The specific failed component is UNKNOWN. My 2023 Rivian R1S has experienced recurring intermittent Limited Performance/loss-of-propulsion-type events since within months of delivery. The events involve unexpected reduction of available propulsion, reduced maximum speed, warnings, restarts, system/display restarts, and at times inability to move or change gears. Rivian documented Limited Performance while driving in January 2024. In March 2024, Rivian documented loss of propulsion and an approximately 10 mph maximum speed; a reset and sleep cycle did not correct the condition. Rivian later stated it could not reproduce the concern. In March 2026, Rivian documented Limited Performance while driving, the vehicle coming to a stop, and multiple restarts before it would move. On September 4, 2026, the vehicle again entered Limited Performance and would not exceed approximately 20 mph. After a restart, it operated normally. Rivian received the vehicle for service on September 7. On September 9, Rivian stated that initial testing did not duplicate the Limited Performance telltale, that it had no confirmed repair, and that it proposed an extended approximately 100-mile test drive to try to reproduce the issue. I retained photos and videos of additional events involving reduced speed, warnings, restarts, and inability to move. The intermittent loss or reduction of propulsion while driving can affect my ability to maintain safe speed and creates a potential crash risk. There was no crash, injury, or fire in the incidents described.

On XXX, at approximately 12:19 PM, I was in the drive-through lane at a Chick-fil-A in [XXX], with my child as a passenger. I was using one-pedal driving mode and had come to a complete stop with my foot off the accelerator. I turned briefly to hand my child an ice cream cup, and when I looked back at the road, the vehicle was accelerating at full power with no contact from either pedal. To avoid striking the vehicles stopped ahead of me in the drive-through line, I swerved left into the Chick-fil-A building, causing a collision with the building. This put myself, my child, and nearby pedestrians and drivers at serious risk of injury. Cedar Park Police Department responded to the scene and a report was filed. I have video footage of the incident. The vehicle is available for inspection upon request. I believe the accelerator pedal and/or its sensor malfunctioned, possibly related to a known issue some other Rivian owners have reported involving cabin temperature affecting the pedal sensor; this has not yet been confirmed by a dealer or manufacturer. I am requesting that the manufacturer pull the vehicle’s black box/EDR data and perform full diagnostics on the pedal and sensor.

I pulled into my semicircle, long driveway as I do every morning, and stopped at the top by releasing my foot off the accelerator (no need for brakes as it is an EV). I opened the garage door and slowly stepped on the accelerator, but it started to go fast, and I felt out of control. I immediately released my foot off the accelerator (which should have stopped the vehicle) and slammed on the brakes (there is proof in my driveway with tire marks leading up to the accident) but still did not stop. I quickly realized I was going to crash into the garage, and possibly into the house, so I steered away as much as I could to only drive into and through the side of the garage wall. The space I had would have given me enough time to stop had the car not been driving at a fast speed. Even the neighbors heard braking and ran outside to see what was happening. There is a recording on a ring cam, and you can hear him say "I heard brakes". Oddly, the massive impact did not deploy the airbags. Also, the car usually records all incidents with time before and after (it has successfully done this before when I was rear ended and will if you get too close to anything), but for some reason it recorded what was labeled "incident" and you can only see me pulling into the driveway, the garage door going up, and then the video stops - no record of the crash. The car should have also detected the house. The car only stopped after driving through concrete and stucco, and up the stairs. House has massive damage, personal items in the garage destroyed, and the vehicle is possibly unsalvageable. It took until the next day to see if we could remove the vehicle from my house, but it is now at the service center and Rivian has been notified. I've since researched online and found countless similar incidents.

I own a 2023 Rivian R1S, early production vehicle #531, with approximately 93,000 miles. While driving, I noticed the vehicle's suspension was not functioning normally. After parking, the front passenger side of the vehicle dropped significantly lower than the other side, leaving the vehicle visibly uneven. I also received suspension warnings indicating that the suspension system was too hot and needed to cool. I brought the vehicle to a Rivian Service Center. Rivian diagnosed a failed/leaking damper and a failed air compressor. I was informed that only one damper had failed, but that all four dampers must be replaced because Rivian changed the manufacturer of the dampers and the replacement components are not compatible with the original dampers installed on my vehicle. The estimated repair cost is approximately $8,000. I am concerned that this may represent a safety-related failure of the early-generation R1S suspension system rather than normal wear. The suspension failure resulted in a substantial and visible change in the vehicle's ride height and occurred after I had experienced suspension behavior changing while driving. I have also found reports from other Gen 1 Rivian owners describing leaking hydraulic dampers, damper failures, suspension sag or collapse, multiple damper replacements, and air-compressor failures. Some owners report Rivian replacing their original dampers with subsequently revised components. I am particularly concerned that Rivian has informed me that the original dampers on my vehicle can no longer be replaced individually because the damper manufacturer/component has changed. Although only one damper on my vehicle failed, Rivian states that all four must now be replaced. I am submitting this complaint because a suspension failure that causes a significant unexpected change in vehicle ride height may affect vehicle handling and safety, and I believe NHTSA should determine whether similar failures are occurring in other early-product
