You likely want to know if a used or new Explorer will be a dependable partner or a constant source of mechanical headaches. In this guide, we will break down the mechanical health of this iconic vehicle, identify the “golden years” for buyers, and reveal the maintenance secrets that keep these rigs on the road.
We will explore the common pitfalls of the EcoBoost engines, the nuances of the 10-speed transmission, and how the platform handles the stress of towing and light trails. By the end of this deep dive, you will have the expert knowledge needed to decide if are ford explorers reliable cars for your specific lifestyle and driving needs.
The Evolution of a Legend: Understanding Explorer Generations
To answer the question of reliability, we must first recognize that the Explorer has changed drastically over the last three decades. It transitioned from a truck-based, body-on-frame SUV to a more refined, car-like unibody construction starting in 2011.
The fifth generation (2011–2019) is where most buyers look for value, but it introduced complex front-wheel-drive biased platforms. The sixth generation (2020–Present) returned to a rear-wheel-drive architecture, promising better towing and dynamics but facing some initial “first-year” quality control hurdles.
When evaluating are ford explorers reliable cars, you have to look at the specific powertrain. A 2014 model with a naturally aspirated V6 is a very different beast compared to a 2020 model with a high-output 3.0L EcoBoost engine.
The Fifth Generation (2011–2019) Durability
This generation is generally considered a “workhorse” for many families. The 3.5L Ti-VCT Cyclone V6 is a robust engine, but it hides a significant design flaw that every DIY mechanic should know: the internal water pump.
If the water pump fails on this engine, it can leak coolant directly into the oil pan. This turns your engine oil into a “milkshake” consistency, which can lead to total engine failure if not caught immediately. Always check the dipstick for a milky residue when inspecting these models.
The Sixth Generation (2020–Present) Performance
The newest Explorers offer incredible power and technology. However, the 2020 model year was plagued by recalls and software glitches related to the new 10-speed transmission and infotainment system.
Ford has addressed most of these issues through Technical Service Bulletins (TSBs) and recalls. If you are buying a 2020 or newer, ensure the dealership has performed all necessary software flashes to the Transmission Control Module (TCM).
Are Ford Explorers Reliable Cars for Off-Roading and Towing?
For the off-road enthusiast, reliability isn’t just about the engine starting; it is about the 4WD system holding up under load. The modern Intelligent 4WD system in the Explorer is designed more for snow and gravel than for rock crawling.
The Transfer Case (or Power Transfer Unit – PTU) in older AWD models is known to run hot. If you plan on towing or hitting the trails, you must change the PTU fluid more frequently than the manual suggests to prevent the oil from “cooking” into a thick sludge.
Suspension components like the rear toe links have also been a point of contention. Heavy towing or frequent off-roading can accelerate wear on these parts, leading to alignment issues and uneven tire wear. Upgrading to heavy-duty aftermarket bushings can significantly improve long-term durability.
Towing Capacity and Cooling
Explorers are often rated to tow up to 5,600 lbs, which is impressive for their class. However, heat is the enemy of reliability when towing heavy loads through mountain passes.
If you plan to tow regularly, look for models equipped with the Heavy-Duty Trailer Tow Package. This includes upgraded cooling systems that prevent the engine and transmission from overheating, which is the leading cause of premature component failure.
The Terrain Management System
Ford’s Terrain Management System allows you to optimize the drivetrain for sand, mud, or snow. While the electronics are generally reliable, the wheel speed sensors can get fouled by mud and debris during off-roading.
If your “Service AWD” light pops up after a weekend in the dirt, it is often just a dirty sensor rather than a mechanical failure. A quick spray with a pressure washer around the wheel hubs can sometimes solve the problem.
Engine Reliability: EcoBoost vs. Naturally Aspirated
Ford offers a variety of engines, and your choice here determines your long-term maintenance costs. The 2.3L EcoBoost four-cylinder is surprisingly punchy and has proven to be quite reliable in the Explorer platform.
The 3.5L EcoBoost (found in the Sport and Platinum trims) offers exhilarating power but comes with more complexity. Twin turbochargers mean more heat and more potential leak points as the vehicle ages past 100,000 miles.
Carbon buildup on intake valves is a common issue for all Gasoline Direct Injection (GDI) engines. To maintain reliability, consider using a high-quality intake valve cleaner every 20,000 miles to keep the airflow path clear and prevent rough idling.
The Timing Chain Concern
On higher-mileage EcoBoost engines, the timing chain can stretch over time. This is often caused by extended oil change intervals that allow contaminants to wear down the chain links.
Listen for a “rattle” or “clatter” sound during a cold start. If you hear this, the timing chain tensioners or the chain itself may need replacement. To avoid this $2,000+ repair, stick to a 5,000-mile oil change interval using full synthetic oil.
Turbocharger Longevity
Turbochargers rely on clean oil for cooling and lubrication. If you drive your Explorer hard, let the engine idle for 30-60 seconds before shutting it off. This allows the oil to circulate and cool the turbo bearings, preventing “coking” or oil baking inside the lines.
A failing turbo will usually signal its demise with a high-pitched whine (the “dentist drill” sound) or blue smoke from the exhaust. Proactive oil maintenance is the best way to ensure these components last the life of the vehicle.
Common Mechanical Pitfalls and How to Avoid Them
Even though are ford explorers reliable cars overall, they have specific “quirks” that can catch an owner off guard. Being aware of these allows you to perform preventative maintenance before a breakdown occurs.
The 10-speed transmission (10R80) in newer models can sometimes exhibit harsh shifts or “gear hunting.” Most of the time, this is a software issue rather than a mechanical one. A “re-learn” procedure performed by a technician can often smooth out the shifting logic.
Electronic power steering racks have also been known to fail on the 2011–2015 models. This is a safety-critical component. If you notice the steering becoming heavy or hear a grinding noise when turning the wheel, have the rack inspected immediately.
The Infamous Water Pump Issue
As mentioned earlier, the internal water pump on the 3.5L V6 (non-turbo) is a major concern. If you are a DIYer, replacing this pump is a “engine-out” or very labor-intensive job because it is driven by the timing chain.
We recommend replacing the water pump proactively if you are already performing a timing chain service. It adds to the cost upfront but saves you from a catastrophic engine failure later on.
Carbon Buildup and GDI Issues
Direct injection provides great power, but because fuel doesn’t wash over the intake valves, carbon deposits form. This can lead to “misfires” and reduced fuel economy.
Installing a catch can (an oil-air separator) is a popular mod for Explorer owners. It captures oil vapors before they can enter the intake manifold, significantly slowing down the rate of carbon buildup on your valves.
The DIYer’s Guide to Maintaining an Explorer
One reason are ford explorers reliable cars for many owners is that they are relatively easy to work on for basic maintenance. Most filters and fluids are easily accessible, making it a great vehicle for the weekend mechanic.
Always use the specific fluids recommended in your owner’s manual. Ford vehicles are particularly sensitive to transmission fluid types. Using the wrong spec of Mercon fluid can lead to shift shudder and internal wear.
For those who live in the “Rust Belt,” the Explorer’s undercarriage is prone to corrosion on the rear subframe and brake lines. Applying a lanolin-based undercoating every autumn can add years to the life of the vehicle’s structural components.
