2019 BMW X4 Forward Collision Avoidance Warnings Problems

WHILE DRIVING, COLLISION DETECTION ACTIVATES FOR NO REASON. VERY RANDOM, SOMETIMES JUST WARNING LIGHTS AND SOUNDS, AND SOMETIMES SLAMMING ON BRAKES AT SPEED OVER 40 MPH. NO CARS COMING IN OTHER DIRECTION OR ANY OBSTACLES WHATSOEVER. WEATHER CLEAR. I ALMOST GOT REAR-ENDED ONCE. DID NOT ACTIVATE WHEN FOX RAN IN FRONT OF CAR. I CAN GO WEEKS WITHOUT THIS HAPPENING AND THEN IT COMES OUT OF THE BLUE. IT'S IN THE SHOP FOR THE THIRD TIME FOR THIS COMPLAINT AND SERVICE SAYS THEY HAVE NO "ERROR CODES" AND CAN'T RECREATE THE PROBLEM. BMWUSA TOLD SERVICE TO TRY TO RECREATE THE PROBLEM BY DRIVING IT OVERNIGHT. THERE'S A 50/50 CHANCE IT WILL HAPPEN WHEN THEY DRIVE IT, AND THERE STILL WON'T BE ERROR CODES! BMW WON'T AUTHORIZE ANY REPAIR UNTIL THEY GO THROUGH THESE STEPS. THIS HAS BEEN ON AND OFF FOR AT LEAST 6 MONTHS. DATE BELOW WAS MOST RECENT...
