Is anyone with an early model year 2014 (manufactured without the solid coupler/isolator) experiencing the supercharger rattle?

Cadillac CTS-V, Chevrolet Camaro ZL1 Recalled for Supercharger Failures
General Motors will recall the Chevrolet Camaro ZL1 and Cadillac CTS-V over a concern that the 6.2L engine’s supercharger could fail, causing the engine not to start or - in a worst case scenario – causing massive internal engine damage.
The Chevrolet Camaro ZL1 and the Cadillac CTS-V coupe, sedan and sport wagon are all powered by a supercharged 6.2L V8 that delivers 580 horsepower and 556lb-ft of torque in the Camaro and 556hp and 551lb-ft of torque in the Cadillac V lineup. The superchargers in these cars spin at incredible speeds to help make all of that power and, unfortunately, there is a problem with the bearings in the supercharger housings.

It seems that the grease which lubricates the internal bearing can become contaminated and when that happens, it fails to provide the proper amount of lubrication for the fast-spinning blower bearings. Over time, the increased friction can lead to excessive heat and if left unaddressed – this can lead to the blower seizing up. When the blower seizes up while the car is being driven, it can cause massive engine failure and nearly as bad, there could come a point where the owner goes to start his or her high performance GM and it will not crank.

The good news (if you really want to call it good news) is that this catastrophic engine failure in the Cadillac CTS-V and Chevrolet Camaro ZL1 does not happen suddenly. At first, the driver will notice a rattling sound under the hood that can come and go with more and less throttle. If the owner ignores the rattling sound and the condition worsens, the rattling will be superseded by a whining noise as the bearing fails. Once the bearing fails completely, the whining will stop – because the supercharger internals won’t be spinning anymore.

I "recently" heard that all ZL1s didn't have turbos and the recall isn't a recall but is actually a TSB.

I also heard the sky is falling and Bruce Jenner is changing back to a man. Unconfirmed...

Has anyone with a 14' had the SC replaced under warranty. BTW, I have 10k on mine. It recently started making noise. I have not looked/listened around under the hood, but it sounds like my old 96' 1500 PU when the tension pulley started to give up. I hear a sporadic clacking like two ball bearings slapping together. Or a sealed bearing momentarily seizing or catching. BTW, my car is #224 built in Aug 13'.
