2018 Tesla Model 3 body & structure problems

I was driving on auto pilot mode when I was going to make a right hand turn when in order to slow down at the traffic ahead of me, I applied the brakes but there was no brake action whatsoever. This was not a panic situation, it was just normal braking. When the brakes failed to actuate and the vehicle accordingly wasn't slowing down, in order to avoid hitting pedestrians or the vehicle in front of me, I swerved to the right and ended up hitting a tree.

I was involved in a car crash with the autopilot activated. The autopilot has a flaw where it cannot detect when a large vehicle like an 18 wheeler or cement truck in merging into the lane. It sees a large gap and while the front part of the vehicle is slowly snaking into the lane it starts to accelerate. I hit the side of a cement truck and had 8k in damages. I reached out to tesla without any response.
