The Jeep Cherokee and Ford Explorer have long been two of the most recognizable nameplates in the SUV segment. Both have loyal followings and decades of production history, but they cater to slightly different buyer priorities. The Cherokee carries a reputation for off-road capability and rugged styling, while the Explorer targets families seeking a spacious, comfortable daily driver. However, when prospective owners compare these vehicles, engine problems and long-term reliability often become decisive factors. This detailed comparison examines the most common powertrain issues reported for each model, analyzes reliability data from major consumer sources, and walks through what shoppers should know before buying a used example.

Jeep Cherokee: Background and Market Position

The Jeep Cherokee name dates back to 1974, originally appearing as a full-size SUV built on the SJ platform. The model evolved through several generations, including the popular XJ (1984–2001), the more car-like KL (2014–2023), and the current generation that continues production in some markets. Throughout its lifecycle, the Cherokee has been praised for its off-road prowess—especially models equipped with the Trail Rated badge and the selectable four-wheel-drive systems—but has also accumulated a mixed record on reliability. Independent surveys from sources such as Consumer Reports often place the Cherokee below average for predicted reliability, especially in powertrain and electrical categories.

Common Engine Problems in Jeep Cherokee Models

Oil Leaks from Rear Main Seal and Valve Cover Gaskets

A frequently reported issue across multiple Cherokee generations involves oil leaks originating from the rear main seal and the valve cover gasket. The rear main seal sits at the back of the engine where the crankshaft exits the block; when it fails, oil drips onto the transmission bell housing and can eventually reach the exhaust system, producing a burning smell. Valve cover gaskets degrade over time due to heat cycles, allowing oil to seep onto the top of the engine. Both repairs are labor-intensive, particularly the rear main seal, which requires removing the transmission or at least supporting it. Owners of 2014–2021 Cherokees with the 2.4L Tigershark engine have lodged numerous complaints on forums and at the National Highway Traffic Safety Administration (NHTSA).

Engine Stalling and Hesitation

Stalling events—sometimes occurring at low speeds or when coming to a stop—have been reported across several model years of the Cherokee. The cause is often traced to faulty camshaft or crankshaft position sensors, a failing throttle body, or fuel delivery problems related to the high-pressure fuel pump. In the 2014–2016 models, a software issue in the engine control module also contributed to hesitation and intermittent stalling. Dealers released several powertrain control module (PCM) updates over the years, but not all vehicles received them before sale. For used Cherokee buyers, verifying that all relevant software recalls have been applied is a key step.

Transmission Roughness and Delayed Shifts

Although technically not an engine problem, the Cherokee's nine-speed automatic transmission—introduced in 2014—has generated a high volume of complaints that directly affect the driving experience. Reports of hard shifting, hesitation to engage gears, and sudden jerking during acceleration are common. In severe cases, the transmission may fail entirely, requiring a rebuild or replacement at a cost of several thousand dollars. The 2.4L engine is frequently paired with this transmission, and the combination has been cited in class-action lawsuits. Later model years (2020+) saw improvements, but earlier examples still carry a heightened risk. CarComplaints.com rates the 2014 Cherokee as having the most overall complaints, many tied to the drivetrain.

Reliability Ratings for Jeep Cherokee

J.D. Power and Consumer Reports consistently rank the Jeep Cherokee below the segment average for dependability. The 2018 model year saw an improvement in initial quality, but long-term reliability remained inconsistent. The 2.0L turbocharged engine introduced in 2019 has fewer reported issues to date, though sample sizes are smaller. Overall, if you prioritize a rugged SUV with genuine off-road capability and are willing to accept a higher risk of repairs, the Cherokee can still be a valid choice—but careful model year selection is critical.

Ford Explorer: Background and Market Position

Since its debut in 1990, the Ford Explorer has been one of America's best-selling SUVs. It evolved from a truck-based body-on-frame design to a unibody platform in 2011, and then to a rear-wheel-drive-based platform in 2020. The Explorer is engineered for comfort, cargo space, and family-oriented features, with far less emphasis on off-road ability than the Cherokee. Most buyers use it for commuting, road trips, and light towing. Its reliability record is generally better than the Cherokee's, but it still has known problem areas—especially in models equipped with Ford’s turbocharged EcoBoost engines.

Common Engine Problems in Ford Explorer Models

EcoBoost Carbon Buildup and Timing Chain Wear

The 2.3L and 3.5L EcoBoost engines, found in many Explorer models from 2011 onward, use direct fuel injection without port injection assist. This design allows fuel to bypass the intake valves, leading to carbon deposits accumulating on the valves over time. Symptoms include reduced power, rough idle, and decreased fuel economy. A walnut-blast cleaning service can restore performance, but it's an added maintenance cost that conventional port-injection engines do not require. Additionally, the timing chain on some early 3.5L EcoBoost engines (2011–2015) has been known to stretch prematurely, triggering the tensioner to fail and—in worst cases—causing interference damage. Ford extended warranties on certain components, but out-of-pocket repairs can exceed $2,000.

Transmission Failure in 2011–2019 Models

The 6F35 six-speed automatic transmission equips many Explorers from 2011–2019 and has a history of premature failure. Owners report harsh shifts, slipping, loss of reverse gear, and transmission overheating. The root cause is often attributed to weak internal seals or a faulty valve body. In many examples, the transmission requires replacement at 70,000–100,000 miles. Later models (2020+) switched to a 10-speed automatic, which has generally fared better but still has isolated complaints of shuddering. Consumer Reports rates the Explorer's transmission reliability as below average for several model years, especially 2013 and 2016.

Cooling System Weaknesses: Water Pump and Radiator Issues

Another notable problem on the 3.5L V6 (non-EcoBoost) and 3.5L EcoBoost engines is the water pump. On these engines, the water pump is mounted internally and driven by the timing chain. When the pump fails, coolant can leak into the engine oil, causing catastrophic bearing failure. Replacing the water pump requires removing the timing chain cover—a labor-intensive job often costing $1,500 to $2,500. Many owners have reported early failures at around 50,000–60,000 miles. Radiator leaks, while less catastrophic, have also been noted, particularly on Explorers operated in hotter climates.

Reliability Ratings for Ford Explorer

Overall, the Ford Explorer tends to score higher than the Jeep Cherokee in reliability studies, but it is not class-leading. The 2018–2020 model years showed improvement in powertrain reliability, but infotainment and electrical issues persist. J.D. Power's vehicle dependability study often places the Explorer near the middle of the pack among three-row SUVs. For shoppers seeking the most trouble-free experience, the 2019–2021 model years with the naturally aspirated 3.3L V6 (available on base trims) appear to have the fewest engine-related complaints. The EcoBoost options offer more power but come with the higher maintenance costs described above.

Comparative Analysis: Engine Problems and Reliability

Which SUV Has More Frequent Engine Issues?

According to aggregated complaint data from the NHTSA and independent sites, the Jeep Cherokee generates a higher complaint rate per 1,000 vehicles than the Ford Explorer for engine-related problems over the past decade. The Cherokee’s oil leaks and transmission roughness are widespread, especially in the 2014–2017 model years. The Explorer, while not immune, has fewer reports of engine stalling and failure but is more likely to suffer from expensive internal engine components (water pump, timing chain) that require major disassembly to repair. In terms of severity, a failed water pump on the Explorer can destroy the engine, while a Cherokee oil leak is more of an inconvenience (though it can lead to secondary problems if ignored).

Repair and Maintenance Costs Comparison

RepairPal estimates average annual maintenance costs for the Jeep Cherokee at about $640, slightly above the segment average. The Ford Explorer averages around $700 per year. However, these averages mask outliers: a transmission replacement on a Cherokee can run $3,500–$4,500, while a Ford water pump job costs $1,500–$2,500. Both vehicles have expensive potential failures, but the Explorer’s major repairs tend to be more predictable (water pump will eventually fail), whereas the Cherokee’s transmission problems can strike without warning.

Model Year Sweet Spots

Jeep Cherokee: The most reliable years are generally considered 2018–2020, after the 2.4L engine received updated software and the nine-speed transmission was refined. Avoid 2014–2016 models unless you have a thorough service history and are prepared for possible transmission service. The 2021–2023 models with the 2.0L turbo have improved reported reliability, but early data is still limited.

Ford Explorer: The 2019–2022 models (fifth generation, facelifted) offer a good balance of modern features and reliability, particularly with the naturally aspirated 3.3L V6 on the base trim. For older models, the 2017–2018 years are better than 2011–2016, but still carry EcoBoost carbon buildup and water pump risks. The 2020+ sixth-generation models have received mixed reviews; the 10-speed transmission shudders have been addressed by recalls, but electrical glitches are still reported.

Resale Value and Depreciation

Resale values for both vehicles are influenced by reliability perceptions. The Ford Explorer holds its value better than the Cherokee, especially in the first five years. According to Kelley Blue Book, the Explorer typically retains about 50% of its MSRP after five years, while the Cherokee often drops to 40–45%. The Cherokee’s lower initial price can offset some of that depreciation, but for long-term ownership, the Explorer may provide a lower total cost of ownership due to fewer high-cost repairs—provided you select a model with a less problematic engine.

What to Look for When Buying Used

If you are considering a used Jeep Cherokee or Ford Explorer, follow these practical inspection steps:

  • Check for leaks: Look for red or brown fluid under the engine and transmission. On the Cherokee, check the rear of the valley between engine and transmission for oil seepage. On the Explorer, inspect the front cover area for signs of coolant from a failing water pump.
  • Test the transmission: Take an extended test drive including stop-and-go traffic, highway merging, and uphill grades. Feel for harsh 1–2 shifts or delayed engagement. On the Cherokee, pay special attention to slow-speed maneuvering (parking lots).
  • Review repair history: Ask for receipts showing transmission fluid changes and any water pump or timing chain work. For the Explorer, ask if the intake valves have been cleaned. For the Cherokee, check for PCM updates and rear main seal replacements.
  • Verify recalls: Use the NHTSA VIN lookup tool to confirm all safety and powertrain recalls have been completed. Both vehicles have had multiple campaigns over the years.
  • Consider a pre-purchase inspection: Have an independent mechanic familiar with these models perform a compression test and a thorough drivetrain evaluation. Cost $150–$300, it’s money well spent.

Conclusion

Both the Jeep Cherokee and Ford Explorer have well-documented engine problems that potential owners should understand before buying. The Cherokee offers a more rugged, off-road-capable platform but suffers from a higher frequency of driveline complaints—especially its nine-speed transmission and oil leaks. The Ford Explorer provides a more refined on-road experience and generally better reliability ratings, but its EcoBoost engines can require expensive carbon buildup and water pump repairs that catch owners off guard.

Your final choice depends on what you value most. If you need genuine four-wheel-drive capability for light off-roading or live in an area with harsh winters, the Cherokee’s Trail Rated heritage may outweigh its reliability concerns. If your primary use is family transport, commuting, and road-trip comfort, the Explorer’s roomier interior and stronger resale value make it the safer bet—especially if you avoid the most problematic engine options. In either case, a thorough pre-purchase inspection and careful model year selection are your best defenses against costly surprises down the road.
