By following these expert insights, you can ensure your SUV remains a dependable partner for thousands of miles to come. Let’s dive into the technical details of what makes this vehicle tick.
Understanding the ford explorer 2020 Platform
The 2020 redesign brought the longitudinal engine layout back to the lineup, which fundamentally changed how the vehicle handles and how you access parts under the hood. Unlike the 2019 models, the 2020 version offers a more balanced weight distribution, making it a favorite for those who enjoy a more spirited driving experience. This layout also simplifies certain repairs, as the accessory drive is more accessible than in transverse configurations.
Under the hood, you typically find one of three main powerplants: the 2.3L EcoBoost four-cylinder, the 3.0L twin-turbo V6 found in the ST and Platinum trims, or the 3.3L V6 Hybrid. Each engine has its own set of nuances regarding fluid capacities and thermal management. The 2.3L is a workhorse, but it requires diligent coolant level monitoring to prevent premature wear on the turbocharger seals.
The most significant change, however, is the 10R80 10-speed automatic transmission. This gearbox was co-developed with GM and is designed to keep the engine in its power band constantly. While efficient, it is a complex piece of machinery that requires specific Mercon ULV (Ultra-Low Viscosity) fluid. Using the wrong fluid in this transmission can lead to catastrophic internal failure, so always double-check your labels.
The CD6 Chassis and Suspension
The new chassis utilizes a mix of high-strength steel and aluminum to shed weight while increasing rigidity. For the DIYer, this means you need to be careful with jacking points. Always consult your owner’s manual before placing a floor jack under the frame to avoid damaging the aluminum suspension components.
The rear-wheel-drive bias also means that the rear differential requires regular inspections, especially if you use the Intelligent 4WD system frequently in muddy or snowy conditions. Look for signs of weeping around the axle seals during every oil change. Catching a small leak early can save you from a multi-thousand-dollar differential rebuild down the road.
Essential Maintenance for the Modern DIYer
Regular maintenance is the bedrock of vehicle longevity, and the 2020 Explorer is no exception. Because of the direct injection nature of the EcoBoost engines, carbon buildup on the intake valves can become an issue over time. To mitigate this, we recommend using high-quality synthetic oil and following a strict 5,000 to 7,500-mile change interval, regardless of what the “Oil Life Monitor” says.
For a standard oil change on the 2.3L engine, you will need approximately 6 quarts of 5W-30 synthetic oil and a Motorcraft FL-910S filter. The drain plug is often a plastic “yellow” plug that can be removed by hand or with a large flathead screwdriver. Be careful not to over-tighten this plug when reinstalling it, as the plastic tabs can snap, leading to a slow but persistent leak.
Don’t forget the cabin air filter, which is located behind the glovebox. Many owners neglect this, leading to poor AC performance and a musty smell in the cabin. Replacing this every 15,000 miles is a simple 10-minute job that requires no tools and significantly improves air quality for your passengers during long road trips.
Brake System and Fluid Flush
The 2020 model features an electronic parking brake and a sophisticated ABS module that integrates with the adaptive cruise control. When performing a brake job, you may need a diagnostic scan tool to put the rear calipers into “Service Mode.” Attempting to compress the rear pistons without doing this can damage the electronic parking brake motor.
We recommend a full brake fluid flush every two to three years. Brake fluid is hygroscopic, meaning it absorbs moisture from the air over time. This moisture can cause internal corrosion in the expensive ABS valves. Use a high-quality DOT 4 LV fluid to maintain the fast response times required by the vehicle’s safety systems.
Troubleshooting Common Reliability Concerns
Every vehicle has its quirks, and the ford explorer 2020 is known for a few specific issues that owners should monitor. One of the most common complaints involves the 10-speed transmission’s shifting logic. Some drivers experience “harsh shifts” or “gear hunting,” particularly when the transmission is cold. Often, a software update from the dealership (PCM/TCM flash) can resolve these behavior issues.
Another area to watch is the infotainment system. The Sync 3 system is generally robust, but the 10.1-inch vertical screen found in higher trims has been known to freeze or suffer from “ghost touching.” Before assuming the hardware is bad, try a master reset in the settings menu or check for over-the-air (OTA) software updates via your home Wi-Fi.
Mechanically, keep an ear out for a high-pitched whistling noise from the engine bay on the 3.0L V6 models. This can sometimes indicate a leak in the intercooler piping or a failing PCV valve. Addressing vacuum leaks early is vital for maintaining fuel economy and preventing the engine from running “lean,” which can damage the spark plugs and cylinders.
Addressing Recall Items
The 2020 model year had several high-profile recalls, including issues with the rearview camera and the “rollaway” risk involving the parking pawl. If you are buying one used, or haven’t checked lately, visit the NHTSA website and enter your VIN number. Ensuring these safety recalls are performed by a certified dealer is free and essential for your safety.
Specifically, the rear subframe bolt issue is one that off-roaders should pay attention to. In some units, the mounting bolt could break under high stress, leading to significant vibration and potential loss of control. If you plan on towing heavy loads or hitting washboard roads, verify that your subframe mounts are secured with the updated hardware.
Preparing Your Explorer for Off-Road Adventures
While many see the Explorer as a “mall crawler,” the 2020 model is surprisingly capable off-road, especially when equipped with the Terrain Management System. This system adjusts throttle response, traction control, and shift points to match surfaces like sand, mud, or snow. However, the factory tires are often the weak link for serious trail work.
If you want to venture off the beaten path, your first upgrade should be a set of All-Terrain (A/T) tires. Moving to a slightly more aggressive tread pattern will provide the grip needed for loose climbs. Be mindful of tire size; going too large without a lift kit can cause rubbing on the inner fender liners when the suspension is fully compressed.
For those looking for more ground clearance, several reputable companies offer 2-inch leveling kits. These kits typically use spacers on top of the factory struts. While they don’t increase suspension travel, they do allow for better approach and departure angles, which are critical when navigating rocky terrain or deep ruts.
Essential Trail Gear
When heading into the wilderness, never rely solely on your vehicle’s electronics. Always carry a basic recovery kit that includes a tow strap, a pair of soft shackles, and a portable air compressor. Airing down your tires to 20-25 PSI can dramatically increase your footprint on soft sand, but you must be able to air them back up before hitting the highway.
If you find yourself stuck, remember that the 2020 Explorer uses a unibody construction. Only use the designated recovery points or a hitch-mounted shackle for pulling. Never wrap a strap around a suspension arm or a bumper cross-member, as you will likely cause structural damage to the vehicle.
Advanced Driver Assistance Systems (ADAS) Maintenance
The 2020 Explorer is packed with technology like Ford Co-Pilot360, which includes lane-keeping assist, blind-spot monitoring, and pre-collision assist. These systems rely on a suite of cameras and radar sensors located behind the rearview mirror and inside the front bumper. Keeping these areas clean is the simplest way to ensure the systems function correctly.
If you replace your windshield due to a rock chip, be aware that the front-facing camera must be recalibrated. Many glass shops can do this, but if the calibration is off even by a fraction of a degree, your lane-keeping assist may “ping-pong” between lines or fail to activate. Always insist on an OEM-spec windshield to ensure the glass clarity meets the camera’s requirements.
Similarly, if you install a heavy-duty brush guard or a winch mount, ensure it does not block the radar sensor located in the lower grille. Obstructions here will disable your adaptive cruise control and emergency braking features. Many aftermarket manufacturers now offer “sensor-relocation kits” specifically for the 2020 and newer Explorer models.
Frequently Asked Questions About the ford explorer 2020
What is the towing capacity of the 2020 Explorer?
When properly equipped with the Class IV Trailer Tow Package, the 2.3L EcoBoost can tow up to 5,300 lbs, while the 3.0L V6 models can handle up to 5,600 lbs. Always use a weight-distributing hitch for trailers exceeding 5,000 lbs to maintain steering control and braking stability.
Does the 2020 Explorer require premium fuel?
While the EcoBoost engines can run on 87-octane regular unleaded, Ford recommends using 91 octane or higher for best performance, especially when towing or driving in hot weather. Higher octane helps prevent “knock” and allows the computer to advance timing for maximum power output.
How do I fix the “Deep Sleep Mode” battery issue?
Some owners report the vehicle entering “Deep Sleep Mode” frequently, which disables remote start and FordPass features to save the battery. This is often caused by a parasitic draw or a weak battery from the factory. Upgrading to a high-quality AGM (Absorbent Glass Mat) battery often solves this problem permanently.
Is the 10-speed transmission reliable?
The 10R80 transmission is generally reliable but is very sensitive to fluid levels and software calibration. If you notice erratic shifting, check for Technical Service Bulletins (TSBs) at your dealer. Regular fluid changes every 60,000 miles (instead of the 150,000-mile factory recommendation) will greatly extend its lifespan.
Conclusion: Keeping Your Explorer on the Road
The ford explorer 2020 is a versatile, powerful SUV that offers a lot to the modern driver, provided you stay ahead of its maintenance needs. By understanding the shift to the RWD platform and keeping a close eye on the 10-speed transmission and electronic systems, you can avoid the most common pitfalls associated with this model year. Remember that preventative care is always cheaper than reactive repairs.
Whether you are performing your own oil changes in the driveway or prepping for an overland journey, the key is to use the right parts and follow safe procedures. Use high-quality synthetic fluids, respect the torque specs, and don’t ignore the early warning signs of mechanical wear. With the right approach, your Explorer will be ready for whatever the road—or the trail—throws your way.
