Our 2024 Rivian came to a stop at a light with three cars in front of it. We have the video from a home on the street. ABout 12-15 feet behind the next car. Rivian comes to a complete stop. Sits about 5 seconds. Then car surges forward to rear end the car in front. that car hits another car and another car. THe rivian only makes direct contact to the car in front then hits aa parked car next to that one, through a 2' block wall and hits a building. No one hurt on site. TO add to the exact problem...Just prior to the vehicle coming to a stop a passenger in the front seat and a passenger in the back seat were listening to an audio book. its started skipping forward and slowing down. Car comes to a stop. screens go blank/black in the car. ALl three people can attest to this. The driver had her foot on the break as this happened and the car surges forward and proceeds to do the damage it does. IT is this unintended surge that was the issue. Seems a few people have had this issue.

Vehicle stopped working while driving. It completely shut off even though I had 250 miles of range available. It looked up the rear wheels and came to a very harsh stop. It was immobilized and even with a hard reset it didn’t come back to life.

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.

At 56,083 miles, my 2024 Rivian R1S experienced a suspension warning while driving on the US-101 Freeway and entered reduced-performance/turtle mode, limiting the vehicle to approximately 50 MPH while surrounding traffic was traveling substantially faster. The sudden speed differential created a serious highway collision risk. Rivian inspected the vehicle and diagnosed fault P12DF7A, “Roll Control Cross Circuit Static Leakage Check Failure.” The technician repeated the hydraulic leakage test to rule out a false positive. After draining the hydraulic fluid, Rivian found metal debris throughout the system and documented that it was causing system contamination. Rivian separately confirmed in writing that the source was an “internal mechanical failure in the system.” Rivian Repair Invoice INV_20260811-204135.pdf Rivian determined that the contaminated system required replacement of the hydraulic suspension manifold, hydraulic pump and all four dampers. Its repair procedure requires all four dampers to be replaced when metal debris contaminates the system. Rivian - Metal Debris Email.pdf Critically, Rivian advised me that even if turtle mode did not immediately recur, recurrence was “inevitable in the future” because of the metal debris and stated: “For your safety, we strongly advise against driving the vehicle in this condition prior to completing the full repair.” Rivian - Metal Debris Email.pdf I previously reported excessive suspension clicking to Rivian at approximately 44,000 miles while under warranty. I am aware of at least two potentially similar R1 failures, including another involving reported metal fragments and turtle mode. I request NHTSA investigate whether an internal mechanical failure can introduce metal debris into the interconnected R1 hydraulic suspension system, contaminate multiple components and cause reduced-performance mode at highway speed, and whether similar R1S/R1T incidents indicate a broader safety defect.

My vehicle has been a service seven times, each time I have complained about my wife not being recognized by the passenger seat. She weighs 100 pounds, and I’m told that the weight limit is 65. On the latest visit they replaced the passenger seat and told me if it still does it, then it is a design flaw, and I’ll have to deal with it. Don’t find this acceptable as it affects my wife’s safety, and would like the manufacturer to rectify the issues of the airbag will function correctly.

While backing very slowly into a parking space, I lightly contacted small twigs (please see photo) with the vehicle. There was no impact with another vehicle, pole, wall, or solid object, and no significant force was applied. A child seated in the third row mentioned hearing a light scraping sound. Immediately afterward, the rear window suddenly and violently exploded, sending glass shards into the interior of the vehicle. The glass dispersed forward into the cabin, creating a significant safety hazard for the occupants, including children. There was no prior damage to the window, no visible cracks before the incident, and no collision that would reasonably explain the shattering of tempered glass. The explosion appeared spontaneous and disproportionate to the minor contact with twigs. This incident raises serious concerns about rear window glass integrity and the risk of injury to passengers, particularly children seated near the rear of the vehicle.

Front wheel hub bolts back out on their own. This is a huge safety problem and needs a public recall. It is a known problem. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
