INCORRECT FUEL LEVEL INDICATION. Cadillac Eldorado 1993

Subject: INCORRECT FUEL LEVEL INDICATION

Models: Certain 1993 Cadillac Eldorados and Sevilles

TO: ALL GENERAL MOTORS DEALERS:

General Motors of Canada Limited has determined that certain 1993 model Cadillac Eldorados and Sevilles may have a mispositioned fuel sending unit in die fuel tank. At less than one-quarter tank capacity, this can result in the unit giving an incorrect fuel level reading while the fuel level is actually decreasing. If this occurs, the vehicle may run out of fuel even though the fuel gauge indicates 8 to 11 litres remaining with 60 to 110 kms of driving range.

To prevent this condition from occurring, dealers are to realign the fuel sending unit in die fuel tank and replace the instrument panel cluster (IPC) Prom on all involved vehicles as per the Vehicles Involved and Service Procedure sections of this bulletin.

VEHICLES INVOLVED:

All 1993 model Eldorados and Sevilles built within the following VIN ranges require this campaign.

Year Model Plant From Through ---- ------ ----- ---- ------- 1993 Eldorado U PU600001 PU607181 1993 Seville U PU800001 PU812868

All affected vehicles have been identified by the VIN listing provided to involved dealers with this bulletin. Any dealer not receiving a listing was not shipped any of the affected vehicles.

DEALER CAMPAIGN RESPONSIBILITY:

All unsold new vehicles in dealer's possession and subject to this campaign must be held and inspected/repaired per the Service Procedure of this Campaign Bulletin before owners take possession of these vehicles.

Dealers are to perform this campaign on all involved vehicles at no charge to owners, regardless of kilometres traveled, age of vehicle, or ownership, from this time forward.

Owners of vehicles recently sold from your new vehicle inventory with no owner information indicated on the dealer listing, are to be contacted by the dealer, and arrangements made to make the required correction according to instructions contained in this bulletin. This could be done by mailing to such owners a copy of the owner letter accompanying this bulletin. Campaign follow-up cards should not be used for this purpose, since the owner may not as yet have received the notification letter.

In summary, whenever a vehicle subject to this campaign is taken into your new or used vehicle inventory, or is in your dealership for service in the future, please take the steps necessary to be sure the campaign connection has been made before selling or releasing the vehicle.

CAMPAIGN PROCEDURE:

Refer to Section 4 of the Service Policies and Procedures Manual for the detailed procedure on handling Product Campaigns. Dealers are requested to complete the campaign on all transfers as soon as possible.

OWNER NOTIFICATION:

All owners of record at the time of campaign release are shown on the attached computer listing and have been notified by first class mail from General Motors (see copy of owner letter included with this bulletin). The listings provided are for campaign activity only and should not be used for any other purpose.

Dear General Motors Customer:

General Motors of Canada Limited has determined that certain 1993 model Cadillac Eldorados and Sevilles may have a mispositioned fuel sending unit in the fuel tank. At less than one-quarter tank capacity, this can result in the unit giving an incorrect fuel level reading while the fuel level is actually decreasing. The vehicle may run out of fuel even though the fuel gauge indicates 8 to 11 litres remaining with 60 to 110 kms of driving range. Until you have your vehicle checked for this condition by your GM dealer, we recommend that you maintain a minimal fuel level of no less than 19 litres or one-quarter tank.

To correct this condition from occurring, dealers are to realign the fuel sending unit in the fuel tank and replace the instrument panel cluster (IPC) Prom on your vehicle at no cost to you. Also, as part of this service and to thank you for your cooperation, your dealer will fill your fuel tank at our expense.

This service will be provided for you at no charge.

Please contact your GM dealer as soon as possible to arrange a service date.

If parts are required, ask your dealer for details regarding their availability. If parts are not in stock, they can be ordered before scheduling your service date.

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