Greetings to all.. Have trouble with XMSirrus weather app completely loading into my '18 Malibu radio. Different items such as 5 day forecast will only load 4 days and never completes the 5th day. Tried sending new signal to radio and doesn't help problem. Called XMSirrus and they say it sounds like a radio problem??? My Jeep sits next to my Malibu and the weather app works great and there are no issues. Any body else have this problem w/ their Malibu?? Any suggestions other than taking car to dealer?
