Make	Model	Model Year		RPO	Description
		From	To
Chevrolet	Camaro	2016	2016	LGX/LTG	V6/L4-Turbo

Involved vehicles are marked "open" on the Investigate Vehicle History screen in GM Global Warranty Management system. This site should always be checked to confirm vehicle involvement prior to beginning any required inspections and/or repairs.

Condition

Certain 2016 model year Chevrolet Camaro vehicles, equipped with a V6 or L4-Turbo engine (RPO LGX or LTG), may have a condition in which water can migrate within the forward lamp wire harness and intrude into the fan control module connector and can lead to connectivity loss and terminal corrosion. If a customer experiences this condition, an SES light (DTC P0480 and possibly P0691) can illuminate. In addition, if the loss of the engine cooling fan operation is not corrected, the condition can lead to engine overheating or engine damage.

Correction

Inspect connector and ground terminals for presence of water or corrosion. Clean and add a sealant and a patch, or replace the wire harness and/or cooling fan module or assembly if necessary.

DEALER RESPONSIBILITY

All new, used, GM Certified Used, courtesy transportation vehicles, dealer shuttle vehicles, etc. in dealers' possession and subject to this recall must  be held and inspected/repaired per the service procedure of this bulletin before  customers take possession of these vehicles. Involved vehicles must be held and not delivered to customers, dealer-traded, released to auction, used for demonstration, or any other purpose.

All GM Certified Used vehicles currently in the dealers' inventory within the Certified Pre-Owned Inventory System (CPOIS) will be de-certified and must be held and remedied per the service procedure in this bulletin. Upon submitting an accepted/paid warranty transaction in the Global Warranty Management (GWM) system, the vehicle can be re-certified for sale within the CPOIS system, or once again be used in the CTP program.

Dealers are to service all vehicles subject to this program at no charge to customers, regardless of mileage, age of vehicle, or ownership, through August 31, 2018. Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer information indicated on the involved vehicle listing, are to be contacted by the dealer. Arrangements are to be made to make the required correction according to the instructions contained in this bulletin. A copy of the customer letter is provided in this bulletin for your use in contacting customers. Program follow-up cards should not be used for this purpose, since the customer may not as yet have received the notification letter.

In summary, whenever a vehicle subject to this program enters your vehicle inventory, or is in your facility for service through August 31, 2018, you must take the steps necessary to be sure the program correction has been made before selling or releasing the vehicle.
