Rear Lift Gate

[MiniMaxNali]

I’ve got a 21 Yukon Denali that I’ve been trying to track down a “creek” noice from the rear window/lift gate every time we go over any bumps in the road.

Took it in to warranty, to issue to find I was a 100 miles out of warranty so they refused to warranty it.

What I was told is the gasket that’s welded to the window is bad and need to replace the whole rear window. But unfortunately it comes as a kit, window&wing combo around $2k in parts!.

To recreate the noice I apply slight pressure on the rear window from the outside. Illl post a video of the noise it creates to help understand.

Has anyone had this issue?

Thanks!

Can you open the window and move the gasket or see where it’s loose? I have an older rig and my gasket is attached to the hatch, not the glass. It may be as simple as gluing it back down. If GM won’t help and you need to replace the glass go to a local wrecking yard to find a compatible window but I’d push on your dealer too.

I don't want to contradict what your dealer stated to you, but it appears that you can purchase the gasket alone, according to GMPartsDirect.com.

Did this solve your problem? Mine squeaks like a ***** on bumpy roads.

I had this issue as well - it's a rubbing noise between the striker on the glass and the latch on the lift gate. I put a bit of Sil-Glyde on mine and the noise went away. Honestly just about any grease will work. GM has a TSB for the issue - https://static.nhtsa.gov/odi/tsbs/2024/MC-11010642-0001.pdf
