2018 Honda Accord EX-L Hybrid Howling

5534 Views 17 Replies 8 Participants Last post by  Pam B.
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.

I forgot to mention that I asked the dealership to disconnect the active noise control. They reported that it made no difference...
I 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 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 had the same issue with my 2018 Honda Accord Hybrid Touring. The issue has been resolved now- after months of this issue.

Noise Cancellation system issue. The dealer needed to be essentially led by hand to find a fix.
They reflashed my Vehicles center/audio software.
I also had the rubber seal for the driver side door (the thin strip that connects close to the rear door).
Overtime getting in and out of the car, with the seat sitting so low, We are not noticing that our arms we are not noticing that our shoulders or forearms are rubbing against that material which can wear it.

I asked the dealer to install another rubber strip and reinstalled my software and the issue was finally resolved. Just resetting the software through the touch screen will not fix it.

The android-based software the vehicle uses, I think is the problem.

Sometimes the system will act wonky, and essentially will force you to do a reset. But after the dealership reinstalled my software the drowning noise went away.

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?
Sorry I have not been back on here to follow up sooner. At one point, the Service Tech did disconnect the blue tooth. Then I drove for a couple of weeks with no noise. Then they ordered a new blue tooth and installed it. When I got the car back, not only was it still making the noise at 54 mph but also at 35 mph. The car went back into the shop (one of many times) for the last time on Jan. 24. They kept the car until Feb 24. They took it apart many times trying many, many fixes. Finally a Rep from Honda America went out to take a look. It only makes the noise when running off the gas engine and not the EV. They tried a couple more things and returned the car to me still making noise at 54 mph but not at 35 mph. During this time I contacted Honda America requesting they take the car back. At that time it had only about 1,900 miles on it and had been in the shop seemingly more than in my possession. After several calls back and forth I was told that Honda America was declining to buy the car back and they are now stating this is a "known characteristic" of the car. My position is, if it was a "known characteristic" it should be disclosed to potential buyers prior to purchase. And, if it is known, why did they not let my local Honda Dealer service shop know from the beginning? My shop was in contact with Honda America almost from the start and most of the fixes they tried were at the direction of Honda America. Then Honda America offered me a $350 gift card to use at the local Honda for service or accessories. WTH! They seem to have used my car as a Guinea pig. So now I have filed a complaint with the National Center for Dispute Resolution as outlined in the materials that came with the car when I purchased it. The NCDR apparently has 40 days to make a decision in my case. I will let you know how it turns out.

I have the same problem with my 2020 HAH touring. Pam B how did your complaint with NCDR go.
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.

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. :unsure:
I’ve replaced the ANC and the noise is still there. They told me their waiting for response from a Honda support. Do I file a compliant now, or do I have to go though the whole repair process with Honda? By the way, thank you. Do you have a case number?
My car was in the shop repeatedly. Once they kept it for a whole month and over and over again tried repairs at the direction of Honda America. A technician from Honda America even went to Elk Grove Honda to try to advise them. I felt like my car was just a test Guinea pig. What did they have to lose after all? I think this is my case number #9VDKZTW4X. The person at NCDS who helped me was Rosemary M. Bass. Good luck!

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.

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.
There are 3 discussion sites on this forum about the same issue. No one except Pam has posted a real just resolution. NCDS will not use another claim to support mine. How many with the same issue have filed with NCDS?
When so many have the same issue, Honda should acknowledge it, address it and resolve it, and not put us on the same merry-go-round. Thanks again, Pam. You’re my hero.

Honda apparently has this issue on the 2018, 2019, and 2020 hybrids. It is a known problem. During my discussion with a representative from American Honda, she told me they were working on a solution. I told her that since they have not found a solution through three model years it did not seem likely one was coming anytime soon. Honda America was not helpful to me. I repeatedly asked to speak to the Area or District Manager but never got a response. After getting the run around I told them I would be unlikely to ever buy another Honda and I had been a Honda Accord owner for about 20 years. They did not care. So now I drive a Toyota Camry XLE Hybrid. And I am sorry to say I can no longer recommend Honda based on this customer service experience. Good luck Jay. It takes months to resolve. Keep all of the records for the numerous repair attempts as you will need to submit copies of them with your written complaint to NCDS. Please keep us posted and let us know what happens.
