We will cover everything from the drivetrain and steering to the electrical gremlins that often plague this model year. Whether you are a weekend warrior or a daily commuter, understanding these issues is the first step toward a reliable ownership experience.
Common Ford Explorer 2014 Sport Problems and PTU Maintenance
The most discussed issue among the enthusiast community is the Power Transfer Unit, or PTU. This component is responsible for sending power to the rear wheels, making the Intelligent 4WD system possible.
In the 2014 Sport model, the PTU is tucked away near the exhaust manifold, which creates an incredible amount of heat. This heat causes the synthetic gear oil inside to break down much faster than Ford’s “lifetime” fluid claim suggests.
When the fluid breaks down, it turns into a thick, black sludge that resembles molasses. This leads to bearing failure, seal leaks, and eventually a total mechanical breakdown of the unit.
Symptoms of a Failing PTU
Keep an ear out for a high-pitched whining or grinding noise that increases with vehicle speed. You might also notice a distinct burning oil smell coming through the vents after a long highway drive.
If you see a leak, it often manifests as a thick, dark fluid dripping near the middle of the front subframe. At this stage, the internal gears may already be suffering from excessive friction and wear.
The DIY Fix: Frequent Fluid Changes
While Ford does not always include a drain plug on these units, many DIYers use a vacuum extraction pump to suck the old fluid out through the fill hole. Replacing this fluid every 30,000 miles is the best way to prevent failure.
Use a high-quality 75W-140 full synthetic gear lubricant to handle the extreme temperatures. This simple maintenance step can save you over $1,500 in replacement costs later on.
The EcoBoost Cooling System and Internal Water Pump Risks
When diagnosing ford explorer 2014 sport problems, the cooling system deserves a deep dive. The 3.5L EcoBoost engine uses a water pump that is driven by the timing chain and located inside the engine block.
This design is controversial because if the water pump seal fails, the coolant can leak directly into the oil pan. When coolant mixes with oil, it destroys the engine’s ability to lubricate its bearings, leading to catastrophic engine failure.
Because the pump is hidden behind the timing cover, you cannot easily see it leaking. You must rely on secondary signs to catch a failure before it kills your motor.
How to Spot a Hidden Coolant Leak
Check your coolant reservoir level weekly; if it is dropping but you see no puddles on the ground, it may be leaking internally. Pull your oil dipstick and look for a milky, coffee-colored substance.
If the oil looks frothy or light brown, stop driving immediately. You should also look for “weeping” from a small hole located behind the alternator, which is the designated drain path for a failing pump.
Pro Tip: Replace the Timing Chain Simultaneously
Because reaching the water pump requires removing the front of the engine, the labor cost is high. If you are paying a pro or doing the work yourself, always replace the timing chain and tensioners at the same time.
This “while you’re in there” approach ensures that you won’t have to tear the engine down again for another 100,000 miles. Use only OEM Motorcraft parts for this specific repair to ensure fitment and durability.
Electric Power Assisted Steering (EPAS) Failures
The 2014 Explorer Sport uses an electric steering rack rather than a traditional hydraulic pump. While this improves fuel economy and allows for “Park Assist” features, the EPAS system has a history of sudden failure.
A failure usually begins with a “Steering Assist Fault” message on the dashboard. In some cases, the steering may become incredibly heavy, making the vehicle difficult to turn at low speeds.
This is often caused by a faulty internal sensor or a motor failure within the rack itself. Because the unit is a sealed electronic component, the entire rack usually needs replacement.
Safety First: Handling a Steering Loss
If your steering assist fails while driving, do not panic. The vehicle is still steerable, but it will require significantly more physical effort to turn the wheel.
Slow down gradually and pull over to a safe area. Sometimes cycling the ignition can temporarily reset the module, but this is a sign that the hardware is failing and needs immediate professional attention.
Checking for Recalls
Ford has issued several recalls and extended warranties for steering issues on various Explorer models. Before spending thousands on a new rack, run your VIN (Vehicle Identification Number) through the NHTSA website to see if you qualify for a free repair.
Even if your specific vehicle isn’t covered, documenting the failure with Ford can help in future safety investigations. Always keep your receipts for any steering-related repairs.
Suspension and Rear Toe Link Concerns
The Sport trim features a firmer suspension tuned for handling, but the heavy weight of the Explorer puts a lot of stress on the rear components. A common issue involves the rear toe links, which help keep the rear wheels aligned.
If a toe link snaps, the rear wheel can pivot independently, leading to a sudden loss of control. This is especially dangerous at highway speeds or when navigating slippery off-road trails.
Listen for “clunking” or “popping” noises coming from the rear when going over bumps. You may also notice the vehicle “wandering” or feeling unstable in corners.
Inspecting the Rear Suspension
Jack up the rear of the car and safely support it on jack stands. Grasp the rear tire at the 3 o’clock and 9 o’clock positions and shake it firmly.
If you feel any play or hear a clicking sound, the toe link bushings or the link itself may be worn out. Replacing these is a relatively straightforward DIY job that requires basic sockets and a torque wrench.
After any suspension work, you must take the vehicle to a shop for a four-wheel alignment. This ensures your tires wear evenly and the vehicle tracks straight down the road.
Turbocharger Health and Carbon Buildup
The twin-turbochargers on the 2014 Sport provide that addictive torque, but they require clean oil and proper cooling. Addressing ford explorer 2014 sport problems before they become catastrophic often starts with turbo maintenance.
Because the EcoBoost is a Direct Injection (DI) engine, fuel is sprayed directly into the cylinder rather than over the intake valves. This means the valves are never “washed” by gasoline, leading to carbon deposits.
Over time, this carbon buildup can cause rough idling, reduced fuel economy, and a loss of top-end power. It can also cause “pre-ignition,” which is damaging to the pistons.
Preventing Carbon Issues
Use a high-quality intake valve cleaner every 10,000 miles to help dissolve light deposits. Additionally, installing a “catch can” in the PCV system can prevent oil vapors from reaching the valves in the first place.
Always use the recommended 5W-30 full synthetic oil and change it every 5,000 miles. Frequent oil changes prevent the turbo oil feed lines from clogging with sludge, which is a leading cause of turbo failure.
Identifying Turbo Wear
Look for blue smoke from the exhaust during a cold start or under heavy acceleration. This usually indicates that the turbo seals are leaking oil into the intake or exhaust stream.
A “boost leak” might sound like a loud whistling or rushing air noise when the turbos spool up. Check all your intercooler piping and rubber boots for cracks or loose clamps.
Essential Tools for DIY Maintenance
To successfully manage the common ford explorer 2014 sport problems, you need a few specific tools in your garage. Having these on hand will save you time and frustration during repairs.
- OBD-II Scanner: Essential for reading “Check Engine” lights and monitoring live data like boost pressure and coolant temps.
- Vacuum Fluid Extractor: The best tool for changing the “unserviceable” PTU fluid without removing the unit.
- Torque Wrench: Critical for suspension components and wheel lugs to ensure safety and prevent part failure.
- Long-Reach Sockets: Useful for reaching the deep-set bolts on the EcoBoost engine and various heat shields.
- Digital Multimeter: Necessary for troubleshooting the MyFord Touch system and other electrical gremlins.
Investing in a set of service ramps or high-capacity jack stands is also a must. The Explorer is a heavy vehicle, and safety should always be your top priority when working underneath it.
Frequently Asked Questions About Ford Explorer 2014 Sport Problems
How long do the turbos last on a 2014 Ford Explorer Sport?
With meticulous maintenance, the turbos can last well over 150,000 miles. However, poor oil change habits can lead to failure as early as 80,000 miles. Always let the engine idle for a minute after a hard drive to allow the turbos to cool down.
Is the PTU failure avoidable?
Yes, in most cases. The failure is almost always caused by fluid degradation due to heat. By changing the PTU fluid every 30,000 miles, you significantly reduce the risk of the internal gears seizing or the seals failing.
What are the most expensive ford explorer 2014 sport problems to fix?
The internal water pump and the PTU are the most expensive. A water pump failure can cost $2,000 to $3,000 in labor, or even more if the engine is destroyed. A new PTU typically costs between $1,500 and $2,200 including labor.
Why does my MyFord Touch screen keep freezing?
This is usually a software issue. Ensure you have the latest SYNC update installed. You can also perform a “master reset” in the settings menu or pull the fuse for the infotainment system to force a hard reboot.
Should I use Premium fuel in my 2014 Explorer Sport?
While the Sport can run on 87 octane, 91 or 93 octane is highly recommended. Premium fuel helps prevent engine knock and allows the EcoBoost engine to reach its full rated horsepower and torque, especially in hot weather.
Final Thoughts on Keeping Your Sport on the Road
Owning a 2014 Ford Explorer Sport is a rewarding experience if you are willing to be a proactive owner. By understanding the common hurdles—like the PTU fluid and the internal water pump—you can enjoy the performance without the fear of a breakdown.
Remember that preventative maintenance is always cheaper than emergency repairs. Treat your EcoBoost engine to high-quality synthetic oil, keep your cooling system sealed, and don’t ignore those strange drivetrain noises.
Whether you’re hauling the family to a campsite or enjoying a spirited drive on a winding backroad, a well-maintained Explorer is a beast of a machine. Stay vigilant, keep your tools ready, and stay safe on the road!
