Everything on the infotainment system works except for the "No XM Signal" message.

Check the antenna on the roof. It unscrews and may have come loose, reducing reception.

You can try that, but I think that's for AM/FM. XM and GPS would be part of the base. It could be the antenna module or the radio module. The dealer should have a troubleshooting tree that would guide them though that.

I wasn't sure if the antenna mast was part of the XM receiver but it certainly won't hurt to check this connection.
