2024 sierra 1500 roof leak?

[nolimits]

Is this the roof leaf that they stopped production to fix? I checked multiple times and they say my truck is not under a recall but I appear to have some leaking on my passenger side rear roof.

 

I'm having it looked at tomorrow buy a dealer. What can I tell them to cut right down to the chase and not BS around?

Anything is possible, but it shouldn't be the roof tear.  Those trucks were all placed on a stop sale that were on lots to be fixed, and it was a very small window of trucks.  

 

Judging where your leak is, I'd be more inclined to think the rear window or the roof spoiler.

I appreciate the responses. It's a 2024 Sierra 1500 Denali that was purchased mid January and production was October or november, I'll have to check my sticker. It was definitely produced during the time frame. My 2023 that was previously totaled did not have this issue and I visited the car wash way more

If you have a new 2024 model truck, you should update your avatar to the correct info.

Where the headliner stops and meets the window. Look along that and see if the plastic window frame has a crack. Another thing it could be is the bolts that hold the spoiler on did not seal well when they were tightened. Here is the crack my 20 had when they took the window out for replacement.

They removed the headliner and have confirmed there is a leak. They are struggling to identify the source at the moment. It is very small and basically drips where I showed.

 

They said the usual suspects, back glass, rear roof spoiler do not seem to be the cause. I referred them to the GM Authority roof weld  cracking procedure/issue. They have to keep it until next week unfortunately.

 

GM social Media team says they will check on it next week. It's really frustrating such a new/expensive truck has an issue like this. They better fix it correctly.

Here's one of two fractures I found on the brittle plastic frame at the top edge of the rear glass. Repaired it back in December with a tube of 3M Urethane Seam Sealer, 08367, Black Color and it never leaked again. Just run a bead of this self leveling sealer alone the entire length of the plastic frame so water will never settle in the channel.

Is that photo taken from inside the cab or from the bed of the truck?

Taken from the outside looking down with the spoiler removed.

Here's a pic after applying the seam sealer. The sealer was glossy black. Blue painters tape was used to prevent any spillover onto the outside of the rear glass. Also, notice the circular rings of 3M windshield butyl tape I place around every bolt hole for the spoiler. I didn't trust the original foam washers that were deformed under compression when the spoiler was bolted from the factory.

If you are not aware already, this is a common problem that many have already posted about on this forum.
