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.
