NHTSA complaint #11496342

Owner complaint summary

The truck was parked on a moderate slope (maybe 10-15 degrees), on a gravel driveway in slightly icy conditions. After 1-2 minutes in "park", the steering wheel began turning and the truck started moving backwards down the slope. It stopped when I pressed on the brakes. I immediately moved the truck to a flatter area. I was able to reproduce this effect multiple times on similar slopes that day. I would put the truck into park. It would be stable and stationary for 1-2 minutes. The steering wheel would then start to turn and the truck would start to move. The front wheels were rolling. I think the back wheels were sliding, but I'm not totally sure. The truck is presently at the Rivian Service Center being inspected. I've attached a photo of the truck on a slope where I could recreate the problem. There was some ice in tire tracks from the day before, but the truck never lost any traction while driving. I have video from the inside of the steering wheel starting to move on one of these occasions.
