rubicon 2023

I recently purchased a used 2023 Wrangler Rubicon 2.0L turbo and noticed a continuous “da da da da” sound when accelerating. It seems to be coming from somewhere near the pedal. Is this normal? No sound at all when the peal is released. Any one experienced the same?

Hi All, I was putting in a air compressor behind the left wheel well. I took some photos and I noticed later on when looking at the photos, the coolant line has some pink residue on it. Is this a cause for concern? Probably should bring it to the dealer to look at, right?
