## Narrative
This afternoon, while I was driving on freeway at a normal speed (75 miles/hour) with an ample distance (30 feet) from the car in front of me , I suddenly felt a huge impact.  It was so violent that  I immediately thought my car was hit by the car behind me.  I stopped the car on freeway and called 911.  But from the back mirror, I did not see any damage on the car  behind me.   I got out to inspect my car but did not see any collision damage.  According to my online search, this model - Mercedes-Benz EQS - has a frequently reported issue of "Phantom Braking" from the Forward Collision Avoidance System.   It was very startling and dangerous experience for me.  Now 5 hours later I still feel the pain in my neck and back from the impact.  Please address this issue to save lives.
