**********THIS PROGRAM IS IN EFFECT UNTIL NOVEMBER 30, 2017.********** 

CONDITION

On some 2015 model year Buick Encore, LaCrosse, Regal, and Verano; Cadillac ATS, CTS, ELR, Escalade, SRX and XTS; Chevrolet Colorado, Corvette, Cruze, Equinox, Impala, Malibu, Silverado, Sonic, Spark, SS, Suburban, Tahoe, Trax, and Volt; and GMC Canyon, Sierra, Terrain, and Yukon vehicles, a performance issue with the OnStar® module might impact the vehicle's battery life. This can cause a dead battery if the vehicle is not started for approximately 4 days. This condition can occur even if the OnStar® system is not active.

CORRECTION

Dealers are to replace the OnStar® module. If the customer does not have an active OnStar® subscription, the OnStar® module is to be deactivated after replacement.

VEHICLES INVOLVED

All involved vehicles are identified by Vehicle Identification Number on the Investigate Vehicle History screen 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.

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 to dealers through the GM GlobalConnect Recall Reports. Dealers will not have a report available if they have no involved vehicles currently assigned.

The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete this program is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this program.

PARTS INFORMATION

Parts required for this program are to be obtained from the Electronic Service Center (ESC). A Technical Assistance Center (TAC) case has been set up for the involved vehicles. The case number is identified in the customer letter. The customer is being instructed to inform the dealer of this number when scheduling an appointment so that the module can be ordered available on the scheduled appointment date.

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.
