My passenger side mirror in my 2018 NX 300 sport was damaged when it was pushed back. The part that is attached to the car is not damage but there is one piece that broke off. I found the piece but know i need to replace it. The first time I went to the dealer they said I only needed 2 parts to fix it. They did not order the part so I had to go back and start all over. This time, they said I needed to replace the whole mirror. Has anyone had any experience with this? I felt like they were not telling the truth.
