I OWN 2002 CHEVROLET AVALANCHE 1500 THAT WILL NOT PASS INSPECTION IN TEXAS DUE TO THE FAILURE OF MY PARKING BRAKE TO KEEP THE VEHICLE FROM MOVING AFTER THE PARKING BRAKE HAS BEEN APPLIED, AND THE VEHICLE PUT INTO DRIVE. I UNDERSTAND THAT A RECALL HAS BEEN ISSUED FOR VEHICLES WITH MANUAL TRANSMISSIONS THAT ARE EQUIPPED WITH THE SAME TYPE OF PARKING BRAKE THAT MY VEHICLE HAS. I READ FEDERAL NOTICE DP05-009 OUTLINING A RESPONSE FROM A COMPLAINT REGARDING THE PARKING BRAKE FAILURE THAT WAS DUE TO A FAULTY RETAINING PIN THAT GM HAS NOW CORRECTED. THE RESPONSE STATED THAT SINCE AUTOMATIC TRANSMISSIONS HAD PARKING PAWLS, A RECALL WAS NOT WARRANTED. IF THE STATE OF TEXAS CONSIDERS THE FAILURE OF THE PARKING BRAKE TO BE A SAFETY HAZARD IN AUTOMATIC TRANSMISSIONS, WHY DOES THE NHTSA DEEM THAT IT IS NOT A DEFECT. *JB

CLUNKING IN HEARD UNDER HOOD AND FELT IN THE STEERING COLUMN. HAVE HAD THAT FOR 2 YEARS AND NOW FINALLY SAW OTHER AVALANCHE AND CHEVROLET OWNERS WITH THE SAME PROBLEM, AND PERSONAL MECHANIC EVEN REFERENCED THE PROBLEM TO A TSB FOR MY VIN. DEALER PLAYS IT OFF THAT THEY HAVE TO CHARGE FOR INSPECTION BY MECHANIC AND THEY WON'T REPLACE IT BECAUSE ITS PAST WARRANTY. (BILL HEARD CHEVROLET). NOTHING HAS DONE TO FIX IT, UNSURE IF ANY MECHANICAL FAILURE WILL RESULT FROM IT. INVOLVING THE STEERING COLUMN MUST HAVE SOME POSSIBLE ISSUE. *JB

BRAKES WORK SOMETIMES, HALF BRAKES,( WERE YOU HAVE TO PULL THE EMERGENCY BRAKE TO STOP), OR BRAKES GO ON BY THEMSELVES WERE YOU HAVE TO PULL OVER AND STOP AND WAIT OR COOL YOUR BREAKS UNTIL THEY COOL DOWN.( BECAUSE THE BREAKS ARE SMOKING. )PROBLEM HAS BEEN GOING ON FOR 7 MONTHS. 2002 AVALANCHE. THE VEHICLE HAS BEEN IN THE DEALERS 7 TIMES AND THE LAST TIME ON 05/08/06 BECAUSE I ALMOST HIT A CHILD. THEY REPLACED MY BRAKE LINES BUT BRAKES STILL LOCK UP AND GO ON BY THEMSELVES, WHEN YOU STOP QUICKLY. GAVE THE DEALER THE PAPER WORK ON SALT AFFECTING THE ANTI- LOCK SENSORS RECALL SINCE I LIVE IN FLORIDA ON 05/08/06 AND TOLD ME IN DID NOT APPLY. MY WIFE'S 05 EQUINOX WENT IN FOR THE EXACT SAME PROBLEMS ON 05/12/06 WITH NO BRAKES AT ALL EXCEPT FOR THE EMERGENCY BRAKE AND THEY WANT TO REPLACE HER MASTER CYLINDER. I TOLD THE DEALER ABOUT THE RECALL IN THE NORTHERN STATES AND PROVIDED THEM WITH THE RECALL PAPERWORK AND WAS BLOWN OFF!. MY TRUCK CAME BACK TODAY 05-12-06 WITH THE EXACT SAME PROBLEMS AFTER BEING FIX BY THE DEALER. *NM

I RECENTLY PURCHASED A USED 2002 CHEVROLET AVALANCHE 2500HD 4X4 WITH A 8.1 LITRE ENGINE. THE VEHICLE HAS APPROXIMATELY 51,000 MILES ON IT. THE FIRST PROBLEM I NOTICED WAS THAT THE ENGINE WOULD CRANK, BUT IT WOULD NOT START IMMEDIATELY. THE NEXT PROBLEM I EXPERIENCED WAS THAT THE ENGINE SHUT OFF WHILE I WAS DRIVING IT. THIS RESULTED IN LOSS OF POWER STEERING AND POWER BRAKES, BUT MORE IMPORTANTLY, I WAS NOT ABLE TO MAINTAIN THE POSTED 55 MPH LIMIT, AND I HAD TO DODGE TRAFFIC WHILE TRYING TO STEER MY "DEAD" VEHICLE ONTO THE SHOULDER. THE VEHICLE DID RESTART AND I WAS ABLE TO RESUME AS BEFORE. THIS HAS HAPPENED TO ME AT LEAST 4 TIMES. THUS FAR AFTER 3 TRIPS TO THE DEALER, THEY HAVE NOT BEEN ABLE TO REPEAT, DIAGNOSE, OR REPAIR THIS PROBLEM. *JB

MY VEHICLE (A 2002 CHEVY AVALANCHE) WAS INVOLVED IN A TOTAL LOSS COLLISION ON JANUARY 18, 2006. THE COLLISION WAS A FULL FRONTAL CRASH WHICH CAVED IN THE ENTIRE FRONT END OF THE AVALANCHE. THE AIR BAGS DID NOT DEPLOY, AND THE DRIVER OF THE VEHICLE WAS THROWN OUT OF HIS SEAT BELT DUE TO THE FORCE OF THE IMPACT. THE DRIVER ENDED UP IN THE PASSENGER SEAT OF THE VEHICLE. IT IS MY BELIEF THAT THE AIR BAGS MALFUNCTIONED. THE CRITERIA FOR AIR BAG DEPLOYMENT WERE MET. THERE WAS A DECELERATION RATE FROM APPROX. 55 MPH TO A COMPLETE STOP. THE AIR BAG SENSOR WAS HIT (AS SEEN FROM THE EXAMINATION OF THE VEHICLE UPON ARRIVAL TO THE BODY SHOP). THE COLLISION WAS IN THE MIDDLE FRONT OF THE VEHICLE. GENERAL MOTORS DID AN INSPECTION OF THE VEHICLE, HOWEVER, I WAS NOT PLEASED WITH THEIR CONCLUSION. THEY SAID THAT THE AIR BAGS DID NOT MALFUNCTION. THEY CLAIMED THAT THE VEHICLE "ABSORBED" THE IMPACT, WHICH CAUSED THE AIR BAGS NOT TO DEPLOY. I BELIEVE THAT THIS IS A HUGE SAFETY ISSUE AND IT SHOULD BE INVESTIGATED BY SOMEONE OTHER THAN THE MANUFACTURER, WHO, IN MY OPINION, WAS BIASED IN HIS REVIEW OF THE INCIDENT. *NM

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.

Status: closed (inferred from source dates) · Vehicle Speed Control:linkages
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.
