Let’s roll up our sleeves and look at what makes these SUVs tick—and what occasionally makes them stop.
Understanding ford explorer problems in the Drivetrain
The drivetrain is the heart of your vehicle’s mobility, and unfortunately, it has been a historical weak point for many Explorer models. If you feel a shudder while shifting or hear a strange clunking noise when putting the car in gear, you are likely dealing with a transmission or transfer case issue. These components require precise maintenance to avoid catastrophic failure.
Transmission Shifting Issues and Flares
The 5R55 series transmissions, found in the early 2000s models, are notorious for shifting “flares.” This happens when the engine RPMs spike momentarily between gear changes. This usually indicates that the solenoid pack or the internal bands are wearing out.
For DIYers, checking the transmission fluid level is the first step, though many newer models lack a traditional dipstick. You may need to use a specialized fill plug adapter and check the level from under the vehicle while the engine is running. Always use the specific fluid recommended in your manual, such as Mercon V or Mercon LV.
PTU Overheating in AWD Models
In modern front-wheel-drive-based Explorers (2011–2019), the Power Transfer Unit (PTU) often suffers from fluid breakdown. The PTU sits very close to the exhaust manifold, which subjects the lubricant to extreme heat. Over time, the fluid turns into a thick, black sludge that fails to protect the gears.
If you notice a “burnt toast” smell after a long drive, your PTU fluid is likely cooked. While Ford often labeled this fluid as “lifetime,” experienced technicians recommend changing it every 30,000 miles. This is especially important if you frequently use your Explorer for towing or off-roading.
Engine Performance and Internal Cooling Failures
Engine reliability varies significantly across the different powerplants Ford has offered. While the newer EcoBoost engines offer impressive power, they come with their own set of maintenance requirements. Older naturally aspirated engines are simpler but have well-documented mechanical flaws that require a watchful eye.
The 3.5L Duratec Internal Water Pump
One of the most critical engine-related ford explorer problems involves the 3.5L Cyclone/Duratec V6. In this design, the water pump is driven by the timing chain and sits inside the engine front cover. If the pump seal fails, coolant can leak directly into the oiling system.
This “hidden” leak creates a milky sludge that destroys engine bearings within miles. To prevent total engine loss, regularly check your oil dipstick for a “chocolate milk” appearance. If you see the coolant level dropping in the reservoir with no visible external leaks, stop driving immediately and consult a professional.
The 4.0L SOHC Timing Chain “Death Rattle”
Owners of the older 4.0L SOHC V6 engines are likely familiar with the dreaded timing chain rattle. The plastic guides and hydraulic tensioners in these engines are prone to breaking. Once they fail, the chain can slap against the engine casing or, worse, skip a tooth and cause valve damage.
Replacing these guides is a labor-intensive job that often requires removing the engine. If you hear a metallic rattling sound between 2,000 and 3,000 RPM, do not ignore it. Using high-quality synthetic oil and OEM Ford filters can help extend the life of these sensitive tensioners.
Turbocharger Health in EcoBoost Models
The 2.3L and 3.5L EcoBoost engines rely on turbochargers to provide power. These components spin at incredibly high speeds and require clean oil for cooling and lubrication. Common issues include oil leaks at the turbo feed lines and wastegate rattle.
To keep your turbos healthy, let the engine idle for a minute after a spirited drive or a heavy tow. This allows the oil to circulate and cool the turbo bearings. If you notice blue smoke from the exhaust or a significant loss of power, your turbo seals may be failing.
Suspension and Steering Safety Concerns
A vehicle that handles poorly is a safety risk, especially for a top-heavy SUV. The Ford Explorer has faced several recalls and technical service bulletins related to its chassis. Keeping your suspension in top shape is vital for both highway comfort and trail capability.
Rear Toe Link Failures
A major concern for the fifth-generation Explorer (2011–2019) is the rear suspension toe link. These links can fracture due to stress and corrosion, leading to a sudden loss of steering control in the rear. This issue is so prevalent that it has been the subject of massive safety recalls.
If you feel the rear of your car “fishtailing” or wandering over bumps, inspect the rear links immediately. Look for cracks or excessive play in the bushings. For those who take their Explorers off-road, upgrading to heavy-duty aftermarket links can provide extra peace of mind.
Electric Power Assisted Steering (EPAS) Glitches
Modern Explorers use an electric motor for steering assist rather than a hydraulic pump. While this improves fuel economy, the EPAS system can fail without warning. Owners often report a “Steering Assist Fault” message followed by a complete loss of power steering.
Sometimes this is caused by a low battery or a bad ground connection. However, internal sensor failures often require the replacement of the entire steering rack. Always ensure your battery and alternator are in peak condition, as voltage drops can trigger sensitive electronic steering modules.
Electrical Systems and Infotainment Gremlins
As vehicles become more technologically advanced, electrical ford explorer problems have become more common. From frozen screens to faulty sensors, these issues are rarely dangerous but are incredibly frustrating for the modern driver.
Sync Infotainment System Crashes
The Sync system is the brain of the Explorer’s interior. Version 2 (MyFord Touch) was notorious for lagging, freezing, and failing to connect to phones. While Sync 3 and Sync 4 are much improved, they can still experience software glitches that require a “master reset.”
To perform a reset, hold the power button and the “seek forward” button simultaneously for about ten seconds. Keeping your software updated via Wi-Fi can resolve many of these bugs. If the screen remains black, the APIM (Accessory Protocol Interface Module) may need replacement.
Backup Camera Failures
Recent Explorer models have been recalled for backup cameras that display a blue screen or a distorted image. This is often a hardware failure within the camera itself or a wiring harness issue in the liftgate. Since this is a federally mandated safety feature, check with your dealer to see if your vehicle is covered under a free repair program.
Door Latch and Sensor Issues
A common “ghost” in the machine is the “Door Ajar” warning light that stays on even when all doors are closed. This is usually caused by a dirty or faulty latch sensor. A quick DIY fix involves spraying the latch mechanism with electrical contact cleaner or WD-40 to loosen any stuck sensors.
Off-Road Readiness and Trail Challenges
If you use your Explorer for overlanding or light trail work, you are putting extra stress on components. Off-roaders need to be aware of how the Terrain Management System interacts with the vehicle’s hardware. Heat and dust are your primary enemies in the wilderness.
Managing the Terrain Management System
The Terrain Management System (TMS) adjusts throttle response, transmission shifts, and braking to optimize traction. However, using “Sand” or “Mud/Ruts” mode for extended periods can cause the AWD coupling to overheat. If the system gets too hot, it will temporarily revert to front-wheel drive to protect itself.
If you are planning a long beach drive or a muddy trail run, take frequent breaks to let the drivetrain cool. Also, ensure your tires are aired down appropriately for the terrain. This reduces the strain on the engine and transmission by allowing the tires to “float” over obstacles rather than digging in.
Protecting the Underbody
The Explorer does not have the same ground clearance as a dedicated rock crawler like the Bronco. Be mindful of the low-hanging plastic air dams and the exposed oil pan. Installing aftermarket skid plates is a wise investment if you frequently find yourself on rocky paths.
Always carry a basic recovery kit, including a tow strap, a shovel, and a portable air compressor. If you get stuck, avoid excessive wheel spin, which can quickly overheat the transmission fluid. Rely on your recovery gear rather than brute-forcing the vehicle out of a hole.
Maintenance Checklist to Prevent ford explorer problems
Preventative maintenance is the best way to avoid the expensive ford explorer problems discussed above. By following a strict schedule, you can catch wear and tear before it leads to a breakdown. Here is a checklist for the diligent owner:
- Every 5,000 Miles: Change oil and filter. Rotate tires and inspect brake pads.
- Every 30,000 Miles: Replace the engine air filter and cabin filter. Change the PTU and rear differential fluid (if applicable).
- Every 60,000 Miles: Inspect the cooling system hoses and perform a coolant pH test. Replace spark plugs on EcoBoost models.
- Every 100,000 Miles: Replace the water pump and timing chain tensioners as a proactive measure on 3.5L engines. Flush the transmission fluid.
Using a high-quality OBD-II scanner can also help you monitor the health of your vehicle. These tools allow you to read “pending” codes that haven’t yet triggered a dashboard light. Catching a small sensor error early can prevent a major component failure later on.
