Common Problems With The Ford Eco-boost Engine

While Ford’s EcoBoost engine is a great choice, it has a few issues. Unfortunately, Ford hasn’t responded to this issue, and you may be required to make repairs. Here are some concerns you should be aware of if you’re planning to buy a Ford equipped with EcoBoost engine: EcoBoost engine:

Engine Knocking And Pinging:

The most frequent issue is the loud knocking sound at starting up. It usually occurs during cold starts, when the engine starts to knock for a few seconds before warming up. A sound that is heard in cold engines isn’t unusual. However, the behavior of those EcoBoost engines is unusual, given that it is still happening following a complete warm-up and at high or moderate speed.

A few owners had reported that their EcoBoost-powered vehicle pings and stops were powering up while driving when speed was high. The pinging occurs most often when driving uphill. This is because the EcoBoost engines use insufficient fuel for the turbocharger’s boost. If this occurs, it’s crucial to move to an appropriate location and switch off your engine as quickly as you can.

Oil Consumption Issues:

It is known that the Ford EcoBoost engine produces an excessive amount of oil. Although some instances can be expected, it’s essential to ask your mechanic if your oil consumption is within limits.

According to some reports, low oil levels can cause severe engine damage, especially when the vehicle is shut off for a period of time. It is because the oil can’t be drained out of the engine and can overheat, leading to extreme damage to the various elements in the engine.


Engine Failure:

Another major issue that owners have complained about is the random failure of engines. There are occasions when the engine does not start after turning it off the engine for a short time. Although low oil levels can be the cause, it can also happen with vehicles with many miles.

Transmission Issues:

Ford EcoBoost engines were found to have transmission issues similar to their predecessors.

The transmission may stop working entirely or be difficult to shift in moving from a stop. Because the Ford EcoBoost engine has less power than its predecessors, It is essential to drive in the right direction.

Poor Fuel Economy:

Another complaint Ford owners have about EcoBoost cars is their low fuel efficiency. This is the case with most EcoBoost cars, even those with automatic transmissions. The issue with fuel efficiency usually happens when the car is in use for long periods.

You should check the performance of your car using the owner’s guidebook since low fuel efficiency is usually because of driver errors and not due to design defects.

Rough Idle:

Ford EcoBoost cars are characterized by a rougher idle than their traditional engine counterparts. The difference isn’t noticeable in everyday driving but when the vehicle is stationary or in traffic. The issue with rough idle is due to EcoBoost technology, which relies on direct injection, not a port injection.

Noisy Turbocharger:

A few customers have expressed concern about sound emanating out of the turbocharger. The turbochargers found on Ford’s EcoBoost engines emit a loud whine. It cannot be very pleasant for specific drivers, but it doesn’t alter the vehicle’s performance or driving experience.

Defective Air Box:

There is a rumor that specific Ford EcoBoost models have a malfunctioning air box. It is because the original manufacturer of the equipment could not get the necessary clearances to allow adequate airflow to the engine. Airbox malfunctions can result in several problems, like hesitation or inadequate acceleration.


Engine Cracking:

The EcoBoost engines are vulnerable to cracks in the engine, which can cause engine failure. It is usually due to the high pressures associated with direct injection. Ford has released a service bulletin on this issue. Check the status of your vehicle’s warranty before any work is done on the engine.

Transmission Shudder:

Ford EcoBoost transmissions can experience a thump or shake while shifting gears. The torque converter causes the reason for this. However, there have been problems with the transmission, and repairs covered under warranty didn’t prevent any future shakes.

Turbocharger Seal Failure:

According to several owners, the owners of their Ford EcoBoost vehicles suffered from problems with the turbocharger seal. After conducting oil changes on their vehicles, it was found that the engine consumed more than three quarts of oil throughout.

Engine Noise:

There is a rumor the Ford EcoBoost engines can make a peculiar sound. The engine sounds typically occur when the vehicle is idle, and it gets louder as the load increases, which causes the car to vibrate excessively. The issue can be due to some causes, like poor gaskets in the oil or damaged motor mounts.

It is the EcoBoost technology. It is beneficial because it increases horsepower but does not sacrifice fuel efficiency. But it doesn’t mean you shouldn’t push your engine beyond its limits. Please don’t overload your vehicle, as it could result in internal damage to your engine.

Use Adequate Engine Oil:

Ford suggests using 5W-20 engine oil to run your EcoBoost vehicle. However, numerous owners have reported that their cars use too much oil.

Inadequately filling the crankcase with oil or applying the wrong viscosity could cause serious harm to your engine. If you need more clarification, the best option is to choose the less-viscosity oil. The oil capacity for the 2.0L and the 2.7L engines is 5 quarts and four quarters, respectively.

Avoid Racing The Engine:

Ford’s EcoBoost technology is more powerful than the traditional V6 engines and V8 ones, but it is important not to push the engine to the limit. The engine’s racing can result in severe damage and significantly shorten its lifespan.

Use A Cold Air Intake:

Installing a cold-air intake system in the EcoBoost can let it breathe more easily and increase performance and efficiency. However, you should not install a cool air intake when the car is not designed to be an installed version from the factory.

Regular Oil Changes:

To ensure proper operation and the proper operation EcoBoost engine, make sure you frequently change the oil. Also, you should adhere to the recommended oil specifications set by Ford for your specific car’s year/mileage.

Avoid Forced Induction:

Ford EcoBoost engines come with turbochargers, which increase power without sacrificing fuel efficiency. But, it is best to avoid fitting a turbo-kit in your vehicle because it could stress the engine.

Upgrade The Engine With Ford Performance Parts:

Ford offers a range of performance components to their EcoBoost series of engines that enhance their strength and endurance. It is recommended to upgrade your engine by using these parts if you wish to maximize the power of this engine.

Ford utilizes its 2.0L four-cylinder Ford EcoBoost engine in many vehicles. A few of these are Ford’s Ford S-Max, Galaxy, Mondeo, Explorer, Edge, and Range Rover Evoque, as well as other models.

It is a top-rated engine. There were two versions of this engine. The first version was manufactured from 2010 until 2015, and then a brand new one had to be developed in 2015 as Ford needed to develop its motor. Before that, the 2.0 EcoBoost was an homage to the Mazda L. Mazda L engine.

Do you have some 2.0L Ford EcoBoost problems? There are many. It’s shocking to discover that such a widely used engine has a few essential design defects. These are the typical issues that could be encountered when using a 2.0L EcoBoost engine: 2.0L Ford EcoBoost engine:


Cracking of the exhaust manifold can be the most frequent issue for all generations of 2.0L EcoBoost engines. It is because the exhaust gas temperature within this engine may rise to extreme temperatures, particularly when traveling or towing.

The continual heat cycles of the engine cause it to expand and expand the stainless exhaust manifold frequently. In the end, hairline cracks appear on the manifold’s exhaust.

If the manifold for exhaust is damaged and the exhaust gases escape from the manifold rather than exiting the tips of the exhaust. Not only is this harmful to the surroundings, but the engine will also lose all back pressure inside the system.

Your turbocharger must put in extra effort to reach normal power levels, which need back pressure to function effectively. If you’ve cracked your exhaust manifold, signs you’ll observe are:

  • A whistling sound emanated through the exhaust system.
  • Decreased performance.
  • The smell of exhaust fumes in the vehicle.

However, exhaust manifolds can be expensive to fix. The cost of replacing them can be up to $1,000. So if you plan on towing frequently, stay clear of this motor.


The solenoid for turbo boost control is a valve that controls how much boost the turbocharger produces. In addition, it regulates the wastegate that regulates the flow of exhaust gases into the turbo.

The greater the flow and the higher the flow, the speed at which the turbo spins and the more boost it can generate. If the solenoid is damaged and fails to function properly, it will be unable to shut and open the wastegate correctly. It means that the turbo will not be able to generate enough boost.

If, for instance, you place your foot on the floor, it will give you more boost because the foot pointing down indicates you’re seeking more power. However, if the solenoid’s condition is defective, it could not be able to open the wastegate in this case, and you’ll not get the boost you want.

Like any other vehicle component, the boost solenoid can wear out with time. But, in other vehicles equipped with turbochargers, the solenoid for boost usually is damaged after ten years.

Regarding the 2.0L EcoBoost, owners are saying that their boost solenoid breaks at the beginning of 50k miles. If it fails, you’ll observe diminished power and low engine efficiency, and an engine check warning light may be visible.

The solenoid for the boost control costs about fifty dollars for replacement. However, replacing it could be problematic in the absence of a professional. In addition, you’ll likely have to spend an additional $80 or so in labor costs.



The EcoBoost engine is powered by two pumps for fuel: the low-pressure fuel pump (LPFP) and the high-pressure fuel pump (HPFP). The HPFP’s job is to provide gasoline to injectors in turn, and the LPFP is used to remove gas from the tank and then deliver fuel to the HPFP.

The LPFP may become blocked in time, resulting in engine malfunctions and an incorrect mixture of air and fuel because there needs to be more fuel being supplied.

Remember that fuel pumps in other vehicles can also fail; however, this is a regular occurrence with this 2.0L EcoBoost engine.
