Hi, I too have a whistle coming from the engine, I notice it when I am going very slow, not so much when going faster with the radio or ac running but definitely hear a whistle type noise coming from the engine, only when in gear, not while in park. I haven’t tried it in sport mode but will check when I drive it again. i did point the noise out to the service advisor and they said they didn’t hear anything but would have the tech look for it when they changed the oil, this was at about 3,000 miles. I had described the noise to the advisor as something that reminded me of a noise in older cars that had power steering pumps and the pump would be low on fluid, that is what the sound reminded me of. I have a 2020 Kicks SR. When I picked the car up from the oil change being completed the advisor immediately said to me we checked and there is nothing wrong with the transmission………now I’m suspect as I never told the advisor that I thought it was the transmission but rather I’m hearing a noise that doesn’t sound normal to me. So why would he lead immediately with nothing wrong with the transmission? That is anyones guess but at least they noted it on the paperwork that there is nothing wrong with the transmission. Overall a weird experience I would say though, I’m not completely comfortable with the car now regarding longevity of the CVT- with all the bad press on this I may be just trading it in and getting something without a CVT. May be nothing as well. Hope this helps.
