The automatic emergency braking system prematurely and overly-aggressively takes over when I have full control of the situation. When it takes control it locks up all four wheels, each time almost causing a rear-end collision. It has done this on a total of 4 occasions under normal congested traffic situations. On or about 6/14/26 I was driving westbound on the Massachusetts Turnpike. There was a sudden traffic stop. I had sufficient distance to stop before colliding with the car in front of me and further had the passing side breakdown lane to divert into if necessary. The emergency braking software took over and locked up the wheels causing the person behind me to have a rear-end collision with my car. There was little-to-no damage and no injuries. The dangerous turnpike traffic conditions discouraged making a police report. Conclusion: System is overly aggressive and creates undue risk of personal injury. The risk far outweighs any benefit the system offers. - Plans to report issue to Mazda during next maintenance appt -No warning lights -Problem is re-occurring but not with independent entity (yet)
