High Pitched Whistle under Dash

Nothing. I think I've grown to ignore it because I don't notice it anymore unless I specifically want to listen for it.

Just want to see if there's any updates as i too have the same issue on my 2021 6.4L. Its been to the dealer a few times now and they have acknowledged the noise. They changed my steering gear twice and that didn't fix the issue. They've been in contact with the chrysler techline and still have no solution. I mentioned the hose liner issue but was told they cant change it without approval from chrysler. I'll have my truck back at the dealer in a few weeks and will have them look at it again.
