NHTSA is investigating the 2011-2012 F-150 with the 3.5-liter EcoBoost V6 for potential loss of power braking assist. There are two allegations of crashes from this issue, and a recall could affect an estimated 250,000 of the pickups.

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.
