Rearview System Braking problems of the 2021 BMW X5

You get no warning when backing out of a parking spot all features are on but no warning.

Rear cross traffic alert does not work in the subject car. BMW owners' manual describes a system that should alert from two parking spaces away while backing out, the system gives no alert as described. What follows is my post to a BMW owner's group where members are discussing similar issues with their vehicles. This problem is a large one and needs to be investigated. Rear cross traffic alert is a critical safety system. "regional field service rep spent several hours last week with the car. Made some updates/integrations and declared the systems now working. I did some controlled testing in a parking lot in reverse with both brake applied and rolling in reverse. Zero visual or acoustic alert from the rear cross traffic alert system. I am convinced BMW and the dealers are trying to cover up this colossal failure of a very important and basic safety feature BMW says they sold us! I will give corporate one more try and then will report to NHTSA that BMW has a major defect in their cars. " I am scheduled to talk with the regional BMW engineer in the next two weeks. Is there a means for me to update this submission?.

When in reverse, the vehicle doesn't give any warning (audio or visual) that a person or vehicle is approaching on either side.

When reversing out of driveway/parking space, the rear cross traffic warning alert doesn't give any warning until my vehicle is inches from another vehicle. The system isn't sensitive enough.

System fails to notify me of pedestrians/cross traffic when backing out of driveway, parking lots, etc. Multiple near misses. Orange/red shadows on screen do not appear. Ditto for beeps.
