I bought a new 2021 GMC Sierra 1500 AT4 Diesel yesterday and after only having it for not even 5 hours, I went to park in my driveway and had a message "Shift to Park" after shutting it off. I had it in park so I thought maybe it was just a fluke so I turned it back on drove around the block. Came back shut it off and the same message popped up again. It does not turn the dash off so I was concerned that it would drain the battery. I took it back to the dealership and left it there for the weekend and hopefully on Monday they can tell me what happened. They informed me that they never had this issue before... I am wondering if anyone else out there has had this issue?

The only time I get that message is when I shut the engine off in a gear or neutral and open the door.

I get out and close the door and the damn horn will blow twice and lock all the doors minus the drivers.

There is a micro switch behind the lower valance, to the right of the steering column, that gets manually tripped when column shifter is put into Park. Wonder if it needs adjusted or has come loose?

Welcome!

Yea, let us know what the dealer says as well. I've never personally seen that issue myself. I'm sure it's something simple the dealer will take care of for you.

For sure! I had a new '11 Duramax that had about 300 miles on it on the drive home I had an emissions light and had to turn around and go back to the dealer the next morning.. It happens... never an issue after that. :cool:

Get use to it my son in law and I have 2020's GMC 1500 SLT 3.0L diesel, and every other day there Is a code about something, I get service steering column displayed and then disappeared, son in law just got number 2 heat plug code, couple of weeks ago I had P2C7A-00 NOxCatalystEfficiencyBelowThresholdBank1Catalyst2 stayed on for a week then disappeared, if you purchase a good code scanner, you will find there are codes that don't turn the check engine light on. but they are there. GM has forgotten how to make a truck!

Ouch, that's some bad luck for sure.
