NHTSA Complaint #11484688 — 2022 BMW IX

On September 1st 2022, under heavy rain, the rear bumper fell partially, and the part that was still attached to the car dragged it along with the cables, camera, sensors, etc. The car only notified a sensor cleaning malfunction. I kept driving when saw the sensor warning. There was no noise or indication of anything going on in the car. It was when another driver made gestures for me to stop, and told me that my bumper was dragging, when I learned the situation. The safety of others was at risk because only a small plastic pin was holding it, a tail light went God knows where and it could had hit other drivers in the highway. I don't know if the problem has been or not reproduced by BMW. I do know that Tesla cars, that have the same type of engine, had identified this problems in their cars. BMW USA was notified and they deny it. They allege that it was a "collision" what provoked this. There wasn't any collision, it was just water from the rain. This car has video capability for theft and collision and in its memory there is nothing about a collision or the event of the bumper falling. The theft/collision system is in fact working because when the towing service came to pick it up, it registered theft pictures. I went to the police first to make the report. This is the report number: Q2022-5-050-8951, the agent was Pablo A Morales #29480 at Mayaguez Police Station in Puerto Rico. Their phone number is (787) 832-9696. From there, the vehicle was sent directly to the BMW service center. They inspected it, in fact, they still have it. The car insurance representative just inspected it as well, yesterday morning. The only message that turned on was the sensor cleaning one, since it was raining, I assumed it was due to that. The message kept appearing. There were no other symptoms or messages.
