2018 Model S 100 - SXM updated channels several months ago and a number of channels changed locations. One as an example is the Escape which was previously on Channel 69 but was moved to Channel 149. My Model S still shows the artwork for Escape on channel 69 but plays the Broadway channel music. If you try and tune channel 149 there is no such channel. I’ve worked with SXM Tech Support and they’ve tried multiple update cycles, disconnecting and reconnecting the radio and nothing corrects the problem. It’s clearly a Tesla software problem as it relates to their SXM load. I’ve tried making an appointment with service and every time I define the problem they tell me it’s SXM’s problem. How do I get their attention so they will elevate the problem with Tesla to get them to update their software.
