On [XXX] while driving my 2019 Honda Insight Touring at approximately 35 mph on [XXX] , the vehicle’s automatic emergency braking system suddenly activated without any obstacle present. The car braked very hard, creating a dangerous situation in traffic. This was not the first time it has happened. The same issue occurred on two separate occasions in 2022, also with no vehicles or obstacles nearby. Each time, the system engaged abruptly and without warning. I am concerned about the safety risk of the Collision Mitigation Braking System (CMBS) activating erroneously, as it could easily cause a rear-end collision.

Both types of errors have occurred multiple times. Sometimes, the forward collision warning system triggers when no obstruction is present. More frequently, the adaptive cruise control decelerates even when no car is nearby or the car in front of me has not decelerated.
