    Is this sound normal?

    Happens at low speed when accelerating. Is this the turbo or cvt sound? Car runs normal.

    Which sound? The light, higher-pitcher ‘whirr’ that only happens for a second or two? It sounds like turbo whine, but I don’t hear it in my car.

    Yes, that's the sound! I never had a turbo or a cvt car so I don't know what's normal.

    I'm just trying to figure out if it's from the turbo or the cvt and if that noise is a problem or not.

    I took another video this morning with less cars around so it should be easier to hear.

    If anything, it was harder! Think I only heard it but once, WAY quiet in the background...

    does it sound like 4:45 in this video?

    A quieter version sound is present when I'm going faster, like 35+. If I'm going slower it's a lower pitch whistle. I had the car 1 year and I just heard this new sound so it's kind of bothering me.

    well, I can't really hear much in your videos, I was pretty sure it was your turbo, but after your last comment, perhaps not.

    I put the car in park/neutral and gave it a little gas to hear the turbo spin a little bit and it makes a different sound than what I'm hearing. Maybe it's the CVT.

    That's a good test. This is my first car with a CVT, I couldn't tell you what to expect as far as what's normal. How many miles do you have? I did read on here that these cars get transmission fluid "changes" more frequently than my previous hondas.

    If it sounds like belt whining, kinda like a supercharger it's the CVT. if its a turbine sound its the turbo.

    Would the CVT sound change pitch depending on how fast you're going? The sound I'm hearing is lower pitched and then it gets higher the faster you're going.

    Absolutely. Its a belt whine sound, not a turbo charge / airy sound.

    why would I only start hearing it now, do these things sound different as they're broken in?
