2020 RDX with < 15k miles. About 4 weeks ago, a crackling/popping sound started and it is coming where the windshield bonds with the car frame (for lack of better terminology). Initially I thought this was weather related, but it seems that the sound occurs even after 1 hour into a trip when everything should be "warm". I am in Northern California if that matters.

Has anyone experienced this? I don't typically go to the dealer, but will probably do so in order to see if this can be fixed under warranty. Any tips on how to work with the dealer on such a problem is appreciated as well.

Bring it in to the dealer. What your hearing is most likely from the speakers.
If they can duplicate it then they'll replace some connectors and relieve the strain on the wiring harness at the infotainment, amp and tuner.

well, it is the cables from the sunroof frame they never did put a cushion between the Frame, cables that is the cause even if they put a new sunroof frame in the car the problem does come back. It is an know issue that I reported to them 2 years ago , fixed myself .

you dropped your headliner or accessed from above?

No just take a little spray foam to sperate the cables away from the body and top of the frame area.

Hi the popping and cracking is from the speaker, has someone made a fix for this?
