My 21 Silverado 1500 sounds like a someone blowing over an empty pop bottle at 70+ with a strong crosswind.  Upper passenger side windshield is where it appears to be coming from.  
 

 I thought maybe it was my new windshield.  This post has me thinking otherwise.  Anybody have a fix yet?

I have the same howling noise as well.  Only happens on strong windy days and I swear, I can literally feel the truck move a little likes it’s taking in wind when it happens.  Been waiting for a call back from my dealer for 3 weeks now with new door to Body seals.

I have a 2020 silverado, trailboss, and I have the same issue.  When driving into a crosswind, door or window whistles.  If it is a real windy day, it whistles so loud that I can barely hear the radio.  It is worse on the passenger side, but driver side will do it as well.  Dealership tried adjusting the passenger door twice, and it hasn't helped any.  

 

Does anyone have any updates/fixes to this issue?

I had maybe the same issue.  I took a video of it and sent it to the service guys. It sounded like a clarinet playing a single, really bad note.  Loud enough that it was hard to talk over.  Started with a strong head wind on the highway.  The lowest speed that it would make the noise was abt 65, but more often than not closer to 80.  One of the techs said that he know someone that had seen it before.  They found it.  It was the passenger side weather-strip that cause it.  They ordered new and replaced it.  We had 30 mph north wind they day they replaced it.  The tech could not reproduce the issue after replacing the weather-stripping.

I hadn't heard it again after that one time. Still hadn't brought it to the dealership.  Truck is 4 months old and only 2300 miles including a 1000 mile trip to buy it. I will update once I have the energy to bring it in.

was it the weather strip around the door or window?

I just got back from a 500 mile trip out of town and experienced the same howling on the driver's side of my 2021 AT4.  Anyone know which weather stripping the dealers are changing out to alleviate this?

 

Thanks

Been having this same loud whistling issue at highway speeds with my 2021 6.2 liter AT4. However I seem to notice that when I hear this whistle as soon as I crack my window the whistling stops. Any ideas?

Similar problem (2020 1500 RST), passenger side approximately below air vent in dash or adjacent spot on door.  Starts at about 45 mph.  Mine is more like a rattle/vibration that increases with speed.  Some crosswinds will nearly make it go away for a bit.

Thanks for the update. Was it a rattle noise or a loud howling? I have an AT4 6.2 with 1500 miles on it and for the first time over the weekend heard this very loud howling noise that came and went when I was driving about 75 mph in strong crosswind.  So loud my wife and I went WTF. 

I have a very loud howling on mine as well, but sounds like its coming near my left ear.  Was your sounds that high up on the door frame?  Mine is at 70 plus and cross winds as well. Just want to get this fixed asap. Any additional help is greatly appreciated.

Same issue here. Did you ever find a solution? It’s driving me nuts!

    • Thanks for the point of reference 
    • Great question. Answer....depends. One the volume of the crankcase, the driver that will actually be using the vehicle and the amount it uses plus the distance expected for that next trip. Couple of for instances:   Wife is going to drive Dizzy to Moline and back plus a bit around town so say 500 miles on the day. I know from years with that SUV that around town and local rural it uses about a quart in 1250 miles. But on the Interstate and her at the wheel without her anchor nagging her she'll push it and it will drop a quart in about 800 miles. Hence, around town I wait to somewhere between a quarter down to a quart down. On her trip I'd top it if it was down a few ounces and hope for the best.    Have I overfilled one? You mean by adding before it needs a full quart I assume. No, not once after finding the true fill mark.  I know the dipsticks of everything I drive and add what it needs. I learn this by doing the first oil change a quart low. Run the motor for a few minutes. Let it sit over night. Check and mark. Then add half a cup at a time making note of the place on the stick. I add through the dipstick tube with a barbeque basting bottle. Give it a few minutes to drain down and check again.    A vehicle like Dizzy that uses this much oil will take a few quarts between 3K changes. I keep one in the vehicle with the bottle and a bag. (Mindful of it's fullness) Not a big deal and never makes a mess of it. There is no such thing as "multiple quarts' in my shop for any specific oil. There will be a maximum however of the number of different oils used over the fleet.     Dizzy holds a nominal 5 quarts. So the first fill was indeed over as it actually took 4.75. My vehicles are fit with Valvomax valves so I can meter an ounce on the drain if need be. Found her mark first crack at it. Never to be repeated.    Pepper uses none between changes so I don't keep a quart in that one. Straight up 6 quarts put her dead on the full line. Check it ever fuel stop. They will surprise you when they start using.    Raven holds 3 liters or 5.44 ounces over three quarts. I add 3 quarts and 6 ounces. That gives me 5 oil changes on my orphan quart.    Lawnmower holds about 3/5 of a quart. I don't over fill it to prevent an orphan. So yea, depends. 
    • 185k on original 6.2L engine and 10 speed. 6" lift with 35" tires. Changed oil (Mobil 1 synthetic) when truck told me to. Original tranny with original fluid and no service or flush done. All highway miles. A/C compressor replaced at 155k. Oil cooler line replaced at 180k. Still daily driver. Love this truck.   This is my 3rd 6.2L vehicle (2008 Yukon Denali / 2018 Cadillac Escalade) with over 150k miles and no issues. Denali had broken motor mount at 100k.
