Product Safety - Fuel Filter Fitting Disconnect

General Motors has decided that a defect which relates to motor vehicle safety exists in certain 2002 Chevrolet TrailBlazer, GMC Envoy, and Oldsmobile Bravada vehicles. Some of these vehicles have a condition where a fuel filter fitting may become disconnected. If this were to occur while attempting to start the engine, a no-start condition would result and fuel would be pumped out of the fuel filter onto the ground. If the fitting becomes disconnected while the vehicle is in motion, the engine would stop due to inadequate fuel supply and cause a loss of power steering assist. Under this condition, the vehicle could be maneuvered to a stop with manual steering efforts, and sufficient power brake assist would be maintained to bring the vehicle to a stop. If an ignition source were present, fuel leakage from a disconnected fuel filter fitting could result in a fire.

Dealers are to replace the fuel filter quick connect retainers.

Involved are certain 2002 Chevrolet TrailBlazers, GMC Envoys, and Oldsmobile Bravadas. Dealers should confirm vehicle eligibility through GMVIS (GM Vehicle Inquiry System) or GM Access Screen (Canada only) or DCS Screen 445 (IPC only) before beginning recall repairs. Not all vehicles are 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 recall bulletin. The customer name and address data furnished will enable dealers to follow-up with customers involved in this recall. Any dealer not receiving a computer listing with the recall 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 recall.

Important: An initial supply of parts required to complete this recall will be pre-shipped to involved dealers of record. This pre-shipment is scheduled to begin the week of May 6, 2002. Pre-shipped parts will be charged to dealer's open parts account.

Additional parts, if required, are to be obtained from General Motors Service Parts Operations (GMSPO). Please refer to your "involved vehicles listing" before ordering parts. 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.
