NHTSA Complaint #11495626 — 2019 TESLA MODEL 3

Two lane highway I was in the left lane with the cruise control on not Full Self Driving. In the right lane was a semi which I came up along side off on the left , I was driving 70mph. (Speed limit) The car suddenly hard braked on it’s own. The car behind me had to brake to avoid an accident and went into the dirt. After that on this same drive, there were at least 6 more instances of phantom braking when traveling over a “wash bridge “ going under a highway sign, driving along side another semi and once without anyone near and an open road. This also happened 3 months ago and when I reported it to Tesla they said when I received the FULL self driving down load which I got the next day, the problem should be corrected. I also reported the previous problem to you, the case # 11488958.
