Ford Expedition 3.5L EcoBoost: A Mechanic's Unfiltered Look Beyond the Hype

Alright, folks, let's talk about the Ford Expedition 3.5L EcoBoost, specifically the newer models from 2020 onwards. I'm not here to sell you anything; I'm here to give you the straight goods based on what I've seen in my shop. This beast is a full-size SUV, often chosen by families needing space and towing capacity. But let's cut through the marketing BS and see what it's really like to own one.

Real-World Fuel Consumption: Ford might tell you one thing, but real life is different. Expect to see around 14-18 L/100km in combined driving. If you're heavy on the pedal or doing a lot of city driving, that number can easily climb to 20 L/100km or more. Towing will also significantly impact fuel economy. Don't expect hybrid-like numbers from this big engine, it likes to drink fuel. The 10-speed transmission is good but it doesn't magically make this SUV a fuel sipper.

Common Problems (From a Mechanic's Perspective): Now, let's get to the nitty-gritty. In my shop, I've seen a few recurring issues with the 3.5L EcoBoost in the Expedition:

Turbocharger Issues: The turbos themselves can be prone to leaks and sometimes failures, especially if the oil changes have been neglected. They are complex and expensive to replace. Carbon buildup on the intake valves is also a common problem in this direct injection engine, which can reduce performance and fuel economy.
Cooling System Concerns: I've seen a number of water pumps failing prematurely, as well as coolant leaks. Overheating can cause serious damage, so keep an eye on your temperature gauge.
Transmission Problems: The 10-speed transmission is complex and sometimes has shifting issues, especially at lower speeds. Some have experienced harsh shifts and even complete transmission failure. Check for any unusual noises or slipping.
Electrical Gremlins: Like many modern cars, the Expedition has its share of electrical problems. I've seen issues with the infotainment system, sensors, and even the power liftgate. These can be tricky and time-consuming to diagnose.
Suspension Wear: The weight of this SUV takes a toll on the suspension components. Expect to replace shocks, struts, and bushings more often than on a smaller vehicle.

Maintenance Costs: Owning a Ford Expedition 3.5L EcoBoost isn't cheap. Here's a rough idea of what to expect:

Oil Changes: Expect to pay around $100-$150 for a full synthetic oil change, which is recommended for this engine. It uses a specific type of oil that might not be available at your local quick lube shop.
Brake Jobs: A full brake job, including pads and rotors, can easily cost $600-$1000 per axle. The Expedition is heavy, so it goes through brakes faster than a smaller car.
Tire Replacements: Large SUV tires are pricey. Expect to pay $1500-$2500 for a set of four, depending on the brand and type.
Timing Chain Replacement: The 3.5L EcoBoost uses a timing chain, which should last a long time, but if you have issues with the chain tensioners, or guides you will be looking at a $2000-$3000 bill.
Turbocharger Replacement: If you are unlucky, turbo replacement can cost anywhere from $2500 to $4000 per turbo.

These are just estimates, and prices vary depending on your location and the shop you use. Don't expect cheap repairs with this car.

Hidden Costs: There are some hidden costs that you might not think about:

Special Tools: Some repairs on the 3.5L EcoBoost require specialized tools that most backyard mechanics won't have. This means you'll be relying on a qualified technician.
Premium Fuel: While it can run on regular fuel, Ford recommends premium fuel for optimal performance, which adds to your fuel costs.
Diagnostic Time: Electrical issues, and transmission problems can be tricky to diagnose, which can quickly rack up your repair bill.
Large Size: The size of the vehicle can make some maintenance tasks more difficult and time consuming, which will increase the cost of labor.

Overall Reliability: Here's the truth: the newer Ford Expedition 3.5L EcoBoost isn't the most reliable vehicle out there. I've seen too many issues with turbos, cooling systems, and transmissions. It's not a lemon, but it's not a Toyota either. This car requires diligent maintenance and you should be ready for some unexpected repairs. The complexity of the engine and transmission means more things can go wrong.

Total Cost of Ownership: This is not a cheap vehicle to own. Between the fuel costs, maintenance, repairs, and insurance, you'll be spending a significant amount of money. This is definitely an expensive car to own. In Canada, insurance costs can be high for large SUVs, especially in urban areas, and the price of fuel is not cheap. Don't forget about winter tires, which are a must in many parts of Canada and are another added cost.

Resale Value: The Expedition holds its value reasonably well, especially if it's well-maintained. It's a popular vehicle for families and those needing towing capacity, so there's usually a decent market for them. You shouldn't have a lot of issues selling it, but expect it to depreciate like any other car. However, high mileage or a poor maintenance history will reduce its value.

Tips for Prospective Buyers: If you're still considering a Ford Expedition 3.5L EcoBoost, here's some advice:

Get a Pre-Purchase Inspection: Always get a thorough pre-purchase inspection by a trusted mechanic. This can help you identify potential problems before you buy.
Check the Service History: Look for a vehicle with a complete service history. This shows that the previous owner cared for the car.
Test Drive Thoroughly: Test drive the vehicle in different conditions. Pay attention to any unusual noises or vibrations.
Check for Leaks: Check for any signs of leaks, especially around the engine, transmission, and cooling system.
Be Wary of Low Prices: If the price seems too good to be true, it probably is. It could indicate a vehicle with hidden problems.
Don't Rush the Decision: Take your time and do your research. Don't be pressured into buying something you're not comfortable with.

Alternatives: If you need a large SUV but are concerned about the Expedition's reliability and cost, you might consider a Toyota Sequoia. It is more reliable and has better resale value, but it will cost more. The Chevrolet Tahoe or GMC Yukon are other options, but they have similar issues with reliability to the Expedition.

Conclusion: The Ford Expedition 3.5L EcoBoost is a capable SUV with lots of space and power. However, it's not without its problems. It's not the most reliable vehicle, and it can be expensive to own and maintain. If you're okay with that, and you're prepared to spend the money and time for maintenance, then go for it. But if you're looking for a reliable, low-maintenance SUV, there are better options out there. Don't let the marketing hype fool you, this car is not for everybody.
