As an update, I just got back from a service center appointment in Glen Burnie, MD. I am disappointed but I can see where Rivian would say what they did.
Apparently because I have a radar detector power cord running past the rear view mirror cover on the window that it is my fault the auto...
I’ve had some issues when the front proximity sensors have crud on them. In my case, it was built up snow and ice from the road. Are your sensors clear of any debris? I also had the warning on my dash for them. Cleaned them with a glove and it worked again.
