2022 Honda Civic forward collision avoidance problems

The Collision Mitigation System has spontaneously engaged 4 times with no obstacles in front or to the side of my car. 3 incidents were on city streets with a low rate of speed. The 4th incident happened on the freeway at about 65MPH! I had no vehicles in front of me or to the side of me but I had several behind me. The car came to a screeching halt on the freeway with a truck behind me. Thankfully the truck was far enough behind that he was able to maneuver around me.
