2024 RIVIAN R1S

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.

clunking/thumping noise coming from front end over speed bumps like something is loose or going to fall apart. have taken car into service few times and was told its normal, its getting worse. Online forum threads have mentioned same issue , I am afraid one of these days something going to snap and cause a breakdown or even worse terrible accident.

Rivian has a 'kneel' option that uses the powered air suspension to lower the vehicle to make entry and exiting the vehicle easier for users. Yes, this can be turned off or on. When on, the function stops if a main door (driver/passenger) is open and left open the car will not continue to kneel for safety purposes. However, it does NOT stop if you are using the rear hatch to access anything. The car continues to kneel. I have hit my head multiple times on the rear hatch because I am behind the vehicle and assume a certain amount of head room and the car is still kneeling and I do not realize it and stand up like I was and hit my head. I have notified Rivian and asked for updates. I consider this a critical issue and has caused minor injury or confusion momentarily. I live on a busy street and the last thing I need is to hit my head and be knocked out. I have not heard anything from Rivian on my request and an update came out to 'fix' items but this was not included. I advised if it was not I would file an official complaint to make them take security and safety issues seriously.

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.
