which are high-priority repairs. Addressing these 2017 ford explorer problems early is the key to longevity.
The Internal Water Pump: The Engine Killer
The most significant concern for owners of the 3.5L V6 engine is the internal water pump. Unlike most vehicles where the pump is external and easy to see, 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 “chocolate milk” mixture of oil and coolant that destroys engine bearings in minutes. To catch this early, check your oil dipstick frequently for any milky residue or a rising oil level. Use a coolant pressure tester to see if the system holds pressure; if it drops without a visible external leak, the pump is likely the culprit.
Replacing this pump is a massive job that involves removing the front of the engine and the timing chain. If you are a DIYer, set aside a full weekend and ensure you have a torque wrench and a timing tool kit. If the pump fails completely while driving, the engine will likely be a total loss, so treat this as a preventative maintenance item if you are over 100,000 miles.
Transmission and Drivetrain Reliability
The 6F55 6-speed automatic transmission in the 2017 Explorer is generally robust, but it is not without its faults. Some owners report harsh shifting, especially when moving from second to third gear. This is often caused by a failing solenoid or a software glitch in the Powertrain Control Module (PCM).
If you experience “hunting” for gears or a delay when shifting into reverse, start by checking the transmission fluid level. Ford claims the fluid is “lifetime,” but experienced mechanics recommend changing it every 30,000 to 50,000 miles. Fresh fluid can solve many minor shifting issues before they require a rebuild.
Power Transfer Unit (PTU) Overheating
For those with Intelligent 4WD, the PTU is a common failure point, especially during heavy towing or off-roading. The PTU sits very close to the exhaust, which cooks the gear oil inside until it turns into a thick sludge. This leads to internal gear failure and a “clunking” sound from the front end.
To prevent this, change the PTU fluid every 30,000 miles, even if the manual says otherwise. You will need a fluid extraction pump to suck the old oil out through the fill plug, as most units do not have a drain plug. Use a high-quality 75W-140 synthetic gear oil to better handle the heat generated by the exhaust system.
Suspension and Steering Concerns
The 2017 Ford Explorer has been the subject of multiple recalls regarding its rear suspension. The most notable involves the rear suspension toe links, which are prone to snapping under stress. A snapped toe link causes a sudden loss of steering control in the rear, which is incredibly dangerous at highway speeds.
Listen for a metallic clicking or popping sound when you go over bumps or turn the wheel. If the rear of the car feels “loose” or “walks” over uneven pavement, inspect the toe links immediately. Ford has issued recalls for this, so check your VIN on the NHTSA website to see if you qualify for a free replacement.
Electric Power Assisted Steering (EPAS) Failure
Some owners have reported a sudden loss of power steering while driving. This is usually due to a fault in the EPAS motor or a sensor error within the steering rack. If the “Power Steering Assist Fault” message appears on your dash, the steering will become very heavy, making the vehicle difficult to maneuver.
Before replacing the expensive steering rack, check the battery and alternator. The EPAS system is very sensitive to voltage drops. A weak battery can trigger false steering codes. If the battery is healthy, you may need an OBDII scanner to clear the codes or recalibrate the steering angle sensor.
Exhaust Odors and Cabin Safety
One of the most widely reported 2017 ford explorer problems involves the smell of exhaust fumes inside the cabin. This typically occurs during hard acceleration or when using the air conditioning in “recirculation” mode. This is more than just an annoyance; it is a safety risk due to carbon monoxide exposure.
The issue often stems from unsealed body seams behind the rear bumper or a faulty liftgate seal. Ford released several Technical Service Bulletins (TSBs) to address this. Owners can help mitigate this by ensuring the rear liftgate glass is fully closed and checking for any cracks in the exhaust manifold.
Cracked Exhaust Manifolds
The EcoBoost engines, in particular, are known for cracking exhaust manifolds. This allows raw exhaust to leak into the engine bay, where it is then sucked into the HVAC system. If you hear a ticking sound that disappears once the engine warms up, you likely have a cracked manifold or a broken manifold bolt.
Replacing the manifold is a labor-intensive task, especially on the rear bank of the V6. Use penetrating oil on the studs several days before the job to prevent them from snapping. Always use a new gasket and follow the specific torque sequence to ensure a proper seal and prevent future leaks.
Electrical and SYNC 3 Troubleshooting
The SYNC 3 infotainment system in the 2017 Explorer is a massive upgrade over previous versions, but it still has its share of glitches. Common complaints include the screen freezing, the backup camera not displaying, or Bluetooth connectivity dropping out. Most of these issues are software-related rather than hardware failures.
The first step for any SYNC issue is a “Master Reset” through the settings menu. If that doesn’t work, check for a software update on Ford’s website. You can download the update to a USB drive and install it yourself. This often fixes bugs related to Apple CarPlay and Android Auto compatibility.
Backup Camera Reliability
If your backup camera shows a blue screen or a distorted image, the problem is usually a loose connection or a failing camera module. The wiring harness that passes through the liftgate can become pinched over time. Open the liftgate and inspect the wiring loom for any signs of fraying or broken wires.
If the wiring looks good, the camera module itself may need replacement. This is a relatively simple DIY fix that involves removing the interior trim panel of the liftgate. You can find OEM replacement cameras online for a fraction of the dealership price, and the installation takes less than an hour with basic hand tools.
Body and Paint Durability
Many 2017 Explorer owners have noticed bubbling paint on the leading edge of the hood. This is caused by aluminum corrosion under the paint. Since the hood is aluminum, it reacts differently to moisture and contaminants if the factory primer was not applied correctly.
Unfortunately, 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, contact your dealer. Otherwise, keep the edge of the hood waxed and clean to slow the progression of the oxidation.
Frequently Asked Questions About 2017 ford explorer problems
How can I tell if my water pump is failing?
Look for a low coolant level without any external puddles under the car. Check your oil dipstick; if the oil looks like a light-colored milkshake, the internal seal has failed. You might also hear a whining noise from the front of the engine that changes with RPM.
Is the 2017 Ford Explorer safe to drive with the exhaust smell?
No, you should not ignore the smell of exhaust in the cabin. Carbon monoxide is odorless and colorless, and it can cause dizziness or loss of consciousness. Use a portable carbon monoxide detector in the cabin until you can get the seals and exhaust system inspected by a professional.
What should I do if my rear suspension feels loose?
Stop driving and inspect the rear toe links immediately. These parts are known to snap, which can cause the rear wheel to turn independently of the vehicle. Check the NHTSA website for recall 19V416 or 20V675 to see if your Explorer is covered for a free repair.
How often should I change the PTU fluid?
While Ford often labels the PTU fluid as “fill for life,” most enthusiasts and mechanics recommend changing it every 30,000 miles. This is especially important if you live in a hot climate or use your Explorer for towing or off-road driving.
Does the 2017 Ford Explorer have transmission problems?
The 6-speed transmission is generally reliable but can suffer from harsh shifts or solenoid failures. Regular fluid changes (every 50,000 miles) and ensuring your battery is in good condition can prevent the majority of electronic shifting issues.
