Subject: 13313 – Special Coverage Adjustment – Supercharger Warranty Extension

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

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

ConditionSome 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 AdjustmentThis 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 InvolvedAll 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.
