2022 Rivian R1S Air Bags & Restraints Problems

All sensors failed. Once vehicle was parked completely and seatbelt was removed, the car automatically took off. It began accelerating on its own, full throttle (Rivian logs were retrieved to show this), then began crashing into multiple cars while still gaining speed. Logs also show that the breaks were applied during this time, but the accelerator was still engaged at full throttle. The car then launched itself into a light post. The car was able to clear the 2-3ft concrete base of the post and the metal beam crashed into the glass roof of the car (which was shattered and thankfully the surfboard racks prevented it from fully crashing into the vehicle - but the racks are completely crushed), the metal post then launched itself into two more vehicles as well as the car itself. Airbag was not deployed at any point, car was going over 30 mph when it finally stopped (the concrete base likely pierced the battery to make the car stop). Logs didn't even note that there was a crash and the vehicle is totaled. We have salvage holding off on destruction so that the EDR can be salvaged and retrieved.

When I am driving, my passenger sometimes does not trigger the airbag to activate. Depending on how they are sitting, many times the passenger airbag is set to "off" because it can not detect a passenger. The Rivian service center has investigated and mentioned there is no problem and that the passenger needs to sit more upright, but this still seems like a safety issue if we are driving and fail to notice that the passenger airbag is not activated

Passenger airbag sensor does not detect passenger reliably. My 13 year old son and my wife both have issues. They are both over 120 lbs, so I think they should trigger the sensor. I have had it serviced for this issue, but it did not fix the problem. It also will detect a person in the seat during a drive and turn off later in that same trip without stopping the car. It seems to me that the sensor needs to be more sensitive. And, once it detects a person in the seat, it should keep the airbag on until the car is stopped and door opened. My wife does not feel safe in the car as it stands now.
