NHTSA complaint: 2022 RIVIAN R1S — VEHICLE SPEED CONTROL
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.
