If you frequently tow, drive in dusty or extreme conditions, make short trips, or live in a cold climate, your 2020 Ford Explorer will benefit from a more rigorous maintenance schedule. This typically means accelerating many of the standard intervals:

• Oil and Filter Change: Every 3,000 – 5,000 miles.
• Tire Rotation: Every 5,000 miles.
• Cabin Air Filter: Every 10,000 – 15,000 miles or more frequently if driving in very dusty conditions.
• Engine Air Filter: Every 15,000 – 20,000 miles.
• Brake Fluid Flush: Every 2 years or 30,000 miles.
• Transmission Fluid Service: Every 30,000 – 60,000 miles, depending on the severity of use.
• Differential and Transfer Case Service: Every 30,000 – 60,000 miles.
• Accessory Drive Belt Inspection: Every 15,000 miles, replacement as needed.

Always consult your owner's manual for the most accurate severe-duty recommendations tailored to your specific vehicle and driving habits.

Known issues by mileage (this generation)

The 2020 Ford Explorer, being part of the sixth generation, has some reported issues that owners should be aware of, especially as mileage accumulates:

• Early Mileage (<30,000 miles): Some owners have reported issues with the 10-speed automatic transmission, including harsh shifts or hesitation. Electrical gremlins, such as infotainment system glitches or sensor malfunctions, have also been noted. Rear axle fluid leaks have been reported in some early models, so keep an eye out for any drips under the rear of the vehicle.
• Mid-Mileage (30,000 – 60,000 miles): Transmission issues may persist or become more pronounced if not addressed. Brake wear can be accelerated with aggressive driving or heavy loads, so regular inspection is vital. Suspension components, such as control arms or bushings, may start to show wear, leading to clunking noises or a less stable ride.
• Higher Mileage (>60,000 miles): Continuing monitoring of the transmission is important. Turbocharged engines (e.g., 2.3L EcoBoost, 3.0L EcoBoost) may begin to experience issues with turbocharger components or oil leaks if not properly maintained. The accessory drive belt should be replaced around 100,000 miles, but inspect it frequently for cracking or fraying as it gets older. Power steering components may also start to show signs of wear.

What you can DIY vs shop

Many maintenance tasks can be tackled by a competent DIYer, saving on labor costs. However, some services are best left to professional technicians due to specialized tools, knowledge, or safety concerns.

DIY-Friendly Tasks:

• Oil and Filter Change: With basic tools, a jack, jack stands, and proper disposal of used oil.
• Tire Rotation: Requires a jack, jack stands, and a torque wrench.
• Cabin Air Filter Replacement: Typically easy to access behind the glove compartment.
• Engine Air Filter Replacement: Usually a straightforward process of opening the airbox.
• Wiper Blade Replacement: Very easy to do yourself.
• Fluid Level Checks: Regularly checking engine oil, coolant, brake fluid, and washer fluid.

Shop Recommended Tasks:

• Brake Fluid Flush: Involves bleeding the brake lines, which can be tricky and requires careful attention to avoid air in the system.
• Transmission Fluid Service: Proper fluid type, level, and temperature are critical. Some modern transmissions require specific procedures.
• Differential and Transfer Case Service: Requires specific fluidoils and can be messy.
• Spark Plug Replacement: On some engines, spark plugs can be difficult to access, and improper installation can lead to costly damage.
• Coolant Flush: Proper disposal of coolant is important, and air pockets in the cooling system can cause overheating.
• Timing Chain Inspection/Replacement: A complex job requiring specialized tools and expertise. Improper work can lead to severe engine damage.
• Accessory Drive Belt Replacement: While seemingly simple, proper tensioning and routing are crucial to avoid squealing or premature wear.

When in doubt, always consult a professional. Safety should always be your top priority when performing any maintenance on your vehicle.
