I have had this problem for over a year. Finally after getting frustrated and left stranded because battery went dead over night and vehicle had to be jumped to get started. i had the bypass wire put in cause GM dealer said that it is not a factory problem and I would have to pay to have it fixed. Vehicle is a 2019 with only 22,000 miles. The bypass is working great so why spend the money. Why are the complaints on here so many if the problem is not a factory defected part.

My wife's Blazer did this and they replaced the whole shifter assembly. Two weeks later we had to take it back and found the battery was in need of replacement because it was affecting the backup camera which was having issues the first trip to the dealer. Check your battery if it is older than 3 years and make sure it isn't the culprit.

My 2019 GMC Sierra started with this issue several months ago.  Problem was very intermittent.  Some days it would alarm for up to 30 seconds.  Other days never had an issue.

After lots of research and seeing many comments I solved the matter today.

 

under the steering column is a small switch which should be closed when the shifter moves to mark.  This switch seems to be made of the cheapest parts available.  
 

Remove the 7mm bolt under the column.

Turn steering wheel to the right and you will see a 2nd 7mm screw.  Then back left and remove 3rd and final bolt.

at this point you can pull out the bottom half of the steering column off exposing the switch.

 

You will see 2 black wires connected.   I soldered a small jumper wire across the 2 black wires.

put everything back together. 45 Mins including a test drive.

Problem completely resolved.

 

if you wish to order a replacement part another posting listed it as. GM 84800776.  I have not verified the part as accurate.

 

Good luck with your repair.

They don't sell the switch.  Its part of the shift control.

Hello, new to the post.  Had same issue with 2019 Sierra Denali, 70,009 miles, took it to dealer, they had it 3 days, said there was a service bulletin about corrosion on transmission ECM.  Cleaned wires and put dielectric grease on and they said it was fixed.  Drove it home and as soon as I turned off truck, the shift to park message came back.  I immediately pulled the column apart, removed the switch, wire nutted the wires together and it went away.  Will order a new switch tomorrow!  Thanks for all your help.

2019 Sierra Denali, same issue.  Dealer had it 3 days, charged me $170 and it didn’t fix the problem, they said service bulletin about corrosion on transmission module wires.  As soon as I got home and turned off truck, message happened again.  Took apart column, removed switch, wire nutted wires together, problem went away.  Will order new switch tomorrow, thanks everyone!

@GMCustomerService is there a timely solution to the shift to park error message?  

 

I brought my truck (2022 GMC Sierria 1500 Denali) to the dealership to remedy the problem, I was told replacement parts are in short supply and would take months before they are in stock.  Please advise a better solution.  

 

Looking forward to your response.

Had the same problem on my 2019 GMC Elevation.   I cut the wires to the switch under the steering column and spliced them back together basically eliminating the switch all together.   Haven't had the message return since I did this.  GM won't acknowledge the problem.   It should be a recall.

Follow the instructions above on how to remove the steering column.   Then cut the 2 wires going to the switch and splice them back together.   Essentially you've eliminated the switch.
