2021 Denali OTA updates

[Reddevil96]

I have a 2021 Yukon XL Denali with 9/21 build date. Those of you with a similar build date, have you received any ATO updates since about December of 2021? Dealer I took it to and asked the question said no, but I question the effort the put into the answer.

I thought someone else on one of the other posts stated that GM stopped doing OTA updates on the 21’s due to some issues they ran into with it.

I know with my ‘21 Tahoe, I haven’t seen any updates since something for the airbag. I’d like an update to fix some weird turn signal noise issue where it flashes but doesn’t have the click noise mid-cycle occasionally.

Course right after I posted the last post, my wife’s 2020 Traverse which has the same Infotainment 3 system just received an OTA update today. Maybe there’s hope we still see some updates on our large SUVs.

As of August 2022 there’s supposedly a new software update out that addresses multiple issues according to the TSB 22-NA-127.

I’m not sure exactly what it addresses..curious if anyone is able to find that TSB description.

I'm fairly certain GM has indefinitely suspended OTA updates for T1XX trucks a while ago.

If you search that TSB number you can print out the full PDF.

Yeah I don’t recall doing any ota updates on my 21 even before December 2021 and mine is a 5/21 build date. No issues with my head unit.
