So in the process of replacing my headliner because of water staining from the rear window leak, I now have a leak from my front window... Apparently the front windshield had to be removed to replace the headliner. Oh, and my rear window is leaking AGAIN!!! My dealership has tried to reseal the original window, then the entire rear window was replaced, then the new rear window was resealed, and now I've discovered the leak yet again. I'll be calling back my Chevy corporate rep tomorrow, and possibly a SC lemon law lawyer depending on how the conversation with Chevy goes...

Why would they have to remove the windshield to replace the headliner? That's like trying to pull a tooth by reaching through your rectum. On a Silverado/Sierra or like on my old Avalanches it is done by removing the rear window, not the windshield as has to done with a sedan.

And evidently from the recurrent leak the rear window should have been removed for a proper repair and headliner installed through the rear access. And just a thought...a sunroof?.......if so may be a blocked drain tube in the "A" pillar which is where that leak would show up.........pop the threshold trim plate a windshield leak would show up as a soaked jute carpet backing and water in the wiring loom channel underneath.

Great info Thomcat.... When I brought mine in for the rear window they discovered the leak in the front. The carpet was wet under the mat. They figured out that when the truck was built, the sunroof drain line wasn't properly connected and it was draining on the floor similar to that picture. Worth a shot...

It’s just the way it is, the headliner doesn’t fold and the only way to get it out and a new one in is to remove the windshield.

I have a 2019 RST with the same issue. I will be bring it back in for the same issue for the 3rd time. First time they tried to bandaid it when I was told it was being replaced ( siliconing or butyl from the outside) . Second time I was assured that they would be actually be replacing the window. Third time all parties were irate. Dealership, body shop, window shop. Long process seeing as the headliner and cab spoiler need to be removed to access the window. Yesterday when I took it in for them to check for the third time and I brought it into the shop so they could hit it with the wand with the dealership and mechanic present so they could see and the mechanic said he thinks it's actually coming from the cab spoiler. Must not be sealed properly but it comes in at such a weird spot. Driver's side top right hand corner of the rear window. It comes in from behind the read window rail corner. Completely dry if you run your finger through the track but where it attaches to the window it makes a slow stream inside. Mechanic said I was lucky because one guy had it flood into the cab and destroyed his head liner. Let them know it could be the cab spoiler so you guys dont have the same headache IV had driving a loner for over a week total.

I posted just a little bit earlier, rear window might be the cab spoilers not sealed. In on my 3rd time in for a replacement

My rear window is getting replaced now, went in on 4/06, and still no word when it will be done. They are getting a glass specialist to install rear window, but the second they call me to tell me its done, its going to get traded in. Just don't want to deal with it anymore since people are still getting leaking windows even with a replacement. I drive too many miles and will be out of warranty very soon and don't want to be stuck paying out of pocket later down the road.

What will you trade it for?

davester · April 11, 2020

You really want to trade it in now? They know you want to dump it, do they'll lowball you, and there's a ever decreasing selection of vehicles to choose from to replace it...

He doesn't have to trade it in at that dealer.

And the uconnect infotainment... We had it in our 2014 Jeep Grand Cherokee and it was glitchy and would go completely black from time to time.

What about one with a solid rear window since it seems like there’s no issues

I've had tons of problems with the gm one in my sierra, goes black, changes volume, plays multiple sources at the same time and wont let me change anything. There are problems with uconnect for sure, but probably not any worse than the gm/chevy. Honestly I think its just luck if you get one from either company that actually works right.
