That's for a 3/4 and 1 ton trucks.

I have some wind noise coming from the upper RH side of my windshield. It sounds like a howling.

Noticed wind noise in my 2020 SLT yesterday, haven’t tried any tricks mentioned on here but man is it noticeable. My relative has the same truck except diesel, and his does it too.

It’s constant and doesn’t matter speed or whether AC is on/off. Has any one found a fix yet? Truck is fantastic regardless.

Anyone found a fix?

Yes. My 2021 trail boss has a very aggravating wind noise! It’s sounds to be around the driver and passenger windows, going in to dealership AGAIN tomorrow! Just another problem since the truck was new! Hope the solve issues, I’ll let you know.

I just got my back today. Mine was the mirrors. They replaced one of the end caps and it wasn’t mounted properly and it creates a howling sound. They snapped it back into place and it’s quiet again. Have them look at the mirrors.

Joined this to try and find a solution for this problem. Have a 2021 custom Silverado that has had this issue since I got it. I’ve recorded a video of the noise but I cannot upload it here

[2019 silverado ld]

I just bought a2019 silverado ld Ltd 32kmiles.  I'm hearing the wind noise from the windsheild like the defrost is on medium low but the system is totally off.  It must be an aerodynamics problem going back to the early 2000s because I had a 2004 sub lt and made me feel dizzy and ears ring.  Now the 2019 makes me dizzy and I can hear the windsheild noise now.  I'm going to remove the bug sheild tomorrow to see if it affects the sound.   I put in ear plugs and then drove, turned off the navigation system and turned off the climate control.  When I took out my ear plugs I could hear it from the windsheild and I could tell it got louder when the wind blew on the truck.  It also has a booming sound when hitting rough roads that makes me feel like I'm inside a bass box with some 90s rap on, boom boom boom boom.  My suburban did the same thing too I called it the thunder dome.  Cheap flimsy steal vibrating in the wind and shity suspension making the cab sound like a drum beating....  never a gm again.... never....

[2019 silverado ld]

I talked to a gm person on live chat about this vehicle making me feel dizzy, ringing in my ears, and hard to focus on the road while driving it. I think it's a combination of the constant wind noise in the windsheild area, vibrations on the cab itself from turbulent air and the booming bass noise in the cab from hitting expansion joints and bumps at 10 to 50 mph or so. Gm asked if I have gotten medical attention from it and told me to take it into a dealership and see I they can find out why it's doing it.   Pretty sure I'm not the only one experiencing this and it's being swept under the table.  2004 suburban did it and now this 2019 silverado 32k miles.   I think it might actually be doing damage to my hearing.  No issues like this at all with my f150, s10, explorer, lumina, corsica, Pacifica, but they seem smaller in the front, and no noises that remind me of bass associated with bumps on the road.  This silverado feels like driving an 80s Cadillac in the front. And a hard tail Harley in the back end.  The boxy shape and not enough air getting under and around that giant piece of plywood they call the front end of these turds is probably smashing into the windsheild and making turbulent air bang on the windsheild and doors because I can hear it there too.  It will probably cost me $10000 to get out of this pile now.  Gm should be buying this ****** back since it came from a chevrolet dealership.  Instead task a poor service tech to diagnose a problem that a team of scientists might be able to correct.  I said "I'll buy the loan out and crush it." Throw money and time at it and become a human experiment for a poor service tech wtf no no no.. I checked the screws by the mud flaps and around the wheel wells nothing seems out of place or loose.  It's just too bad because it's a very good looking truck but a nightmare to drive.  $42k dollar nightmare after taxes interest and fees.  Gm should be Ashamed of their engineering department and I'd flush that toilet if I was ceo.
