SERVICE INFORMATION
This bulletin has been revised to provide instructions on programming and activating the new vehicle communication interface module. Please discard all copies of bulletin 15086.
When a customer calls to schedule an appointment for this program, please place your order for the module. This will ensure that the necessary parts will be available on the scheduled appointment date. It is important to note that this program is independent from the OnStar 3G /4G Hardware Program, impacting a separate group of vehicle owners. For this Customer Satisfaction Program, dealers are responsible for ordering the part.
THIS PROGRAM IS IN EFFECT UNTIL DECEMBER 31, 2017.
CONDITION
On certain 2015 model year GM passenger cars and light duty trucks, equipped with Gen 10 OnStar®, the embedded phone flash memory chip may become corrupted, causing the OnStar® system to become inoperative.
CORRECTION
Dealers are to replace and program the vehicle communication interface module (VCIM).
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.
