As is the case with any mass-produced item, problems are kind of inevitable. The more of something that is produced, the more room for error. This is the case in point when looking at Ford EcoBoost Engine Problems.

But what if there is an enforced recall on a product?
Well, that’s a pretty good indication that there may be something more serious brewing.
However, I want to make it very clear that I am not here to make any claims about how Ford does business. Ford is one of the largest of all automobile companies in the world and one of the oldest. Henry Ford, who the company is named after, built his first vehicle in 1896 and went on to mass-produce the first genuinely global automobile – the Model T.
But it is next to impossible for a company as big as Ford to get every single piece of machinery correct every single time. And that, my friends, is where we have ended up today.
Ford EcoBoost Engine Recalls
In 2018, following an investigation by the English national broadcaster, the BBC, Ford was forced to recall two of the engines from the EcoBoost lineup. During this investigation, the BBC revealed that they had come across literally hundreds of complaints from owners of both the 1.0-liter and the 1.6-liter models.
And the problem was?
Well, to put it simply, fire. Car engines catching on fire, to be more precise. Not a good sign for any motoring company.
Not all these complaints referred to fire issues, though. General overheating of the engine was another common complaint. Not as severe, but still bad enough for the engines to be recalled.
Ford released a recall statement showing that at least 45000 1.0-liter 3 cylinder EcoBoost engines produced between 2011 to 2013 had been fitted with a faulty nylon cooling pipe. At high temperatures, these pipes were known to fail, sometimes cracking open completely.
The problem with the 1.6- liter 3 cylinder Ecoboost engine was different but also produced overheating and fire issues. The problem was localized heating causing the engine cylinder head itself to crack, which in some cases caused pressurized oils to spray forth and catch alight.
These issues were mostly reported as happening in Great Britain, although some cars in the United States also spontaneously combusted, just not as many. So if you’re in the USA, then there is certainly less to worry about.
Is that it for recalls, then?
Nope! There have been other recalls which did affect us stateside. The Ford Escape 2015 – 2018 models and the Ford Fusion 2013 – 2019 models have been recalled. If you are worried about your particular model, the best bet is to do a quick search and see if there has been a recall concerning your vehicle.
Don’t run away just yet, though; we’re only getting started!
The Ecoboost range of engines has had multiple incarnations over the years, so let’s take a look at the entire range and see what other common issues may be handy to know about. This is even if they weren’t recalled, which most of these have not been. I’ll go in ascending order in terms of engine size, so feel free to scroll down until you find the engine you want to know more about.
The first batter up is the…
The 1.0-Liter 3 Cylinder EcoBoost
This is one of the engines I have already mentioned, so I won’t go into great detail and repeat myself. What I did not say is that this is a direct-injection engine. Since the fuel is directly injected (duh), the intake valves can become clogged with carbon.
If this happens…
Clogged intakes can lead to valve and valve seat damage, as well as a loss of power.
The 1.5-Liter 3 Cylinder EcoBoost
I am happy to report that the 1.5-Liter 3 Cylinder EcoBoost engine – which replaced the faulty 1.6-liter – has had a smooth sail since its introduction. No significant flaws have been reported thus far.
The 1.6-Liter 3 Cylinder EcoBoost
As with the 1.0-liter, I covered this engine already in the previous section. I will elaborate a little further for this one, though, if you have been reading speedily and missed it.
The main engine compartment (the engine head) had an overheating issue which could cause it to crack open and leak or in spray pressurized oil. In some cases, this oil could overheat to the point of catching on fire and turning the car into a dragon.
But, there was also an additional issue…
Coolant leaks plagued this engine which could become a costly issue for the owner.
Thankfully, Ford decided to discontinue production on these engines and replace them with the 1.5-liter.
The 2.0-Liter 3 Cylinder EcoBoost
I first saw the 2.0-liter Ecoboost hit the market in 2010, with its second-gen being introduced in 2015. This engine was used in multiple models such as Ford Edge, Everest, Tornado, Lincoln MKZ, and the Bronco Sport, to name a few.
A great engine in many ways, but…
Thanks to an easily clogging fuel filter, the low-pressure fuel pump is known to have issues at times. The most significant problems are the fact that the exhaust manifold is prone to cracking. Plus, the turbocharger control valve can fail more often than it should.
The 2.3-Liter 3 Cylinder EcoBoost
As with the 1.0-liter variant…
The 2.3-liter engine is known to have intake valve issues, with the intakes becoming clogged with carbon. This can cause power generation issues as well as valve seat damage.
The head gasket is also known to fail on occasion, which is a very pricey fix.
The 2.7-Liter 3 Cylinder EcoBoost
Having only been released in 2018, the 2.7-liter Ecoboost has a pretty clean record so far.
The 3.5-Liter 3 Cylinder EcoBoost
Ahhhh, the 3.5-liter Ecoboost engine. This engine is the real reason why I ended up researching this topic, as I am the proud owner of a failing Ford F-150.
There is more than one issue that can plague this engine so let’s jump into it…
As this engine is used more regularly in work vehicles, they are more often subjected to hard labor. This can lead to multiple problems.
Timing Chain Issues
I have said it before, and I’ll say it again. The most important thing you can do to keep your car running smoothly is to stay up to date with the servicing schedule. If oil changes are neglected, it can lead to a bunch of problems, but the most prevalent is timing chain issues.
The 3.5-liter engine is turbocharged, which results in the oil being under high stress. Old oil can cause significant timing chain damage, as well as to the tensioner and guides.
If your 3.5-liter Ecoboost engine is exhibiting some misfire issues or an intermittent loss of power (especially during long journeys), then there may be some condensation trapped in the intercooler.
The good news is…
There are a few ways to fix this issue. Repositioning the air deflector from the top of the intercooler to the bottom helps to vaporize this condensation.
The other option is to drill a small hole in the bottom of the intercooler, which will help the condensation drain out. We do not recommend this, though, as it can lead to costly oil leaks.
If you notice either blue or white smoke coming out of the exhaust, you most likely have an issue with the PCV (positive crankshaft valve).
Ford has released a totally redesigned valve cover adapter to combat this problem.
As with some of the other Ecoboost models, the intake valves on the 3.5-liter engine can become clogged with carbon. Always use the highest quality fuel to ensure your best chance at avoiding this problem.

Wrapping Up on Ford EcoBoost Engine Problems
So, as we can see, there are several issues that can plague the range of Ford EcoBoost engines. That is not to say that these are bad engines, though, not at all. Every mass-produced engine will come away with some problems, and for the most part, I have been extremely happy with my Ford F-150.
Hopefully, this has brought a little light to whatever is happening to your car. Remember to regularly service your vehicle to have the best chance at avoiding engine problems with the Ford EcoBoost altogether.
Enjoy your vehicle and your rides!
