Powerboost whistle?

[Invinceable86]

Yup, 3600 miles on mine and yes u can hear the hybrid system wine when engaged. More audible when ur windows are up. I just lower the windows this time of year and listen to the turbos instead ?

I gotcha lol, so you didn't notice the whine noise in the summer time? I bought mine in July with 17k miles and didn't notice the noise until winter. I have windows down most of the time and cooling seats active which could of covered up the noise. I also have the hybird speaker bypass module.

I still can't believe there hasn't been a fix for this or least what is causing the whine noise.

Still have it with mine. Never went away. 55K miles. At this point, I guess I am just used to it. Pretty frustrating though that they never came up with a solution for it.

Thanks for letting me know your experience. I’m definitely curious if it will go away during hot Florida summer. I did not notice it until winter time. Maybe having windows down, cooling seats on and hybrid speaker active covered up the noise.

If u ignore it just right it sounds like a supercharger whine ?
