2023 Audi SQ5

Purchased car 3/18/23. Not even two months after purchasing - on 5/11/23, I was in far left lane going to make a left turn - stopped and had blinker on. No cars, pedestrians or any items were in front or behind me. Out of nowhere the car slams on breaks and the red presense light comes up on dashboard. Vehicle may have even turned off. Both myself and passenger thought we had been hit from behind due to the amount of force and both had neck pain afterwards. Only 3 days later, nearly the exact same thing occurred. I was in far left turn lane but this time a car was behind me also wanting to turn. When proceeding to turn, the brakes were slammed on. I don't recall seeing the presense light this time. My dog flew out of backseat and the car behind me honked and driver was screaming out his window at me. I was lucky I was not rear ended. I called the dealership who explained this happens with the presense and they could change settings but it is a known complaint. Said it can be caused by a dirty sensor or even sunlight. I took the car to Audi who had engineers look at it and verified that the events did occur on these dates and said it was "environmental concerns" which could be several things since there wasn't a vehicle around - suggested maybe sunlight reflecting off a street sign. Presense is not able to be turned off permanently - must go through a series of steps to deactivate. The car is not safe to drive with presense on - period. Also mentioned there was a technical service bulletin 2058077. There have been numerous people online describing accidents from this. The public should be aware of this as I am sure deaths have already occurred from this. There are numerous complaints on the audi boards and I've read of at least one lawsuit where driver was seriously injured from it breaking so hard that his lung was crushed.
