3 warnings are displayed when cold weather arrives. When the car warms up, the warnings disappear.

I get blind spot monitoring malfunction messages in my info display it seems to act up when I start it up cold and it's really cold outside it's happened twice but as soon as I shut the car off and start it back up the messages are gone. I would take it to the dealer but they don't open until 9 and I'm not going to leave my car running for two hours just so they can verify my complaint.
