Why does my Honda Accord make a drone noise?

It occurs on longer trips, especially when going downhill. In my case, it only tends to occur when the green lights are re-charging the battery, and simply shifting down to D3 or pushing on the accelerator will eliminate it temporarily. How annoying! It started doing it at around 5K miles.

Is there a problem with my Honda Accord Hybrid?

My new Accord Hybrid also has the drone problem. At 55 Mph with four passengers the car goes into a very loud harmonic drone. I took it to the dealer today and they were unable to diagnose the problem.

How does ANC work on Honda Accord Hybrid?

The ANC system just addresses the exhaust resonance generated by switching to 3 cylinders since the exhaust is tuned for 6 cylinder operation. It has a very defined frequency band pass that generates the noise cancelling output from the speakers.

What to do about low rumbling harmonic in Honda Accord?

The vendor called a “senior tech at corporate” to talke about the ANC problem. It is specifically to address the low rumbling harmonic and they are working with the ANC vendor and do not yet have a solution. Anyone who has had their speakers replaced have not had the problem fixed permanently.

How does noise cancelling work on a Honda Accord?

I figure that noise cancelling headphones have a good history, so Honda likely uses the best tech to do this. The cancelling uses the radio amp to run the speakers so it very well might still allow those frequencies through that are in normal output from the radio/stereo signals.
