Ford Explorer Reliability: Best Years, Years to Avoid, Common Problems, Repair Costs & Lifespan

Is the Ford Explorer reliable? Which model years are the best used buys, and how long can an Explorer last?

The Ford Explorer can be a dependable, long-lasting SUV, particularly when you choose the right model year, engine, and drivetrain. Many well-maintained Explorers reach 200,000 miles, and some continue well beyond that. However, reliability varies between generations, and certain mechanical problems deserve attention before buying.

For buyers considering an older Explorer, the 2009–2010 models are attractive choices, particularly with the available 4.6-liter V8. Among newer models, the 2016–2019 Explorers offer a useful combination of comfort, features, and value, although engine and all-wheel-drive maintenance remain important.

The redesigned 2020–2022 Explorer introduced improved performance and technology, but its earliest model years experienced enough quality and drivetrain complaints to warrant additional inspection.

Ford Explorer Reliability Overview

Overall, Ford Explorer reliability is best described as average, with some generations and engine combinations performing better than others.

That's not necessarily a discouraging assessment. The Explorer has been a popular family SUV for decades, and many owners enjoy years of dependable service. Replacement parts are widely available, independent repair shops are familiar with the vehicle, and several Explorer engines are capable of substantial mileage.

The Explorer's strengths include a comfortable highway ride, generous passenger space, available three-row seating, and good towing capability when properly equipped. Later models also offer modern safety technology and strong performance.

The biggest difference between Explorer generations involves their underlying mechanical design.

The 2002–2010 models use traditional body-on-frame construction and offer naturally aspirated V6 and V8 engines. The 4.6-liter V8 is particularly appealing for long-term durability, while the 4.0-liter V6 requires more attention to its timing-chain system.

The 2011–2019 generation adopted a more car-like unibody design with front-wheel drive or available all-wheel drive. These Explorers offer improved comfort and efficiency, although the naturally aspirated 3.5-liter V6 has an internal water pump that can be expensive to replace. All-wheel-drive models also have a power transfer unit that deserves inspection.

For 2020, Ford returned to a rear-wheel-drive-based platform with newer turbocharged engines and a 10-speed automatic transmission. These vehicles offer excellent performance, but early examples experienced various quality, electronic, and drivetrain complaints.

These concerns should be kept in perspective. Not every Explorer experiences the problems associated with its generation, and a properly maintained example can be a very satisfying used SUV.

Bottom Line: The Explorer can be a good long-term purchase, but engine choice, maintenance history, and the condition of the individual vehicle matter more than its overall reliability reputation.

Ford Explorer Reliability at a Glance

• Overall Reliability: Average, with meaningful differences between generations
• Best Years: 2009–2010, 2016–2019, and 2022
• Years Requiring Extra Inspection: 2002–2005, 2011–2013, and 2020–2021
• Strong Older Engine Choice: 4.6-liter V8, particularly in well-maintained 2006–2010 models
• Most Important Inspection Areas: Engine, transmission, cooling system, and AWD components
• Expected Lifespan: Approximately 200,000–250,000 miles with excellent maintenance
• Maintenance Costs: Moderate, although certain major repairs can be expensive

Buyer Tip: When comparing used Explorers, identify the engine and drivetrain before making a decision. Two vehicles from the same model year can have different maintenance requirements and potential repair costs.

How Many Miles Can a Ford Explorer Last?

A properly maintained Ford Explorer can realistically reach 200,000 miles, and particularly well-maintained examples can exceed 250,000 miles.

Some Explorers have traveled 300,000 miles or more, although reaching that mileage economically depends on the engine, transmission, maintenance history, and repairs already performed.

For most buyers, 200,000 miles is a reasonable long-term expectation rather than a guarantee. The Explorer's ability to reach higher mileage depends on consistent maintenance and addressing problems before they become serious.

Regular engine oil changes are essential, but long-term owners should also pay attention to transmission fluid, coolant, differential fluids, transfer-case or power-transfer-unit maintenance where applicable, and suspension wear.

On older Explorers, the cost of accumulated repairs can eventually become more important than whether the engine itself is capable of running longer.

A high-mileage Explorer with complete service records and documented major repairs may be a better purchase than a lower-mileage example that has been neglected.

Bottom Line: A good Explorer can provide 200,000 miles or more of service. Reaching 250,000 miles is achievable with excellent maintenance, but the vehicle's condition and repair history become increasingly important as mileage rises.

What Are the Best Ford Explorer Model Years to Buy?

Several Explorer model years stand out as appealing used choices. The best one depends partly on whether you're looking for an older traditional SUV or a newer three-row family vehicle.

2009–2010 Ford Explorer

These are among the best choices for buyers interested in an older body-on-frame Explorer. They represent the final years of the fourth generation and benefited from several years of production refinement.

The available 4.6-liter V8 is especially appealing for buyers who prioritize durability and towing capability. Fuel economy isn't a strength, but a well-maintained V8 Explorer can offer excellent value.

2016–2017 Ford Explorer

These later fifth-generation models offer updated styling, modern features, and a comfortable family-oriented design.

They can be attractive used SUVs, particularly with a strong maintenance history. Buyers should still investigate the internal water-pump risk on applicable 3.5-liter V6 engines and the condition of the power transfer unit on all-wheel-drive models.

2018–2019 Ford Explorer

The final years of the fifth generation are among the more appealing choices for buyers wanting a relatively modern Explorer without moving into the completely redesigned 2020 model.

They offer a mature platform, good passenger comfort, and a useful selection of engines and equipment. As with earlier fifth-generation models, drivetrain condition remains important.

2022 Ford Explorer

The 2022 Explorer is worth considering for buyers interested in the newer rear-wheel-drive-based generation.

It benefited from additional production experience following the 2020 redesign. Nevertheless, transmission operation, electronics, maintenance records, and recall history should still be checked carefully.

Buyer Tip: Don't assume that a newer Explorer is automatically the better purchase. A well-maintained 2017 model with documented repairs can be preferable to a neglected 2020 or 2021.

What Ford Explorer Model Years Should You Avoid or Inspect More Carefully?

There are relatively few Explorer model years I'd automatically reject without an inspection. However, certain years have enough recognized concerns to justify additional caution.

• 2002–2005: Automatic transmission problems and expensive timing-chain repairs on the 4.0-liter V6 are important considerations. Rear wheel bearings and differential condition also deserve attention.
• 2011–2013: Early fifth-generation models have potential internal water-pump concerns on applicable 3.5-liter V6 engines, along with AWD power transfer unit, power-steering, and electronic issues.
• 2020–2021: Early sixth-generation vehicles experienced drivetrain, electronic, and quality complaints associated with the redesign. Transmission operation and recall history deserve particular attention.

These concerns don't mean every Explorer from these years is unreliable. Many provide dependable service, and a vehicle with excellent maintenance records and documented repairs may still be a worthwhile purchase.

I'd be particularly cautious about an inexpensive older Explorer with an uncertain transmission history, a 3.5-liter V6 showing unexplained coolant loss, or a newer Explorer with persistent shifting problems.

Bottom Line: Treat these years as requiring more careful evaluation rather than automatic rejection. The condition and maintenance history of the individual Explorer should determine whether it's a good buy.

Ford Explorer Reliability by Generation

The Explorer changed substantially during the years covered here. Engine choices, drivetrains, and even the vehicle's underlying construction differ between generations.

The following "common problems" are recognized or reported issues worth checking. They do not necessarily affect most Explorers, and many vehicles provide dependable service without experiencing them.

Third Generation: 2002–2005 Ford Explorer Reliability

The Explorer received a major redesign for 2002, introducing independent rear suspension and improved passenger comfort while retaining its traditional body-on-frame construction.

Two engines were available: a naturally aspirated 4.0-liter V6 and a 4.6-liter V8. Both can accumulate substantial mileage, but the V8 is generally the more appealing choice for buyers who prioritize long-term durability.

The 4.0-liter V6 uses a complicated timing-chain arrangement. Wear in the chain guides or tensioners can produce rattling noises, particularly during a cold start. Repairs can be labor-intensive because of the location of certain components.

Automatic transmission condition is another important consideration. Some owners have reported delayed engagement, harsh shifting, slipping, or transmission failure. A properly functioning transmission should engage smoothly and shift consistently during a thorough test drive.

Neither issue affects every Explorer, but both deserve attention because major repairs can be expensive relative to the value of these older vehicles.

Common Problems on 2002–2005 Ford Explorers

• Automatic transmission slipping, delayed engagement, or failure
• 4.0-liter V6 timing-chain guide and tensioner wear
• Rear wheel bearing failures
• Rear differential noise or wear
• Cracked rear liftgate trim panels
• HVAC blend-door and actuator problems
• Age-related cooling-system and suspension wear

When inspecting one of these Explorers, start the engine completely cold and listen for unusual timing-chain noise. Check transmission operation both cold and fully warmed up, and listen for wheel bearing or differential noise during the test drive.

The available 4.6-liter V8 avoids the 4.0-liter V6's complicated timing-chain arrangement and can be a worthwhile alternative, although fuel consumption is higher.

Buyer Tip: A clean, well-maintained V8 Explorer may be worth paying more for than a cheaper V6 model with an uncertain transmission or timing-chain history.

Bottom Line: The 2002–2005 Explorer can be an affordable used SUV, but transmission and V6 timing-chain concerns make a thorough inspection particularly important.

Fourth Generation: 2006–2010 Ford Explorer Reliability

Ford substantially updated the Explorer for 2006, improving its chassis, interior, safety equipment, and overall refinement.

The familiar 4.0-liter V6 remained available, along with an updated 4.6-liter V8. These Explorers retained traditional body-on-frame construction, making them attractive to buyers who appreciate the older SUV design and its towing capability.

The 4.6-liter V8 is particularly appealing. Beginning in 2006, Ford used a three-valve version paired with a six-speed automatic transmission. It provides strong performance and can accumulate substantial mileage when properly maintained.

Fuel economy is the obvious tradeoff, and the three-valve V8 has maintenance considerations of its own. Spark-plug servicing, for example, requires proper procedures because removal can be difficult on some engines.

The 4.0-liter V6 can also provide long service, but its timing-chain system remains a concern. Buyers should listen for unusual rattling and review the vehicle's maintenance history.

Common Problems on 2006–2010 Ford Explorers

• 4.0-liter V6 timing-chain guide and tensioner wear
• Transmission shifting problems on some higher-mileage vehicles
• Wheel bearing and suspension component wear
• Radiator and cooling-system leaks
• HVAC actuator failures
• Oil leaks and age-related electrical problems
• Spark-plug servicing complications on some 4.6-liter V8 engines

Later examples from 2009 and 2010 are especially appealing because they represent mature versions of this generation. A documented V8 model with a healthy transmission, sound cooling system, and well-maintained suspension can be an excellent used value.

As these vehicles age, corrosion also becomes increasingly important, particularly for Explorers that spent winters on salted roads.

Buyer Tip: For buyers who value durability and towing capability more than fuel economy, a well-maintained 2009 or 2010 Explorer with the 4.6-liter V8 deserves serious consideration.

Bottom Line: The final years of the fourth-generation Explorer are among the stronger older choices, particularly with the V8 and a thorough maintenance record.

Fifth Generation: 2011–2019 Ford Explorer Reliability

The 2011 Explorer represented a major change. Ford replaced the traditional body-on-frame layout with a unibody design offering front-wheel drive or available all-wheel drive.

The result was a more car-like three-row SUV with improved passenger comfort, better fuel economy, and significantly more modern technology.

Engine choices included a naturally aspirated 3.5-liter V6, turbocharged 2.0-liter and 2.3-liter EcoBoost four-cylinder engines, and a twin-turbocharged 3.5-liter EcoBoost V6 in performance-oriented models.

These Explorers can be comfortable, capable family SUVs, and many accumulate substantial mileage. However, a few drivetrain-specific concerns are important when choosing a used example.

The most significant involves the internally mounted water pump on certain 3.5-liter V6 engines. Unlike a conventional externally mounted pump, this design places the pump behind the engine's timing cover, making replacement labor-intensive.

More seriously, some failures can allow coolant to contaminate the engine oil, potentially causing severe engine damage if the vehicle continues operating.

This doesn't mean every 3.5-liter V6 Explorer will experience water-pump failure. However, the potential repair cost makes it important to investigate unexplained coolant loss, overheating history, or previous cooling-system repairs. Documentation showing that the pump has already been professionally replaced can be a positive factor.

The turbocharged four-cylinder engines use a different water-pump arrangement, so this particular internal-pump concern doesn't apply to every fifth-generation Explorer.

All-wheel-drive models also have a power transfer unit, commonly called the PTU, that sends power toward the rear wheels. Heat, lubricant deterioration, and leaks can contribute to wear or failure on some vehicles.

Warning signs may include fluid leakage, a burning or sulfur-like odor, or whining and grinding noises from the front drivetrain. Front-wheel-drive models do not have this AWD component.

Common Problems on 2011–2019 Ford Explorers

• Internal water-pump failure on applicable 3.5-liter V6 engines
• Power transfer unit leaks or failures on some AWD models
• Electronic power-steering problems on certain earlier vehicles
• Infotainment and MyFord Touch glitches
• Suspension and wheel bearing wear
• Turbocharger-related repairs on some high-mileage EcoBoost models
• Exhaust-like odors reported inside certain vehicles
• Rear suspension toe-link concerns on applicable recalled Explorers

Some owners have also reported exhaust-like odors entering the cabin, particularly during hard acceleration. Ford issued service guidance addressing body sealing and ventilation components on certain earlier fifth-generation vehicles.

An unresolved exhaust-like odor should be investigated before purchase. Carbon monoxide itself is odorless, so the presence or absence of a smell cannot establish whether carbon monoxide is entering the cabin.

Rear suspension condition deserves attention as well. Ford has recalled certain Explorers for rear toe-link concerns, including situations where a toe link could fracture. Buyers should check the specific vehicle identification number for open recalls and have the underbody inspected for corrosion.

The later 2016–2019 models are among the more appealing Explorers in this generation. They offer modern features, comfortable interiors, and several years of production refinement while retaining the generation's basic mechanical design.

Buyer Tip: On a 3.5-liter V6 Explorer, ask about water-pump replacement history. On an AWD model, have the PTU checked for leaks and unusual noises. These two inspections can be particularly valuable.

Bottom Line: The fifth-generation Explorer can be a very good used family SUV, especially in its later years. Understanding the engine and AWD maintenance requirements helps buyers make a more informed choice.

Sixth Generation: 2020–2022 Ford Explorer Reliability

Ford completely redesigned the Explorer for 2020, returning to a rear-wheel-drive-based platform with available all-wheel drive.

The new design brought improved handling, strong towing capability, updated technology, and a modern selection of engines.

Most mainstream models use a 2.3-liter turbocharged EcoBoost four-cylinder, while higher-performance versions use a twin-turbocharged 3.0-liter EcoBoost V6. A hybrid powertrain was also available.

Both EcoBoost engines deliver impressive performance and can provide good service when properly maintained. Regular oil changes using the correct specification, cooling-system maintenance, and prompt attention to warning lights are especially important.

The redesigned Explorer also introduced 10-speed automatic transmissions. Some early vehicles experienced harsh shifting, delayed engagement, hesitation, or other transmission complaints.

Depending on the vehicle, causes can involve control-module calibration, valve-body operation, or internal transmission components. A test drive alone cannot determine which repair, if any, is needed.

During an inspection, check transmission operation both cold and fully warmed up. Pay attention to engagement from Park, low-speed shifts, acceleration, and downshifts.

Common Problems on 2020–2022 Ford Explorers

• Harsh or delayed automatic transmission shifts on some vehicles
• Electronic and software glitches
• Backup-camera and infotainment problems
• Early-production assembly and quality concerns
• Cooling-system and turbocharged-engine issues requiring diagnosis
• Recall-related repairs on certain vehicles
• Suspension and drivetrain wear on heavily used examples

The 2020 model experienced a more complicated launch than buyers might expect from a completely redesigned vehicle. Ford made continuing improvements during subsequent production, making later examples increasingly attractive.

That doesn't mean a 2020 or 2021 Explorer should automatically be avoided. A vehicle with completed recalls, documented service, and no unresolved drivetrain or electronic problems may still be a worthwhile purchase.

The 2022 model is an appealing option for buyers who want the newer Explorer design while benefiting from additional production experience.

Hybrid models deserve a knowledgeable inspection of their gasoline-electric drivetrain and high-voltage components, particularly if they have accumulated substantial mileage.

Buyer Tip: Before purchasing a 2020–2022 Explorer, review its recall history and any previous transmission or electronic repairs. Persistent shifting problems should be diagnosed rather than dismissed as normal operation.

Bottom Line: The sixth-generation Explorer offers strong performance, modern technology, and good family practicality. Later examples are especially worth considering, although individual vehicle condition remains important.

Ford Explorer Maintenance and Repair Costs

Routine Ford Explorer maintenance costs are generally moderate for a midsize SUV. Replacement parts are widely available, and most independent repair shops are familiar with the vehicle.

Regular maintenance includes oil changes, brakes, tires, cooling-system service, transmission maintenance, and suspension repairs as the vehicle ages.

The largest potential expenses involve major drivetrain repairs. Timing-chain work, internal water-pump replacement, automatic transmission repairs, and AWD power transfer unit failures can be costly.

These are broad estimates. Actual costs vary by model year, engine, location, labor rates, and parts required. Major repairs involving additional engine or transmission damage can cost considerably more.

The most economical Explorer to own is often the one that has been consistently maintained, even if its purchase price is somewhat higher.

Speaking of possible unexpected costs, before agreeing to a dealer's numbers, see which dealer fees are legitimate, which can be negotiated, and which can be avoided.

Used Ford Explorer Inspection Checklist

• Identify the engine and drivetrain, and review maintenance records.
• Check engine oil, coolant condition, and evidence of leaks.
• Listen for cold-start timing-chain noise on 4.0-liter V6 models.
• Investigate coolant loss on applicable 3.5-liter V6 engines and PTU condition on AWD vehicles.
• Test automatic shifting, steering, electronics, and suspension operation.
• Inspect the underbody for corrosion and check the NHTSA recall lookup.
• Arrange an independent pre-purchase inspection by a qualified mechanic.

Buyer Tip: An Explorer with documentation showing that an expensive known problem has already been professionally repaired may be a better purchase than a lower-mileage vehicle with an uncertain maintenance history.

Ford Explorer Alternatives to Consider

If you're shopping for a dependable midsize or three-row SUV, several alternatives deserve consideration.
