At idle & various RPM ranges, affected blowers will emanate a "rattle"/vibration that goes away with a little more RPM or less as it develops a harmonic. I was told that failure of the bearing/isolator could cause fluid contamination leading to engine failure or the inability of the car to start. Ana gave me a "service request #" & a "supercharger warranty #" that amends the car's service/warranty profile for posterity. Not all 2012 - 2013 ZL1 CAMAROS are involved & a determination is made by VIN #. Naturally, my ZL1 #61 is involved, yet my car runs great... NO rattles, weird noises or other issues. She told me that details are being firmed up & procedures for addressing this problem will be finalized within 2 weeks & dealerships notified. Preliminary Service Bulletins are sketchy at best.

Have them give you a copy of the bulletin. Several errors in that Motor Authority article. I think they wrote it before reading the bulletin. Doesn't cause engine failure. The coupler is sealed from the engine oil. If the rattle is left to rattle, the front bearing of the supercharger can become contaminated and seize. If the supercharger is seized, the belt won't turn, and the engine won't start. The engines isn't damaged, just won't crank with the supercharger seized.
Nothing to finalize in 2 weeks, the dealer can see the bulletin now. It gives exactly what to check - supercharger rattle at idle, exactly what to replace - the new supercharger and gasket part numbers, and how long the new warranty is 10yrs/120,000 miles.
If it doesn't rattle, do nothing. If it rattles at idle, ask them to do the bulletin.
