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 & Rivians 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. Rivians 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.
