Wind noise

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

Sorry, no solution. After the lifters failed and vehicle left me on the side of the road on vacation, I had the vehicle back to the dealer for engine issues they couldn't fix on 4 occasions.  I got a lawyer, settled with GM and dumped the vehicle.

SOURCE OF NOISE FOUND!!! 

 

After many failed attempts, and with hope of finding the source of the rattle on my own diminishing, I decided to get some help from my dad to drive my truck so I could sit in the passenger seat and hear the noise for myself. Armed with a stethoscope specifically made for cars (can be bought off of amazon for like $15 lol), I was sure I was going to find the noise. To knock out two birds with one stone, I went ahead and used some painters tape to seal up the windshield, where it meets with the body/door pillar. Much to my surprise, when we started driving down the road, I couldn't hear the noise. I thought I was losing my marbles lol. 

 

This led me to believe either the seal of the windshield itself was faulty, or the roof molding trim on top was creating the "rattle" noise. This made more sense to me as the sound increased with speed. Even though the molding had a bit of play, I initially threw it off the table because it really didn't seem that bad... That being said, I removed the small bit of tape that I rather unintentionally covered the end of the molding with. Low and behold, the noise returned! I found that the little plastic insert was rattling around and perhaps slapping against the roof of the truck. After taping off the area, I applied a small dap of black silicon under the end and taped it down for it to dry. On my drive to work this morning, the noise was GONE!!!

 

Needless to say, my marbles have been restored, and I know exactly what to look for when the driver side inevitably does the same thing lol. *Whew* All is well again lol.

Are you talking about the black plastic strip that runs the length of the roof?

The howling noise on the driver side door happened to me again today when I was traveling 75 mph in a strong crosswind. It does this anytime there is a strong headwind or crosswind at interstate speeds. I called my service advisor and he was able to hear it for himself so I have an appointment next week. On a cross-country trip last summer, I was able to eliminate the noise by rolling down the driver side window and applying a strip of painters tape over the gap in the door frame from the bottom forward edge of the window to the top rear corner of the door. This is on the door frame. I'm able to keep the window functional. A bit frustrating since you have to remove the tape any time you need to get out of the truck but it has allowed me to narrow the search a bit and eliminate the howling. The audio file posted here by Hunter103 on 10/14/21 is exactly the same noise I am getting. I have multiple videos of this. 

I'll report any findings ASAP.

Update: My dealer checked the front door gaps and they were within tolerance even though the driver side door gap was visibly larger than the passenger (noise was always coming from the driver side).  They replaced both front door weatherstrips (85530936 and 85530937) under warranty. I was able to drive yesterday at 75 mph in a 25-35 mph crosswind and was unable to duplicate the wind/howling noise. I'm considering this issue solved but will report here if it reoccurs.

I've been experiencing a wind noise when driving at highway speeds on both the driver and passenger side. I narrowed the problem down to the plastic caps on each mirror rattling due to the wind. I'm not sure how they got loose enough to rattle or whether there is a way to keep them from rattling. It may force me to replace the mirror caps with the body colored ones.

Seems like there are many different areas creating these noises with these vehicles... Mine was making the noise form the driver and passenger side windows and would stop when I rolled them down. Here is what the technician said at the dealership when I took the truck in to get it looked at. "Cause to be a fault with the weatherstripping being too soft". Ended up replacing the weatherstripping on both sides and have had no wind noise since.

My noise problem solved: 2014 Sierra, noise at 50+ MPH sounded like rapid loud tapping on windshield. Turned out it was the plastic windshield cowl where it butts up against the lower W/S. A thin application of black RTV under the lip cured the problem, took me a long time to isolate the source. These kinds of noises are deceiving, you might think they originate at one location but actually another.

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.

Just bought a used 2021 Chevy Silverado, 1500 LTZ 4 x 4, trail boss it Howells in the wind around the windshield, Howells with high crosswind. I’m certain the dealerships/ manufacturer are totally aware of this problem by now. I had some sketchy service from Winter Chevrolet in Pittsburgh California. I am looking to start a class action lawsuit under the lemon law. Please contact me at this email address if you would like to join me in this problem.

2020 Chevy Silverado, loud whistling/ vibrating high pitch when driving 70 - 85 mph, noise & Vibration appears to be coming from support "beam" between windshield & passenger side door/window.  Is there a recall or factory defect & what is the fix?

Matt, This sounds exactly the same as what was happening to my truck and the fix that I posted here on May 21, 2022.  This issue has been solved for me.

 

Update: My dealer checked the front door gaps and they were within tolerance even though the driver side door gap was visibly larger than the passenger (noise was always coming from the driver side).  They replaced both front door weatherstrips (85530936 and 85530937) under warranty. I was able to drive yesterday at 75 mph in a 25-35 mph crosswind and was unable to duplicate the wind/howling noise. I'm considering this issue solved but will report here if it reoccurs.

I have a 23 Silverado RST. Every drive at 50 mph and up, it sounds like there is a rear window open on the passenger side, had it in the dealer twice, and they say it's normal wind noise. My 14 Silverado was quiet as could be. I drove a 24 and it seemed worse. After 5000 miles I'm about done with this noisy truck

I have a 2020 Silverado with the same noise problem when driving 70/75 mph and a high crosswind. Seems to be coming around the side mirrors. If i pull the side  mirrors in, the howling stops. Side mirrors out, howling starts. Noise is not constant, but very irritating.

 

Mine was/ IS the chrome mirror backs, at just the right speed and wind it is wicked, only happened once when truck was very new and wind was really blowing.

I just bought a new 2024 RST.  I have excessive wind noise at 50mph and up, coming from the top of the driver side A pillar.  Is fairly constant but then is more gusty sounding when it’s breezy out.  In addition, the driver door doesn’t seem to stop much sound.  When I pass cars, it sounds like the window is cracked open or the door seals are not doing their job…. 
I’ve been to the dealership 4 or 5 times.  All they do is have different technicians drive the truck and they say that it’s all normal wind noise for this type of truck.

I love the truck, looks great, rides and drives great, but the wind noise is killing me!  I’m at my end… if anyone knows of a fix or can make a suggestion, I’m all ears!
