A few months back I was driving around with the windows down and notice a very distinct, soft yet noticeable whistle sound coming from my 2015 CRV AWD. The noise was easily replicated by driving to about 40 to 50km/h then taking my foot off the gas as letting the CRV coast and slowly lose speed. as the car slowed down the whistle noise would start changing in pitch as the car came to a stop. My CRV literally sounds like it has a turbo mounted underneath my ride. So I took to the net and saw that I am not alone. Many Accord drivers with the earth dreams engine/CVT combo report the same noise. But obviously not everyone is reporting this.
I took my CRV to the shop yesterday and the senior mechanic was easily able to hear the noise and was genuinely confused. He mentioned he had never really noticed the noise. He performed various checks, ensured fluids were topped up then compared my CRV to a used 2015 CRV on the used lot which he mentioned sounded similar as mine. Thus the dreaded "performing as designed" diagnosis and I was on my way. At least I have a work order from the dealer in case this "performing as designed" turns out to be incorrect in the future.
I am curious as to how many members may be experiencing this noise? Has anyone who had this noise ended up having CVT issues? The reason I ask is that this noise is common, from reading various Nissan sites, in CVT's that are failing or have CVT fluid issues (replacing the CVT fluid fixed the issue for some). Obviously the two CVT are different but it is concerning.
I also on the Nissan sites that this noise is also common with CVT's in general. I am no mechanic by any means and if this is true or not is beyond my knowledge. Any Honda techs on the site care to comment on CVT noise and the reliability of our Honda CVT transmissions? It would appear that Nissan has had a rough go of it with their version.
Thank you as always fellow members!
