I have a 2019 Sierra Denali and at around 3 months the navigation started working intermittently. Then my usb port under the main console went out so I used the one in the console until it quit. I took it in for service and they replaced the wiring harness and told me that the fix makes the usb port in the console for charging only. That fix lasted 2 days before all ports stopped working and sd card removed message came back. They also tried to blame my using a magnetic cable which I use on all my phones and cars as it is easy to just slide the phone on the tray charger and it magnetically connects to use android auto. The 2nd time it failed I was using factory samsung usb data cable. Also my whole camera system went to blue screen twice since the 2nd time they fixed it. Now they are going to replace the whole radio and wiring harness including the sd card reader in the console. I am really beginning to reach my wits end and hope this next fix lasts for more than 2 days. They told me they have some bulletins on the usb port issue but I have been unable to find anything on the web so must not have been leaked from any internal sources yet. Anyone have any other ideas for a fix?
