Push Button Start won't let me take control.

Tried that. Didn't work for me. I am excited about the start button press etc..

Has anybody had any luck figuring out what the problem to this is? My 2021 GMC Sierra SLT has started doing this in the mornings.

Did you see the TSB I posted earlier in this thread? Knock on wood mines been fine so far.

Sorry for my ignorance for what may be a stupid questions but what is TSB? Technical Service Bulletin? If so, what exactly did the dealership do to fix yours? I tried the “cheat code” and it worked fine but it’s been doing it the last 3 days for me. Typically in the mornings and throughout the day it is fine.

Can you repost it? I saw THAT you posted there was a bulletin, but I'm not seeing details of the bulletin itself from you...

It wouldn't let me quote, but there's the technical service bulletin.

Thanks for this! I scheduled an appointment for Thursday with my local dealership. Did you get charged for this? My truck is out of warranty at 51K miles but I did purchase an extended warranty. Rep quoted me $200 just for a diagnostic… Hopefully this is an easy fix.

I bought mine used but the dealership took care of it for me.

Unfortunately it is not an easy fix and you should not be charged for this known issue. GM has dropped the ball on this. It will take something more, I fear, before we get them to take responsibility for this.

I know you have been dealing with this for 2 years. Have you gotten yours fixed? Does it happen to you every single day or does it go away for a while and comeback? 

[MayorMike]

If it happened every day they could probably find a solution. No, it just happens at the most inconvenient times. It is generally after a remote start so it occurs more in the colder months. But I have had it happen other times as well. It is a known issue to GMC but they leave it to the dealerships to find the answer. This is something the company should be troubleshooting and fixing. Mine started under the original warranty and I have an extended warranty as well. I feel for those who have had this begin after the original warranty. It is still not fixed even after the replacement of the BCM and various other items. GMC tried to close the case earlier but it is not closed with me. I am waiting to hear from my dealership (who are as perplexed as I am) to see if they have received any help from GMC. I fear the next step is my attorney. I am very sorry for your issue. It takes a truck that you love and makes you question its reliability every day. I can tell you that sucks!

I used the truck over the last 3 days. Went to use it today and completely dead. I had to use the key in the remote to get in so I could open the hood. Dead as a doornail. I'm at the end of my rope. I've been a good guy about it but I  am realizing I am wasting my time. No one is taking this seriously. I am after almost three years of this crap.

Hey Mike, sorry you still have to go through this. Just thought I would update you, not sure if this fixed the problem for me but my truck has been fine for days now. It seemed to me that the truck was in “learning mode” and the cycle never finished which is why it wouldn’t start at times. I figured out that “cheat code” of holding the start button is the way to get out of the “learning mode” so what I did was looked up a video on how to program the remote. You have to insert the key manually and turn it clockwise 5 times. When I did this in the dash it went straight to “ready for remote 3” it didn’t start learning cycle from the very beginning. This is why it lead me to think that the whole time the truck was in “learning mode” but never finished. I kept trying and eventually the cycle started from the beginning. You have to turn the key counter clockwise 5 times the dash while say “learning mode” you press the start button and wait ten minutes and repeat three times. By the third time you place the remotes in the center console. Once the dash says “ready for remote 3” you press the start for 12 seconds to exit and finish the remote learning process. Once again, not sure if this fixed it for me but it makes sense from my thinking and my truck has been fine ever since. Hope this helps

Right now the truck is completely dead. I put a trickle charge on it and the lights would randomly flash about every 30 seconds. I put a full charger on it and it immediately triggered the alarm. I hit lock on the remote. Everything is crazy saying service the power steering,  lower the driver window, service power brakes, etc.. I  figure this is due to the drained battery. I put the charger in start mode and let it go for a few minutes. I pushed on the brake and pushed on the start. The truck tried to start but pushed the brake pedal back at me almost immediately and died. The only good news is it is happening at my house so at least I'm not stranded. The good news for many of you out of warranty is that those of us who have been dealing with this while it was originally under warranty are just as screwed.
