Hi all,

I just replaced my supercharger at GM dealer under the special warranty due to the well know rattle noise. However, a new noise developed now at idle, this noise was there since I received the car, it is exactly the sound in this video: http://youtu.be/rnoHdEJDD-8

The supervisor and the technician told me it is normal and pulled out the bulletin that talks about the supercharger noise 800-900 rpm under load. But the noise in my car is at idle.

please let me know if I should worry about it. Thanks.

Sounds normal to me! My 2014 V has the new style supercharger and sounds just like that. Dealer won't replace it.

I am on my 3rd one and noise is still there.

so I should not worry about it?

would the noise disappear if I replace the isolator with an aftermarket solid isolator?
