    I care very much about life.

    I spend 80% of my time, in the CTS-V, with the windows down, stereo pumping, and my foot planted to the floor. If you are driving in a manor where you can hear every noise you are in the wrong car. This car is not a BMW nor Mercedes Benz. It is a man's four door Corvette. Since the first Model-T was driven off of the assembly line every American car has made noise.

    Finally, a man's man! I don't drive around listening for little noises with a stethoscope either.

    Is this entirely accurate? It has been proven that the fail was a result of the rattle? I'm not sure that's entirely true. People have had their blowers replaced because of failure, but I'm not sure any of them were proven that the isolator was the cause. In fact, I thought just the opposite, that it has been proven that the noise and wear that occurs will not hurt the blower.

    I could be wrong, but if the rattle had been proven to destroy blowers GM would have changed the design or gotten the supplier to change the design a long time ago.

    Guys this is so old. The coupler will not cause a failure. If anything as the shaft wears it get quieter as there is less interaction with the spring. The shaft it rides on is a non issue and even if it fails it is not catastrophic. Go solid isolator or let it go.

    I too love this car for what it is. BAD ASSSSSSSSSS!

    I could be wrong, but isn't this what is implied by a solid isolator being standard in the LSA/Eaton powered new Camaro ZL1? I replaced mine and moved on.

    Meh... I enjoy hearing the isolator rattle.

    It is a satisfying reminder to me and an indicator to others as they walk past the V, hearing both the exhaust rumble and the engine chatter, that there is definitely NOT some wimpy V-6 idling under the hood. I guess it carries me back to days of solid lifter clatter and multiple carb setups sucking in air.

    If mind numbing engine silence is the desire - a Lexus may more preferable.

    My $.02

    Re: GM found a fix for the supercharger rattle!

    I don't find the noise acceptable on a $70,000 car...so I replaced it with a solid isolator. Work I shouldn't have had to do myself, but oh well. Now I'm hitting the gas and not thinking about it

    I would take it over fake engine noise pumped into through the audio system.

    Re: GM found a fix for the supercharger rattle!

    Katie, Please add me to this evolving list... Mine has rattled since purchased brand new off the floor and I have 4,700 miles on it... "Sounds like a Diesel" (clocking sound) at idle and also under throttle. Very embarrasing, to say the least. Same issue as everyone else has described. I've documented it with video but no point of posting as I think it's well known now. Cadillac "GM" should warranty this issue for a proper replacement and fix it under the mfg. warranty. Sadly I'm sure how bad the shaft will look like when pulled and a shame that it had to even "go through" that.. EATON / GM should have worked together better on this design and could only imagine all the metal that's accumulating everytime I turn it over. This could have been easily avoided again through proper design and a solid isolater. As user's mentioned the trade-off sound would be worth every penny, if even applicable. If it wasn't under the mfg. warranty, I would have already scheduled to have it fixed with a "solid isolater" but I don't want to void the warranty. What's disappointing is the "wear" & "damage" that is actually taking place on the shaft AND the isolater... Not acceptable "FOR ME" to spend $75 grand on a vehicle and just have to "put up with it" or "turn up the radio". Not a good excuse really for any new Cadillac CTS-V owner, that has a vehicle that has not been modified.
