ZL1 supercharger recall?

Just recieved a phone call from my salesman. He told me that there will be a recall on all 2012 and 2013 ZL1 superchargers. Mine sounds absolutely horrible, and GM tech line has denied there is a problem with my car for a year now - all the GM mechanics admit it is F*^ked up. (it rattles so loud at idle that I can hear it in the car with windows up and I can feel it through the shift knob.) My salesperson said we will get new blowers and recieve a 120,000 mile warranty extension and 10 year warranty on supercharger. Anyone have any real solid info on this?

I am done with GM, after this, the car is going and I will never buy another. They still have not corrected my rear differential noise. They deny that is an issue also...

Give customer care a call. They'll respond if they really care but I'm guessing you'll hear the same response you get when you wish for a million dollars. .................................................. .....nothing.

It's all true. They are replacing them if they rattle. Talked to my dealer today.
They pulled up the bulletin today, it does exist.

I'm sorry your dealership treats you like crap. I would try finding another dealership before just swearing off all GM products. Good luck getting it fixed.

It's not a recall, just a service bulletin to repair cars showing signs of the problem. From the way I read it, the extended warranty is for the original supercharger not a new one as a new one won't have this specific problem.

So I haven't noticed an extreme rattle of anything from mine. I believe someone posted a video on here at some point of their engine with the rattle. I really didn't hear it then.

Can anyone suggest how I could look, listen, whatever, and see if there are signs that I have a problem please? I don't really want to trust the dealer here to make the determination. So far I really think I'm fine, but I'm not a mechanic and certainly not experience with blown motors.

Yup... all true.

Doesn't even matter if they are rattling or not. Get it replaced.

He lives on Oahu. His dealership choices are limited.
I can't tell, is there just one new car dealer on the island?

I called Chevrolet customer care. They stated as of now there is no recall just extended warranty 10 year/120,000 mile on the supercharger.
I hope the dealer service department won't give us a hard time is you just want it replace.

Correct, it is not a recall, just a service bulletin for the issue. If it is rattling they will more than likely replace it. That's what my dealer told me anyway.

Question is will they? Since the bulletin says to check for the rattle. GM stated the the shaft wear was as designed and only wore to a certain point and the debris was trapped where it wouldn't do any harm. Now they are saying that the debris can contaminate the bearings and cause them to fail. I would think they would change them all to prevent other engine damage if the bearings fail, but dont know if they will. I had no interest in changing my isolater out until this.

Here is the big question. Should I ask the dealer to replace it if I don't hear the rattle?

How are you going to get it replaced if you don't have the problem yet?

Thats like never buying from Samsung again since Best Buy wouldn't help me with the warranty.

The people at the dealership do not work for GM, they simply sell their products. If you don't like the dealer, go some place else. Thats always worked for me.

Remember, every car manufacture makes cars that have problems. Its how you deal with them that can seperate the good and bad experiences.

Yeah, they may not. I thought I read where all would be replaced regardless. Quite sure at some point they will have issues with the isolator and/or bearing.

When mine got replaced under warranty in December the new one had a solid isolator in it.

I saw that article in Motor Authority a few days ago & gave Ana Mae with the GM RECALL HOTLINE (1-800-458-8006) a call. Apparently, I was the 1st one to call regarding the ZL1 CAMARO supercharger "rattle"/Service Bulletin issue. They handle CADILLAC CTS-Vs as well. 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.

Thanks for the YouTube. Mine does not sound like that. At least now I know what to listen for.

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.

I believe he said the GM Tech Line denied his complaints/issues. I believe he said the dealership technician actually confirmed the issue, not gave him "crap". If the dealer is also getting info from GM directives, sounds like they were left out of the loop at the time.

I concur with him, I called GM tech line, gave them my VIN and got a denial. However, a local dealer confirmed my VIN actually is included, in conflict with GM Tech Line.

So.... sounds like the left hand doesn't know what the right hand is doing on this one.

No, only 12's and 13's

The 14's already have the solid coupler.

ZL1 Supercharger problems TSB#

I called my dealer today and asked them about this problem, and he of course was very rude and did not know anything about it. He asked what the TSB number was and I gave him the number I seen on this link which was #13-313, he laughed and said the number I gave him wasn't long enough to be a TSB nymber. Has anyone had any luck. Who should I contact?

It is a Service Bulletin and can be found in post #20
http://www.camaro5.com/forums/showthread.php?t=355197

Either print it out and take it with you, e-mail it to him, or read it to him verbatim over the phone.

the Service Bulletin is #13313 with no hyphen.

It's real. I printed it out and took it with me. The service manager read it, followed the steps it listed to determine if I had the rattle, and once he confirmed that I did per the instructions in the service bulletin, he agreed and ordered my SC.
