There have been a few threads about cabin noise that have been difficult to isolate. I recalled a potential source for this noise during a previous road trip... the gasket on the window frames when the windows are closed during rough roads or higher speeds. It may be a faint rattle or chirping sound, difficult to localize. If you press firmly outward on the glass, it may stop. This has been a problem with other Honda models and I likely exasperate the problem because I cleaned the top rim of the windows.

The solution is to lubricate the window gasket with a silicone grease, as needed. I've used Honda Shin-Etsu grease which is expensive, but you will use a very small amount and a tube will last you a long time. Alternative is to try DANCO Waterproof Silicone Faucet Grease which is much cheaper and in a smaller tube. Non-silicone grease will cause rubber to swell.

Since lubricating the window gaskets, I've not noticed this particular cabin noise.

Thats no surprise, the same gaskets are used for both windows

Good advise, I'll try it, I certainly don't want any added wind noise distracting from my stereo upgrade...!

Just ordered it from Amazon, $4.34 delivered...!

Can you send us a pic as to where exactly you are applying the silicone grease. Thanks.

For each of the 4 doors, area to lubricate is the gasket that meets the top inside edge of the glass. Roll the windows down and apply grease to the gasket with your finger and remove excess with your finger... just need a very thin film of grease. Photo shown is for the front driver's side.

Resolution? Ear plugs. 😉

No, I prefer to hear the roar of the engine (the joys of a NA V6 or NA V8) and my surroundings. No music either on long road trip and my co-pilot is good with that. Because unlike most people, she enjoys and is able to read in a vehicle.

My post was pure facetiousness. In California, it's ILLEGAL to wear environment sound blocking apparatus while driving (or bicycling). As it should be anywhere in the USA.

The cabins in both of my 2021's are super quiet. No rattles, squeaks, chirps or wind noise. They are as quiet as both the Mercedes and BMW I parted with. I didn't think I'd get a quiet cabin with a Honda.

I'm intrigued by the use of the Honda Shin-Etsu grease. I purchased a PP Touring in fall of 2019 and by winter with only 1,500 miles start noticing loud road noise on the front passenger side. Now with only 6,100 miles, no one has been able to diagnose the problem which includes the dealership and a very reputable auto body shop (all body components are properly aligned and interior panels were removed for inspection too). I'm assuming by your post the product further enables the window to penetrate the window gasket for a seal? The door gaskets on the PP seem marginal in size and wondering if there is a product that might "swell" the rubber for a better fit? Thanks for sharing your knowledge, and, btw, there is no way your wife could read a book while in my passenger seat because of the noise. Also, if any one has experienced road noise at any of the doors and was able to have it remedied, I'd like to hear about the solution.

The window noise is relatively faint and noticeable if you are OCD. The benefits of silicone grease, like Shin-Etsu, is that it does not cause rubber to swell (swelling is terrible for o-rings). The gasket and window rubs against each other, causing a faint rattle or chirping (like a sneaker on a clean hardwood floor). Silicone grease will allow the gasket and window to move freely against each other over rough roads or at high speeds. Not an ideal fix, but a solution.

We have an Elite that has insulated glass for slightly lower cabin noise. While driving one time, I heard a "hissssss". Looked at my wife and she starts laughing at me. It was her! It is for the best that my wife keeps her head down reading and in her own world while I'm driving, though she periodically gets startled looking up at the wrong time.

If you think it is wind noise, try a few things. First, reset the auto up limit (just the last portion of this video at 2:20?). Second, try the silicone grease. Third, check the gasket around the front windshield.

Otherwise, check the tire for pebbles and debris that may be embedded between the treads? Reverse rotation of the tires if the tread blocks have uneven wear?

Good luck.

Greatly appreciate your reply. I'll purchase the Shin-Etsu and use as preventive maintenance, meanwhile my windows properly function and tight in the channel/seal. The gasket around the windshield has already been checked by the dealership and then at a auto body shop to be okay. One thing that I have noticed on the front passenger door is that the door gasket is held by push-in clips and the length of rubber between the clips is not adhered to the metal door frame. The tech at the auto body shop claims that Honda uses a "floating" gasket held by the clips and compresses to the body and door when it is shut and is held in position by the clips. However, on the other three doors, the rubber seems tight to the door between the anchor clips and I don't want to pull on them. Question for you: Are the door gaskets on your Elite adhered to the metal of the door or can be gently and slightly moved by hand? btw, my Touring glass,etc is the same as your Elite in reference to being insulated. I live alone, but when I do have a passenger the first thing they will do is make sure the door is closed and window up and then comment about the road noise.

Which door gasket are you referencing and particular area (photos)? My gaskets are snug, but I did not pull very hard. Yes, I believe the comment on how the gaskets are held in place, as that is my experience with gaskets on previous Hondas.

I presume that the door panels line up, so you don't want to be adjusting the door strikes? Another test to try... take a strip of index card and run it between the gaskets of the door and body frame? Check for any gaps that may exist. The more definitive check may be with a smoke test, if that works?
