Dealership updated mine from Y172 to Y175 and everything is fixed. No more crackles.

Excellent!

Thank you for replying. I have sent you a detailed email explaining the issue along with an mp3 recording of it occuring.

I have the same issue. Recall update installed by dealer Monday, static in Bluetooth calls since then. 2024 1500 AT4.

We were also having the same issue with our 2019 Yukon XL. Replacing the antenna amplifier as suggested definitely resolved the issue. Not terribly difficult to change, basically remove the upper trim, right rear quarter and right rear coat hook and replace the part.

Just to report in, I filled our boot with grease yesterday and the noise is definitely gone. 2019 GMC Yukon XL Denali, 44k miles.
