I forgot to mention that I asked the dealership to disconnect the active noise control. They reported that it made no difference...
I bought a 2019 Honda Accord Hybrid five days ago and it has the exact issue you describe. The only difference is the howling noise usually occurs around 54 mph for me. I took it in to my local dealer today. They observed the noise, could not figure it out, contacted Honda America and were told it is a "known problem that is under investigation." One possible fix that has a 50 50 chance of working, is to replace one, two, or all three of the noise cancelling microphones. They ordered the parts today. The work involves removing the headliner, checking the insulation, and replacing the mic(s). I am very unhappy. I barely have 400 miles on this car. I am worried this repair will not work. I am also worried the car will develop a lot of rattles after they have the headliner out and in. I feel like this "known problem" should be disclosed to customers BEFORE they are sold the car.I purchased a new 2018 Honda Accord in late September 2018. I soon noticed an occasional "howling". I've hear it at speeds between 25 and 70. It is VERY distracting and makes it difficult to hold a conversation. It gets so loud you can;t hear the radio! The sound seems to come from the front windshield column tweeters. It starts out low and grows to a very high level in a few seconds and then immediately STOPS. It may not come back for 20 miles. The dealership has verified the noise and has indicated that Honda is aware of the problem and it is currently "under investigation". It has been months with no indication they are closer to a solution. This isn't the old mirror wind noise Honda once had. This sounds like a soft deep "woooo" that quickly ramps up to "OOOOO" and then stops. Holding a conversation in the vehicle is impossible. The vehicle has 2,100 miles on it and I hate the car now! BTW: The passenger thinks it is coming from their side, the driver thinks it is coming from their side.
my just got out of the dealer same problem they have not idea , replace the noice cancelation sensor but nothing got corrected, please file a complained on the NHTSA web page so honda can take us seriusI too have the save vehicle, picked up in September, that is making the same howling sound. Only when motor/generator is running. When it goes into EV, the sound stops like it was switched off. Low engine loads generally. Once it starts, I can amplify it by keeping the gas in a certain range.
Today at dealer for the first time, they called tonite and said something about it’s with the active noise cancellation. They turned it off, which also affects the hands free system they say. They said there is no fix for it yet.
I told him I refuse to pick up the car and I want a loaner. Tomorrow I go in to talk to the manager.
I had the same issue with my 2018 Honda Accord Hybrid Touring. The issue has been resolved now- after months of this issue.I purchased a new 2018 Honda Accord in late September 2018.

I'm seeing others with the same issue who state disconnecting their phones/Bluetooth/microphones will help. Have you tested that? Otherwise, could you or the dealership disable ANC and see if that helps?I purchased a new 2018 Honda Accord in late September 2018. I soon noticed an occasional "howling".

Glad to hear your issue was resolved to your satisfaction. Hopefully others w/this problem will follow your lead and contact NCDR... I would think it wouldn't take Honda long to figure an adequate fix if they have to buy back a lot of cars.Honda America offered me a $350 gift card which of course I turned down. I filed my complaint with the NCDR and provided all of the records regarding repair attempts. The three-member NCDR panel ruled unanimously in my favor. Honda America bought back the car from me in early May. Just before Memorial Day I purchased a 2020 Toyota Camry Hybrid XLE. No problems with my new car. I may never purchase another Honda product after all the difficulties they put me thru with this vehicle with a "known characteristic" that Honda fails to disclose to their customers prior to selling these cars.
That's not out of the ordinary to allow the manufacturer the opportunity to correct the issue. Just make sure you document and get repair orders for everything they try/do to correct the issue.... documentation will be your evidence.Thanks for the information but it looks like I have to go through the whole process and give Honda a chance to repair. Thanks for your response and concern.
