Got a new to me daily driver, 2011 CTS-V about 4 weeks ago and noticed the SC has a rattle at idle and when you shut it down. GM had realized they had a problem with these LSA Eaton SC's so they extended the warranty to 10 years or 120K miles. This one was replaced in Nov 2012 when it had 29k miles on it but they replaced it with the same PN that had the failures as the SB for the new units didn't release until May 2014 . Basically there were bearing failures that were caused by the faulty spring loaded isolator that were installed on 2009-2013 CTS-V's and 2012-2013 Camaro ZL1. In place of having dealers technicians repair the SC they elected just to replace it with the new style solid isolator units. In any event I have an appointment for Friday morning at my local dealer to see if I can get it replace under warranty as it was put into service in Oct of 2010 and has 92K miles on it. Wish me luck!
