What 70 owners told NHTSA about the 2023 Rivian R1s Bev

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.

I am experiencing an ongoing and unresolved steering column defect in my 2023 Rivian R1S, which creates a serious safety risk while driving. Issue Details: The steering wheel drops unexpectedly when weight is applied, even lightly. This occurs both while the vehicle is stationary and while driving, including when hitting small bumps in the road. The issue compromises steering stability and could lead to a loss of vehicle control. Repair Attempts & Rivian’s Response: I have taken the vehicle to Rivian Service Centers four times for this issue. Rivian has replaced the steering column three times (May 2024, July 2024, January 2025), but the issue persists. Rivian has now claimed this is a "normal characteristic" of the vehicle, despite previously acknowledging it as a defect and attempting multiple fixes. I requested a written statement regarding their refusal to fix the issue further, but they have not responded. Safety Concern: My father currently drives the vehicle, and I am deeply concerned that the steering column could fail while he is driving, leading to an accident. The steering instability may cause loss of control, particularly at higher speeds or in emergency maneuvers. Rivian’s failure to fix this issue despite multiple repair attempts indicates a potential systemic defect that could affect other Rivian R1S vehicles. Requested Action: I am filing this complaint to document this safety hazard and request that the NHTSA investigate whether this defect affects other Rivian vehicles. Given that Rivian has failed to properly address this issue, I urge the NHTSA to take action to ensure driver safety, including a potential recall if necessary.

Low Tire Warning either failed or is defective. On Dec 11, 2023 my rear tire went flat (to 4 PSI) while driving on the freeway. I was driving for about 25 miles on the freeway when the Rivian R1S truck kept swerving left and right between the lane markers like the lane assist was malfunctioning. Another driver pulled up on the side of me and got my attention by honking their horn to let me know my tire was flat. At this point the rear passenger tire was dangerously low. There was no warning message on the dash that my tire was dangerously low. This could have resulted in a serious accident simply because I was not given proper warning about the tire pressure. I believe that the tire is defective, so had the truck towed to a tire shop to inspect and replace the tire. The truck is about 30 days old with 1,801 miles on it.

Vehicle lunged to the right without any driver input. Damaged rim and wheel and could have hurt someone . Have never experienced anything like this in my life. Steering wheel was perfectly straight but vehicle lunges to the right. This is a safety issue.

Steering wheel was angled when the car was going straight Vehicle felt unstable going into turns and would pull toward the center line in the road Upon inspecting underneath the vehicle, the steering rack bolts were loose and the rack moving side to side making the steering inconsistent and loose.
