“There was a trash can on the edge of the road and my vehicle was in autopilot/FSD mode and for some reason it swerved over too close to the edge of the road. I intervened in time to avoid hitting the trash can head-on but it still struck the passenger side mirror and scraped across the passenger rear fender. The mirror got slammed into the passenger side door causing damage to the door and trim at the bottom of the passenger side window.”

“On at least nine occasions the car has very suddenly and with no input from driver braked hard during passing another vehicle, when assuming the original lane after passing a vehicle, and, on one occasion when no other vehicle was close by. I have brought all incidents to Tesla's attention. They tell me the problem resides in the software of the car and that they are working on it . This is a very serious problem, which has been going on for over a year in my case. A totally unacceptable and extremely dangerous situation! …”

“I have never received an audible alert for my blind spot warning. There is no light on the outside mirrors or anywhere else inside the vehicle to catch your attention. If I am looking at my display in front of my steering wheel I will see a car that is in my blindspot change from GRAY to RED when I activate my blinker; however, the car has never beeped or alerted me beyond passively changing the car color to red on my display screen. If I'm changing lanes I am not looking at my screen which is directly in front of me, I'm looking at the road and I'm looking left or right. …”
