Hello chark86,
Lots of people with the same issue on this forum thread here, the last comment seems to be the best solution.
The last post on the Pacifica forums.
“I had the same issue. Went to “Apps” on the infotainment screen. Then clicked “All” on the top right. Scrolled through apps and clicked on “Stored Notifications”. When I was there I noticed there was a notification from Sirius and deleted it. Seems to have solved the problem.”
