I just bought a Honda Accord 2018 Sport 2.0. The car (absolutely stock) feels like my previous two Accords, but has a problem: the Active Noise Cancelling (ANC) system makes a loud droning noise. The noise seems to happen when the inside of the car is less than approximately 45 degrees and the car is in motion and neither the driver’s window nor the front passenger’s window is open (even open a crack will do).
The Dealer has called the Factory and was told that Honda’s engineers are working on it, but have no solution thus far, and that the Dealer may not disconnect the ANC device (which lives behind the glove box). I contacted Honda, who told me that they had no information on the issue.
So I have to live with the droning noise.
Have you heard of this issue? (There are numerous articles about it on the Web, but I have never read nor heard anything about it in any reviews.)
Any idea what models are affected by it and how prevalent the issue might be?
Any guess as to why Honda is telling the Dealer not to disconnect the device?
I would greatly appreciate any information you can give me.
