2023 Rivian R1S

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.

The vehicle experiences recurring, uncommanded high-speed steering "lurches" where the Lane Keep Assist (LKA) system initiates aggressive, sudden steering inputs at highway speeds (65+ mph). These inputs force the vehicle out of its lane and require immediate, significant manual driver counter-steering to prevent collisions. These events occur without warning, despite no perceived environmental triggers. This issue involves the vehicle's automated steering and Lane Keep Assist software suite. This safety defect renders the vehicle inherently dangerous to operate at highway speeds for the driver, occupants and everyone on the freeway. This issue is not isolated to this vehicle; numerous owners have reported identical, terrifying high-speed steering shoves on public forums for over a year. There is credible evidence indicating that the manufacturer's executive leadership, including the CEO, has been aware of these fleet-wide issues for well over a year. Despite this knowledge, the manufacturer continues to characterize these life-safety events as "Operating as Designed" or "No Fault Found" (NFF). This issue has been reported to the manufacturer’s service center repeatedly over several months by myself and other owners. Despite the manufacturer claiming to be "diagnosing" or "duplicating" the steering failure, telemetry data from the vehicle (including odometer audits) confirms that the vehicle remains stationary at the service facility for extended periods with zero diagnostic miles driven during these "repair" attempts. Other service appointments show minimal miles driven. The manufacturer has replaced safety-critical steering hardware, including the steering column assembly, without resolving the persistent software-driven steering lurches. The manufacturer’s refusal to acknowledge the defect or conduct meaningful, speed-appropriate road validation, despite being notified of the systemic safety risk, suggests a failure to address an acute life-safety hazard.

While driving at city speeds, I heard a rubbing/grinding noise from the right rear of the vehicle and noticed that the suspension no longer felt normal. After stopping to inspect the vehicle, I found that the right rear wheel had shifted rearward within the wheel opening and was contacting the wheel liner. The condition appeared suddenly without prior warning messages or warning lights. I do not recall any curb strike, pothole impact, collision, off-road event, or other significant impact prior to the failure. The vehicle was towed to a manufacturer service center and inspected. The manufacturer determined the damage was impact-related and not covered under warranty. Recommended repairs include replacement of the right rear knuckle, upper longitudinal link, toe link, hub bearing, and halfshaft. The failure resulted in a significant change in rear suspension geometry and raised concerns about vehicle safety. The damaged components are currently in the possession of the manufacturer service center and may be available for inspection.

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 received a critical safety recall regarding side air bags from Rivian regarding my 2023 R1S on June 14. After multiple attempts by me to connect with their Customer Service, I was informed that a mobile service technician would come to fix the issue on August 26, 2024. This would be more than 60 days after Rivian's initial notification. Additionally, on July 6 2024, when I turned on the vehicle, I was notified of multiple system failures. I promptly created an incident ticket with Rivian on this but have to yet hear back from Rivian. Rivian's lax attitude on getting such critical issues fixed is of great concern. The vehicle is barely over a year old since I have owned it and I feel distrustful of this company and thoroughly disappointed by their nonchalant approach to getting these critical issues fixed.

(1) Q: What component or system failed or malfunctioned, and is it available for inspection upon request? A: "Critical Battery Issue" + "Electrical Hazard Possible; Drive to service center immediately. Avoid driving through water" + "Coming to emergency stop soon; Steer to safety and park" (2) Q: How was your safety or the safety of others put at risk? A: (1) The car abruptly stopped near a corner in middle of street blocking the street, police had to intervene with traffic *potential for collision/pedestrian strike (2) The car had no electrical, completely blacked out and HAZARD lights didn't work when Police asked to turn them on, nothing would turn on **potential for collision (3) Car was blacked out with all windows down, doors unlocked and unable to get into compartments of vehicle to remove personal items of value due to all electrical being backed out *potential safety / theft concern Police ended up towing due to Rivian being unable to locate a tow in a timely manner the incident occurred at 4:30pm and Police politely waited for Rivian until her 6:30 and then called their local tow yard for secure space for unresponsive unit blocking street (3) Q: Has the problem been reproduced or confirmed by a dealer or independent service center? A: Not sure - It took Rivian until 11:30am the next day to coordinate a pick up from local tow yard where Police mandated tow due to Rivian being unable to clear a hazard blocking the street (4) Q: Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? A: The local Police were on scene and were highly accommodating directing traffic to mitigate any potential safety issues for pedestrians, drivers and on-lookers. Rivian hasn't shared anything at all and its 24hours+ after the incident (5) Q: Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? A: Yes, as listed above in #1
