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.

I SWERVED TO MISS A DEER AND I HIT A TREE RUNNING 47 MPH AND MY AIR BAGS DIDN'T DEPLOY AND NO ONE CAN TELL ME WHY. MY HUSBAND AND I WERE VERY LUCKY BUT WHY DIDN'T THE AIR BAGS DEPLOY? MY HUSBAND WAS OUT OF WORK FOR 5 MONTHS DUE TO TORN LIGAMENTS IN HIS SHOULDERS AND STILL HAS TO HAVE SURGERY.

TWO YEARS AGO I HAD A SEVER ACCIDENT THAT CAUSE ME TO HIT ANOTHER CAR AND SPIN AROUND. THE GMC DEALER SAID THE CAUSE WAS RUSTED OUT BRAKE LINES. TODAY IT HAPPENED, BUT I WAS LUCK ENOUGH TO BE JUST PULLING INTO MY PARKING SPOT WHEN IT HAPPENED. THE BRAKE LINE MUST HAVE RUSTED OUT AGAIN BECAUSE I PUMPED THE BRAKE AND NOTICED IT COMING OUT OF THE LEFT REAR LINE. THIS IS VERY DANGEROUS BECAUSE IT WILL LIKELY ONLY HAPPEN WHEN YOU ARE IN AN EMERGENCY SITUATION. THERE IS NO PRE WARNING. IT WILL JUST HAPPEN. PERHAPS THEY ARE MAKING THE BRAKE LINES OUT OF THINNER MATERIAL BECAUSE WE HAVE MANY VEHICLES MUCH OLDER, AND NEVER HAD THIS PROBLEM.

I DROVE APPROX. 30 MILES TO MY DESTINATION WITHOUT ANY TROUBLE. I SPENT ABOUT 2 HOURS THERE THEN STARTED MY 2002 YUKON XL TO HEAD BACK HOME. UPON MOVING THE VEHICLE I REALIZED I HAD VERY LIMITED BREAKING POWER. THE BRAKE PEDAL WENT RIGHT TO THE FLOOR. I DREAD THINKING ABOUT WHAT COULD HAVE HAPPENED IF I WAS ON THE INTERSTATE HEADING HOME. MY MECHANIC SAID THE BRAKE LINE FAILED CAUSING THE REAR BRAKES TO LOSE ALL STOPPING POWER. HE SAID HE HAS SEEN SEVERAL CASES OF THIS SAME PROBLEM ON EARLY 2000'S GMC TRUCKS AND SUV'S. I RESEARCHED THIS ISSUE AND FOUND MANY OF THE SAME COMPLAINTS ONLINE. GMC SHOULD STAND BEHIND THIS AND PAY TO REPAIR THIS OBVIOUSLY DEFECTIVE PART REPLACEMENT. THIS WILL BE AN $800 REPAIR FOR ME AND A BIG DISAPPOINTMENT IN GMC IF THEY DON'T STAND BEHIND THEIR VEHICLES.

WHILE TURNING INTO A MALL PARKING LOT FROM A MAIN STREET, APPLIED BRAKES TO SLOW DOWN INTO THE PARKING LOT FOR A VEHICLE TO PASS IN FRONT OF ME. WITHOUT ANY PRIOR WARNING THE BREAK PEDDLE WENT TO THE FLOOR AND I WAS UNABLE TO STOP EVEN FROM A SLOW SPEED. LUCKLY I WAS ABLE TO DRIVE AROUND THE VEHICLE IN FRONT OF ME BECAUSE THE BREAKS SEEMED TO FAIL ABOUT 95%. I PUMPED THE BREAKS A FEW TIME AND GOT INTO THE CLOSEST PARKING SPACE. THE VEHICLE WAS NOT SAFE TO DRIVE DO TO SUDDEN BREAK FAILURE. THE REPAIR GARAGE CERTIFIED MECHANIC SAID THE BREAK LINE HAD RUSTED THRU AND THE BREAK FLUID WAS RAPIDLY LEAKING. I HAD THE GARAGE REPLACE ALL THE ENTIRE RUSTED BREAK LINES ($646.00) TO BE ABLE TO DRIVE SAFELY AND AVOID ANOTHER SUDDEN BREAK FAILURE DUE TO RUSTED BREAK LINES. OTHERWISE THE CAR HAS BEEN WELL TAKEN CARE FOR AND IN EXCELLENT RUNNING CONDITION. MY MECHANIC SAID THEY HAD REPAIRED SEVERAL GMC VEHICLES WITH THIS IDENTICAL PROBLEM. I BELIEVE GMC HAS SOLD A CAR WITH DEFECTIVE SAFETY PARTS WHICH HAVE WORN PREMATURELY. *TR

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.
