2021 RST Crew Cab Wind Noise at Door Seals

Recommended Posts

I know that I can't be the only one that has a leaking door seal allowing wind noise in my 2021 Silverado RST 3.0 Duramax Crew Cab 4WD. I tried searching this forum but didn't find anything. I searched the internet and don't see my issue either.


I have had both front door gaskets replaced twice and it still hasn't fixed the wind noise in the cab. I know they're leaking because I have driven down a dusty road and you can see where the dust entered between the seals.


I have had two different dealers change out the seals. I know that I'm not the only one because my dealer told me that they have worked on others and some are fixed afterward and some are worse. I just had them changed today for the second time and it's as bad as it was or worse. It's hard to tell because it's very windy outside today. The rear doors don't seem to leak.


When the wind is calm outside, I can't hear it leaking but if I drive in a crosswind then it really leaks bad.


I don't know what to do from here but I'm still not satisfied. I hate it too because this little pickup is everything I want; great ride, looks good, all the comfort that I want, fantastic fuel mileage, and shifts great with the 10 speed.


Makes me want to pull a Thelma and Louise at the closest cliff.

I have this issue on my 17. The problem with mine is the frame of the door around the window is inset of the front pillar. I believe there was a tsb... In this tsb, the fix was to put something between the door and the cab (window rolled down) and flex it to the appropriate shape 😬 At the time I decided I didn't trust anyone enough to do this, and now I can't hear it over the exhaust so it doesn't matter. 


Anyways, I'd recommend checking out the alignment. Seals wont matter if the door isn't where its supposed to be.

I have the same issue with my truck and I'm extremely mad about this. Sounds like a train whistle right beside my ear.
