Not sure if this has happened to anyone else, but about 1/2 of the front underbody aero cover came off my car while driving home on the highway today. Thankfully, it did not hit anyone behind me or cause any accidents. I haven't scrapped the underbody on anything, but what's left is waterlogged, likely from the recent rain/sleet/snow and water on the roads from snow melt. It's part #4 in the parts diagram below. With any luck the service center gets the part prior to my appt.
