2020 Ford Explorer Reliability – A Deep Dive Into Performance
The 2020 Ford Explorer represents a major shift for the iconic nameplate, moving to a rear-wheel-drive platform that improved towing and handling. While the redesign brought modern tech and powerful EcoBoost engines, early production models faced several growing pains that buyers and DIY mechanics should investigate. This guide breaks down the real-world durability of this SUV to help you maintain yours for the long haul.
Do you need a versatile family hauler that can actually handle a dirt trail without falling apart? Finding a used SUV often feels like a gamble, especially when a model undergoes a complete ground-up redesign like the Explorer did in 2020. You want to know if the 10-speed transmission will hold up or if the infotainment screen will go dark when you need navigation most.
In this comprehensive guide, we will analyze the 2020 ford explorer reliability based on technical service bulletins, owner reports, and mechanical teardowns. We will cover everything from the 2.3L EcoBoost engine’s longevity to the specific suspension components that might need an upgrade for off-road use. By the end, you will have a clear maintenance roadmap and the confidence to tackle common repairs yourself.
Our goal is to move past the surface-level reviews and get into the grease and bolts of what makes this vehicle tick. Whether you are a weekend warrior looking to tow a boat or a DIYer performing your own oil changes, these insights will save you time and money. Let’s dive into the mechanical heart of this sixth-generation Explorer.
Understanding 2020 ford explorer reliability After the Redesign
The 2020 model year was the debut of the sixth-generation Explorer, built on the CD6 platform. This was a massive departure from the previous front-wheel-drive architecture, promising better weight distribution and towing capacity. However, “first-year” models are notorious in the automotive world for having unrefined assembly processes and software bugs.
Early 2020 units produced at the Chicago Assembly Plant were subject to several high-profile recalls and quality control issues. Many of these involved wiring harness routing and trim pieces that weren’t properly secured. If you are shopping for one today, checking the “build date” on the driver-side door jamb is a critical first step for assessing potential headaches.
Despite the rocky start, the 2020 ford explorer reliability improved significantly as the production year progressed. Vehicles built in late 2020 benefited from updated assembly protocols and software patches for the transmission and infotainment systems. For the DIY mechanic, this means that while the bones of the car are solid, you must be diligent about checking for completed recall work.
The Impact of the CD6 Platform
The move to a longitudinal engine layout (front-to-back) made the engine bay more accessible for some repairs but tighter for others. For example, accessing the turbocharger on the 2.3L EcoBoost is relatively straightforward compared to transverse layouts. However, the rear-wheel-drive bias means there is now a driveshaft and a rear differential that require periodic fluid inspections.
For off-road enthusiasts, this platform change was a win, providing a more robust foundation for suspension lifts and larger tires. The downside is that the early 2020 models had some reports of driveshaft vibrations. If you feel a shudder at highway speeds, it is likely an issue with the center support bearing or the rear subframe bolts, which were part of a major recall.
Engine Performance: 2.3L EcoBoost vs. 3.0L Twin-Turbo V6
The base 2.3L I4 EcoBoost is a workhorse shared with the Mustang and Ranger, known for a decent balance of power and efficiency. In the Explorer, it produces 300 horsepower, which is plenty for daily driving and light trails. From a maintenance perspective, this engine is sensitive to oil quality due to its direct-injection system and turbocharger.
The 3.0L Twin-Turbo V6, found in the ST and Platinum trims, is a powerhouse that turns the Explorer into a performance SUV. While it offers thrilling acceleration, it adds complexity with dual turbos and a more cramped engine bay. If you prioritize 2020 ford explorer reliability, the 2.3L is generally the simpler engine to maintain over 100,000 miles.
One common issue across both engines is carbon buildup on the intake valves, a byproduct of direct injection. Since fuel doesn’t wash over the back of the valves, oil vapors can bake onto them over time. Using a high-quality catch can and performing an intake valve cleaning every 50,000 miles can prevent power loss and rough idling.
The Water Pump Concern
A major relief for 2020 owners is that Ford moved the water pump to the outside of the engine on these newer powerplants. In previous generations (the 3.5L Cyclone V6), the water pump was internal and driven by the timing chain. If it failed, it could dump coolant into the oil, destroying the engine.
On the 2020 models, a failing water pump will simply leak coolant onto the ground or cause overheating. This is a much more DIY-friendly design that significantly boosts long-term 2020 ford explorer reliability. Always keep an eye on your coolant reservoir levels; if you see a drop without a visible leak, inspect the turbocharger coolant lines for weeping.
The 10R80 Transmission: Smooth Shifting or Rough Rides?
The 10-speed automatic transmission, co-developed with GM, is the most discussed component of this vehicle. When working correctly, it keeps the engine in the optimal power band and aids fuel economy. However, many owners have reported harsh shifts, particularly between third, fourth, and fifth gears.
Most of these issues are software-related rather than mechanical failures. The transmission uses “adaptive learning” to adjust shift points based on your driving style. If the shift logic gets confused, it can cause a “clunk” during downshifts. A dealership can perform a PCM/TCM flash to reset this learning process, which often smooths out the ride.
For the DIYer, the best way to ensure transmission longevity is regular fluid changes. Ford claims the fluid is “lifetime,” but experienced mechanics suggest a drain and fill every 40,000 to 50,000 miles. Note that this transmission does not have a traditional dipstick; you must check the level via a small plug on the side of the transmission case while the fluid is at operating temperature.
Common Transmission “Quirks” to Watch For
- Delayed Engagement: A 2-3 second pause when shifting from Park to Drive or Reverse.
- Gear Hunting: The transmission shifting frequently on slight inclines; often fixed with a software update.
- CDF Drum Issues: A more serious internal mechanical issue where a sleeve moves, blocking oil flow. This usually triggers a Check Engine Light and requires a professional rebuild.
Suspension and Braking: Preparing for the Trail
The 2020 Explorer uses a MacPherson strut front suspension and a multi-link rear setup. For the average commuter, it offers a car-like ride. For the off-roader, the ground clearance is a bit low at 7.9 to 8.2 inches. If you plan on hitting rocky trails, a 2-inch leveling kit is a popular modification that doesn’t drastically compromise geometry.
One specific area of concern for 2020 ford explorer reliability is the rear subframe. There was a significant recall regarding the rear axle mounting bolt. In some cases, the bolt could fracture, causing the driveshaft to disconnect. If you are buying used, ensure the “bolt replacement and subframe inspection” has been performed by a Ford technician.
Brake wear on the 2020 Explorer is fairly standard, though the ST models with the High-Performance Brake Package use larger rotors and more aggressive pads. These will dust more and wear faster. For a DIY brake job, ensure you have a scan tool or the knowledge to put the Electronic Parking Brake (EPB) into “service mode” before compressing the rear calipers.
Upgrading for Off-Road Durability
- Skid Plates: The factory plastic splash guards offer zero protection against rocks. Replace them with steel or aluminum plates.
- All-Terrain Tires: Swapping the factory highway tires for something like a BFGoodrich KO2 will significantly improve traction and puncture resistance.
- Heavy-Duty Struts: If you carry a lot of camping gear, upgrading to Bilstein or Fox shocks can help manage the extra weight and prevent “bottoming out.”
Interior Electronics and the SYNC 3 System
The interior of the 2020 Explorer features either an 8-inch or a 10.1-inch vertical touchscreen. While the SYNC 3 system is generally more stable than the older MyFord Touch, it is not without faults. Some owners have experienced “blue screens” or complete system freezes, often solved by a hard reset (holding the power and “seek forward” buttons simultaneously).
Another electronic gremlin involves the backup camera. This was a widespread issue that led to a massive recall. The image would often flicker, go black, or show a blue screen. Ford eventually released a hardware replacement for the camera module and a software update to the Image Processing Module.
From a DIY perspective, many interior rattles can be traced back to the panoramic sunroof or the A-pillar trim. Applying a small amount of Krytox lubricant to the sunroof seals can stop the annoying squeaks that often plague these vehicles during temperature changes. Checking the fuse box for loose relays is also a quick fix for intermittent electrical issues.
Recalls and TSBs: What Every Owner Should Know
Because the 2020 was a redesign year, it has a high number of Technical Service Bulletins (TSBs). A TSB is different from a recall; it is a guide for mechanics on how to fix common, non-safety-related issues. Staying on top of these is the secret to maintaining high 2020 ford explorer reliability over time.
One notable TSB involves a whistling noise from the side mirrors at highway speeds. The fix is a simple application of foam tape inside the mirror housing. Another involves the “deep sleep mode” where the battery drains prematurely. This is usually caused by a faulty Body Control Module (BCM) software calibration that keeps the vehicle’s computers awake longer than necessary.
Always use your VIN on the NHTSA website to check for open recalls. The most critical for the 2020 model include the rearview camera failure, the driveshaft disconnect, and potential fuel line leaks on certain engine configurations. Getting these handled at a dealership is free and essential for your safety.
DIY Maintenance Schedule for Longevity
If you want your Explorer to last 200,000 miles, do not follow the “Normal” maintenance schedule in the owner’s manual. That schedule is designed for the lowest cost of ownership during the warranty period. For true 2020 ford explorer reliability, follow a “Severe Weather/Towing” schedule.
Change your engine oil every 5,000 miles using a full synthetic 5W-30. Even though the Intelligent Oil-Life Monitor might say you can go 10,000 miles, shorter intervals prevent the timing chain wear and turbocharger clogging common in EcoBoost engines. Also, replace your engine air filter every 15,000 miles, especially if you drive on dusty trails.
Don’t forget the PTU (Power Transfer Unit) fluid if you have an Intelligent 4WD model. The PTU sits near the exhaust and gets very hot, which cooks the fluid. While Ford says it’s a sealed unit, many enthusiasts use a suction pump to change the fluid every 30,000 miles to prevent expensive gear failure.
Frequently Asked Questions About 2020 Ford Explorer Reliability
Is the 2020 Ford Explorer a reliable used car?
It is moderately reliable.
