NHTSA’s Office of Defects Investigation opens investigation of 2011-2012 Ford F-150 full-size pickup trucks equipped with 3.5L GTDI engine over loss of brake power assist




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.


Ford named in class action over alleged safety defect in 2011-2012 Ford F150s

The class action against the Ford Motor Company alleges that the company’s Ford F150 trucks contain a dangerous safety defect that causes the vehicles to shake violently, shudder and stall when attempting to accelerate.

As alleged, the vehicles suffered from a defect, which is caused by a flaw in Ford’s Charge Air Cooler (CAC) system. The complaint alleges that the system, which is designed to cool air before it reaches the engine, causes condensation to build up inside the air intake tube, especially in more humid climates.

According to the complaint when drivers accelerate moisture moves into the engine, causing the vehicle to shudder. In severe cases, the F150’s computer system senses the danger and forces the vehicle into “limp mode” to prevent damage.

The suit claims that Ford is completely aware of the issue, and has gone as far as to warn dealers in a secret memo, noting that vehicles may, “stumble and/or misfire on hard acceleration after an extended drive at highway speeds during high humid or damp conditions.”

The lawsuit against Ford seeks to provide compensation to all current or former owners and/or lessees of Model Year 2011-2012 Ford F-150 vehicles.
