I bought a 2017 Toyota Yaris Ai four weeks ago. Yesterday I noticed the passenger side view mirror cover was gone. I had no accidents or incidents. I'm assuming it popped off when I was driving. I went to toyota they are so far making me pay for the part. The parts clerk told me it would be in the next day, today. This morning he tells me its going to be 5 days. I hate driving my new car with all of the wires and bulbs etc being exposed. I'm hoping all the moisture that's getting in there doesn't affect it or cause premature rusting etc.
