NHTSA Complaint #11549848 — 2017 FORD F-150

My truck went to Bolton Ford in Lake Charles, Louisiana for a Brake Master Cylinder Recall on September 07, 2023. Upon receiving my truck back that afternoon, the repair was stated to have been successfully completed. After driving about twenty miles, a loud alert came on in the truck, and an alert came on the dash stating, "Check Brake System", also the Brake light by the tachometer. I immediately pulled over and called the dealership service department. I checked under the hood, and only found that the fluid reservoir cap was slightly loose. They advised watching the truck and getting it back as soon as I could. Turning the key off, cleared the warning. The warning happened two more times that day on my way home. I returned the truck back to the dealer for service two more times again after this time for the same problem. They have worked on my vehicle a total of three times for the same problem and still not fixed. It went in for a preventative recall, and now is constantly malfunctioning. I picked it up yesterday (10/12/2023) after the third repair attempt. I drove on the interstate 35 miles. Returning, the same "Check Brake" warning alerted, and the brakes were almost impossible to apply when I pressed them. Finally, the brakes applied. This has become a very dangerous situation. Please advise where to go from here.
