NHTSA Investigating Reports of Brake Assist Loss in Ford F-150 Trucks
The National Highway Traffic Safety Administration (NHTSA) is investigating reports of braking issues in model year 2011-2012 Ford F-150 full-size pickup trucks equipped with a 3.5L GTDI engine.
NHTSA's Office of Defects Investigation (ODI) has identified 32 vehicle owner complaints alleging electric vacuum assist pump failures resulting in loss of brake power assist and increased brake pedal effort in the subject F-150 trucks.
ODI says that 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 of the complaints report vehicle crashes that occurred as a result of the increased brake pedal effort required to stop or slow the vehicle.
According to ODI, approximately 60 percent of the complaints involving this issue have been received within the past nine months, showing an increasing trend.
ODI has opened a Preliminary Evaluation investigation to assess the cause, scope, frequency and potential safety-related consequences of the alleged defect. An estimated 250,000 Ford F-150 trucks could be impacted.
ODI is also currently investigating reports of similar braking problems in model year 2013 Dodge Dart vehicles.
