1> What component or system failed or malfunctioned, and is it available for inspection upon request? * The sensors don't detect the object sometimes. There were 2 incidents when the car sensors did not detect the object a> In my office parking lot the rear sensors did not detect the fire hydrant and did not make the beep noise resulting in a collision. b> I was driving in my neighborhood; I was blinded by the sun and couldn't see the road ahead. Again, the sensors did not detect the car in front i ended up in a collision. 2> How was your safety or the safety of others put at risk? * I had a collision with another car parked by the curbside. Luckily no one was in the other car but both cars had severe damages. I had bruises on my left-hand forearm. 3> Has the problem been reproduced or confirmed by a dealer or independent service center? * When the first incident happened, I was not able to provide Rivian accurate date and time of the incident and the gear guard did not record the collision although it was supposed to record. So I went back to my office parking lot and i reproduced the problem 1 time after trying several attempts and shared the video with Rivian. I have had too many email exchanges with Rivian to help address the issue but they did not help. 4> Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? * When i reported the first-time issue first time, Rivian inspected the sensors on May 29th 2024 and
