Tailgate window is loose

[TwinTip]

I posted the following information under "Tailgate window/glass loose" in the Yukon and other large trucks forum. I thought this was a more frequent problem but I've only received one response, for which I think it may not be very common.

 

The window on the tailgate of my 2003 Yukon has popped up completely from one of the hinges that attach the window to the tailgage. Additional information on this subject is shown below (a copy from my earlier post). I need to go to my dealer but because of a bad experience with one of the dealers that I went to, I want to be prepared with as much information as possible regarding what I believe is a defect on the window. Please advise if you have seen or heard about this problem and what I can do to make sure it is resolved by the dealer.

 

Thanks.

 

Copy from my earlier post is as follows:

 

Has anyone had problems with their rear window/glass being loose on one or both of the hinges that hold it to the tailgate? This is for a year 2000 or earlier model.

 

I had a 2000 Yukon and approximately 2 1/2 years after I bought, it I had problems with both of the hinges that hold the glass to the tailgate becoming loose. One dealer told me I had broken it and another dealer accepted the fact that this was a defect and replaced the glass.

 

Now I have a 2003 Yukon and again, at approximately the same timeframe after I bought it, one of the hinges that holds the glass to the tailgate is completely loose.

 

I have less than 25k miles on it and park under a roof about 80% of the time. I don't think the sun is an issue. Both vehicles have been meticulously maintained. I also don't slam the doors or tailgate so it is definitely not because of abuse.

 

I have searched for service bulletins, recalls, etc. but have not found anything that relates to this particular subject. I am also preparing to go to the dealer and need as much information as possible. Any help will certainly be appreciated.

Yes, we see this failure. I wouldn't call it common, but we do maybe one a month, perhaps a bit less than that. There are no TSBs that I'm aware of.

Thanks for the response. I have one more question. I have a GM rear wind deflector. Do you recommend I remove it before taking the truck to the dealer? I want to avoid any problems replacing this part and don't want this accessory to be used as an excuse to the problem.

 

This has happened with and without the deflector.

Yep, this happens without anything extra added to the hatch/glass. If you can take it off without leaving holes or other obvious signs that something was mounted, it's probably a good idea to remove before going in.

I took the truck to the dealer and they immediately recognized the problem, what a relief. So the window was replaced and I'm back to being a happy customer.
