Thanks, Jim! I wish it were that simple (and maybe it is). They supposedly replaced the port (under warranty), but that didn't fix the issue. Do I try to replace it again? I really think it's something else, but I haven't been able to find any kind of diagram showing how it might be wired differently than the USB plugs in the console to try to track that down.

I have a more uncommon configuration with the folding center console in the middle for a 6th passenger. Apparently, for the 2018 Sierra 1500, this configuration included a 3rd USB port in the glovebox. The glovebox USB port intermittently connects and disconnects when my phone is connected resulting in not being able to consistently use Android Auto apps, listen to anything from my phone, or even use the radio due to the sporadic disconnects and reconnects. My truck's still under warranty, and I keep being told that the glovebox USB port "doesn't support Android Auto" by the dealership, and then that same line is parroted by GM customer service. Does anyone know anything about this or is there a way to get GM customer service to take me seriously and actually do something to help resolve the issue? I've been through multiple new phones, multiple high-quality cables, and the issue is always the same. The ports in the center console work fine, but the one in the glovebox doesn't.
