FUEL PUMP MODULE CORROSION CAUSING LEAKING FUEL AND FUEL VAPORS FROM THE TOP OF THE FUEL TANK. THIS IS DUE TO A DESIGN DEFECT AS THE FUEL PUMP MODULE SITS LOWER THAN THE HIGHEST POINT OF THE FUEL TANK AND MOISTURE AND DEBRIS ACCUMULATE ON TOP OF THE FUEL PUMP MODULE. THE TOP OF THE MODULE IS NOT MANUFACTURED WITH APPROPRIATE RUST-PROOFING MEASURES AND THE MATERIALS USED LEAVE IT PRONE TO RUSTING AND FAILURE, COMPROMISING THE SEAL AND ALLOWING FUEL TO ESCAPE FROM THE TANK. THIS POSES A FIRE HAZARD, ESPECIALLY IF FUEL IS ABLE TO REACH HEATED EXHAUST PIPES, ETC. I TOOK MY VEHICLE INTO A A GMC DEALERSHIP AND WAS DENIED REPAIR OF THE VEHICLE OR REIMBURSEMENT FOR REPAIR. THERE WAS A SPECIAL COVERAGE FOR THIS VEHICLE THAT HAS SINCE EXPIRED, PROVING THAT GM IS / WAS AWARE OF THE PROBLEM. GIVEN THE NUMEROUS COMPLAINTS OF THIS EXACT SAME ISSUE, THIS SHOULD BE ESCALATED TO RECALL STATUS DUE TO THE INHERENT SAFETY ISSUE AND FIRE RISK.

This PI communicates the requirement to provide a pico file to receive diagnostic assistance from TAC.

This Preliminary Information communication provides information to the technician about changing the tire and wheel size on vehicles. General Motors will only support a tire calibration for tires that have been sized, tested and designed for the vehicle in question and its applications. Technician should not use the information that is provided by the antilock braking system tire size selection.

Vehicle Wide Programming (VWP) is a new process to update software on GM Vehicles. It provides the ability via a single selection within Techline Connect to first identify which modules need updating and then proceed to updating affected modules (with some exceptions). The updating of modules is completed in parallel instead of the technician needing to update one module at a time. This allows a more streamlined approach for dealers and customers.

GM is receiving damaged (cracked or broken) transmission cores returned to the reman facilities. The damage is being caused either in the removal process by the technician, or inadequate packaging or shipping. This bulletin advises the dealers to be more careful not to damage the transmissions during removal and to package the core properly for return.

This service bulletin advises of a new fuel injection cleaner kit used for decarbonizing the intake valves to correct conditions of rough idle, Crank no start, extended crank or misfire, MIL with DTCs, and explains how Top Tier fuels should be used to reduce carbon build-up.

This bulletin provides information for use on a Product Assistance Claim (PAC), which is formerly known as a Product Allegation Resolution (PAR) claim.
