Consumer Description

The automatic braking engaged without warning and without cause. There was nothing directly in front of the car that was a possible collision threat. I suffered a neck injury as a result of the force in which the car stopped. Fortunately the driver behind me was able to stop. The car was taken to the original Mazda dealer and I was told this is a problem with my car but that they had no permanent fix, nor the ability to permanently shut off this system available until "corporate got back to them." They did not provide any paperwork and stated "we will call you when we have something." I now have a car I am scared to drive.
