While driving on the highway, I heard a noise.  While still driving, I quickly looked around which included looking in my rear view mirror.  I saw something in the air and saw it hit the road.  It didn't occur to me that what I saw flying was from my car.  I thought the noise was from some part of the object (maybe a screw) hitting my car.// When I got to where I was going, I walked from my driver's side around the back of the car looking to see if there were any noticeable issues.  When I didn't see any issues, I decided to walk to the front of the car where I noticed the panel missing between the top of the front windshield and the sunroof. // I found the following article: https://www.carcomplaints.com/news/2021/mercedes-benz-sunroof-problems-cause-recall.shtml The scenario described in the article happened to me on Saturday 27Aug2022: "And a 2015 Mercedes C300 driver heard loud wind noise coming from the top of the vehicle near the windshield while driving above 40 mph.... while driving on the freeway the driver heard a loud ripping noise and realized the panel was missing.
