Common Ford 1.0L EcoBoost engine problems and what to do If you have them

The EcoBoost is one of Ford’s most common engines. It was initially developed to be a high-power, environmentally friendly alternative to their other engines, and the EcoBoost is now installed in all new Fiesta and Focus models.

However, while you might experience better performance with the EcoBoost engine, it does have some drawbacks. In fact, many users have reported a host of problems with the EcoBoost. 

These are the top three most common EcoBoost engine problems and how you can solve them.

Carbon Build-up 

Engines with better fuel efficiency are notorious for their carbon build-up problems. Ford’s EcoBoost engine is no different, and the problem is made worse because it uses a direct injection-only system. As a result, carbon deposits can build up in the valves and threaten your engine’s performance. You’ll know your engine is suffering from carbon build-up if you notice poor acceleration or difficulty starting it, especially in the mornings when the engine is cold. 

If you know you have carbon build-up, you can use fine steel wool and solvents to clean the affected areas. However, this is only a short-term solution. 

 Low Fuel Pressure

The EcoBoost can deliver a very high MPG, but for this to happen, the engine must run at very high temperatures. This can cause a strain on engine parts, particularly the fuel injector pumps. Consequently, you may notice more frequent misfires or a knocking or whining sound coming from under the hood. If left untreated, it can cause more significant problems, like your engine completely shutting down periodically.

The solution to this issue is to replace the cam bucket completely. An authorised dealership should be able to do this for you, and the replacement may be free if you’re still covered by a warranty. 


The Ford EcoBoost 1.0L engine is also well known for its problems with overheating, which arises from the coolant system. This was the main reason that Ford recalled the EcoBoost engine in 2018. However, even now, the engine may struggle at high temperatures. In the worst cases, this can result in a complete engine shutdown. 

Overheating can be costly to repair. Leaks in the coolant system can cause severe damage to the entire engine system and may require an entirely new engine.
