How Reliable Is The Ford Explorer – A Real-World Mechanic’S Guide
The Ford Explorer is a staple of the American road, offering a blend of family utility and light off-road capability. While modern generations have seen significant improvements in technology and fuel economy, potential buyers should be aware of specific transmission and cooling system vulnerabilities that vary by model year.
Choosing a mid-size SUV is a significant investment, and you likely want a vehicle that can handle the daily commute, weekend camping trips, and everything in between without constant trips to the shop. You might be wondering if this iconic Ford can truly go the distance or if it will become a permanent resident on your driveway jack stands.
In this guide, we will break down the mechanical reality of this SUV, focusing on the common failures, the “bulletproof” engines, and the years you should probably skip. By the time you finish reading, you will have a clear understanding of how reliable is the ford explorer and whether it fits your specific driving needs.
We are going to look at the transition from front-wheel-drive platforms back to rear-wheel-drive architectures and how those changes impacted overall durability. From the dreaded internal water pump issues to the latest 10-speed transmission shifts, we are covering it all from a technician’s perspective.
The Evolution of the Platform: How Reliable is the Ford Explorer Across Generations?
To understand the current state of reliability, we have to look at the two most recent iterations of this vehicle. The fifth generation (2011–2019) moved to a unibody, front-wheel-drive-based platform, which changed the driving dynamics and maintenance requirements significantly compared to the old truck-based models.
The sixth generation (2020–Present) returned to a rear-wheel-drive bias, aimed at improving towing and performance. However, this transition was not without its “teething” problems, especially in the 2020 launch year, which saw numerous recalls and software glitches that frustrated many early adopters.
When asking how reliable is the ford explorer, you must differentiate between these platforms. A 2018 model is a very different machine than a 2021 model, and their failure points are unique to their specific engineering designs and component suppliers.
The Fifth Generation (2011–2019)
This generation is widely available on the used market. It is generally considered “average” in terms of reliability, but it suffers from a few “ticking time bombs” that every DIY mechanic should know. The most notorious is the internal water pump on the 3.5L V6 engine.
Unlike most cars where the water pump is driven by an external belt, this pump is driven by the timing chain. If the seal fails, coolant leaks directly into the engine oil, which can lead to total engine failure if not caught immediately. This is a 10-12 hour labor job to fix proactively.
The Sixth Generation (2020–Present)
The newer models offer impressive power from the 2.3L EcoBoost and the 3.0L twin-turbo V6. While the 2020 models had a rough start, the 2022 and 2023 models have shown improved build quality. The focus here is more on electronic modules and transmission shift logic rather than catastrophic mechanical failure.
Understanding Common Mechanical Pitfalls
Every vehicle has its “Achilles heel,” and the Explorer is no different. For those who like to do their own wrenching, understanding these common issues helps you perform better pre-purchase inspections. Most issues center around the drivetrain and cooling systems.
One frequent complaint across multiple years involves the suspension bushings. The rear subframe bushings are known to crack or squeak over time, especially if you frequently drive on salted winter roads or take the vehicle on washboard dirt trails during camping excursions.
Another area to monitor is the turbocharger system on EcoBoost models. While these engines are powerful, they are sensitive to oil quality. Carbon buildup on the intake valves and turbo oil feed line clogs can occur if you don’t stick to a strict 5,000-mile synthetic oil change interval.
Transmission Troubles: The 6F55 and 10R80
The older 6-speed transmissions were relatively stout but could suffer from “harsher” shifts as they aged. However, the newer 10-speed 10R80 transmission has been a point of contention for many owners. It is designed for efficiency, but some units experience “hunting” for gears or erratic shifting.
If you are test-driving a newer Explorer, pay close attention to the 3rd-to-4th gear shift and the downshift when coming to a stop. Often, a PCM (Powertrain Control Module) software flash can fix these issues, but sometimes it indicates internal valve body wear that requires professional repair.
Cooling System Integrity
Beyond the internal water pump mentioned earlier, keep an eye on the plastic coolant “Y-pipes” and connectors. Over time, the heat cycles of the engine make these plastic parts brittle. Replacing them with aftermarket aluminum versions is a common pro-tip for long-term owners to prevent sudden overheating.
how reliable is the ford explorer in Off-Road and Towing Scenarios?
Many owners choose the Explorer for its 5,000 to 5,600-pound towing capacity. When pushed to these limits, how reliable is the ford explorer compared to a body-on-frame SUV? The answer depends largely on how you manage heat and weight distribution.
For towing, the rear-wheel-drive-based 2020+ models are superior. They handle the tongue weight better and provide more stable tracking. However, if you plan on towing regularly, installing an auxiliary transmission cooler (if not already equipped) is one of the best things you can do for the longevity of your clutches.
Off-road, the Explorer is a “soft-roader.” The Timberline trim offers better ground clearance and underbody protection, but the unibody construction means you shouldn’t be rock crawling. It excels on forest service roads and beach sand, provided you don’t overheat the Intelligent 4WD system’s center coupling.
The Importance of Fluid Management
If you are taking your Explorer off-road or using it for heavy hauling, you cannot follow the “lifetime fluid” intervals suggested by the manual. Change your PTU (Power Transfer Unit) fluid every 30,000 miles. The PTU sits near the exhaust and the fluid can cook, leading to gear failure.
Braking and Safety Systems
When descending steep grades with a trailer, the Explorer’s brake-based torque vectoring and hill descent control work hard. This can lead to faster brake pad wear. Always use heavy-duty ceramic pads and high-quality rotors to ensure you have the stopping power needed for mountain passes.
The Best and Worst Years to Buy
If you are in the market for a used model, your choice of year is the single biggest factor in your ownership experience. Not all Explorers are created equal. Some years are legendary for their durability, while others are best left on the dealer lot.
The 2011-2013 models are often avoided due to early electric power steering failures and the aforementioned water pump issues. Similarly, the 2016 model year saw a spike in transmission complaints. The 2020 model, being the first of a new generation, is often flagged for electrical gremlins and trim quality issues.
Conversely, the 2018 and 2019 models are considered the “pinnacle” of the 5th generation. Ford had sorted out most of the production kinks by then. For the current generation, the 2022 and newer models are showing much better initial quality scores and fewer trips to the dealership for warranty work.
- Avoid: 2011, 2013, 2016, 2020.
- Best Bets: 2018, 2019, 2022, 2023.
- Pro Tip: Always check the VIN for outstanding recalls, especially regarding the rear camera and driveshaft bolts on newer models.
Maintenance Checklist for Maximum Longevity
To ensure your Explorer hits the 200,000-mile mark, you need to be more proactive than the average driver. Reliability is a partnership between the machine’s engineering and the owner’s diligence. Following a strict maintenance schedule is the only way to mitigate the known weak points.
- Oil Changes: Every 5,000 miles using full synthetic 5W-30 (or the weight specified on your oil cap).
- PTU Service: Change the gear oil in the Power Transfer Unit every 30k miles to prevent “sludging.”
- Coolant Inspection: Check for any signs of “milkiness” in the oil or “sweet smells” in the exhaust, which indicate water pump seal failure.
- Transmission Drain and Fill: Do not “flush” the system; simply drain and refill the fluid every 50k miles to keep the 10-speed shifting smoothly.
- Spark Plugs: On EcoBoost engines, gaps can widen quickly under boost. Replace plugs every 40k-50k miles for optimal fuel economy and power.
By staying ahead of these items, you can often avoid the major repair bills that give some people a negative view of the platform. A well-maintained Explorer is a dependable partner for any road trip or DIY project.
