So took my 22 Yukon to the dealer for same issue, also advised them of the clamp issue. Tech that worked on it is outstanding.He put a new clamp on it with exhaust ****. And no more issues.

Ever hear back from GMC?
I ended up emailing GMC executive and got a call from their "Customer Resolution Center" within an hour. They asked me to take the car to another dealer which said the same "Nothing wrong with the car". The resolution center called me back and I let them know what happened and that I did not agree with that assesment.

They are supposedly getting in touch with a district manager to come out and see the car. Unsure where this will end.

Is your Yukon diesel? I advised them about the issue with the diesel ones, which has a TSB, and they said since mine is not diesel it does not apply.

Not a diesel, but it was the 2nd time I took it in but went to different advisor and told him about bad clamp causing issue. So diesel is not the contributing factor.

I did that and even printed out the TSB :(. 3 different dealers now and everyone says it's "Normal"

Not normal, I call BS. My 2017 has a similar, if not the exact same, exhaust and never had one leak from that joint. I suspect there was some questionable manufacturing errors that GM doesn't want to eat being an emissions component.

I go in for an oil change/tire rotation Wednesday and plan to bring it up again.

Still working with the GM Executive Referral team. They say the dealer techs that have worked on the car are involved in discussion of what's going on and are aware of the TSB for the Diesel engine. I guess since the Tahoe's don't trigger a service light is probably why it's being ignored.

Supposed to get an update next Monday.
