Not a rivian owner yet, but my experience in my jaguar i-pace is very similar. Range drops by as much as 1/3 in the winter, and ice does sometimes accumulate and block the radar. It also has retractable door handles that can freeze sometimes. So yeah, that all sounds pretty normal and expected.

Very interesting comments, thanks so much for everyones thoughtful inputs. I have read comments about tires as well, I keep switching from the stock 21 inch (best range) to the 20 inch AT for better winter grip, but think maybe the best idea is to buy proper 21 inch winter tires and switch them out each winter. Any thoughts? The only connection to the slippery winter roads is the tires. Winter driving is a issue for EVs.

Yes, if your main reason for wanting the 20" AT tires is winter traction you will be better off with real "3 peak mountain snowflake" rated dedicated winter tires.
