DESCRIPTION:
CUSTOMER SATISFACTION PROGRAM #06523 – MARCH 27, 2006

Certain 2006 Chevrolet Corvette model vehicles equipped with 6.0L V8 (RPO LS2 - VIN U) or 7.0L V8 (RPO LS7 – VIN E) engine and manual transmission may have a condition in which the flywheel may have been incorrectly machined, resulting in insufficient clearance for clutch cover self adjustment, reducing clutch life.
This program will expire on March 31, 2007.
Dealers are to inspect and, if necessary, replace the engine flywheel.
Refer to Customer Satisfaction Program #06523 for further information
EFFECTIVE DATE:
Initial owner mailing is scheduled to begin: 4-3-06
GENERAL INFORMATION:
Parts required to complete this program are to be obtained from General Motors Service Parts Operations (GMSPO). Normal orders should be placed on a DRO = Daily Replenishment Order. In an emergency situation, parts should be ordered on a CSO = Customer Special Order.
Part Number Description Quantity/Vehicle
12571611 Flywheel, Eng 1
IMPORTANT: Due to the small number of vehicles involved and due to limited initial parts availability, Dealers are encouraged not to order program parts for use as shelf stock. Parts should only be ordered when inspection determines that it is necessary to replace the flywheel.

VEHICLES INVOLVED
Involved are certain 2006 Chevrolet Corvette model vehicles equipped with 6.0L V8 (RPO LS2 -
VIN U) or 7.0L V8 (RPO LS7 – VIN E) engine and manual transmission and built within these
VIN breakpoints:
2006 Chevrolet Corvette 65115878 65121102
Important: Dealers are to confirm vehicle eligibility prior to beginning repairs by using the GM
Vehicle Inquiry System (GMVIS). Not all vehicles within the above breakpoints may
be involved.
For dealers with involved vehicles, a listing with involved vehicles containing the complete
vehicle identification number, customer name, and address information has been prepared and
will be provided through the applicable system listed below. Dealers will not have a report
available if they have no involved vehicles currently assigned.
Thanks for the clarification. This news has now made me very happy this morning. Now it looks like my Z will escape an "invasive probing". Looks like my VIN was built somewhat ahead of the starting VIN. Since my engine was just built mid-Jan, GM has caught and recognized this potential problem due lack of QC very quickly.

I think i'm clear too my vin E665121291. It's early I could be wrong.
Have to say it: glad I have an 05. Sorry but when people read about problems with the 05's they always say glad I got an 06 so I thought I'd return the favor. Actually, like to have at least one of each.

You appear to be after the range about as many cars as I am ahead of the range. I hope GM has picked an all inclusive range on the VINs potentially affected. I would hate to have an out of spec flywheel and not even be identified as a VIN to be notified and inspected.

Likewise for the 2001 Z06. I know as I still own one. It is a solid car 37k miles after the famous rering job.

So do you think the cars w/vin#s after had the correct parts while in production-how do they determine the break point?
Unfortunately, my car is IN the recall. It was invoiced on Mar 8 but never delivered. I'm told they trucked it (and many other cars) to Wickes (sp?) in Mich for repairs because BG doesn't have facilities to repair a whole bunch of cars.
Now my car is in a black hole and I don't know when it will fall out.

I have no clue. GM must have spotted the problem at some point in time but could only get correctly dimensioned flywheels to the engine plants by some later date. More difficult would be to identify when the problem flywheels started IMHO. I am still not real confident that my VIN is truly in the clear. I wonder how much disassembly is needed by the dealer to do this flywheel/clutch recall inspection????

I have been told the flywheel replacement job is 4 hours. Don't know how they inspect it. Is there an access plate?
Mine was fixed at the plant the day of my originally scheduled R8C delivery. I saw it being worked on during my factory tour. They dropped the entire torque tube/rear assembly and replaced the flywheel. I understand that the flywheel was rotating eccentrically and thus wearing the clutch face rapidly. All appears well so far.
I don't think that there is any way of getting a look at the flywheel unless you remove the bell housing at the end of the torque tube.
Well this sucks. My number is 20695 and had the car for about 3 weeks. So now what? Do I wait for a letter from GM? Do I print this and call the dealer? My dealer is about an hour from me (Kelley Chevrolet) but Lou Bachrodt is about 10 minutes from me. Do you think it makes a difference where I take it? And do you think they will be able to find it if their is a problem or will they just go through the motions?

I'm not sure the vin break points mean anything I have 2 Z's comming w/vins after breakpoint that were still pulled and had replacement done -both invoiced 1st week in march and still no show.
My new coupe, which is waiting at NCM for pick up in a couple of weeks is just out of the range, I think. It's VIN is 65122020. Hope I'm right; it's a 2.5 K mile drive home.
My father who knows alot more about cars claims that this should only be effecting the cars with manuel transmissions. I told him I don't believe he's correct and you guys would be posting that. So is this problem for automatics also? What can I tell him? he feels the flywheen only effects the manuel cars.
