I have 4 of the 6 total (2 out of 3 on each side) that the dealer has ordered for replacement. My dealer said this is a common problem. Hopefully they are doing more than what was done at the factory so that it won't happen in a few months again.

Sorry to be late to this discussion, but got a previously owned Tahoe LTZ with this problem. It's 3000 miles out of warranty so dealer won't fix it unless I pay$$$$. I'd like to replace or repair myself but nowhere can I find the gm part numbers online. Does anyone happen to have these part numbers? I'd really appreciate it!
Just had same issue stopped at truck stop bought gorilla glue (super glue) sets in 10 seconds, 30 minutes down the road and it seems to be holding.Short Fix
I just drove from St. Louis, Missouri to Destin Florida going about 75-80 most of the way there. I heard this flapping sound coming from what I thought was the driver side seatbelt fasten on the wall. Never thought about it being something on the outside. Tonight when my sister got out of the backseat and closed the door heard a sound and looked and see 1 of the black plastic trim piece is not clipped on the top and doesn't line up the same anymore. I'm on vacation for 1 week and then are driving back to Missouri. It's about a 12 hour drive and don't want the piece to totally fall off when driving. Does anyone have a temporary fix to get me back home. Not sure if electric tap that's black would work. Still mad at GM for this poor quality. $74,000 for a Yukon XL Denali and plastic trim falls off after 27,000 miles on the car.
I know I've heard at least one person reference this, however, a couple of nights ago the wife complained about a "new noise" in the LF door/seatbelt area. I drove it - nothing.
She then filmed the noise the next day. Come to find out - it only happens at highway speeds - 70 mph +. Just from the noise on her phone I knew it was some sort of loose part/"flapping in the wind" noise.
All 3 of the left side black plastic trim pieces on the front and rear doors were loose at the top and middle. They used these $.10 Chinese clips fastened to the plastic and then the clip presses into the door. The clip is staying in the door but separating from the trim. I just popped it all apart and siliconed all of them on and they are good to go.
Everyone check yours. Mine is babied - garaged, cleaned every 10 minutes, blah, blah. If mine fell off then any of them can.
