I think any other person hearing the sound would think that is how the car should sound. I don't even know how to describe it other than it is an ambient sound that becomes noticeable at certain times.
Since you posted at the end of September, has your CVT whine become louder?
I'm the original owner and very perceptive of changes to my vehicles be it feeling or sounds. The whine was most definitely not present when new...lest I wouldn't have bought the thing seeing how I was capitulating over the purchase because
of the unknown to me slush-box (CVT). Whine of the magnitude we're discussing here is NOT normal.
I noticed the whine beginning many, many years (and miles) ago and reported it to the dealer while still under powertrain warranty. Dealer could have cared less, since, Suzuki had zero recommendations for doing anything with/to the trans at that low mileage back then. No codes, no problems, right?
All any dealer cares about is how they're going to get paid. Suzuki wouldn't have warrantied anything on a functioning trans back then (or now for that matter), whine or not. Hence they don't pay the dealer to do the right thing. So that leaves me paying with no guarantees...not.
Fast forward to 75-80k miles a little over a year ago and the whine was so loud during the summer heat after a hard romp I could hear it over the stereo w/ the car buttoned up an the A/C on when taking off from a dead stop. If something wasn't done, it's goose was cooked and my beloved Kizashi would become another failed CVT statistic. So began the fluid swap adventure. I give credit to those preceding me who had done the research, detective work, and performed the service on their own.
Today, 11k+ miles after its first DIY servicing, the whine is now more perceivable again, however nothing like it had been before changing the fluid. And, it quiets down quite a bit in the cooler weather. The romps I put it through don't change much with weather btw. At this point, after not servicing it for far too long initially, it'll always whine to some degree and it's merely a matter of prolonging the inevitable for as long as possible. I'd planned on doing the 3 drain procedure again at 100k miles (20k after initial factory fill replacement). I've tucked the Kiz in to the garage this week for winter (for the most part) and it's sitting at a little over 91,500 miles. I may perform the service again earlier than my planned 100k, next spring/early summer, since a) the 3rd drain of the Kiz's fluid was still far nastier looking than the single drain out of the wife's 55k mile 2011 SX4, and b) it's whining louder than it was a year or so ago after the initial service. Old Tech has made references to internal parts that are likely failing that cause the whine, so as I say, hopefully clean(er) fluid prolongs the inevitable. I'll likely just do fluid and no filters this go-round.
I will say, as much as I love the Kizashi, if the trans dies (or any other unlikely major problem occurs), it will become history.
