I was driving down the highway, with no one in front of me, and my car alerted BRAKE and brought my car from 70 to an almost complete stop. This jerked myself and my passenger and caused a heat mark from the seat belt on my collar bone. It has done it multiple times since then. I’m terrified to be in traffic and for it to do this. This is most definitely putting my safety at risk, and the safety of others. I have not taken it to the dealership yet.
