This TSB for Y171 software seems to imply it may have the fix for this??

After driving my rig four about 2 weeks now, after getting the Y171 software, I am happy to report:
No Audio Cutout shortly after startup
Auto HVAC operation appears to be back to normal again...

Autoconnect of CarPlay still hit and miss...
I am sure there are still some bugs...had a "Starting SirriusXM" message happen, but it was rainy with a dense fog; so maybe that was part of the issue...

Did you have to go to the dealer to get this update or did it come over-the-air?

Dealer installed it.

Got it - I'll reach out to the dealer! Can't wait to get this fixed.

Just to close the loop on this for anyone having the same problem - the dealer installed the Y171 update and my audio drop-out issues have not recurred since then. Took about 2 hours at the dealer.
