Interesting...all the more reason to keep that 10mm wrench in the vehicle somewhere; and possibly practice at home, if you are going to be using Remote Start.
No, he is saying that the bulletin published on Jan 13, 2023 says they still have an issue w/ this. The bulletin number is PIT5873D. I cannot locate a full online copy of that bulletin (Don't find it on NHTSA site yet, or anywhere else for that matter). But, his post implies they have new info saying they maybe haven't got this all the way solved yet. This is apparently a Revision, since PIT5873C was the bulletin which implied the BCM update resolved the issue.
I get that - but has anyone had their BCM updated in the last year that had the remote start issue and still has the issue? I haven't read this entire thread, but it seemed like people that had this issue got a BCM update and haven't come back to say they still have the issue. If BCM updates are cumulative (which by all accounts seems they are) then if he takes it in for the DRL update he'll also get whatever changes they made to fix this issue last year.
Agree, I haven't had an issue since the update...but, @Amandaann said she had it in post 215 and 218 that she doesn't know her build date and hadn't had the BCM update. And @pribilif said he had it and tried to get his BCM updated and the Dealer said to get bent there is no fix (but, I agree, his DRL BCM update would at least get him to the latest version; presumably including the update from last June which was supposed to address the issue.)
I'd just stay off the remote start on this one ... It likely doesn't have the updated BCM software...I do believe the June version "helped" but maybe it didn't get all the way there.

Edit: Going to design something to hold a 10mm box wrench out of sight so not to rattle around....overkill..yes, but why not

It's resolved if you get the BCM update per the TSB. I've not had it since then and have remote started numerous times.
This is so interesting. I have a 23 Yukon Denali 6.2... started getting a Check Engine light a week or two ago... goes on for a couple days... off for a couple days... going to take it in next week.
That is an incorrect decode, there is no High Voltage LithiumIon battery in the Yukon. And, any active Check Engine Light/ECM code will inhibit a remote start. Get it in if CEL is on.
