There have been 3 instances of the same incident of the Automatic Emergency Breaking system failing, the 3 times has happened over the 8 months I have owned the car. Mercedes has aknowledged the failure of the automatic breaking system but they do not have any fixes for it. When I am driving, if the safety system senses a police radar system a car may have installed (like an old school one on a civilian's car dashboard) the car's security system "shuts down" for a couple seconds and slams on the breaks nearly causing a crash. I have been driving at 15-20 MPH on a clear street and out of nowhere the car slams on the breaks because it detects someone's radar detector. As you can imagine, this is absolutley terrifying to be driving on a clear street and have the car slam on it's breaks. My heart rate goes up, I have been visibly shaken up. The feeling is as if I got into a car accident-but I didn't it was self-induced by the vehicle. I am worried if someone is driving behind me and is not prepared for the car to break, I will be rear-ended. Please help Mercedes owners fix this, it's horrible.
