Brake Sensor Problems of BMW X3

My car has been at the BMW dealership twice for these incidents. The incidents have happened a total of 4 times. The first time, I was driving about 45 miles per hour along the city street, woodruff Ave in long beach. It was a sunny day and there were no other cars around me when the car suddenly starts beeping and dash blinks and then car slams on brakes automatically until it comes to a stop. I am not sure what caused the problem but I think it may be the sensors for the automatic collision braking system. The second time I was going about 15 mph coming up to a right turn in the right turn lane of a city street. There was a car in the left lane that was stopped at the traffic light. My car then sounds the alarm, flashes the warning and slams on the brakes to a stop. My business partner was in the car with me during this time. The third time was October 16, 2020 when I was driving on a city street and there was a car stopped about 30 feet ahead. I was slowing down when the car sounded the alarm, flashed on the screen the warning (which I took a pic of) and the brakes applied automatically and the car stopped. The fourth and last time, the car did not apply the brakes but the warning systems came on and the dash flashed. I took the car again to BMW and BMW north America sent out a field engineer. They have the car from October 23, 2020 to November 18, 2020 at which time they said they could not find anything wrong with my car.
