NHTSA summary

On February 21, 2013, the Office of Defects Investigations (ODI) opened Preliminary Evaluation PE13-003 to investigate allegations of electronic throttle body (ETB) failures resulting in sudden reduction of engine power in model year (MY) 2009-2013 Ford Escape, Fusion, Mariner and Milan vehicles. During this investigation, Ford identified a condition in subject vehicles equipped with 2.5L and 3.0L engines that may result in a sudden reduction of engine power.According to Ford, the ETB internal motor contacts may develop a high resistance material buildup condition on the commutator, resulting in intermittent electrical connectivity and reduced engine power. When this condition occurs, the Malfunction Indicator Lamp (MIL) or Wrench light will illuminate and the vehicle may enter a limited limp home mode.Ford?s trade name for the feature is Failure Mode Effects Management (FMEM) mode.In this mode, engine power and vehicle speed are reduced, while full function of the power steering, power braking, lighting, and climate control systems are maintained.ODI?s complaint analysis indicate that the predominant failure mode involved reduced motive power associated with the limited limp home mode with engine speeds limited to approximately 900 RPM. Analysis of warranty claims provided by Ford identified 59,807 claims related to ETB replacements and approximately 50 percent of claims are associated with diagnostic trouble codes (DTC) P2111, Throttle Body Stuck Open, and P2112, Throttle B

None of these investigations covers the 2015 model year.

What owners wrote

“Car began leaking coolant, overheating, smoking (white smoke) and misfiring on cylinder #3. Based on my research, this is an issue Ford knows about due to it being a defect in the design, yet I'm being told I have to pay to replace the engine. We replaced the spark plugs, coils, and nothing helped. We took it to a mechanic and were told we need an entire engine replacement and it won't be covered by Ford.”

“I got an engine temperature warning, then I noticed the coolant reservoir was empty. I filled it back up and everything went back to normal. I was driving down the interstate when the check engine light came on. I had a few misfires and was able to make it back to a dealership, who then diagnosed the vehicle and said it coolant intrusion due to an engine block leak. Charging over $9000 in repairs”

“Coolant leaking into cylinder 2, misfire (P0302), overheating, and white smoke from exhaust. Mechanic diagnosed potential head gasket or coolant intrusion issue. Vehicle is out of warranty. This seems related to known issues on EcoBoost engines, including TSB 19-2208 for later models, but no recall exists for the 2015 model. Major safety concern and potential engine failure”

“Coolant intrusion into cylinders of engine. Coolant leak into the cylinders can lead to corrosion, misfires, engine failure, and even potential car fires. Local ford mechanic confirmed thus was the issue and that he's personally seen SEVERAL others. No warning lights”

Should you keep driving it?

This page can't tell you that. 1 of 68 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
