2009 CTS-V , 2011 CTS-V Coupe, 2012 CTS-V Sedan, 2016 CTS-V
I had my supercharger replaced under warranty on my 2012 sedan. I was skeptical concerning this work due to the results from fellow V owners. I'M very satisfied with the maintenance performed by the Whibbs Cadillac in Pensacola FL. My V is real quite compared to the marbles in a can I dropped off. Hope other V owners will have the same success if you require this service/warranty work performed.
