2015 Tahoe AM/FM static in warm weather

[connerja2]

I have a 2015 LT, full stock Chevy MyLink Infotainment radio system. When the outside temp gets higher than 75 degrees, I can't pick up any AM/FM channels for about 15 minutes after starting the engine. I can't tell if it begins to work after the cab temp drops (due to the AC running) or if it has anything to do with the outside body temp cooling off (due to the actual movement of the outside air). Has anyone else run across this type of problem? What was the fix?

** EDIT: The XM and Bluetooth works fine while the AM/FM are weak & static. **

Finally took this to the dealer for a diagnostic check. They looked at me like I was insane. However, the issue was replicated, and the determined that it was the radio itself. They changed it out under warranty, and all is good now. "Crazy!"
