ENGINE KNOCKS WHEN STARTING COLD AND WHEN PULLING A TRAILER OR UNDER A LOAD. TOOK TRUCK TO DEALER AND WAS ADVISED THAT ALL THE 5.3 LITER ENGINES WILL EVENTUALLY DO IT. ALSO SAID THAT GENERAL MOTORS IS AWARE OF THE PROBLEM. I THEN CALLED GENERAL MOTORS AND ASKED THEM ABOUT THE PROBLEM. THEY SAID THAT IT WAS A CARBON BUILD UP. SO THEY HAD THE DEALER DO A DECARBONASATION WHICH REMOVES THE CARBON BUILD UP. WHEN IT WAS FINISHED, IT WAS WORSE THAN IT WAS BEFORE THEY WORKED ON IT. I CALLED GENERAL MOTORS BACK AND THEN THEY TOLD ME THAT THE PISTONS ARE SMALLER THAN NORMAL AND THAT THEY ARE SLAPPING AROUND IN THE CYLINDER WALLS CAUSING THE KNOCKING NOISE, AND THAT THEY ARE NOT DOING NOTHING ABOUT IT BECAUSE IT IS NOT DOING ANY DAMAGE TO THE MOTOR. THEY OFFERED ME AN EXTENDED WARRANTY ON THE DRIVE TRAIN AND I DECLINED IT. I PAID FOR A QUIET RUNNING GAS MOTOR, NOT ONE THAT SOUNDS LIKE A DIESEL. THE KNOCKING NOISE DECREASES THE TRADE IN VALUE, REGARDLESS IF IT IS DAMAGING THE MOTOR OR NOT. IF I WANTED A DIESEL I WOULD HAVE BOUGHT ONE. I HAVE BEEN GOING ROUND AND ROUND WITH GM AND THE DEALER FOR ALMOST TWO YEARS AND HAVE GOT NOWHERE.

THERE IS EXCESSIVE ENGINE NOISE, THAT THE DEALERSHIP HAS SAID IS ENGINE LIFTERS. ACCORDING TO THE DEALERSHIP GM HAS DIAGNOSED THE PROBLEM AS AN OIL PUMP ISSUE. THEY SAY THAT SUFFICIENT OIL IS NOT PUMPED TO THE ENGINE, SO THERE IS A LACK OF LUBRICATION. THE RESULT IS A TYPICAL "LIFTER STICKING" NOISE. THE DEALER SAYS THAT GM HAS NOT ISSUED ANY SORT OF A RECALL YET! IN FACT THEY SAY THERE IS NOT AN ADVERSE EFFECT OR DAMAGED BEING CAUSED TO THE ENGINE. I FIND THIS HARD TO BELIEVE AS PROPER LUBRICATION IS CRUCIAL TO MOTOR LONGEVITY. I BELIEVE THIS IS A RECALL ISSUE, AND THE LONG GM WAITS TO DIAGNOSE AND RECALL THIS PROBLEM, DAMAGE TO THIS VEHICLE WILL ONLY WORSEN. IF ALL ALLOWED TO GO LONG ENOUGH, I WOULD THINK GM WOULD BE LOOKING AT HAVING TO REPLACE MOTOR BLOCKS, RATHER THAN INSTALLING AN OIL PUMP THAT CAN HANDLE THE TASK OF GETTING OIL TO THE CRANK CASE. *TS *NLM ****DIMSII IVOQ ENTRY POSTED AFTER 12-12-02 CUT OVER TO ARTEMIS****761983

Status: closed (inferred from source dates) · Service Brakes, Hydraulic; Service Brakes, Hydraulic:power Assist:hydraulic:hoses, Lines/piping, And Fittings
The Office of Defects Investigation (ODI) received Defect Petition DP10-003 on March 2, 2010, requesting the investigation of model year (MY) 2003 Chevrolet Silverado 2500HD 4WD pickup trucks for corrosion failures of the vehicle brake lines.DP10-003 was granted and on March 30, 2010, Preliminary Evaluation PE10-010 was opened on more than six million model year 1999 through 2003 light trucks and sport utility vehicles manufactured and sold by General Motors Corporation (GM).On July 2, 2010, ODI received GM's response to an information request, which included GM's assessment of the frequency and safety consequences of the alleged defect. GM stated that:(1) the brake system of the subject vehicles is split front/rear and should a brake pipe suddenly fail for any reason, the affected vehicle would be capable of stopping with the pressure supplied by the remaining circuit; (2) the subject vehicles were designed to meet the hydraulic circuit partial failure requirements of Federal Motor Vehicle Safety Standards 105 and 135, Light Vehicle Brake Systems; and (3) should a brake fluid leak occur for any reason, the brake system malfunction indicator lamp (MIL) would illuminate and warn the driver before the brake fluid level was low enough to cause a loss of line pressure.ODI's and GM's analysis indicates that 85 percent of the complaints occurred on vehicles used primarily in States that use salt on the roads during Winter months (Connecticut, Delaware, District of Columbia, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia and Wisconsin).Overall the complaint rates per 100,000 vehicles for Salt Belt States is 43.0 and Non-Salt Belt is 3.0.In approximately 25 percent of the complaints the brake pipe failure occurred suddenly, with no warning (i.e., no MIL, Brake Fluid Loss Warning), and resulted in extended stopping distances.In 30 of these the increase in stopping distance that resulted was a factor in the crash and in 10 others the vehicle was intentionally steered off the road or into another lane of travel in order to avoid a crash.This investigation has been upgraded to an Engineering Analysis (EA11-001) for subject vehicles sold or currently registered in Salt Belt States to further assess the scope, frequency and safety risks associated with sudden failures of corroded brake pipes that can result in decreased brake effectiveness. ODI will continue to gather information on subject vehicles outside the Salt Belt as well.

ODI OPENED PE03-057 TO ASSESS PARKING BRAKE INEFFECTIVENESS IN THE SUBJECT VEHICLES.THESE VEHICLES ARE EQUIPPED WITH FOUR WHEEL DISC BRAKES THAT INCORPORATE A SINGLE-SHOE DRUM-IN-HAT PARKING BRAKE INDEPENDENT OF THE SERVICE BRAKES.COMPLAINT AND WARRANTY DATA INDICATE THAT THE PARKING BRAKE LININGS TEND TO WEAR OUT EARLY IN THE LIFE OF THE VEHICLE (AT AN AVERAGE OF 24 MONTHS IN SERVICE), REDUCING THE PARKING BRAKE SYSTEM'S TORQUE BELOW THAT NEEDED TO IMMOBILIZE THE VEHICLE.GM HAS ATTRIBUTED THIS ACCELERATED WEAR TO FOREIGN MATERIAL INTRUSION AND A FAILURE OF THE BRAKE SHOE TO PROPERLY SELF-CENTER WITHIN ITS BRAKE DRUM.EFFECTIVE WITH THE START OF MY 2003 PRODUCTION, A NEWER REDUCED FORCE HOLD-DOWN CLIP WAS INTRODUCED TO FACILITATE BRAKE SHOE DISENGAGEMENT FROM THE DRUM SURFACE.THIS PART IS ALSO AVAILABLE AT THE SERVICE LEVEL FOR THE MY 1999-2002 VEHICLES.GM HAS INDICATED THAT THE PAKING BRAKE IS INTENDED TO OPERATE IN CONJUNCTION WITH THE TRANSMISSION TO IMMOBILZE PARKED VEHICLES, AND THAT IN MANY CASES, ACCELERATED PARKING BRAKE LINING WEAR IS CAUSED BY ROUGH USE, VEHICLE MODIFICATIONS, AND DRIVING WITH THE PARKING ENGAGED. ODI HAS UPGRADED THE PRELIMINARY EVALUATION TO AN ENGINEERING ANALYSIS TO GATHER FURTHER INFORMATION CONCERNING PARKING BRAKE USAGE FACTORS AND THE CIRCUMSTANCES SURROUNDING THE SEVENTEEN REPORTED VEHICLE CRASHES.

THIS INVESTIGATION INVOLVES THE GENERAL MOTORS CORPORATION (GM)THROTTLE BODY (TB) UTILIZED IN MODEL YEAR (MY) 1999-2002 SILVERADO, SIERRA, TAHOE, SUBURBAN, AVALANCHE AND YUKON (SUBJECT VEHICLE(S)) WITH 4.8L, 5.3L, AND 6.0L ENGINES. THE TB VALVE MAY INTERMITTENTLY STICK IN A CLOSED POSITION.IN SUCH A SITUATION, AN OPERATOR MAY APPLY ADDITIONAL ACCELERATOR PEDAL FORCE TO INCREASE ENGINE SPEED.THE APPLICATION OF ADDITIONAL ACCELERATOR PEDAL FORCE, TO OPEN A STUCK THROTTLE VALVE, MAY OPEN THE THROTTLE VALVE MORE THAN INTENDED AND, IN TURN, ACCELERATE THE ENGINE AND VEHICLE MORE THAN INTENDED AND REASONABLY EXPECTED BY THE DRIVER.ON AUGUST 1, 2002, THE OFFICE OF DEFECTS INVESTIGATION (ODI), OF THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION (NHTSA), OPENED THIS ENGINEERING ANALYSIS.THE INVESTIGATION REVEALED THAT TWO FACTORS MAY CAUSE THE DEFECT: 1) TB MANUFACTURING PROCESS PROBLEMS; AND 2) ACCUMULATION OF DEPOSITS (A PCV SYSTEM BY-PRODUCT) ON OR AROUND THE TB THROTTLE VALVE AND BORE.ODI CONCLUDES THAT THE TB PERFORMS IN A DEFECTIVE MANNER AFTER ANALYZING GM?S DATA SUBMISSIONS, AND TEST DATA COLLECTED BY THE VEHICLE RESEARCH AND TEST CENTER (VRTC).FIFTY-NINE CRASHES ARE ALLEGED TO HAVE OCCURRED AS A RESULT OF GM?S TB DEFECT.THE MAJORITY OF THE CRASHES INVOLVE A SINGLE VEHICLE, ENGAGING IN A CLOSE QUARTER VEHICLE MANEUVER (OR LOW SPEED), AND CAUSING ONLY MINOR PROPERTY DAMAGE.FOUR OUT OF THE FIFTY-NINE CRASHES INVOLVE INJURY, AND THOSE INJURIES WERE MINOR.ALTHOUGH GM?S TB IS DEFECTIVE, BASED ON THE EVIDENCE GATHERED, ODI HAS FOUND THAT THE ACCELERATOR PEDAL FORCE REQUIRED TO OPEN A STUCK THROTTLE VALVE IS NEGLIGIBLE, AND THE THROTTLE VALVE DOES NOT STICK IN THE OPEN POSITION.THEREFORE THIS ENGINEERING ANALYSIS (EA02-015) WILL BE CLOSED AT THIS TIME.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT A SAFETY-RELATED DEFECT DOES NOT EXIST.FOR A DETAILED DISCUSSION OF THE TB COMPONENT AND TESTING, PLEASE SEE THE ATTACHED REPORT.
