Two major safety issues need to be reported: 1) The left front lower control arm falling off in the middle of driving, caused car wheel stuck on a traffic street (luckily it was off the freeway 5 minutes ago). The long bolts connected the lower control arms were loss due to the defective design (the bolts are screwed upward vertically, falling off is definitely just a matter of time). I found there was a class action against Tesla due to this problem (it is referred to Model X and S) 2) The other major safety issue I encountered as I turned on the advanced autopilot feature, the car could break suddenly without warning on the freeway. There were no cars or obstacles in the front. I researched online and found many Tesla owners have experienced this so called phantom breaking problem as I had (I had experienced this unsafe auto breaking randomly since I have driven this car)
