Back window rattle is annoying!!!!

[yukonchief]

They did change the glass and frame. Unfortunately the new glass has a scratch and they have to do it again. The new glass still shakes a little. I wondering if the pin is a different size.

Still waiting for the third glass

Sweet I’m right at 35K I might have to take mine before I hit 36K miles and I’m out of warranty

I would see if the can slightly bend the hinge that’s attached to the glass. To me it looks like a slight angle bend will sort of fill the hole artificially if you will

In addition there seems to be a little more space on my left hinge. I’m going to ask them to add a rubber washer or O ring to fill it in.

Truck went back to the dealer yesterday for another replacement glass. The first replacement had a small scratch. The dealer was very good about it and ordered the glass on their own and told me they were going to replace it.
The second repair appears to have worked pretty well. The amount of shift is almost nil.

Here it is, a couple of days later, I heard the rattle again. Kind of surprised. When I stopped for gas, I opened the window to check things out. I found all FOUR nuts that hold the glass to the hinges on their last threads.
I am not happy. I hand tightened them and will be at the dealer first thing in the am.

What are you all doing to solve that little back window rattle that goes off every now and then on certain roads? I bought a used 2017 Yukon and noticed this on some roads only but it’s annoying. Thanks for the ideas

Has anyone solved this problem yet? I have a used 17 Yukon with the same type of rattle that is coming from the spoiler area. I believe its the plastic vibrating into the metal parts but I have not taken it apart yet. Does anyone know if I can just pop the top plastic piece off of the spoiler or do I need to remove it entirely first?

Open just the rear window. About 3/4 full. Grab both sides of glass and see if it moves side to side. The glass should not move. The last time the nuts on the hinge were loose. We also tightened up every screw etc on the spoiler trim.

They replaced 2 rear glasses.
I think that the holes on the hinge are just a little too big or the pins are a little too thin.

Well I decided since I’m still under the bumper to bumper warranty to take it back to the dealership and have them fix it before my warranty goes out. I’ll report back once they give me a dignosis on this problem.

Quick update: they tell me the noise is coming from the second row seats and not the back window. They said when the seats are down the noise goes away but in the up position is where something is rattling. I always heard the noise coming from farther back but if it’s what they say then oh well, hopefully they fix it. I never tested this as my I never had a reason to put the second row seat down because it’s always needed. My Yukon is still at the dealers so this is what they said for now looks like I won’t get it back til about Monday or Tuesday.

Did the seat idea end up being the issue? I have a rattling problem that I can't figure out. I think it is from the glass on the hatch (seems kind of like glass on metal rattle). I've tried putting felt tape on basically everything that the glass would contact, but I can't seem to fix it.

Make sure that your tire wrench and jack tools in the compartment on the rear driver's side is secured.

I did check that. I think I finally found the culprit, after adding felt tape all over the place. I think it was at the very top of the glass where it connects to the plastic "spoiler". The left side was solid, but I could play with the glass to make the very top right come slightly away from the spoiler. I added a couple small pieces of felt tape between the glass and spoiler, and that seems to have done the trick!

My passenger side rear seat has a rattle sometimes. Did they resolve your issue?

I, too, am experiencing a rattle coming from the back ('16 Suburban) and I don't even know where to start. It doesn't seem to be coming from the rear window, but more like the rear passenger side door. Wondering if it's seat related like a couple folks above seem to be experiencing. Whatever it is, it's driving me nuts.

Any chance that you would upload a picture showing what you did? I've had the same issue on 2016 Tahoe and it's driving me crazy...I've tried everything.

I have the same issue on my 2016 Tahoe. Looking for the best solution as the dealer never finds a problem.

Just tried this. I will know when we drive to dinner.

A little better, but not completely fixed. More padding and driving today.

Unfortunately, I spoke too soon. It was similar to what DCmaynor did. Mine wasn't that extreme.

My issue seems to be really hit or miss. This weekend it was rattling like crazy, and then today it wasn't making any noise.

Mine is kind of similar to this. Sometimes I swear it is the glass, but at other times it sounds like it may be near the passenger door. I know there was a TSB about some metal tubing in the rear passenger wheel well. I took out the liner and added felt tape in a few spots where the the tubing was touching, but it didn't solve anything.

My next plan is to take off all of the plastic on the rear hatch and see if it has anything to do with some wires hitting the metal (kind of at a loss at what could be causing it at this point). I have added felt tape pretty much all of the way around the window. I know there is a gap (can move slightly) on the pegs that keep it connect. I'm thinking that this probably isn't it, due to the fact that it shouldn't move much when the window is closed due to the latch and the rubber likely holding it in place.

I am not looking forward to taking off the plastic on the interior on the rear passenger side, but that may be the next move if it isn't fixed when looking at the hatch. This is probably the most annoying thing in any car I have ever driven.

Did the additional padding help? If so, I may loosen the window in an effort to stick padding/felt tape all around the window.
