Vehicle was involved in a rear end collision. Vehicle was setup to have Emergency Braking enabled and used the Rivian High Regen setting (one pedal driving). In freeway traffic, the vehicle in front slowed quickly. The vehicle initiated emergency braking, but when the vehicle in front sped away, the vehicle failed to release emergency braking thus resulting in the car behind hitting my Rivian. There was no vehicle to the right of my car. I should have been able to accelerate out of the way and move to the right. It would appear the Rivian system requires a FULL STOP. I was unable to accelerate to mitigate the rear collision damage. Secondly, the vehicle acted like it did not recognize HIGH REGEN setting as a brake input. I have had multiple time where it flashed at me to brake and the HIGH REGEN setting was stopping the vehicle. This is not acceptable. Rivian was contacted and the vehicle taken for service and repair. I was informed that they reviewed the accident and that all systems checked okay. Rivian noted that I did request acceleration from the car, but I did not hold the accelerator long enough for the vehicle to allow me to regain control. I have asked what the threshold is to regain control and they were unable to answer. Minimally I would hope they can describe how their system has been designed so that I can properly drive their vehicle. Ideally, the system should display emergency information on how to override in the event it forces the car to stop on a freeway. I am sure the Rivian system is smart enough to see that I was on a freeway and I would hope smart enough to detect that I could have safely moved to the right as other cars did to avoid collision. I firmly believe the incident could have been avoided. Vehicle had all cameras enabled and full accident is recorded and available for review. Rivian also collected vehicle diagnostic logs.

Below are the diagnostics that Rivian says happened. I pulled into a parking space and as I placed my foot on the brake the car launched forward. I DID NOT hold both peddles down at the same time. The car malfunctioned and thank god I hit another parked car and not a person. The car has no been in the shop and at Rivian service center for the last 4 months. They are taking no responsibility for the events and are not returning my calls. I have read on many chat boards that this has happened to other drivers and they say it is "user error". a car with this much power should not be accidentally able to be put into launch mode. Vehicle enters a parking lot area at approximately 6:38 PM PST as vehicle speed is reduced and steering is consistent with parking lot maneuvers. Vehicle proceeds to travel at speeds below 15 mph. At approximately 6:40 PM PST the vehicle beings to turn left, then right while traveling at speeds below 7 mph. At this time, the steering wheel is returned to a centered position when the accelerator pedal is depressed to 98% application. Accelerator pedal and brake pedal are depressed simultaneously again as the vehicle comes into contact with another vehicle. Vehicle comes to a complete stop at 6:40:48 PM PST and remains in Drive. Vehicle remains in Drive and does not move for almost 8 minutes until vehicle is shifted into Reverse then Park at approximately 6:48:18 PM PST.
