NHTSA Complaint #11467519 — 2018 TESLA MODEL 3

When driving on local roads and the interstate the card suddenly brakes for no reason when using auto pilot or full self driving. Sometimes it seems to be triggered by shadows from trees or other objects on the road and other times for no reason at all. I have been going 45 mph and the car suddenly braked to 30mph. I have been on the open interstate doing 70 mph when the car will suddenly and violently brake when there is a car on your bumper and this is very dangerous. If you dont keep your foot over the gas while driving and force the car to speed up it will cause an accident bc it will brake until the car is stopped probably. Somone needs to look into tesla and the phantom braking on auto pilot and full self driving. i have owned this car for almost 4 years and over the last 1 year this has gotten progressivley worse when they switched from using the radar sensor in the front to camera only vision called tesla vision. it is unsafe and im sure it's causing accidents today and needs to be investigated since Tesla cant seem to fix it.
