Rivian R1S Incident

On August [XXX], 2024, at approximately 8:01 AM ET the subject vehicle was traveling with adaptive cruise control (ACC) engaged at a speed of approximately 76 mph. ACC is not a level 2 ADAS system, but Rivian is submitting this report because there was some uncertainty in the verbal complaint about whether the driver was allegedly using ACC or Highway Assist (HWA), which is a level 2 feature. The driver initially reported that they were using ACC, but the Rivian call center mistakenly assumed HWA was activated and noted it as such. However, vehicle telematics data demonstrates that HWA was not active during the crash or in the 30 seconds prior to this crash and that ACC was the system in use leading up to the crash. The verbal report from the driver was difficult to understand but Rivians takeaway from the incident is that the vehicle was in the left lane with ACC activated when the lane ended. The driver admitted that they did not react to the lane ending in time and the vehicle impacted the center divider with the side of the vehicle. Damage to the vehicle is unknown but the customer reported that the airbags deployed and that the vehicle had to be towed.
