Just got my Yukon last week and I'm having the same issue. Going Monday fingers crossed they can do the above without issue.GMC dealership near me couldn't find that TSB# on my Yukon. The manager says he knew what the issue I was talking about yet couldn't see any reports on it. Setup an appointment for them to look at it next week, fingers crossed.
I brought my '22 Yukon to the local dealer this morning to get this resolved per a TSB which was recently published on 11 Aug. I learned about the TSB and the TSB # by calling the dealer I bought from (but is far away from me). Local service advisor had no idea about the issue and wasn't able to find it in a search by the TSB # I gave him. Not sure if he searched correctly or not but we were eventually able to find it. For anyone else trying to get this issue addressed, below is the TSB info. After having this addressed, my lights appear to be functioning correctly now!
