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 2017 model year.

“My 2017 Ford Fusion with 77,000 miles was running poorly. I noticed coolant reservoir was empty with no visible leaks. Took it to a Ford dealership and was told coolant was leaking into cylinders. I was told to fix the car they would have to replace the engine. Had I not noticed the coolant issue and the engine died while driving in highway traffic, my safety, as well as the safety of others would have been at risk.”

“Coolant intrusion into cylinder 3 on 2.0L ecoboost motor. The original motor was replaced under factory warranty at roughly 58000 miles. The replacement motor now has roughly 18,000 miles and 18 months on it and the same problem is occurring. Ford is refusing to stand behind their product and cover the repair/replacement of the defective replacement long block.”

Should you keep driving it?

This page can't tell you that. 1 of 338 reports involved a crash and 2 people were hurt. 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.
