In the R1S, there is a crossmember for the 3rd row seating. On low VIN vehicles, there appears to be a trend, including mine personally, that have crossmember bolts that were mis-installed during assembly and have disconnected the threaded inserts from the body and remain unscrewed and loose. This is a primary mounting point used to secure the seating in the vehicle. The service center confirmed that this has occurred and a video was provided to Rivian when requesting repair. (This video is no longer accessible in the app) Rivian’s stance is that contrary to online reports of similar issues on low VIN R1S vehicles and mine, this is caused by the end user. Given the number of occurrences, this appears to be a faulty installation issue from unskilled labor.
