    Does you V vibrate or make a noise while doing a stall test?

    so after the supercharger replacements the sound is still there and GM is saying drive the car for 500 miles and the sound should go away and i told them BS. the dealership said they have new cars on the lot making the same noise can you guys do this test for me please

    put the car in park
    hold the brake down with one foot
    put thecae in gear
    give it a little gas 900-1200 rpm
    listen or feel for vibration at a certain point
    in my case you can hear and feel the vibration through out the car

    these steps are how i duplicate the problem while putting the engine under a little bit of load i normally don't do this normally i feel this when i am on an incline or something

    Isnt this the isolate bearing inside the charger? If it is, mine has it, my friends has it and most other V2s have it. Im totally fighting the dealership to replace it but they are keep saying its normal. However, i wont give up on this one.

    My dealership has put in 4 new super chargers and all of them had this issue. They told me that they have a new car in the Lot that did not have this and they are replacing its super charger with mine (sounds way too fishy to me as no dealership in their right mind will let the service department open up a brand new cadillac to fix an old one) they also put in a new complete exhaust.

    Hello uptownvinc,

    I apologize that you are experiencing this concern as well with your vehicle and disagree with what the dealership is telling you. I cannot guarantee a different resolution, but I would be more than happy to reach out to the dealership and speak with them further about this concern. Please private message if this is something that you would like me to do.

    Well my car is finally fixed yaaaaaaaaa

    They are saying that they had 5 Vs in the dealership and 3 made the sound and 2 didn't and once they swapped the super charger now my car is not making it any more and the new one is. Also they are saying it is a casting issue with the super charger that is why the 4 new super chargers they put on were making the noise. In any case i get the car back tomorrow i am so excited.
