“While driving across Speer Blvd in Denver, CO (6 lanes) the emergency assist brake engaged and brought my car to a complete stop. There were no cars or objects ahead of me and fortunately the cars behind me were able to stop.”

NHTSA complaint #11468192, filed 2022-06

“The Automatic Emergency Braking system is activated even if there is nothing in front of the car. The car stops on its own. This has happened 11 times. Yes, my car is available for inspection. I do not know when it's going to happen. My car has malfunctioned like this 11 times. I can get hit from behind since the car is suddenly and unexpectedly braking. The dealership has not been able to reproduce the problem. The local dealership told me that Mazda is aware of the problem, but does not know what is causing it or how to fix it. …”
