On [XXX] I went to start the car and received warnings about Manual Braking being engaged and to contact roadside service along with other notifications and the car wouldn't power on. After numerous attempts the car powered up and alerted me Drive Carefully Fault. I began to drive slowly through a parking lot and it took over 200 lbs of pressure to bring the car to a complete slow stop. I pulled over and turned off the car. I tried rebooting the car and did so assuming it was a bug in the system. When the car powered back up the flaw had vanished and I carefully drove home. A short time later when I turned the car on I followed the instructions and called roadside service and described my situation. To my surprise, roadside service had never heard of the problem before. I then contacted Rusnak BMW service center and talked them through what was happening. Once again I was surprised to learn that they too had never heard of the problem. I brought the car into Rusnak BMW on May 30th. Over the course of the next week and a half I was never given any concrete news about why the car had acted that way. In fact I was told that they had to elevate the situation to NEW JERSEY where the higher ups would review the situation. No concrete information was provided other than they drove the car for 11 miles and felt comfortable having me pickup the car. Admittedly, it was frustrating to be called to pickup my car not knowing why there was a problem with the braking system and being given no assurances it wouldn't happen again. As I went to leave the Rusnak dealership my car wouldn't start and the process began all over as it had on [XXX]. When I got the car to start the brakes were not reacting and I drove the car 100 feet to the front door of BMW front door and with over 200lbs brought the car to a stop. Rusnak BMW is once again working on a problem they seemingly dont know how to fix. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
