Rear window leak

mattsvtcobra · December 10, 2019

Got the truck back. The glass looks great. There are some pry marks on one plastic part it seems. The back seat seems to be installed lower than it was before. I am not sure how that is even possible, does anyone know if there are adjustments?

f8l vnm, I'll check the build date of mine whenever they get it done again but mine is a 2020 2500hd. They said they had 1 other 2020 in as well for the same leak. Is there a way I can look it up using the vin? May be a few weeks again before I see it

Definatly going to video it next time so there no excuse. I've read several post on this thread where people can spray their garden hose directly on it with no leak but a decent soaking rain seems to bring it out.

I regret not taking a picture of it but I went to a car wash and put a stream of water on it, nothing leaked. Yet, it rained and a little puddle formed. I can see the drops coming in from the top of the right passenger side of the window. Black headliner and I don't see spots, don't foresee them replacing it anyway. Has to be a pretty strong rain for it to happen though.

Ok guys. Just received a call from the warranty manager. They have cleaned my headliner and according to them the stain came out completely. They also removed the rear seat and seat back and cleaned the padding and carpeting to ensure there so would be no mold/mildew issues. They also have extended my warranty to 60 months and 100,000 miles. They can’t make it leak from their water hose so we’ll see how it goes. There’s an 80% chance of rain on Friday and 50% on Saturday.

Picked up the truck and went straight to church for supper and a good ol property committee meeting. At 7:51 went back to truck. Opened rear door and noticed I can still see the water stain after it was cleaned along with a new stain. Took a ic and emailed it to Jarelyn my senior customer service person. I’m really frustrated right now. Just feel like I’m getting screwed at this point. What good is a warranty if they aren’t actually going to fix anything.

If there is a new leak it makes me think that it is coming in above the headliner somehow? Even though you can’t see it with a hose. The headliner is acting like a sponge.

No new leak. Same leak, same stain just not fixing it

Man, John, what a drama. So sorry. Thanks for sharing the updates with us.

Ok just got a text from my dealerships manager. He wanted to know if it was leaking again. I told him it wasn’t leaking after lunch today but I’d check and see. It’s been raining and misting since about 10 this morning. Took some pics this time. Water dripping down both sides. I sent him some pics and he said that’s all he needs for the next warranty claim and he’s going to have to go to GM to find out what to do next. I’m guessing a new window. They also looked at the truck yesterday and couldn’t believe they let it out with the headliner stained and have agreed to replace it. The headliner is back ordered but that’s not their fault.

To replace your headliner the windshield must be removed. GM's fix for the rear window is silicone first, 2nd attempt is a different sealer, 3rd is supposed to be a new window. I've been waiting for my back ordered new window for 2 months now.

This will be the third rear window fix. The windshield will most likely be broken during removal and have to be replaced but they can’t order a new one until the one breaks during removal.

They removed my windshield to replace my headliner and as far as I know, they didn’t break the windshield. He’s hoping for a good outcome!

2 months!?

My dealer here in so cal ordered mine about 10 days ago. It was back ordered but I got a call a week later saying it was in. Scheduled the install for this morning but then they cancelled because they said they never got confirmation from their outsourced installer. Now it's looking like it might be going in later this week. We'll see!

Ugh, I just called my dealer with the info you provided and they tell me "The people on the forums are wrong", can yu do me a favor when your truck is done, PM me your work order reciept once your truck is done so I can show my dealer, the dealers love telling customers the forums are wrong just to cover their butts. If you would I'd appreciate it, if not I understand.
