Gotcha, thanks. That’s what I was looking for. Seems like the dealer fixes (as far as the sealant goes) is due to them just being bad at putting the sealant on. Also seems like it works way better when done by the owner themselves. I just didn’t know if I was missing something with the sealant itself having some property to it that makes it not work right. But again, seems like it’s the quality of the sealant installation that is mostly to blame. Thanks for the replies!

Can someone explain why it’s so common for the sealant fix to not work? You’re literally plugging everything with sealant, it makes no sense. I can see maybe after some time the sealant shrinks or cracks, but what about this example where they do it and it fails the test right after?

I dropped mine off, but others have said not long at all. The labor on my service ticket was 20 minutes.

TSB # 20-NA-221.

That link I just posted has the bulletin number.

The fix came out last Tuesday. A few of us in this thread (myself included) have received the update at the dealer and it is now fixed. https://www.gm-trucks.com/2021-silverado-sierra-infotainment-system-fix-now-available-at-dealers/

Hey everyone. I picked up my 2021 Trail Boss two weeks ago. It's equipped with the power open & close tailgate (not just the power release). This weekend I noticed the tailgate was loose when it was closed, so I cycled it open and closed, and it fully latched like it should. I tried it again, and it latched, but it failed to pull in to the second latched (tight) position. You can hear and see it try, but it fails. It has continued to fail since, even if I close the tailgate manually. With the tailgate open, I can use my finger to press the latch into the first and second latched positions, it just won't completely do it when actually closing the tailgate. Has anyone else experienced this? I'm calling the dealer later, but figured I'd ask here as well.

Amazon app problem? I’m not exactly sure what that’s referring to, but whatever it is is not causing OnStar data usage to fail to load or preventing any GM app from downloading or preventing my app from connecting to my truck. All those issues were resolved with the radio update described in the TSB.

Picked it up and all is well!

Mine is there now. Haven’t heard back yet. I basically had to convince them there was a TSB for it and they still didn’t seem to care what I had to say. Guess I will call.

Did they seem receptive to you knowing about the fix already and having the TSB #? I told my guy all about it and he’s like “I don’t need that, they will just see what it does and then see if there’s any TSB that describes your issue.” Um, there is and I’m holding it in front of your face.

Would you be able to post the part number just to confirm which the latest is? I read through a bunch of posts and between the different part numbers and the change in the style of plastic I couldn't decipher which was actually the latest.

Same here. Appointment on Friday.
