If it were an XM issue, other cars would be having this problem and it would be fixed. They aren't. Tesla has had major coding problems with SiriusXM for at least a year. If they would put up a SiriusXM page on the web so Tesla users could provide feedback, tesla would be overwhelmed. I figure not many owners who can provide feedback on the issues are important, so they probably don't even know of the issues. Tesla has no "problem reporting" feedback loop for any problems that I am aware of, and frankly, they probably don't care and don't want to know. I am sure the service folks don't want to know. See if you can find a workaround to listen to the channels you want and put them in Favorites, even if they are labeled incorrectly. My 2020 doesn't even show channel numbers anymore, so I wouldn't know if channel 40 is really channel 6.
