The National Highway Traffic Safety Administration said Friday it is opening an investigation into 250,000 2011 and 2012 Ford F-150 pickups for braking problems linked to two crashes.
The investigation includes the F-150 with a 3.5 liter gasoline turbo direct-injection engine and comes after 32 complaints allege electric vacuum assist pump failures resulting in loss of brake power assist and increased brake pedal effort.
NHTSA said “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.”
