First Honda in the family and I love the car. I noticed this noise today and since it's Sunday, I wanted to see if anyone had any ideas before I brought it into the shop. Kind of bummed being it's only 4 days old with about 350 miles on it. Sounds like it's coming from the drivers side rear wheel well, metal on metal scraping, not consistent with every wheel revolution.

Sounds like something may have hit and bent the rotor shield. I would, if you don't want to take it to the dealer, is remove the wheel and inspect the rotor shield and look for points where it is contacting the rotor.

 

I also own a 2018 accord and don't have this problem. I would try to engage and disengage the parking brakes and/or brake hold to see if its a problem with those. If not, I would bring it to the dealer to look at it.
