So if you have a AGM car the insert is the same color as the hood?

Yes, on ZL1's with paint code (GLJ) that do not have the Exposed Carbon Fiber Insert (B92), the insert will be painted the exact same color (GLJ), as the body of the car.

I have all 3 types of OEM inserts, black, gray and exposed. They all look good IMO. The gray does look nice. My car came with ECF, and it looks great, but I wouldn't cry if it were AGM or black.

"ALL ZL1's and CTSV's" as included in the link include the 2014 and 2015 models.

Both topics have been discussed a lot on this forum.

"According to TCC, GM will replace the superchargers on vehicles that have exhibited symptoms of bearing shaft failure free of charge. It will also, allegedly, be extending the warranty on all supercharged ZL1s and CTS-Vs to 10 years or 120,000 miles (whichever comes first), from the date of purchase. Officially, only 2009 to 2013 CTS-Vs and 2012 to 2013 ZL1s are suffering from this issue."

Thanks for the link, I re-read it and can understand why it would extend into 2014-15 models. But I also recall reading that the cause of bearing shaft failure had been fixed on 14-15 models. Also the "allegedly" troubles me. Is any of this confirmed specifically for the 14-15 models?

Here is the painted insert on my 2013...

I could understand the confusion, that is poorly worded (referencing up to 2013 and then throwing in "all". More importantly, it is not official from GM. The beginning of the GM bulletin was in the thread that you linked, but for more details, here is the official GM bulletin, should clear up the confusion, as it clearly mentions model years right up front. I apologize if I missed any updates to the below bulletin that would extend the coverage beyond the 2013 model year, but I haven't seen anything.

#13313: Special Coverage Adjustment - Supercharger Warranty Extension - (May 22, 2014)
Subject: 13313 – Special Coverage Adjustment – Supercharger Warranty Extension

Models: 2009-2013 Cadillac CTS
2012-2013 Chevrolet Camaro
Equipped with 6.2L V8 Engine (LSA)

--------------------------------------------------------------------------------

Condition
Some 2009-2013 model year Cadillac CTS and 2012-2013 model year Chevrolet Camaro vehicles, equipped with a 6.2L V8 engine (LSA), may have a condition where the engine’s supercharger may not function as designed. If this were to happen, the supercharger may develop a noticeable rattle noise at idle. The noise will typically go away when the engine RPM is raised slightly above idle. However, if left uncorrected, the problem, over time, may lead to contamination of the lubricating grease and cause the bearing to squeal. If left unaddressed, the bearing may overheat and can cause engine seizure or a no-start condition.

Special Coverage Adjustment
This special coverage covers the condition described above for a period of 10 years or 120,000 miles (193,000 km), whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership.

Dealers are to replace the supercharger. This repair will be made at no charge to the customer.

For vehicles covered by Vehicle Service Contracts, all eligible claims with repair orders on or after May 23, 2014, are covered by this special coverage and must be submitted using the labor operation codes provided with this bulletin. Claims with repair orders prior to May 23, 2014, must be submitted to the Service Contract provider.

Vehicles Involved
All involved vehicles are identified by Vehicle Identification Number on the Applicable Warranties section in GM Global Warranty Management system. Dealership service personnel should always check this site to confirm vehicle involvement prior to beginning any required inspections and/or repairs. It is important to routinely use this tool to verify eligibility because not all similar vehicles may be involved regardless of description or option content.

Parts Information
Parts required to complete this special coverage are to be obtained from General Motors Customer Care and Aftersales (GMCCA).

Note: To improve reliability of the supercharger one of the changes made was to go to a solid coupler between the geartrain and the drive pulley. A tradeoff to this improvement is that manual transmission vehicles may experience a flutter or rattle at low RPM (800-900) and high load (second or third gear). This flutter only lasts a moment and is a normal characteristic of this design.

IMPORTANT: GM requires dealers to approve or deny a reimbursement request within 30 days of receipt. If a reimbursement request is approved, the dealer should immediately issue a check to the customer and submit an appropriate warranty transaction for the incurred expense. If a reimbursement request is denied, the dealer MUST provide the customer with a clear and concise explanation, in writing, as to why the request was denied. The bottom portion of the Customer Reimbursement Request Form may be used for this purpose.

That is good info but it sure sucks for the small number of early 2014's that have the old SC part number but as you say are not covered by the TSB or the SC warranty extension...
