NHTSA Complaint #11431177 — 2012 FORD F-150

Vehicle sat idle in garage for two months. Started vehicle and brake pedal went to floor and was very soft. A warning was displayed on the instrument panel showing low brake fluid. Noting that master cylinder reservoir was almost empty I purchased a pint of DOT 3 brake fluid which I added to reservoir to "MAx" fill line. Started vehicle, brakes pumped up to a normal pedal pressure, took for a short test drive slowly testing brakes. All seemed normal at that time. Approximately 3 hours later I started vehicle, again noting that the brake pedal went to the floor. Checked the reservoir and found it almost empty again. Looked under vehicle and found no indication of fluid in any of the four corners by the wheels nor under the master cylinder. It is my belief that the fluid is leaking into the brake booster a problem which was addressed in a Safety Recall 20S31 issued by Ford Motor Company for a series of vehicles which although does not include my vehicle I believe that this issue is directly related and could also cause serious injury and/or damage if not repaired. I will have this issue fixed at my expense, however, I would be interested to learn if any other 2012 vehicles have experienced this problem.
