I STARTED VEHICLE, DEPRESSED THE BRAKE PEDAL, I THEN PLACED THE SHIFTER INTO REVERSE AND PROCEEDED TO DRIVE WHEN I REALIZED THE VEHICLE WASN'T STOPPING AS USUAL. I THEN PUT THE SHIFTER INTO DRIVE AND PARKED IT . I GOT OUT OF THE VEHICLE AND NOTICED ALOT OF FLUID (ON THE DRIVERS SIDE) ALL OVER THE GROUND. I CALLED A TOW TRUCK TO HAVE IT MOVED TO A MECHANICS LOCATION FOR FURTHER INSPECTION. THE MAIN (CORRODED) BRAKE LINE BURST CAUSING FLUID TO LEAK EVERYWHERE AND CREATING A POTENTIALLY SERIOUS LIFE THREATENING DRIVING HAZARD ( BRAKE FAILURE) HAD I NOT PARKED THE VEHICLE IT WOULD HAVE BEEN A DIFFERENT ENDING....THIS NEEDS TO INVESTIGATED IMMEDIATELY. *TR

UNLIKE MANY OTHERS MY CHEVROLET MECHANIC WARNED ME OF THE CORROSION PROBLEMS THEY FOUND ON MY BRAKE LINES ON MY GMC 2002 YUKON, AND THE NEED TO REPLACE THEM. THIS $1,700 REPAIR IS EXCESSIVE, BUT I COULD NOT CONSIDER RISKING FAILURE. WE TRAVEL ON HIGHWAYS CLOSE TO 1,000 MILES PER MONTH AND OCCASIONALLY TOW A 5,000 POUND BOAT/TRAILER. I TYPICALLY BUY NEW CARS, MAINTAIN THEM WITH THE DEALER AND RUN THEM AS LONG AS I CAN. I HAVE NEVER SEEN OR HEARD OF SUCH A COMPREHENSIVE FAILURE. HAVING ONLY BRIEFLY RESEARCHED THIS ON LINE AND EASILY FINDING HUNDREDS OF REPORTED FAILURES, I CANNOT BELIEVE THAT GMC HAS NOT BEEN HELD ACCOUNTABLE. A FRIEND HAS REPORTED TO US THAT BOTH THEIR SIERRA AND YUKON EXPERIENCED ON ROAD FAILURES. I MAINTAIN MY CARS AS RESPONSIBLY AS I CAN, AT A COST, BUT NOT WANTING ANY HIGHWAY FAILURES. I HATE TO THINK ABOUT THE AGING GMC/CHEVY TRUCK POPULATION THAT IS NOW DRIVING NEXT TO ME. WHY HAS GMC NOT BEEN HELD ACCOUNTABLE. *TR

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

DRIVING FROM TAMPA TO ORLANDO IN MY 2002 GMC YUKON WITH TRAILER IN TOW. BRAKES WENT TO FLOOR WHILE HAD TO USE EMERGENCY BRAKE. I WAS TOW HOME BY AAA NO FLUID IN RESERVOIR FILLED IT UP. SAW FLUID LEAKING UNDER DRIVERS DOOR LOOK WITH FLASHLIGHT AND SAW CLUSTER OF LINES CORRODED LEAKING FROM A ROUND DEVICE AND RUNNING DOWN THE RAIL TOWARD BACK. ABOUT TWO FT. LONG. I THINK THEY ARE THE METAL BRAKE LINES AND THEIR FAILURE SEEMS LIKE A DEFECT IN MATERIAL AS I THINK THEY SHOULD BE MADE OF A HARDER OR MORE LASTING STAINLESS STEEL OR SOMETHING AS BRAKES ARE THE MOST IMPORTANT DEVICE ON A VEHICLE. I NOW FEEL FOR THE SAFETY OF MY FAMILY GMC SAID IMPROPER MAINTENANCE. I THINK GMC SHOULD TAKE CARE OF THEIR FAULTY DEFECTIVE BRAKE LINES BEFORE SOMEONE IS KILLED OR MAYBE THEY HAVE ALREADY. *TR

ABS ACTIVATES DURING SLOW STOPS, INCREASES STOPPING DISTANCE. DEALER PERFORMED RECALL 05V37900 AND PROBLEM PERSISTS. DEALER REPLACED BOTH FRONT SPEED SENSORS AND PROBLEM PERSISTS. I BELIEVE PROBLEM IS CORROSION IN FRONT WHEEL HUBS ON TONE RING. RECALL DOES NOT ADDRESS THAT PART.

MY 2002 GMC YUKON HAS THE PROBLEM THAT WHEN STOPPING AT SLOW SPEEDS THE ABS BRAKES ACTIVATE CAUSING THE CAR TO LURCH FORWARD BEFORE COMING TO A COMPLETE STOP. THIS IS THE THIRD TIME I HAVE EXPERIENCED THIS WITH THIS VEHICLE. THE FIRST TIME WAS JUST BEFORE THE RECALL FOR THIS PROBLEM IN 2005, THE SECOND TIME WAS IN THE SUMMER OF 2007 WHEN IT WAS FIXED UNDER THE RECALL, AND JUST RECENTLY WHEN I HAD TO AGAIN PAY FOR THE REPAIR. EACH TIME IT WAS REPAIRED BY REMOVING AND CLEANING OR REPLACING THE SENSORS. OBVIOUSLY THE REPAIR DONE AS A RESULT OF THE RECALL IS TEMPORARY AT BEST AND THE SAFETY ISSUE OF THE CAR LURCHING FORWARD RETURNS. IN MY CASE IT APPEARS TO RETURN IN ABOUT 2 YEARS. *TR

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.

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.
