2014 Zl1 supercharger Noise

I have a 2014 ZL1 and can hear supercharger noise at idle, it sounds like marbles rolling around. I thought the 2014 models had the new isolator ? Could some of them still have the old style ?

CTSv forums say the earliest LSA in 2014 may have a spring loaded isolator instead of the updated solid isolator. So, I believe it is possilbe...what # car?

I wonder if there is any way to get the information from GM as to when they started using the solid coupler. Is that information available even to the dealerships?

I'm not sure I really have to worry, as mine was born 5/20 of this year, but, who knows?

it has been mentioned the LSA must be manufactured early 2014 to get the solid isolator. '14 cars manufactured in late '13 may have a spring loaded isolator.

If I hear nothing right now in my 2013 model with 4000 miles on it at idle can it eventually happen?
Are all cars effected by this?
