2000 GMC Sonoma

ODI OPENED PE02-066 TO EVALUATE THE SCOPE AND CONSEQUENCE OF ENGINE POWER-LOSS DUE TO FUEL STARVATION INDUCED BY IN-TANK MODULAR FUEL PUMP STRAINER RESTRICTION.THE SUBJECT PUMPS USE AN EXTERNAL ?SOCK? STRAINER TO FILTER FUEL FLOWING TO THE PUMP INLET.THIS FILTER CAN SOMETIMES BECOME CLOGGED, RESULTING IN A REDUCED FLOW OF FUEL TO THE ENGINE.GM HAS SUBSEQUENTLY MODIFIED THE STRAINERS TO REDUCE THIS RESTRICTION.ANALYSIS OF THE ODI COMPLAINT DATABASE SHOWS THAT DESPITE THESE RESTRICTIONS, THE SUBJECT VEHICLES STALL AT A RATE THAT IS COMPARABLE TO THOSE OF MANY PEER VEHICLES.ADDITIONALLY, NONE OF THE RELEVANT WARRANTY REPAIR RATES EXCEED 1% AT 36 MONTHS OF EXPOSURE.ONE RELATED CRASH INVOLVES A STALLED VEHICLE THAT WAS REAR-ENDED ON THE ROADWAY, WHILE THE REMAINDER INVOLVED MINOR COLLISIONS OR SCRAPES.THE SOLE INJURY CONSISTED OF BRUISING FROM A LOW SPEED FRONTAL CRASH. GIVEN THESE CIRCUMSTANCES, FURTHER EXPENDITURE OF AGENCY RESOURCES IS NOT JUSTIFIED IN THIS MATTER.THE PRELIMINARY EVALUATION IS THEREFORE CLOSED.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT NO SAFETY-RELATED DEFECT EXISTS.THE AGENCY WILL TAKE FURTHER ACTION IN THE FUTURE IF WARRANTED.

I HAD A NEAR DEATH ACCIDENTS (TWICE) DUE TO CATASTROPHIC BRAKE LINE FAILURE FROM SEVERELY RUSTED BRAKE LINES THE FRONT LEFT AND THE INTERMEDIATE LINE FROM FRONT TO REAR SECTION ON TOP OF FRAME RAIL. FIRST INCIDENT WAS AT SPEED OF 45 MPH ON HIGHWAY WITH HARD STOP REQUIRED TO AVOID STOPPED TRAFFIC AHEAD. SECOND FAILURE WAS MORE INSIDIOUS WITH PROGRESSIVE BRAKE LINE RUST THROUGH/ LEAK SPOT TO REAR BRAKE LINES WITH FIN THROUGH AND FAILURE. THIS IS NOT COMPLICATED ... SIMPLY SUBSTANDARD MATERIALS FOR ONE OF THE MOST CRITICAL COMPONENTS IN A VEHICLE. IT SHOULD NOT MATTER WHAT CONDITIONS ARE (IE SALT, COLD, ETC; DESIGN AND MATERIALS SHOULD BE MANDATED FOR BRAKE LINES NOT TO RUST THROUGH. THERE ARE MATERIALS WHICH COULD BE USED TO ACCOMPLISH THIS, PARTICULARLY FOR NORTHERN REGIONS WITH SALT ON ROADS. THE ENTIRE BRKE LINE SYSTEM IS ON THIS VEHILCLE (AND OTHERS) IS AN UNNECESSARY AND AVOIDABLE PUBLIC SAFETY HAZARD. SURELY THERE HAVE BEEN DEATHS RESULTING FROM FAILURE, I WAS LUCKY AND HAD TO MANEUVER STRIGHT THROUGH BETWEEN 2 STOPPED VEHICLES AS I HAD NO OTHER OPTION WITH NO BRAKES. ALSO, ALL VEHICLES SHOULD BE REQUIRED TO HAVE HANDLE OPERATED PARKING/EMERGENCY BRAKE LEVERS , AS THE FOOT OPERATED ONE IN THIS VEHICLE WAS USELESS, BUT A PULL TYPE, HAND OPERATED BRAKE HANDLE WOULD HAVE BEEN READILY ACCESSIBLE AND LIKELY PREVENTED NEAR DEATH INCIDENT.

This Preliminary Information communicates to the dealer the process for downloading or updating operating software for the Tire Pressure Monitor, Active Fuel Injector tester, multi media tester, PICO Scope, GR8 starting/charging tester  and Vehicle Data Recorder tools, giving website address and step by step instructions to complete the update.

This Preliminary Information communication provides information to the technician about vehicles that the Heater-Vent-Air Conditioning blows warm air. Before calling General Motors Technical Assistance Center technician will need to have high and low pressures, outside temperature, humidity, and vent temperature.

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.
