Rivian R1S Incident

On March [XXX], 2025, at approximately 6:45 pm ET, the subject vehicle was traveling with Highway Assist (HWA) engaged at a speed of approximately 73 mph. At 6:45:30 PM there was a significant steering input from the driver that overrides HWA, which transitions the vehicle into Adaptive Cruise Control (ACC). The vehicle continued in ACC for approximately 1 second, while drifting out of the lane to the left, until accelerometer data shows the vehicle comes into contact with an object at 6:45:31 PM ET. The vehicle then comes to a full rest about 6 seconds later. Just over one hour later, at 8:04 pm ET, the customer called Rivian asking for information about long distance towing. Information was provided but a tow was not requested by the customer or arranged by Rivian and it is unknown if the vehicle was actually towed. The customer did not provide any additional information about the nature of the crash or make any allegations that the performance of the vehicle was a factor. Rivian believes that the driver failing to take control of the vehicle after they cancelled HWA was the cause of the crash and vehicle performance was not a factor.
