Ford’s EcoBoost engines are known for their power and fuel efficiency. Therefore, this is a popular choice in many Ford vehicles. However, these engines do have some common problems.
This guide will explain the most common issues with different EcoBoost engine types, like the 2.7L, 3.5L, and 1.5L. Knowing about these issues can prevent you from surprises and costly repairs.
Ford EcoBoost Engine Problems
1. Ford 2.7 EcoBoost Engine Problems
This is known for its impressive performance, but it has some issues that affect its reliability:
Carbon Buildup on Intake Valves
Direct fuel injection causes carbon deposits on intake valves. It causes engine performance issues like weaker performance, increased fuel consumption, and rough idling. To fix this issue, regularly clean valves with walnut blasting or fuel additives. It can reduce CO deposits.
Oil Pan Leaks
The early models of the 2.7L engine had oil pans which are made of plastic with poor sealings. This caused low oil levels and oil accumulating under the car. To fix this issue, replace the seal around the gasket or switch to a metal oil pan.
2. 3.5 Ford EcoBoost Engine Problems
It is a powerful and versatile engine. However, it also has some issues.
Timing Chain Stretch
Drivers face timing chain wear if they do not change engine oil on time. This can lead to several problems, such as:
Not changing the oil on time or skipping oil changes can make the timing chain wear out faster than it should. This can lead to several problems, like:
- The engine produces grinding sounds.
- The vehicle may feel slow and do not perform well.
- Check the engine light and it will inform you about the problem.
To fix this problem, replace the timing chain because a damaged chain can cause more serious engine problems.
Turbocharger Failure
Low or dirty oil can damage the turbocharger. This can cause a loss of power, screaming sounds, and too much exhaust smoke. To prevent this, check your oil regularly and change oil on time.

Coolant Leaks
It happened due to head gasket or radiator issues. It can cause engine overheating, steam from under the windshield, or frequent refills. To fix this, first analyze the problem and then replace damaged gaskets or radiators.
Spark Plug and Ignition Coil Issues
Spark plugs and ignition coils weaken rapidly due to engine design. This can lead to problems like engine failure, rough idling, and slow acceleration. Regular replacements can help you to prevent more serious issues.
4. Ford 1.5 EcoBoost Engine Problems
This engine is used in cars like the Ford Escape. It is fuel-efficient. However, it has the following common issues:
Overheating and Coolant Intrusion
The engine block design is responsible for coolant leaks into the cylinders. This can cause white smoke from the exhaust, a rough engine idle, or a power loss. In order to fix it, replace the engine block, which can be expensive. Check your coolant levels regularly to identify the problem early.
Engine Stalling
Engine stalling can happen because of problems with the fuel injectors or throttle body. Its signs include losing power suddenly or having trouble starting the car. To fix it, check the fuel system and clean or replace any damaged parts.

Coolant System Failures
Coolant system failures due to coolant leaks into the engine. This causes overheating, a sweet smell inside the car, and significant coolant loss. To fix this, regularly clean the system and replace or repair the engine head gasket.
Fuel Efficiency Decline
The buildup of CO reduces fuel efficiency. This leads to lower MPG and slower performance. This can be solved by doing routine maintenance. For example, replacing the air filters and cleaning the intake system.
Preventing EcoBoost Engine Problems
You can reduce these problems by taking the following steps:
- Oil Changes: Try to change the oil on time. It avoids waste buildup and keeps the engine running smoothly.
- Coolant Checks: It is an important part of the engine. It keeps your engine from overheating. Leakage in the coolant system can cause serious problems like engine overheating or damage. Therefore, check the coolant levels daily. Visit professional mechanics, If you notice any leakage under the car or around the engine.
- Turbo Maintenance: The turbocharger needs proper lubrication to work effectively. Improper lubrication can cause damage, and lead you to expensive repairs. To prevent this problem, check the oil levels regularly.
- Carbon Buildup Prevention: To prevent this, use high-quality fuel, which burns cleaner and leaves fewer deposits. You can also use professional cleaning services like walnut blasting. This removes CO buildup and keeps your engine running smoothly.
Conclusion
Ford's EcoBoost engines are known for their great performance and fuel efficiency. However, like any other engine, they also come with a set of common issues. Knowing about these issues will help you to avoid expensive repairs.
