CAMPAIGN: PROPSHAFT/FUEL TANK CONTACT

NOTE: GM OF CANADA CAMPAIGN 96070 IS LOCATED BELOW THE U.S. VERSION

FMVSS NON-COMPLIANCE CAMPAIGN

SUBJECT: 96070 - PROPSHAFT/FUEL TANK CONTACT -----------------------------------

MODELS: 1995 4-DR, 4WD AND AWD CHEVROLET BLAZERS AND GMC JIMMYS ------------------------------------------------------- 1996 4-DR, 4WD AND AWD CHEVROLET BLAZERS, GMC JIMMYS ---------------------------------------------------- AND OLDSMOBILE BRAVADAS -----------------------

The Highway Safety Act, as amended, provides that each vehicle which is subject to a recall campaign of this type must be adequately repaired within a reasonable time after the customer has tendered it for repair. A failure to repair within sixty (60) days after tender of a vehicle is prima facie evidence of failure to repair within a reasonable time.

If the condition is not adequately repaired within a reasonable time, the customer may be entitied to an identical or reasonably equivalent vehicle at no charge or to a refund of the purchase price less a reasonable allowance for depreciation.

To avoid having to provide these burdensome remedies, every effort must be made to promptly schedule an appointment with each customer and to repair their vehicle as soon as possible. As you will see in reading the attached copy of the divisional letter that is being sent to customers, the customers are being instructed to contact the appropriate Customer Assistance Center if their dealer does not remedy the condition within five (5) days of the mutually agreed upon service date. If the condition is not remedied within a reasonable time, they are instructed on how to contact the National Highway Traffic Safety Administration.

DEFECT INVOLVED

General Motors has decided that certain 1995 and 1996 4-Door Chevrolet Blazers, GMC Jimmys and Oldsmobile Bravadas may fail to conform to FMVSS 301; "Fuel System Integrity". In certain types of vehicle crashes, the prop shaft may penetrate the fuel tank, resulting in a fuel leak. If an ignition source were present, a vehicle fire could result. Although we previously had conducted several tests of these model vehicle with no fuel leakage, a recent similar test resulted in a hairline fracture of the fuel tank with leakage greater than the amount permitted under FMVSS 301. Consequently, we have developed additional shielding for the fuel tank on these vehicles, which can be added without removing or disassembling the fuel system. To prevent the possibility of this condition occurring, dealers are to install additional shielding for the fuel tank. This can be added without removing or disassembling the fuel system.

VEHICLES INVOLVED

Involved are all 1995 4-Door, 4-Wheel Drive and All-Wheel Drive Chevrolet Blazers and GMC Jimmys and certain 1996 4-Door, 4-Wheel Drive and All-Wheel Drive Chevrolet Blazers, GMC Jimmys and Oldsmobile Bravadas built within the following VIN breakpoints:

NOTICE: Dealers should confirm vehicle eligibility through VISS (Vehicle Information Service System) or ServiceNet (GMC 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 State Motor Vehicle Registration Records. The use of such motor vehicle registration data for any other purpose is a violation of law in several states. Accordingly, you are urged to limit the use of this listing to the follow-up necessary to complete this campaign.

Notice: An initial supply of parts required to complete this campaign will be pre-shipped to involved dealers of record. This pre-shipment will occur the week of November 11, 1996. Pre-shipped parts will be charged to dealer's open parts account.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
