Scraping sound when not scraping

Not a problem. I just can't think of too many other places where you can get metal-to-metal contact. If you were complaining about squeaking, clunking or creaking it would be easier to narrow down.

most car issues I've ever encountered are the new ones nobody has ever experienced before. I think this is one of those issues. It honestly sounds like the strut braces are shifting during sudden suspension loading. It's really strange. The car isn't dipping enough to scrape the ground but I keep hearing it. Was horrible when I left the house today. Seemed like it was spreading and my entire front end wanted to fall apart. Feels like I'm driving around a pos. Sucks.

and unfortunately I wasn't able to get the car on a lift to check it out the other day. Gotta run it back to the dealer. Don't trust it very much.

My best guess is the oil pan shroud/cover. There is a big piece of black plastic underneath that covers the oil filter and pan. The screws in it tear out quite easily and there are a ton of them and they are a real PITA. Once one or two of those screws tear loose, that whole thing starts to come loose and sag. If you hit a bump, maybe one side of it is torn out and the bump in the road causes it to scrape. Buy the aluminum one from Z speed? I think sells it.

Quick update for y'all.

I mounted the gopro in three separate locations. Front/middle door/rear in an attempt to see if anything was actually scraping. I also removed the splash guards to eliminate that from the equation entirely. The sound has now spread throughout the entire chassis. It was locally isolated to the front passenger side. Then the entire front end. Now it encompasses the rear end as well. Feels like the whole damn car is coming apart.

I have the noise recorded on the camera and will finish editing and post it tonight. The car is going to the dealer as soon as I have time.

If I get any conclusive answers I'll be sure to post them back here. Thanks everybody.

By the way... The sound can only be heard from inside the vehicle. Thought this was odd but the camera didn't pick up any noises from the outside other than typical road noise. Taking it to the dealer at 2:30 today. We'll see.
