The National Highway Traffic Safety Administration is opening a preliminary evaluation into the 2011-2012 Ford F-150 with the 3.5-liter EcoBoost V6 because of potential failure of the power braking assist. If a recall is required, it could affect an estimated 250,000 of the trucks.
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.”
