Can anyone else hear a faint high pitch noise when the ima is charging? It is hard to hear, but I hear it. Actually I hear it when there is assist as well. I can only hear it a low speed, less than 20 mph or so. It sounds like it is coming from the engine.

Yup. When you charge there is a high pitched whine. I personally can't hear it under assist but of course at that time the motor is running.

That's a normal noise for the IMA motor when it's in generator mode. Kind of sounds like "szing, szing, sszziing." I love hearing that noise! I'm making power :lol: Fantastic.

Hmmm, guess I've never heard it, though then again I guess I never turn my stereo down enough to hear it. I'll have to try it some time. I can hear all sorts of stuff it seems others can't so should be interesting. Though it makes you wounder just how much EMF might be traveling right underneath you.

I am so glad someone asked about this. I searched thought the posts and found nothing. My car was still doing everything as wonderfully as usual but I hear that high faint pitch noise and was a little worried....

I have only had my insight a few months and only started hearing it recently. I am still wondering if this is the same one you guys are talking about, because I didn't hear it before. :?

I seem to get a high pitched whine from what seems to come from the ICE on some colder mornings when traveling at highway speeds. Seems to disappear once it gets a chance to warm up though.

The Whine

I've noticed similar to Braxus. I call it the "electric sound", because it sounds like the electric-like motors they used as sound effects for the van during the start of the movie "Bicentennial Man". I haven't thought it's a big deal, and I'm the opposite of many here -- I usually have my stereo *off* when I'm driving. Of course, I compose music professionally, so most of the time when I'm driving I'm working out a theme in my head, so it's very difficult to do that while listening to someone else's work :)

After the car is warmed up, the sound is less pronounced, though still present.

Yes I can hear it in my Civic Hybrid. It really pays to have dog ears.
