This investigation is prompted by NHTSA receiving 32 complaints about the electric vacuum assist pump allegedly failing in these trucks, which then causes the power braking assist to stop working. Drivers claim having no warning beforehand. There are also two reports of crashes that are purportedly linked to the problem, but the government agency lists no injuries. According to NHTSA, the issue may be getting worse because 60 percent of these allegations are from the past nine months.
A preliminary evaluation doesn't necessarily lead to a recall, though. NHTSA uses them "to assess the cause, scope and frequency of the alleged defect." Ford spokesperson Kelli Felker tells Autoblog: "We will cooperate with NHTSA on this investigation, as we always do."

The Office of Defects Investigation (ODI) has identified 32 complaints alleging electric vacuum assist pump failures resulting in loss of brake power assist and increased brake pedal effort in model year (MY) 2011-2012 Ford F-150 full-size pickup trucks equipped with 3.5L GTDI engine. None of the complaints reported any warning indicators to alert the driver of brake power assist loss or the potential of increased stopping distance. Two reports alleged crashes due to increased brake pedal effort required to stop or slow the vehicle. The complaints show an apparent increasing trend, with approximately 60 percent of complaints received within the past nine months.
A Preliminary Evaluation has been opened to assess the cause, scope and frequency of the alleged defect. The VOQs noted in the Failure Report are: 10723792, 10723033, 10721465, 10716441, 10713019, 10712465, 10706271, 10706217, 10700874, 10695537, 10678844, 10668069, 10666988, 10664415, 10662151, 10654472, 10650578, 10643075, 10640064, 10629319, 10621605, 10619545, 10617828, 10615536, 10610491, 10607811, 10605701, 10604687, 10575987, 10565994, 10554458, 10542098
