hi - i have experienced the same issue - right front wheel screeches kinda noise. The first time I pointed it out to the dealer, they checked and said it was a stone stuck in the disk, but with the way the noise was "behaving" it seemed more mechanical and wasn't a permanent noise. Happened randomly and often when turning left, which puts pressure on the wheel at an angle. Dealer turned me around a few times after that because they couldn't replicate the noise when in their hands in the shop. So i was finally able to record the noise on my phone (had to turn the Bluetooth off because it wouldn't pick up noise otherwise).
Dealer / shop guys then were able to identify that when the brake disk wears, it leaves a film of metal dust that creates friction with the drum casing - apparently a "defect" that will need to be corrected. So every 3 months or so, the noise reappears, and I have to get the car in to clean up that metallic residue. I was told there is of no safety concern. They will eventually have to find a permanent fix to this - it's just that when the noise appear, I see heads turn to look at which klunker car the noise comes from. A bit embarrassing since this is a new brand. I will update as things unfold - unless someone else comments with a solution.
