Customer Satisfaction Program-VSES Pump Assembly Misbuild

THIS PROGRAM EXPIRED SEPTEMBER 1, 2003.

Dealers are to replace ABS assembly.

Involved are certain 2003 Cadillac CTS model vehicles equipped with VSES. The following list includes the dealers of record and VINs involved in this program:

Important: Dealers should confirm vehicle eligibility through GMVIS (GM Vehicle Inquiry System) or DCS Screen 445 (IPC only) prior to beginning program 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 program bulletin. The customer name and address data furnished will enable dealers to follow up with customers involved in this program. Any dealer not receiving a computer listing with the program 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 program.

Parts required to complete this program are to be obtained from General Motors Service Parts Operations (GMSPO). Please refer to your "involved vehicles listing" before ordering requirements. Normal orders should be placed on a DRO = Daily Replenishment Order. In an emergency situation, parts should be ordered on a CSO = Customer Special Order.

Important: For additional information and illustrations, refer to the appropriate subsections of the 2003 Cadillac CTS Service Manual. At the present time, the Service Manual can only be accessed electronically via Service Information (SI). A printed version of the Service Manual will be available in the near future.

Place a Program Identification Label on each vehicle corrected in accordance with the instructions outlined in this Product Program Bulletin. Each label provides a space to include the program number and the five (5) digit dealer code of the dealer performing the program service. This information may be inserted with a typewriter or a ball point pen.

Put the Program Identification Label on a clean and dry surface of the radiator core support in an area that will be visible to people servicing the vehicle.

Additional Program Identification Labels for US dealers can be obtained from Dealer Support Materials by either ordering on the web from DWD Store, gm-dealerworld.com, or calling 1-866-700-0001 (Monday-Friday, 8:00 am to 5:00 pm EST).

Additional Program Identification Labels for IPC dealers can be obtained from your Regional Marketing Office.

The General Motors Courtesy Transportation program is intended to minimize customer inconvenience when a vehicle requires a repair that is covered by the New Vehicle Limited Warranty. The availability of courtesy transportation to customers whose vehicles are within the warranty coverage period and involved in a product program is very important in maintaining customer satisfaction. Dealers are to ensure that these customers understand that shuttle service or some other form of courtesy transportation is available and will be provided at no charge. Dealers should refer to the General Motors Service Policies and Procedures Manual for Courtesy Transportation guidelines.

Submit a Product Program Claim with the information indicated below.

Refer to the General Motors WINS Claim Processing Manual for details on Product Recall Claim Submission.

For US

Customers will be notified of this program on their vehicles by General Motors (see copy of customer letter included with this bulletin).

For IPC

Letters will be sent to known owners of record located within areas covered by the US National Traffic and Motor Vehicle Safety Act. For owners outside these areas, dealers should notify customers using the attached suggested dealer letter.

All unsold new vehicles in dealers' possession and subject to this program MUST be held and inspected/repaired per the service procedure of this program bulletin BEFORE customers take possession of these vehicles.

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, 2003.

Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer information indicated on the dealer 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. This could be done by mailing to such customers a copy of the customer letter accompanying this bulletin. 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 dealership for service prior to September 1, 2003, you must take the steps necessary to be sure the program correction has been made before selling or releasing the vehicle.
