2020 Volkswagen Tiguan forward collision avoidance problems

I was driving and a vehicle was making a left hand turn, in the middle lane and they were in their lane and I was in mine, but the vehicle decided to use the automatic breaking which then cause me to have whiplash and it took a few seconds for the car to move and I had other cars behind me. Also, because this happened so quickly with no warning I first had to think did I hit the car, because I would have had no knowledge because the automatic stoping made noise and jolted me.

My car alerts me at random times when I am driving down open winding roads that I am going to get in a collision when there are no cars or other vehicles on the road. It also goes off when I'm driving through construction and there's cones on the side of the road but I'm not even close to hitting. In michigan, we have a lot of construction so it shouldn't be going off and scaring me all the time.
