Already got the new upgraded SC. Under light acceleration in first gear there is a brief but obvious rattle. I consider this a real turn off. Now I have to be more aggressive on the throttle for it not to rattle. Do the new 2014 and 2015 manuals have this rattling with its facory installed upgraded SC?? Any mods to reduce this rattle other than getting a louder exhaust?? For this momentary rattle to be mentioned in the TSB doesn't make it right or "OK". Customers should not accept this after paying close to 60 000$ This is an engineering screw up by GM and Eaton. If I were to test drive a 2015 zl1 and have noticed this vibration or rattle related to the solid isolator, it would have been enough for me not to purchase the car. Each customer is different but right now for me this is a real turn off and this may very welll be my last purchase from from a domestic car manufacturer. Going back to the dealer in hope that there is some adjustment to make this vibration/rattle less obvious. This will be my eighth visit to the garage ever since I purchased my 2013. (Transmission grinding noise, exhaust failure, front left wheel noise, back right suspension clunking, a damaged wheel by garage lift which the dealer denied, supercharger replacement, regular maintenance, and soon the key fab).
