What Years Of Ford Explorer To Avoid – Skip These Models To Save
Buying a used Ford Explorer can be a great move for families and off-roaders, but certain model years are notorious for catastrophic transmission and engine failures. This guide identifies the specific years from 2002 to 2020 that you should skip to avoid expensive repairs and safety risks.
Choosing a used SUV can feel like navigating a minefield, especially with a legacy nameplate like the Ford Explorer. You want a vehicle that handles the school run and the trailhead with equal ease, not one that lives on a mechanic’s lift.
I understand the frustration of sinking hard-earned money into a vehicle that develops a “death whine” or a “coolant leak” just weeks after purchase. This article provides a clear roadmap to help you identify what years of ford explorer to avoid while highlighting the gems that offer the best reliability.
By the end of this guide, you will know exactly which generations have the most complaints and what specific mechanical red flags to look for during a test drive. Let’s dive into the history of this iconic SUV and separate the workhorses from the lemons.
The Troubled Third Generation (2002–2005)
The third generation of the Ford Explorer marked a significant redesign, but it also introduced some of the most persistent mechanical headaches in automotive history. If you are looking at early 2000s models, you need to be extremely cautious.
The Infamous 5R55W Transmission
The 2002 Ford Explorer holds the unenviable title of having the most owner complaints of any year. The primary culprit is the 5R55W automatic transmission, which is known for premature failure, often occurring before the 100,000-mile mark.
Common symptoms include a blinking “O/D Off” light, harsh shifting, and a complete loss of reverse gear. These issues usually stem from worn solenoid blocks or bore wear in the transmission case itself. Fixing this often requires a full rebuild, which can cost more than the vehicle’s current market value.
The Rear Liftgate Crack
If you look at almost any 2002–2005 Explorer, you might notice a vertical crack in the plastic panel just below the rear window. This is so common it has been dubbed the “Explorer Crack.” While this is a cosmetic issue, it demonstrates a lack of material durability during these production years. Moisture can seep into the crack, potentially causing rust on the metal latch components over time. It is a minor annoyance compared to the transmission, but it affects resale value significantly.
Wheel Bearing and Hub Failures
Owners of these years frequently report loud humming or growling noises coming from the wheels. The rear wheel bearings on the 2002–2005 models tend to fail early and often.
Replacing these isn’t a simple DIY job for everyone, as the bearings are often pressed into the knuckle. For a weekend mechanic, this requires a hydraulic press or purchasing the entire hub assembly, which adds to the maintenance cost of an older vehicle.
A Detailed Look at what years of ford explorer to avoid and Why
When researching what years of ford explorer to avoid, the 2006 model year stands out as a transitional period that didn’t quite fix the previous generation’s sins. While Ford attempted to address the transmission issues, they introduced new cooling system flaws.
The 2006 Radiator and Cooling Woes
The 2006 Explorer is notorious for radiator leaks and plastic thermostat housing failures. The 4.0L V6 engine uses a plastic housing that becomes brittle over time due to heat cycles.
If the thermostat housing cracks, you lose coolant rapidly, leading to immediate engine overheating. As an experienced DIYer knows, overheating a modern engine even once can warp the cylinder heads, turning a $50 plastic part replacement into a $2,500 engine job.
Spark Plug Ejection (4.6L V8)
The 2006 model also featured the 3-valve 4.6L V8 engine, which is famous for two things: spark plugs that break off in the head during removal and spark plugs that eject themselves while driving. Both scenarios are a nightmare for owners.
If you are buying a 2006 V8, ask the seller if the spark plugs have been replaced recently. If they haven’t, you might be looking at a very stressful afternoon in the garage with a broken spark plug extraction tool and a lot of patience.
Continued Transmission Hesitation
Even with the updated 6-speed transmission in the V8 models, owners reported significant “shift flare” or hesitation. This is often caused by software calibration issues or early wear in the torque converter, making the driving experience jerky and unpredictable.
The Fifth Generation (2011–2016) and the Internal Water Pump
The shift to a car-based unibody platform in 2011 modernized the Explorer, but it brought about a specific engineering choice that still haunts owners today. This era is a critical part of knowing what years of ford explorer to avoid if you want to avoid a total engine loss.
The 3.5L Cyclone V6 Water Pump Disaster
The 3.5L Ti-VCT V6 engine used in the 2011–2016 models features an internal water pump driven by the timing chain. This is a major design flaw for long-term reliability.
When the water pump’s internal seal fails, it doesn’t just leak on the ground; it leaks directly into the engine oil pan. This creates a “chocolate milk” sludge that destroys the engine bearings in a matter of miles. Because the pump is behind the timing cover, replacing it as preventative maintenance can cost $1,500 to $2,000 in labor alone.
Electric Power Assisted Steering (EPAS) Failure
The 2011–2013 models are prone to sudden power steering failure. Unlike old hydraulic systems that get heavy gradually, the EPAS system can shut down instantly, making the vehicle extremely difficult to steer at low speeds.
Ford issued recalls for some units, but many vehicles on the used market still suffer from sensor failures within the steering rack. Replacing the entire steering rack is the only permanent fix, which is a high-ticket item that requires specialized programming tools.
Carbon Monoxide Infiltration
One of the most serious safety concerns with the 2011–2017 models is the report of exhaust fumes entering the cabin. This was particularly prevalent during hard acceleration or when using the air conditioning in recirculation mode.
Ford released multiple TSBs (Technical Service Bulletins) to seal the rear of the vehicle, but many owners still report the smell of sulfur or exhaust. If you test drive an Explorer from these years, bring a portable CO detector or pay close attention to any unusual smells in the cabin.
The 2020 Model Year: The New Generation Growing Pains
The 2020 Ford Explorer represented a return to a rear-wheel-drive platform, which enthusiasts loved. However, the launch was plagued by manufacturing defects and software glitches that make it a year to avoid for now.
Massive Recall Counts
The 2020 model year was hit with over a dozen recalls shortly after its release. These ranged from minor trim issues to major safety concerns like the parking brake failing to engage or the side-impact sensors not working correctly.
Many of these issues were caused by a rushed production start at the Chicago Assembly Plant. While most recalls have likely been performed by now, a vehicle with such a rocky start often has “gremlins” that pop up later in its life cycle.
Transmission Programming Issues
The 10-speed automatic transmission in the 2020 model was criticized for harsh shifting and “hunting” for gears. While Ford has released several software updates to smooth out the shifting logic, some units still feel unrefined compared to the 2021 and 2022 models.
If you are looking at a 2020 model, ensure that all PCM (Powertrain Control Module) and TCM (Transmission Control Module) updates have been applied. A jerky transmission on a newer vehicle is a sign that the hardware may have been stressed by poor software management.
Which Ford Explorer Years Are Actually Reliable?
After discussing what years of ford explorer to avoid, it is only fair to point out the years that have proven to be reliable over the long haul. If you want the best Explorer experience, look at these specific timeframes.
- 2010 Ford Explorer: This was the final year of the fourth generation. Ford had finally ironed out the transmission and cooling issues, making it one of the most robust used SUVs you can buy.
- 2017–2019 Ford Explorer: By the end of the fifth generation, Ford had improved the water pump seals and refined the EPAS system. These years offer modern tech with much better reliability than the 2011–2013 versions.
- 2022–Present Ford Explorer: After the disastrous 2020 launch, Ford made significant quality control improvements. The 2022 and newer models are showing much better initial quality and fewer mechanical complaints.
For those looking for a project or a budget off-roader, the late 90s (1996–2001) models with the 5.0L V8 are legendary for their durability. They are simple to work on and parts are incredibly cheap at any local auto parts store.
DIY Inspection Checklist for Used Explorers
If you find a great deal on an Explorer that falls into one of the “risky” years, you don’t necessarily have to walk away, but you must do your homework. Use this checklist to protect your wallet.
- Check the Oil Cap: Open the oil filler cap and look for a milky, light-brown residue. This is a sign of coolant mixing with oil, indicating a failing internal water pump on 3.5L engines.
- Listen to the Transmission: During the test drive, pay attention to the 2-3 shift. If the RPMs “flare” or spike between gears, the transmission is on its way out.
- Test the Steering: Turn the wheel lock-to-lock while the vehicle is stationary. Listen for any whining or “notchy” feeling that could indicate a failing electric steering rack.
- Exhaust Smell: Drive the car with the windows up and the AC on. Accelerate hard on an on-ramp and smell for any exhaust fumes entering the cabin.
- Scan for Codes: Even if the Check Engine Light isn’t on, use a basic OBD-II scanner to check for “pending codes.” This can reveal intermittent misfires or transmission pressure issues that the seller may have cleared.
Always remember that a Pre-Purchase Inspection (PPI) by a trusted mechanic is worth the $100-$150 investment. They can put the vehicle on a lift and check for frame rust or leaking seals that you can’t see from the driveway.
Frequently Asked Questions About what years of ford explorer to avoid
Is the 2002 Ford Explorer really that bad?
Yes, statistically and mechanically, the 2002 model is considered one of the worst SUVs ever made due to its high rate of transmission failure. It is best to avoid this year entirely, regardless of the price.
What is the “water pump issue” everyone talks about?
On the 3.5L V6 engines (2011–2019), the water pump is located inside the engine behind the timing chain. If it leaks, it dumps coolant into the oil, which can destroy the engine. It is a very expensive repair because of the labor involved.
Are the newer 2020+ Ford Explorers safe to buy?
The 2020 model had many recalls and quality issues. However, the 2021 and 2022 models have seen significant improvements. If you want a sixth-generation Explorer, aim for a 2022 or newer model to avoid the initial production bugs.
Which Ford Explorer engine is the most reliable?
The 4.6L V8 (found in older models) and the 2.3L EcoBoost (found in newer models) are generally considered more reliable than the 3.5L V6 with the internal water pump. The 5.0L V8 from the late 90s is the most “bulletproof” of them all.
Final Thoughts on Choosing the Right Explorer
Navigating the used car market requires a balance of research and intuition. While the Ford Explorer is a versatile and capable vehicle, the “bad years” can quickly turn your dream of weekend adventures into a financial nightmare.
