On Monday, December 11, 2023 Myself, my girlfriend, and our two dogs were headed across the I-182 bridge coming out of Pasco, WA to Richland, WA. We were in the far left or center lane (I am not sure which). The highway is three lanes each way. We were at highway speed (the speed limit is 70 mph). About ¾ of the way across the bridge, the vehicle felt like all 4 wheels locked. The vehicle then skidded, turned 90 degree towards the concrete bridge barrier. We struck the bridge barrier nearly head on. The vehicle then rotated off the barrier and landed upright in the far right lane. Airbags fully deployed. There were numerous witnesses who reported seeing what looked like the vehicle’s wheels lock and then the events as described. No other cars were impacted. About 20 minutes prior to the crash I commented that the vehicle alignment was off. I had to keep the wheel at 10:00 or 11:00 for the vehicle to travel straight. I found that odd as the vehicle alignment was fine prior to that. Everyone walked away from the accident although both us were injured.

Passenger airbag sensor does not detect passenger reliably. My 13 year old son and my wife both have issues. They are both over 120 lbs, so I think they should trigger the sensor. I have had it serviced for this issue, but it did not fix the problem. It also will detect a person in the seat during a drive and turn off later in that same trip without stopping the car. It seems to me that the sensor needs to be more sensitive. And, once it detects a person in the seat, it should keep the airbag on until the car is stopped and door opened. My wife does not feel safe in the car as it stands now.

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.
