Friday, I went to move my truck out of the garage and after I started it, I could not move the shifter lever. I tried adjusting the steering column and wiggling it around and no go. I then shut the engine off and got a message shift to park. I still could not move the shifter and when I opened the door, the system would not shut down. I had to unhook the battery. I let it sit with the battery unhooked for an hour and tried again, still no go. Right now, it is at the dealer, and he cannot look at it for a few days. Anyone else had this happen? I did a google search and it seems like this has been a GM problem for quite some time with various causes. Truck is a 2019 Sierra 1500 with only 19,000 miles.
