Customer Satisfaction - OnStar Theft Notification Battery Run Down

Some 1999 and 2000 GMC Yukon Denali and Cadillac Escalade vehicles may have the potential of exhibiting a battery drain condition when a vehicle theft event causes a phone call to be initiated by the OnStar Automatic Theft Notification feature, and the call is not completed,

To correct this condition, customers will be mailed a letter than instructs them to press the OnStar button in their vehicle for a new configuration. Customers that do not have OnStar activated will have their dealer modify the VIU harness. Dealers are to perform the modification procedure in this bulletin on all inventory vehicles.

Involved are certain 1999 and 2000 GMC Yukon Denali and Cadillac Escalade vehicles built within these VIN breakpoints:

Important: Dealers should confirm vehicle eligibility through GMVIS (GM Vehicle Inquiry System) or GM Access Screen (Canada only) prior to beginning campaign repairs. [Not all vehicles within the above breakpoints may be involved.]

Involved vehicles have been identified by Vehicle Identification Number. Computer listings containing the complete Vehicle Identification Number, customer name and address data have been prepared, and are being furnished to involved dealers with the campaign bulletin. The customer name and address data furnished will enable dealers to follow up with customers involved in this campaign. Any dealer not receiving a computer listing with the campaign bulletin has no involved vehicles currently assigned.

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

No parts are required for this campaign

Important: THIS PROCEDURE IS FOR INVENTORY VEHICLES AND CUSTOMERS THAT DO NOT HAVE ONSTAR ACTIVATED. DO NOT PERFORM THIS CAMPAIGN ON CUSTOMER VEHICLES THAT HAVE ONSTAR ACTIVATED.

1. Open the IP storage compartment door. Disconnect the check strap and remove the IP storage compartment.

OnStar Emergency Services

In an emergency, simply press the emergency services button on your OnStar console. Upon receiving the call, an OnStar advisor at the OnStar Center will locate your vehicle and assess the situation. If necessary, the Advisor will alert the nearest emergency services provider. If the Advisor cannot speak with anyone in the vehicle, they will dispatch emergency assistance. For this reason, the OnStar Emergency button should be used only in life threatening situations.

Notification of Air Bag Deployment

If a front air bag deploys, a priority emergency signal is sent automatically to the OnStar Center by the OnStar system. An Advisor will attempt to communicate with you. If you are unable to respond, or report an emergency, the Advisor will determine the exact location of your vehicle, call the nearest emergency services provider, and describe the situation and your location. If necessary, the Advisor will transfer your call to the emergency services operator.

Theft Notification

Due to the high incidence of false alarms, this original content feature is no longer active in your vehicle. The original factory installed Theft Deterrent System is still functional. Operation of this system is explained in your vehicle's Owner's Manual. The OnStar Stolen Vehicle Tracking feature is still functional.

Stolen Vehicle Tracking

OnStar can track your vehicle if it is stolen. Once you alert the OnStar Center that your vehicle has been stolen, we will notify the police and help them to locate the vehicle to minimize potential damage. Call 1-888-ONSTAR (1-888-466-7827) to report your vehicle has been stolen. The OnStar advisor will then initiate tracking in order to locate and track the vehicle and will provide this information to the appropriate police authority.

Note: To protect subscriber privacy, OnStar will not provide the location of a vehicle to anyone other than a law enforcement authority.

Roadside Assistance with Location

If your vehicle breaks down, has a flat tire or runs out of gas, simply press the OnStar Center button on the handset to reach the OnStar Center. An Advisor at the OnStar Center will pinpoint your location using an on-line digital map and quickly dispatch the appropriate service provider -- for example, tow truck, glass replacement service, taxicab, tire dealer or GM dealer -- to your location.

Dear GMC/Cadillac Customer:

We recently identified that the OnStar system in your 2000 GMC Yukon Denali/Cadillac Escalade requires an upgrade to prevent the possibility of battery drain. Battery drain can occur when the factory installed alarm system is inadvertently triggered. This may cause the OnStar computer to energize and drain the battery. This could result in the failure of your vehicle to start.

Upgrading your OnStar system is simple and should only take a few minutes. Just start your vehicle and press the blue OnStar button. Request that the OnStar advisor send the Battery Protection Upgrade data to the OnStar computer in your vehicle. The OnStar advisor will then perform the upgrade, which will take approximately 4 minutes, via cellular signal.

This data upgrade will eliminate the potential for battery drain. All aspects of your Yukon Denali/Escalade and your OnStar system remain completely functional, as well as all other safety, security, and convenience services provided by OnStar.

If you have not activated your pre-paid OnStar subscription, and would like to, please press the blue OnStar button and wait until the OnStar Call Center advisor responds. If you do not wish to press the OnStar button for this software fix, or if you do not intend to activate your OnStar subscription, it will be necessary for you to visit your local GMC/Cadillac dealer for a modification to your Yukon Denali/Escalade.

We always strive to build the best vehicles possible and we want to make your Yukon Denali/Escalade ownership experience the best in the world. We are pleased to be able to use modern technologies to minimize any inconvenience to you. If you have any questions about this procedure, please ask the OnStar advisor when you press the blue OnStar button or you can contact the appropriate Customer Assistance Center at the number listed below:

The attached customer reply card identifies your vehicle. If you have your GMC/Cadillac dealer perform this upgrade, presentation of this card to your dealer will assist in making the necessary correction in the shortest possible time. If you no longer own this vehicle, please let us know by completing the card and returning it to us in the postage paid envelope.

We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your continued satisfaction with our products.

Dear GMC/Cadillac Customer:

We recently identified that the OnStar system in your 1999 GMC Yukon Denali/Cadillac Escalade requires an upgrade to prevent the possibility of battery drain.

Upgrading your OnStar system is simple and should only take a few minutes. Just start your vehicle and press the blue OnStar button. Request that the OnStar advisor send the Battery Protection Upgrade data to the OnStar computer in your vehicle. The OnStar advisor will then perform the upgrade, which will take approximately 4 minutes, via cellular signal.

Battery drain may occur when the factory installed alarm system is inadvertently triggered. This may cause the OnStar computer to energize in preparation to place a phone call to OnStar. If the driver resets the alarm before the phone call is completed, it could rain the battery causing your vehicle not to start.

This data upgrade will eliminate the potential for battery drain by removing the automatic theft notification capability (enclosed is an insert for you OnStar Owner's Manual). Your factory installed Yukon Denali/Cadillac Escalade theft deterrent system remains completely functional along with all other safety, security, and convenience services provided by OnStar. Should your vehicle be stolen, you can still call OnStar and the advisor can track your vehicle and, working with the police, assist in a speedy recovery.

If you have not activated your pre-paid OnStar subscription, and would like to, please press the blue OnStar button and wait until the OnStar Call Center advisor responds. If you do not wish to press the OnStar button for this software fix, or if you do not intend to activate your OnStar subscription, it will be necessary for you to visit your local GMC/Cadillac dealer for a modification to your Yukon Denali/Escalade.
