Sirius XM radio in 2018 Forester loses Siruis subscription when car is shut off

I am having this very same problem. It just started around the time yours did. I am taking mine in tomorrow but it doesn't sound like it will be helpful.

The dealership replaced the radio and the issue isn't occurring anymore; however, when I try to use the Info part of the radio, I still receive a message that a Sirius XM subscription is needed. I've verified that the new radio ID is associated with my Sirius XM account. At least I'm able to listen to my Sirius XM stations again.

You will not like this answer. It CANNOT be fixed. It is because SIRIUS added more channels than your radio can handle. I am having the exact same issue with my 2017 Forester XT. I have had my radio replaced and the unit has been "updated" 6 times. Still not fixed. SUBARU blames SIRIUS, SIRIUS blames Subaru. Quite the vicious circle. No one can fix it or is willing to take responsibility. They both are more than happy to take their money, but sure don not want to do anything about a problem they are both well aware of.

I have just experienced the same problem with my 2018 forester but haven't called subaru yet. Doesn't sound hopeful. Hope it is covered under warranty!

It is 11/22/2020 and I have them same problem. When I press list I do not get a list of all the SiriusXM stations. There is a workaround but i would have expected a fix that would allow me to use this radio as the manual states. Get to work Sirius and fix this.

Would you mind sharing the workaround as my Sirius is 100% dead to me. I was driving with Sirius on then it switched to an FM preset and when I go to home and press Audio it shows symbols for all the options, but when I press Sirius it just goes to the preset FM station, like Sirius isn't available on my radio. I'm 4 months past end of warranty.
