    So it looks like finally GM is going with solid bushing that W4M has been recommending to us for years.

    Pretty much, yeah. They knew about this otherwise, why would they use a solid isolator? 2011 models and up should have been using the ZL1 supercharger. Instead, we get the shaft.

    Apparently so, but hopefully not, see above response.

    I'm willing to bet they already have hundreds upon hundreds of the V superchargers so it's easy for them to just give us the shaft and give the ZL1 guys the new and improved.

    Now I'm not trying to be critical but there are a crapload of us dealing with this. I second the post about asking the GM reps who pop in here from time to time with gracious responses about issues we have to understand that we are voicing to GM that this needs to be a retrofit into our cars. Or.....warranty the blower for life. I'll take either one.

    Re: GM found a fix for the supercharger rattle!

    I still don't know why such a big deal is made about the isolator. Yes, if its rattling to loud, it's embarrassing. But it also seems like the rattle lessens as miles pile up. Also, how can it damage the blower? It's a contained are, correct?

    Enlighten me please.

    Well, you're incorrect in that the rattle lessens up as miles pile up. That's not accurate. it gets worse. In my case at least, it got worse up until the supercharger was replaced at 33k miles. it can't damage the blower, and it is in a contained "are".

    +1! It only gets worse. Mine is getting even louder and my supercharger is pretty new. It's actually rattling above 1200 rpm, so much for GM following their own TSB. Around 2000rpm-2200rpm, the rattle is very quick and loud. Then once you pass 2500 rpm, the supercharger whine/exhaust/engine drown it out.

    Yep. Eventually the stock isolator will get worse and worse until it takes out your blower. It's cheaper for GM to fix the few blowers that go out before 100k than to do a recall on every single one that makes noise. Im glad I didnt listen to the GM b.s. about it be "normal" and had it replaced with a solid isolator when I did.

    Re: GM found a fix for the supercharger rattle!

    Pretty new to the CTS-V sceen so sorry for any noob questions. Does GM replace the existing isolater if you have the supercharger rattle? Also, if going with a solid isolater fixes the issue, how much does parts and labor run? Obviously GM would not do this, but how much would a local LSx shop charge for somthing like this?

    The supercharger comes from Eaton. GM therefore feels the supercharger is a non-serviceable part. Further, they feel that the sound is normal. Therefore, they are only occasionally replacing superchargers.

    The replacement solid isolator is an inexpensive part. Installing it voids the drivetrain warranty even though it solves the problem, so install at your own risk. Others can comment on the install cost but I don't recall it being very high.

    w4m was right all along.
    LV_V and LV_V like this.

    He's not incorrect because in my case, the rattle noise has decreased significantly at 20K miles. Obviously, not the case for all, but in my case yes.

    A fix, or was this a Cadillac specific item? Anyone know if the ZR1 has the same rattle? Also, it is interesting that the ZL1 was put on quality hold that could delay shipments for weeks.

    I have installed the solid coupler and it definitely eliminates the rattle nicely.
