NHTSA Complaint #11423536 — 2016 FORD F-150

Low brake fluid light came on while driving. Shortly thereafter (minutes) the brakes got very bad and unsafe. Basically the resistance left and the pedal went to the floor. It slowly stopped via brakes but very poorly. You couldn't make a quick stop if needed. Checked fluid it was empty. Added fluid. Drove to dealership, brakes were slightly better but sure enough 5 minutes into drive the low fluid light came on. I suspect it is emtpy again (I dropped at dealership and told them to check). Brakes starting working worse again, just like before (keep in mind they were'nt normal again even with the fluid, just a bit more resistance when i pumped the pedal). After the light came on, all resistances was gone again. Doing some research and talking to the dealership this sounds exactly like NHTSA campaing # 20V-332, however, my vehicle isn't covered because the cutoff for that is currently Aug 1 2016, while my truck was apparently built the following month in September. Dealer thinks it is the same issue. I called Ford and they are taking a wait and see attitude, but it sure seems fishy that the exact recall problem appears to suddenly pop up in a vehicle that fits all the descriptions except a month later...The guy I talked to said they used dealership reports to determine affected dates, so who knows. Car is at dealership getting fixed and it needs a new master cylinder.
