2001 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.

CAN NOT LOCATE FUEL LINES FOR GMC. WHEN I TRY TO FIND THE FUEL LINES IT IS MARKED THAT THEY ARE UN-AVAILABLE.LINES HAVE RUSTED OUT AND LEAK.HAD NEW FUEL PUMP INSTALLED WHEN THIS WAS NOTICED.

THE FOOT OPERATED PARKING BRAKE BROKE UNDER NORMAL WEAR AND TEAR. I HAD ESTIMATES THAT WERE WELL OVER $300 TO FIX, AND HAVE NOT YET HAD WORK DONE. I ONLY PARK ON LEVEL ROADS AND HOPE TRANSMISSION WILL HOLD IN PARK. I FEEL THIS MUST BE A DEFECTIVE PART. *TR

MY TRUCK RADIATOR STARTED TO SMELL AS IF IT HAD A LEAK. I TOOK IT TO A RADIATOR SHOP. THIS SHOP HAPPENS TO BE VERY CLOSE TO THE GM PLANT IN DAYTON, OHIO. THE MAN TOOK ONE LOOK AT THE TRUCK. HE EXPLAINED TO ME THAT ALL THE RADIATORS FOR THIS TRUCK FROM THE 2001 YEARS WERE SENT TO HIM PRIOR TO INSTALLING. HE SAID THEY HAD BEEN LEFT OUTSIDE FOR A PERIOD OF TIME AND ALL OF THEM HAD TO BE CLEANED OUT BECAUSE OF HEAVY RUST. HE STATED MINE MUST OF BEEN MISSED. THE RUST IN THE RADIATOR WAS SO THICK IT WAS LIKE MUD! HE REPLACED THE RADIATOR, HOSES AND EVEN HAD TO REPLACE THE RADIATOR FLUID RESERVOIR BECAUSE IT LITERALLY HAD INCHES OF RUST IN IT. THIS IS SOMETHING THE COMPANY KNEW ABOUT AND I SHOULD NOT OF HAD TO REPLACE IT. THE NEXT THING TO HAPPEN IS TO THE DRIVE TRAIN. THE TRUCK IS MAKING A WHINING NOISE - SOUNDS LIKE SOME TIRES DO. WE HAVE TAKEN IT TO SEVERAL PLACES TO REPAIR AND NO ONE CAN FIGURE OUT WHAT IS CAUSING THE SOUND. WE HAVE REPLACED SO MANY PARTS, MANY OF THEM MORE THAN ONCE IN A SHORT PERIOD OF TIME. I HAVE PUT OVER $3000 OF WORK IN THE TRUCK JUST OVER THE LAST MONTH AND AM NOT YET FINISHED. THE BRACKETS HOLDING THE REAR SUSPENSION IN PLACE ARE CRUMBLING IN MY HAND. THE MUFFLER IS LEAKING. IT IS STALLING FOR NO APPARENT REASON. AND IS IDLING VERY FAST EVEN THO IT HAS HAD REGULAR TUNE UPS AND MAINTENANCE. THE TAILGATE IS BROKEN - YOU CAN JUST PULL IT OFF THE TRUCK. THIS IS NOT NORMAL WEAR AND TEAR. THE WHINING CONTINUES WHENEVER IT IS BEING DRIVEN. WHATEVER HAPPENED TO COMPANIES BEING RESPONSIBLE FOR THE QUALITY OF THE VEHICLE! GOD KNOWS MOST OF US CANT BUY A NEW ONE AT $35,000+ TO. *TR

IN THE LAST 6 YEARS I HAVE HAD TO REPLACE THE BALL JOINTS; BOTH UPPER AND LOWER AND SHOCKS ALL AROUND FOR THE SECOND TIME. I DO NOT GO OUT 4-WHEELING AND BASICALLY DRIVE MY VEHICLE ONLY IN TOWN DRIVING. I DO NOT THINK THESE PARTS SHOULD BE WEARING OUT SO QUICKLY ON THIS VEHICLE. *KB

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

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.
