TSB Number for wind buffeting in Yukons/Tahoes?

[jkomlos]

Hi everyone. Sorry this is my first post, as I understand it is a sensitive topic. I am looking at a 2016 Yukon Denali and it had the dreaded pressure issue. I was trying to explain to the dealer that there was an issue with these and gave them the TSB # I saw here, but it isn't pulling up anything for them. I had found PIT5318B, but GM customer service doesn't recognize that. Do we know what the correct number is?

Thanks in advance.
