Automatic Emergency Braking Problems of BMW 540

Problem: I recently had several incidents when the rab (rear automatic brake) on the 2024 BMW 540i vehicle did not work on multiple occasions. The vehicle never stopped as I backed out of my parking space. Afterwards I tested the rab by perpendicularly slowly walking behind the car. I had to run out of the way when the vehicle was continuing to move when approximately 12” from me. I tested both vehicles, 540i & x-3, with the same results.   as a further test I placed a plastic figure that’s ordinarily used a warning to drivers of children playing in the area. Results while slowly backing was that the vehicle hit (bumped) the little green “man”. I later discussed this issue with my wife that drives the 2024 x-3. She then informed me that she too almost backed into a pedestrian.   I then did the same tests on my wife’s 2024 x-3, VIN [xxx] , with the exact same results. BMW of wesley chapel had no solution. I spoke with managers doonan and hernandez. I believe the photos demonstrate the slight graze of an item whereby the rab should have stopped the car; it never should have allowed the collision.
