Final update that may help some and infuriate us all: Local glass guys got together, some of these guys have been doing this for 30+ years, and studied the aftermarket window from ATI. They actually got two of them in. They said it is not a solution and there were a number of reasons why. Advised me to avoid that route. Some of their techs have been doing these repairs for GM dealers and have relationships with upper management at GM. The word from GM is that they are very aware of this, but they have no intention of making a permanent fix at this point. Its TSB sealant, then replace glass, then sealant, etc. Until the owner is out of their 36K bumper to bumper, then they are holding the owner responsible. This may change, hope it does, because it is not a good look for GM. This glass company said they were shocked at GM's position and they will not buy any GM product for their fleet simply due to GM's handling of this issue. They also work on other brands and other brands are having similar issues, but they are being addressed properly (Tundra, Ford, Ram). Basically, if you aren't already aware, GM does not care about their consumers. Lastly, their best tech that has done dozens of these repairs, advised the most successful repair is to replace the glass and at the same time to perform the TSB sealant. It adds some structure and stability, but is still only a temporary fix but should last longer. Their next advice, once you are out of warranty, is to simply install fixed glass or trade/sell.

Unfortunately, since I learned of this issue all of 3 days ago, I have reached out to 4 of my buddies and my father who all have 2019+ trucks with sliders. All of them, except my dad, have leaks that they were not aware of until I explained this issue. Been driving around leaking water unknown for months and years, just as I have been.

I spoke with him this afternoon and the new glass was delivered to them today. He did not go over part numbers, but did mention the manufacturer was ATI. I believe they produce OEM for Chrysler etc. and aftermarket. So it is indeed different than the OEM GM glass. They are bringing in their tech managers to all put their heads together. He said I had evidently opened a can of worms, some of their techs are brought in by dealers, some of them do no work for dealers. Several techs in rural areas were well aware of the issue and have worked on dozens for GM dealers. The company owners now are considering not touching any sliding windows unless under contract from GM. They don't want the liability to fall on them if someone comes directly to them, bc if the truck is less than 3 years old, they order OEM glass, which we all know will just crack and leak eventually. Anyhow, they are going to study the aftermarket slider and compare it to several OE GM rear sliders and advise me after they have done so.

All, I have followed this forum over the years whenever issues came up. Had two 2017's with nothing but issues and up until last week, no major issues with my 2020 at4. That is when I noticed old water trails on the inside of my rear glass. Straight to the carwash to verify, and sure enough I have 6 or so cracks in the window frame and its obviously leaking. In my line of work, I have a client that owns a local glass repair company. I gave him a call to check the aftermarket for a replacement window, because I do not want to deal with my dealership for many of the reasons listed in this forum. He actually found an aftermarket electric slider available for our trucks. It is a non Fuyao make. They have ordered it and will inspect it, then advise me on the best course. Just wanted to give everyone here a heads up that there is an aftermarket option. Yet to see if it is a better option, but its an option, nonetheless. I will most likely go with aftermarket glass and pay them to repair, rather than screw around with my local service department, which sucks, at best.
