First time-Driving on road at 45 mph when my car started flashing red for a forward collision and my cars automatic emergency brake stopped me immediately with nothing in front of me on a clear road. The stop was so forceful we thought we were hit from behind with no one around us. The force causing both my teenage son and I to have strained necks with the force of us stopping immediately. I was forced so far forward my head hit the windshield. Second time-driving in a parking lot at 10 mph when my cars emergency red flashed in dashboard then immediately stopping my car with no car or speed bumps ahead of me. The car behind me nearly hitting me. We got out of car to ensure they had not hit us because again with the force of the immediate stop, all in the car were forced forward in a jerking position. Took into manufacture and they said nothing was showing up and they have no idea what Iâm talking about
