My 2019 1.3i-vtec SE does it as well, but it does stop so I don't worry about it.
Thanks for replying. It's not that I'm worried myself but rather that if I was listening to some classical music with the engine off and there was a quiet/silent period in the music, then I would be able to hear 'the noise.' I would return a HiFi or toss it out of the window if it made this noise.
I think I now know what 'the noise' is:
After some searching I found this Fit thread:
https://www.fitfreak.net/forums/3rd-generation-2015/104388-stereo-has-cooling-fan.htmlSo if our units are the same ish, and I'm sure that they probably are, that looks very much like one of those little 40mm x 40mm fans you find in all sorts of things.
I'm staggered that someone thought it a good idea to put a fan in something that plays music. Maybe the logic was that the engine noise would mask it and a fan was a lot cheaper than producing less heat.
Now I'm stuck wondering if this is just a 'normal' sound or if my fan is dodgy. Can anyone else hear it?
