Yea the trucks being built in august of 2020, mine was 8/14/20 and its leaking on the passenger side, waiting for my first service appointment yet.

Is the frame leaking from cracks? If you push up on the headliner you should be able to see he cracks. Just wondering if your issue is the spoiler bolts or cracked window frame.

Keep us updated. I thought they fixed it for 2020, apparently not.

Just noticed the back seat brackets are rusting on both sides.... OMG $^%#! $&#&^!$ !!!!!!!!!

Or is this a feature enhancement ?

Any one else having this happen ????

I wedged a small towel between the upper back of my seat and the window where it drips down for this very reason. I can’t get the dealer to actually fix the leak so I’m just keeping it from getting my carpet and hardware wet. Good enough for now, I guess.

I have paper towels there on both sides that I check once a week or after big storms. But that still hasn't helped this issue.

If the dealer can't fix mine or won't maybe I'll hang a small potted fern below the drip. At least the water won't go to waste.

For my bigger leak, I'm thinking of something like this, but inside the cab.

Brilliant! My wife would love it if I planted some kale.

Had the sealant repair in August (took 2 weeks) and leaked 3 days later. Took it back and took another 2 weeks for replacement window + sealant. Because so much water flows under the spoiler and dumps right on top of the window, I asked them how we could build the sealant up to where the water sheds off the top instead of sitting behind the window on the seal. They talked to GM and realized they were doing the repair incorrectly, and it looks like they did what I asked (although it looks a little messy). Also, I've been following this thread a long time and have seen many pictures of window frames posted. I have never seen a frame like the new one in my truck. They insisted this is THE new window design to address this issue. I have been told a few things that I know are untrue, so who knows but see below and take it for what it's worth.

After this mess, I have sold the truck to to a dealership for $500 less than what I paid in April with 5,000 miles on it (thankful I bought when they had 2x $6,500 discounts). I don't want this headache anymore. I keep my vehicles a long time and I refuse to worry about a leak every time it rains or I wash it.

Hopefully these pictures below help someone. I included the receipt from the work. If anyone knows anything about this window, please let me know. I am curious if it really is a new style window. (Keep in mind, I think the part number is the glass part numbers, not the window assembly part number). Good luck to everyone.

Hi, all

Newer AT4 owner here, and I read the past so-many pages of this thread, but 153 pages a long read.

So, please forgive the perhaps stupid question....

Is it possible to just replace this window with a solid non-sliding window that doesn't seem to have issues?

I don't have a leak yet, but I only have 1000 miles on my truck to-date.

I'm with everyone else - it won't fit in my garage and I will not sit and worry every time it rains if mine develops the issue.

Thx

Well I picked my truck up for the last and final repair to get things right. I got the most updated window (FUYAO E4 43R-000072) It water tested and everything was water tight so far. They still had shitty looking sealant around the window, but not as bad as the hack job they did before.

Is that THE window which does not leak? I sure as hell hope so. I just checked my 2020 AT4 built in July 2020 and that’s what it has.

My window is shown below. My Denali was built 8/19 and I took delivery a year ago this month. Window began leaking a month ago on drivers side. Took it in last week and the Dealer is waiting for bolts etc. to show up.
