What is the noise and what does the TSB to fix it say to do to fix it? I knocks on wood also haven't had any weird noises from either of my 10th gen accords or my 10th gen civic. Despite the fact that a bunch of people apparently get all kinds of rattles and stuff...

The active noise cancellation (ANC) in the 10th gen Accord Hybrid would, apparently, react to some vibration when the hybrid's clutch was engaged in the 50-55 mph range. It would send out a noise that was trying negate a sound that wasn't there, creating a droning sound that was there.

It can't affect any other car, and the fix was a new ANC unit.
