NHTSA Complaint #11679562 — 2014 FORD F-150

While leaving the VA parking lot, and after breaking 3 times on the way out, as I approached a major intersection, the break pedal dropped to the floor and a low break fluid warning appeared on the display. My slow approach allowed me to stop. Checked the reservoir and it was empty. I walked to the gas station and purchased break fluid, when I returned, I checked under the vehicle for a leak, to no avail. I walked back to the spot I was parked but there was no indication of a leak. I was able to get my car home, and filled the break container intending on bleeding the lines; however, Florida weather forced to wait a day. Today, Saturday, I proceeded to bleed the lines but the reservoir was empty. Again, no signs of leakage around tires, break lines, reservoir, master cylinder. Everything I have searched regarding this indicates a large population of 2024-18 F150 with a master cylinder failure.
