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 2018 model year.

“Block cracked internally inside cylinder number 2 causing a misfire, white smoke on start up, coolant lose, and overheating. Problem is called coolant intrusion. Safety is at risk is the car dies on the interstate. It has a check engine light for misfire on cylinder 2. Ford is aware of this problem but says my vin is not affected by this problem even though I have this problem.”

“Vehicleâs engine was misfiring for a while before check engine light came on. Showing cylinder 2 misfiring codes when scanned. The first dealership replaced the spark plugs, didnât fix the issue. The next dealership said I have coolant intrusion and need to replace engine.”

“I have a 2018 ford fusion 2.0L ecoboost with around 77k miles and started to see coolant loss with no visible signs in engine bay or below.car, rough start with error P0316 and occasional misfire. White smoke comes from exhaust on start sometimes. Also have to fill coolant every other day or so. It looks as coolant intrusion issue very common with these engines.”

Should you keep driving it?

This page can't tell you that. 0 of 66 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.
