Anyone w/ Alldata Subscription, can you check for PIT6032C (is a subsequent revise to PIT6032B published on Nov 3, 2023). The C version is not yet avaiable on NHTSA.gov web site...


Possibly just adding to the list of affected vehicles?

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?

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.

I’m still on 171, I get the audio dropout, but now it’s more like 30-40s after startup vs right after it. That said, I’ll take it vs the blower slowing down.

Unfortunately this has become true for me as well. A few audio drops vs. the A/C not running when it should is manageable!
