I WAS DRIVING ALONG AND FELT A DRAGGING SENSATION AND SCRAPING NOISE. I PULLED THE TRUCK OVER, LOOKED UNDERNEATH EXPECTING TO SEE THE MUFFLER DRAGGING. I WAS SOMEWHAT SURPRISED TO SEE THE GAS TANK RESTING ON THE STREET. THERE WAS A SMALL AMOUNT OF GASOLINE LEAKING ONTO THE STREET. I CALLED AAA TO COME TOW THE CAR. THEY SAID I NEEDED TO CALL THE FIRE DEPT., WHICH I DID [XXX] SOON THERE WERE 2 FIRE TRUCKS AND A HAZMAT VEHICLE. THEY PROCEEDED TO CALL THE MARYLAND DEPARTMENT OF THE ENVIRONMENT, AND 2 OF THEIR TRUCKS ARRIVED. THE FIRE DEPARTMENT CUT THE REMAINING STRAP AND REMOVED THE TANK. THE MDE PUMPED THE REMAINING FUEL INTO A METAL BARREL. IN LIGHT OF FORD'S RECALL ON 1.1 MILLION PICK-UP TRUCKS, I THOUGHT IT IMPORTANT TO REGISTER THIS REPORT AS IT IS POSSIBLE THAT GMC MIGHT BE USING THE SAME STRAPS TO SUPPORT THE GAS TANKS. I DO NOT HAVE VIN # AS THE VEHICLE WAS TOWED TO S & L AUTO [XXX] *JS INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I OWN A 2000 GMC SIERRA 2500 4WD. I BOUGHT THIS TRUCK NEW IN JUNE OF 2000. IN THE PAST YEAR, THE CORROSION ISSUES ARE BECOMING OVERWHELMING. YESTERDAY, A BRAKE LINE BLEW OUT WHILE DRIVING. THE BRAKE PEDAL WENT TO THE FLOOR AS I APPROACHED A STOP SIGN AT AN INTERSECTION WITH A STATE HIGHWAY. LUCKILY, I GOT STOPPED AS I WAS ONLY GOING 25 MPH. I BABIED IT TO A LOCAL GARAGE 1/4 MILE AWAY, AND FOUND BRAKE FLUID DRIPPING OUT BELOW THE FUEL TANK AREA. AFTER LOOKING UNDERNEATH, THE MECHANIC NOTICED THAT MOST OF THE BRAKE LINES WILL NEED REPLACED BECAUSE OF RUST. GOES ALONG WITH THE CORROSION ISSUE UNDER THE WHOLE TRUCK. I'VE ALREADY REPLACED THE REAR SPRING SHACKLES ON BOTH SIDES, AS ONE HAD RUSTED AND BROKE IN HALF WHILE DRIVING. THIS CAUSED THE LEAF SPRING TO SLAM UP AGAINST UNDERSIDE OF THE BED, WHICH DENTED AND CRACKED THE PAINT IN THE BED. I RESTORE VEHICLES FOR A LIVING, AND I'VE SEEN CARS FROM THE 1940'S THAT DON'T HAVE THIS MUCH RUST ON THE UNDERSIDE. COME ON GM!! IT'S GREAT THAT THE BODY LOOKS LIKE NEW AND THE ENGINE RUNS GREAT, BUT IT DOESN'T DO ANY GOOD WHEN THE FRAME ROTS OUT FROM UNDERNEATH!! AND NOW THE BRAKE LINES---GLAD I WASN'T GOING 60 MPH WITH A LOADED TRAILER WHEN IT BLEW!! *JB

WHILE PULLING A SMALL ENCLOSED TRAILER AND GOING DOWN A HILL I EXPERIENCED A COMPLETE BRAKE FAILURE. I HAD ABSOLUTELY NOTHING FOR BRAKES. I ENDED UP GOING THROUGH A REDLIGHT AND MISSED ANY VEHICLES IN THE INTERSECTION, STARTED TO DOWNSHIFT TO SLOW MY SPEED. CROSSED OVER AN INTERSECTION FOR A BIKE TRAIL WITH NOONE IN THE WAY. THEN HAD TO MAKE A HARD RIGHT TURN TO GO UNDER A TRAIN TRESSEL NARROWLY MISSING AN ON COMING CAR. WHEN I FINALLY GOT THE VEHICLE STOPPED I HAD DROPPED VERTICALLY 80 + FEET IN THE MATTER OF LESS THAN A HALF MILE. ON THE GROUND WAS A PUDDLE OF BRAKE FLUID FROMTHE CORRODED BRAKE LINES THAT HAD BURST RENDERING MY TRUCK IN TO AN UNSTOPPABLE DOWNHILL BOBSLED. THE WEATHER CONDITIONS WE SUNNY AND 80 DEGREES. LUCKILY NOONE WAS IN MY WAY AND I WAS ABLE TO MISS ANY OBJECTS AND STEER THE TRUCK TO A SAFE SPOT. I AM ALSO THANKFUL THAT NEITHER OF MY KIDS WERE IN THE TRUCK WITH ME AT THE TIME OF THIS INCIDENT. I FEEL THAT THERE SHOULD BE SOME ACCOUNTABILITY IN TO WHAT A MANUFACTURE USES FOR VITAL SAFETY ITEMS IN A VEHICLE. BRAKES LINES SHOULD BE A PART THAT SHOULD OUTLAST THE USEFULNESS OF THE VEHICLE . NOT SOMETHING THAT SHOULD BE A POSSIBLE FAILURE POINT ANY GIVEN TIME. THIS IS A MATTER OF PUBLIC SAFETY HOW MANY MORE PEOPLE HAVE TO DIE OR GET INJURED DUE TO A COST SAVINGS OF USING REGULAR STEEL LINES ON THE ONE PART THAT MAKES YOU VEHICLE STOP? I HAVE HEARD OF PLENTY OF PEOPLE WITH MULTIPLE VEHICLE TYPES WHO HAVE HAD THEIR BRAKE LINES FAIL. THIS IS JUST UNACCEPTABLE THANK YOU FOR ANYTHING THAT YOU MAY TRY TO DO ON THIS ISSUE . *TR

WHILE POSITIONING MY GMC SIERRA PICKUP TO BACKUP MY UTILITY TRAILER THE BRAKES COMPLETELY FAILED. THE BRAKE PEDAL FELL COMPLETELY TO THE FLOOR WITH NO STOPPING CAPABILITY. BRAKE FLUID WAS FOUND SQUIRTING OUT OF A BURST OPEN METAL BRAKE LINE LOCATED ON A FRAME MEMBER UNDER THE AREA OF THE RADIATOR. I TRACED THE LINE FROM THE FRONT RIGHT WHEEL TO THE BRAKE CONTROL MODULE LOCATED UNDER THE DRIVERS SEAT. THE LOCATION OF THE LEAK WAS IN A STRAIGHT SECTION OF THE LINE WITH NO CLAMPS IN THE VICINITY. ALL THE BRAKE LINES APPEAR TO BE COMPLETELY RUSTED. THE TRUCK IS NOW OBVIOUSLY UNDRIVABLE. I HAD JUST FINISHED A 20 MILE ROAD TRIP AND ARRIVED HOME WHEN THE BRAKES FAILED. I WAS ALWAYS UNDER THE IMPRESSION THAT THE BRAKE SYSTEM WAS COMPLETELY SEPARATED, FRONT FROM THE REAR. I DON'T UNDERSTAND HOW ONE BURST FRONT BRAKE LINE CAN CAUSE COMPLETE BRAKE FAILURE. I AM LOOKING FOR DIRECTION. *TR

Official recalls
8Mar 8, 2006
CERTAIN PICKUP TRUCKS HAVE GALVANIZED-BRAIDED-STEEL TAILGATE SUPPORT CABLES USED TO SUPPORT THE TAILGATE IN THE FULL OPEN (HORIZONTAL) POSITION. OVER TIME THESE CABLES CAN CORRODE AND FRACTURE WHEN LOADS ARE APPLIED TO THEM.
Consequence & remedy
Consequence: IF ONE CABLE FRACTURES, THE REMAINING CABLE MAY RETAIN THE TAILGATE IN A HORIZONTAL POSITION. IF BOTH CABLES FRACTURE, THE TAILGATE WOULD DROP AND STRIKE THE TOP SURFACE OF THE REAR BUMPER. IF ANYONE IS SITTING OR STANDING ON THE HORIZONTAL SURFACE OF THE TAILGATE WHEN BOTH CABLES FRACTURED, THEY COULD FALL AND BE INJURED. ON VEHICLES WITHOUT A BUMPER, THE TAILGATE MAY DROP TO A LOWER POSITION.
Remedy: DEALERS WILL REPLACE THE GALVANIZED SUPPORT CABLES WITH STAINLESS STEEL SUPPORT CABLES. IN ADDITION, DEALERS ARE TO INSPECT THE TAILGATE HINGE AND REPLACE IT, IF NECESSARY. THE RECALL IS EXPECTED TO BEGIN DURING APRIL 2006. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438 OR GMC AT 1-866-996-9463.
Aug 29, 2005
CERTAIN PICKUP TRUCKS AND SPORT UTILITY VEHICLES MAY EXPERIENCE UNWANTED ANTILOCK BRAKE SYSTEM (ABS) ACTIVATION. THIS CONDITION IS MORE LIKELY TO OCCUR IN ENVIRONMENTALLY CORROSIVE AREAS. THIS RECALL WILL BE LAUNCHED IN THE "SALT BELT" STATES OF CONNECTICUT, DELAWARE, ILLINOIS, INDIANA, IOWA, MARYLAND, MASSACHUSETTS, MAINE, MICHIGAN, MINNESOTA, MISSOURI, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT, WEST VIRGINIA, WISCONSIN AND THE DISTRICT OF COLUMBIA ONLY.
Consequence & remedy
Consequence: THIS CAN CAUSE INCREASED STOPPING DISTANCES DURING LOW-SPEED BRAKE APPLICATIONS, WHICH COULD RESULT IN A CRASH.
Remedy: DEALERS ARE TO REMOVE THE WHEEL SPEED SENSOR AND THOROUGHLY CLEAN THE WHEEL SPEED SENSOR MOUNTING SURFACE ON THE BEARING, APPLY RUST INHIBITOR TO THE CLEANED SURFACE, GREASE THE MOUNTING SURFACE, REINSTALL THE WHEEL SPEED SENSOR, AND CHECK THE PEAK-TO-PEAK OUTPUT VOLTAGE TO ENSURE THE WHEEL SPEED SIGNAL IS WITHIN SPECIFICATIONS. THE RECALL BEGAN SEPTEMBER 22, 2005. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438 OR GMC AT 1-866-996-9463.
Apr 22, 2005
ON CERTAIN PICKUP TRUCKS EQUIPPED WITH MANUAL TRANSMISSIONS AND BUILT WITH EITHER PBR PARKING BRAKE SYSTEMS OR TRW PARKING BRAKE SYSTEMS, THE PARKING BRAKE FRICTION LININGS MAY WEAR TO AN EXTENT WHERE THE PARKING BRAKE CAN BECOME INEFFECTIVE IN IMMOBILIZING A PARKED VEHICLE.
Consequence & remedy
Consequence: IF THE PARKING BRAKE DOES NOT HOLD, UNINTENDED VEHICLE MOVEMENT COULD OCCUR, WHICH COULD RESULT IN A CRASH.
Remedy: DEALERS WILL INSTALL A LOW-FORCE SPRING CLIP RETAINER FOR VEHICLES EQUIPPED WITH A PBR PARKING BRAKE SYSTEM. ON VEHICLES EQUIPPED WITH THE TRW PARKING BRAKE SYSTEM, DEALERS WILL INSTALL A REDESIGNED PARKING BRAKE CABLE ASSEMBLY. THE RECALL BEGAN ON JULY 29, 2005. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438 OR GMC AT 1-866-996-9463.

SOME PICKUP TRUCKS, VANS, AND SPORT UTILITY VEHICLES EQUIPPED WITH A HYDRAULIC PUMP DRIVESHAFT THAT CAN FRACTURE, RESULTING IN IMMEDIATE LOSS OF HYDRAULIC POWER STEERING ASSIST. ON CERTAIN VEHICLES EQUIPPED WITH HYDRO-BOOST POWER BRAKES, THE SAME CONDITION CAN RESULT IN LOSS OF POWER ASSIST FOR BRAKING AFTER THE RESERVE PRESSURE IS DEPLETED.
Consequence & remedy
Consequence: AN INOPERATIVE PUMP CAN CAUSE INCREASED STEERING EFFORT, AND IN HYDRO-BOOST EQUIPPED VEHICLES ALSO INCREASED BRAKING EFFORT, BUT DOES NOT COMPLETELY ELIMINATE THE ABILITY TO STEER OR SLOW THE VEHICLE.
Remedy: DEALERS WILL REPLACE THE HYDRAULIC PUMP. THE CAMPAIGN BEGAN ON FEBRUARY 14, 2005. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438 OR GMC AT 1-866-996-9463.
Mar 17, 2004
ON CERTAIN PICKUP TRUCKS AND SPORT UTILITY VEHICLES, THE GALVANIZED STEEL TAILGATE SUPPORT CABLES THAT RETAIN THE TAILGATE IN THE FULL OPEN (HORIZONTAL) POSITION MAY CORRODE, WEAKEN, AND EVENTUALLY FRACTURE. IF BOTH CABLES FRACTURED, THE TAILGATE WOULD SUDDENLY DROP AND STRIKE THE TOP SURFACE OF THE REAR BUMPER.
Consequence & remedy
Consequence: ANYONE SITTING OR STANDING ON THE HORIZONTAL SURFACE OF THE TAILGATE WHEN BOTH CABLES FRACTURED COULD BE INJURED BY FALLING FROM THE TAILGATE. ON VEHICLES THAT HAVE HAD THE BUMPER REMOVED, THE TAILGATE MAY DROP EVEN LOWER. ADDITIONALLY, IF THERE IS CARGO ON THE TAILGATE THE CARGO MAY FALL OFF IF THE SUPPORT CABLES FRACTURE.
Remedy: DEALERS WILL REPLACE THE CABLES. INTERIM OWNER NOTIFICATION BEGAN ON APRIL 7, 20004. THE RECALL BEGAN ON SEPTEMBER 24, 2004, WHEN REPLACEMENT PARTS WERE AVAILABLE, AND WILL CONTINUE THROUGH OCTOBER 29, 2004. OWNERS SHOULD CONTACT CADILLAC AT 1-866-982-2339, CHEVROLET AT 1-800-630-2438 OR GMC AT 1-866-996-9463, OR VISIT WWW.MYGMLINK.COM, AND ENTER YOUR VEHICLE IDENTIFICATION NUMBER.

ON CERTAIN PICKUP AND UTILITY TRUCKS, SOME OF THESE VEHICLES HAVE AN AIR BAG SENSING DIAGNOSTIC MODULE (SDM) WHICH CONTAINS AN ANOMALY THAT COULD RESULT IN THE DRIVER AND PASSENGER'S AIR BAG FAILING TO DEPLOY DURING CERTAIN FRONTAL CRASHES.
Consequence & remedy
Consequence: IN A VEHICLE CRASH, FRONT SEAT OCCUPANTS MAY RECEIVE MORE SEVERE INJURIES.
Remedy: DEALERS WILL RECALIBRATE THE SDM ON THE AFFECTED VEHICLES. OWNER NOTIFICATION BEGAN AUGUST 28, 2002. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT CHEVROLET AT 1-800-222-1020 OR GMC AT 1-800-462-8782.
Oct 30, 2000
VEHICLE DESCRIPTION: LIGHT DUTY PICKUP TRUCKS AND SPORT UTILITY VEHICLES. SOME OF THESE VEHICLES HAVE A CLEARANCE CONDITION BETWEEN THE FRONT RIGHT-HAND BRAKE PIPE AND THE BODY CROSS SILL THAT COULD DECREASE TO THE POINT OF ALLOWING CONTACT DURING THE LIFE OF THE VEHICLE. IF CONTACT OCCURS AND THE BRAKE PIPE BECOMES DAMAGED, IN HALF OF THE BRAKE SYSTEM THERE CAN BE A LOSS OF BRAKE FLUID AND PRESSURE. THE BRAKE WARNING LAMP WILL BE ACTIVATED WHEN THE BRAKE FLUID LEVEL REACHES THE INDICATOR LIMIT.
Consequence & remedy
Consequence: DURING BRAKING, THE PEDAL WILL BE LOWER THAN NORMAL AND STOPPING DISTANCES WILL BE LONGER. IF THIS OCCURS WHEN STOPPING DISTANCE IS LIMITED, A CRASH COULD OCCUR.
Remedy: DEALERS WILL INSPECT THE FRONT RIGHT-HAND BRAKE PIPE FOR WEAR. IF THERE ARE SIGNS OF WEAR, THIS SECTION OF THE BRAKE PIPE WILL BE REPLACED WITH A NEW DESIGNED BRAKE PIPE SECTION. IF THERE ARE NOT SIGNS OF WEAR ON THE BRAKE PIPE, THE DEALER WILL INSTALL A SPACER CLIP TO ENSURE SUFFICIENT CLEARANCE BETWEEN THE BRAKE PIPE AND THE BODY CROSS SILL.
Feb 28, 2000
VEHICLE DESCRIPTION: LIGHT DUTY PICKUP TRUCKS EQUIPPED WITH 4-WHEEL DISC BRAKES. SOME OF THESE VEHICLES HAVE AN ANTILOCK BRAKE SYSTEM (ABS) MOTOR CONTAINING AN OUT-OF-SPECIFICATION SPRING CLIP. THIS CLIP COULD ALLOW THE MOTOR BEARING TO BECOME MISALIGNED. IF MISALIGNMENT OCCURS, EVENTUALLY THE ABS WOULD BE NON-FUNCTIONAL.
Consequence & remedy
Consequence: THE BASE BRAKES WOULD REMAIN FULLY FUNCTIONAL, BUT THE DYNAMIC REAR PROPORTIONING (DRP) SYSTEM, WHICH OPTIMIZES FRONT TO REAR BRAKE BALANCE, WOULD BECOME INOPERATIVE.
Remedy: DEALERS WILL REPLACE THE BRAKE PRESSURE MODULE VALVE ASSEMBLY.

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.
