The Ford 1.6L EcoBoost is one of the more dangerous engine problems in this database — not because the failure rate is the highest, but because the failure mode is fire. The cylinder head on this engine has a known weakness in the casting around the exhaust port. As the engine heat-cycles over time, the head cracks. Coolant from the cooling jacket leaks through the crack and into either the cylinder (where it gets burned with the fuel mixture, producing telltale white exhaust smoke and a slowly disappearing coolant reservoir) or directly onto the exhaust manifold (where it can flash to steam and, in a non-zero number of cases, ignite). Ford has issued multiple recalls covering different aspects of this problem over the years. The fixes have evolved — early remedies were heat shields and software updates, later fixes involved actual head replacement on affected VINs. NHTSA opened formal investigations into engine fires on these vehicles. If you're shopping a 2013-2016 Escape or Fusion or a 2014-2018 Fiesta with the 1.6 EcoBoost, the very first thing to do is run the VIN through both Ford's recall lookup and NHTSA's recall lookup. If any of the open recalls aren't completed, walk away or factor the risk in heavily. If they're all completed, you're in safer territory but still want a careful inspection — pop the oil cap and look for coolant emulsion, check the coolant reservoir for low level, look for white smoke at startup. The 1.6 was discontinued and Ford moved to a 1.5 EcoBoost in most of the affected applications. The 1.5 isn't perfect either, but the catastrophic head cracking pattern that defined the 1.6 is much rarer.

My car set a code , and the engine misfired. I took all the necessary steps, but the code reappeared. I have Car Shield, and they are saying its cracked block but refuse to replace the head gasket. My mechanic believes it's the head gasket, so a cracked block seems common in these cars, as does a…
The transmission has completely gone out. On this car model, there isn't a dip stick for the owner to check transmission fluid levels. While pulling out of a parking space the car hesitated on going into first gear and then jerked really hard before continuing to move. While still in the parking…
The contact owns a 2014 Ford Escape. The contact stated while the vehicle was parked, the contact shifted into reverse; however, the rearview camera intermittently was upside down, flashed on and off, and then became dark. The vehicle failed to return to normal operation. No warning light was…
The contact owns a 2016 Ford Escape. The contact stated that the heater failed to operate with the check engine warning light was intermittently flashing on the instrument panel. The vehicle was taken to a dealer where it was discovered that coolant was leaking into cylinder #3. The manufacturer…
Steering stopped working during drive home. It is now at my house. Safety was impacted because it became problematic during the drive. I had an independent mechanic evaluate the car today, he stated that this make and model of a vehicle is known to have this problem, and diagnosed it with a need to…
Driver side sun visor fell off hinge and was dangling from wire that powers vanity mirror. Plastic part holding it up seems to have fallen off. No screws there. Had to hold it in one hand until I could pull over and figure out how to stow it.
Common questions
What vehicles use the Ford 1.6L EcoBoost?
The Ford 1.6L EcoBoost was used across 18 model-year combinations from 2013-2018. The most-affected applications are listed in ranked order on this page. Each entry links to the full reliability profile for that specific year/model combination.
What are the most common problems with the 1.6L EcoBoost?
The dominant complaint patterns are: cylinder head cracking allowing coolant intrusion; coolant loss with no visible leak (burns through engine); engine fires from coolant contact with hot exhaust components. Across all affected vehicles in our database, 14,121 owner complaints have been filed with NHTSA, plus 47 active recall campaigns.
How serious are the 1.6L EcoBoost problems?
Severity varies by model and year. Across the family, NHTSA records show 10 crash-related complaints, 6 fire incidents, and 8 injuries. Critical recalls on file: 0. Click into any specific vehicle below to see severity tied to that exact application.
Should I avoid vehicles with the 1.6L EcoBoost?
Not automatically. The complaint data points to specific failure patterns that are well-understood, and many of them have known fixes — sometimes covered by extended warranty, sometimes by class-action settlement, sometimes by aftermarket service procedures. The right call depends on the specific vehicle, its maintenance history, and whether the known issues have been addressed already. Read the editorial above and click into the specific vehicle you're considering for the full picture.
Is an extended warranty worth it on a vehicle with the 1.6L EcoBoost?
On engines with documented expensive failure modes, an extended service contract can pay for itself in one repair. Average independent-shop repair on an engine of this scope runs $2,500-$8,000 depending on what fails. A quality service contract is $1,800-$3,500 over 3 years. The math depends on the specific vehicle's complaint pattern, age, and miles. Use the calculator on the specific vehicle's page for a real estimate.
Engine fires aren't normal. If your 1.6 EcoBoost has had any unexplained coolant loss or any history of warning lights related to overheating, get it looked at by a Ford dealer that can read the recall completion history on your specific VIN. The recall work is free. The alternative is much worse.
