Understanding Common Problems with Ford Explorer Generations
Ford Explorers span multiple generations, each with its unique design and, consequently, its own set of common ailments. Recognizing which generation your vehicle belongs to can often help pinpoint potential issues more quickly.
From the rugged, body-on-frame models of the 90s to the unibody, car-based SUVs of today, the Explorer’s evolution has introduced and resolved various engineering challenges. Let’s delve into some of the most frequently reported troubles.
Early Generations (1st-3rd Gen: 1991-2005)
These older models are known for their robust frames but can suffer from age-related wear. Transmission woes, particularly with the 5R55S automatic transmission, are a common complaint.
Owners often report harsh shifting, delayed engagement, or complete transmission failure. Regular fluid changes, though not a guaranteed fix, can sometimes extend the life of these units.
Mid-Generations (4th-5th Gen: 2006-2019)
The 4th generation saw improvements but still carried over some transmission concerns. The 5th generation, moving to a unibody platform, introduced new issues, particularly with electrical systems and power steering.
The electric power steering (EPS) can be a source of frustration, leading to a sudden loss of power assist. This can be a significant safety concern, especially when navigating tight turns or maneuvering in parking lots.
Current Generation (6th Gen: 2020-Present)
While newer, these models aren’t entirely exempt from early teething issues. Owners have reported concerns with infotainment systems, specific engine noises, and some fit-and-finish complaints.
Staying updated with factory recalls and technical service bulletins (TSBs) is crucial for newer models. These documents often highlight known issues and their official remedies.
Powertrain and Transmission Troubles
The heart of any SUV is its powertrain, and the Explorer has seen its share of engine and transmission challenges. These are often the most complex and costly repairs.
Being aware of early warning signs can prevent minor issues from escalating into major overhauls, keeping you safe on long trips or remote trails.
Transmission Shifting Issues
As mentioned, the 5R55S transmission in older models is notorious. Symptoms include a delayed shift into reverse or drive, hard shifts, or the “limp home” mode activating.
This often stems from worn solenoids, valve body issues, or internal clutch pack wear. A transmission fluid and filter change might offer a temporary reprieve, but a professional diagnosis is usually required.
For DIYers, checking the transmission fluid level and condition is the first step. Look for dark, burnt-smelling fluid, which indicates internal wear. If you’re tackling this, ensure you use the correct Mercon V fluid specified by Ford.
Engine Performance Problems
Various engines have powered the Explorer, from V6s to EcoBoost V6s and V8s. Common engine problems include misfires, coolant leaks, and timing chain issues.
Misfires can often be traced to faulty spark plugs, ignition coils, or fuel injectors. A simple diagnostic scan tool (OBD-II scanner) can pull trouble codes like P0301 (Cylinder 1 Misfire), helping you narrow down the culprit.
Coolant leaks, particularly from the water pump or thermostat housing, are not uncommon. Keep an eye on your coolant level and any puddles under the vehicle. A sweet smell can also indicate a coolant leak.
Some EcoBoost engines have reported issues with carbon buildup on intake valves due to direct injection, which can lead to reduced performance and misfires. Fuel system cleaners designed for direct injection engines can help, but sometimes a professional intake valve cleaning is necessary.
Electrical and Sensor Glitches
Modern vehicles are packed with electronics, and the Explorer is no exception. Electrical gremlins can manifest in various frustrating ways, from minor annoyances to critical safety concerns.
These issues often require careful diagnosis, as symptoms can sometimes point to multiple potential causes. Always start with the simplest checks.
Electric Power Steering (EPS) Failure
The 5th generation Explorer (2011-2019) is particularly susceptible to EPS module failure. This can result in a sudden loss of power steering, making the vehicle incredibly difficult and dangerous to steer.
If you experience this, pull over immediately in a safe location. While the steering will still function mechanically, the effort required will be significantly higher. This issue almost always requires professional repair, often involving replacing the entire steering rack assembly.
HVAC Blend Door Actuator Issues
A common complaint across several generations involves the heating, ventilation, and air conditioning (HVAC) system, specifically the blend door actuators. These small motors control the airflow and temperature within the cabin.
Symptoms include only hot air or only cold air blowing, or air not directing to the correct vents (e.g., stuck on defrost). You might also hear a clicking or ticking sound from behind the dashboard.
While replacing these can be a DIY task, it often involves removing parts of the dashboard. Be prepared with a set of trim removal tools and a good service manual. Always disconnect the battery before working on electrical components.
Battery Drain and Charging System Problems
Parasitic battery drains are frustrating and can leave you stranded. Common culprits include faulty modules that don’t power down, interior lights staying on, or aftermarket accessories drawing power.
To diagnose, you’ll need a multimeter. After ensuring all accessories are off and doors are closed, disconnect the negative battery terminal. Connect the multimeter in series between the battery post and the cable, set to amperage. A draw over 50 milliamps (0.05 amps) indicates a parasitic drain. Then, systematically pull fuses until the draw drops, identifying the problematic circuit.
Charging system issues, like a failing alternator, can also lead to a dead battery. Watch for the battery light on your dashboard or dimming headlights. A quick check with a voltmeter should show around 13.5-14.5 volts across the battery terminals when the engine is running.
Steering, Suspension, and Braking Concerns
These systems are critical for vehicle control, comfort, and safety. Any issues here demand prompt attention, especially if you venture off-road or carry heavy loads.
Neglecting suspension or braking problems can lead to dangerous situations and accelerated wear on other components.
Suspension Component Wear
Explorers, especially those driven on rough roads or off-road, can experience premature wear of suspension components like control arm bushings, sway bar links, and shock absorbers.
Symptoms include clunking noises over bumps, excessive body roll, uneven tire wear, or a generally “loose” feeling in the steering. Visually inspect these components for torn boots, excessive play, or fluid leaks from shocks.
Replacing sway bar links is often a straightforward DIY job with basic hand tools and a jack. For control arms or more complex suspension work, consider your skill level and access to appropriate equipment like spring compressors. Always use jack stands when working under the vehicle.
Brake System Pulsations and Wear
Brake pulsations, often felt through the pedal or steering wheel, usually indicate warped brake rotors. This can be exacerbated by towing or heavy braking, especially with older models.
While rotors can sometimes be machined, replacing them along with new brake pads is often the best solution for smooth, reliable braking. Remember to bed in new pads and rotors properly after installation.
If you notice a soft brake pedal or increased stopping distances, check your brake fluid level and inspect for leaks at the calipers, lines, or master cylinder. Air in the brake lines will also cause a spongy pedal, requiring a brake bleed.
HVAC and Interior Annoyances
Beyond the critical mechanical systems, interior comfort and convenience issues can significantly detract from the ownership experience.
While often less urgent, these problems can still be frustrating, especially on long road trips or when dealing with extreme weather.
Interior Trim and Panel Rattles
Over time, various interior trim pieces, especially on older models, can develop rattles and squeaks. This is often due to loose clips or panels vibrating against each other.
Systematically pressing on trim pieces while driving can help pinpoint the source. Small pieces of felt tape or foam weatherstripping can often silence these annoying noises without major disassembly.
Power Window Regulator Failure
Another common issue in various Explorer generations is the failure of power window regulators. This leads to windows that won’t go up or down, or move slowly and unevenly.
Replacing a window regulator typically involves removing the interior door panel. It’s a manageable DIY task, but be prepared to carefully disconnect electrical connectors and potentially deal with sharp edges. Ensure you buy the correct regulator for your specific door (front/rear, driver/passenger).
