Brake Hoses, Lines/piping, And Fittings problems of the 2012 Ford Edge

I had my brake booster replaced about a year ago. About 4 months ago my brake pedal was going to the floor. Took it to the Ford dealer but the brakes were ok again. They said they could diagnose the problem. 2 weeks ago same problem pedal going the floor, now spongy pedal. Had a new brake hose put on and the brakes bled and it is still spongy. Trouble stopping very dangerous!!.

Bought this car oct 2019. Tonight, Aug 2020, after driving in an intense thunderstorm on the highway doing 70mph, brake pedal suddenly travelled all the way to the floor. Only the last 1/4" (estimated) of travel actually applied any braking effort at all. I thought maybe someone had cut a brake line or something. . . But once I pulled over and turned the car off I checked fluids, etc. (all normal). After restarting the engine, brakes were working properly. Very scary and very dangerous!!! when can I expect this to happen again?!? I really wish I didnt have to drive this thing every night. . .

Driving the vehicle on the freeway when the brakes took a substantial amount of force to stop. The car was sent to a Ford licensed dealership where they diagnosed the brake booster has failed as well as air in the brake lines.

Backing down driveway in reverse the brakes failed to function properly. I had to stand on them (push with all my leg strength) and then all of a sudden they were working with the power assist. Thankfully no one was coming down the street at the time. I'm certain this is a design or manufacturing flaw. It was similar to the time I broke a brake line and only had the rear drum brakes working and had to use the emergency brake to stop. To me the brakes are mission critical for safety and if Ford won't admit it and have a recall then the ntsb must step in. This thread is loaded with similar complaints and something needs to be rectified before some one is killed.
