SAFETY ISSUE: WHILE TRAVELING AT HIGHWAY SPEED, THE DRIVERS SEAT RIGHT SIDE BACK SUPPORT BRACKET FAILED. THE ONLY THING KEEPING IT UPRIGHT IS THE LEFT SIDE BRACKET AND SEAT COVERING IN TENSION. IN MY OPINION, A SEAT BRACKET SHOULD NOT FAIL DURING THE LIFE OF THE VEHICLE. I DO NOT PUSH BACK ON MY SEAT, AS I HAVE SEEN OTHERS IN THERE VEHICLES TO CREATE MORE SPACE BEHIND THE STEERING WHEEL. IN FACT, I SIT UP CLOSE TO THE STEERING WHEEL IN AN UPRIGHT POSITION. THE VEHICLE HAS NOT BEEN INVOLVED IN ANY COLLISIONS DURING THE LIFE OF THE VEHICLE.

I OWN A 2001 CHEVY TAHOE. ON OCTOBER 5TH, 2005 I SMELLED SOMETHING BURNING. WHEN I PARKED MY CAR AND PULLED A FILE FOLDER OFF THE SEAT, IT WAS SINGED AND THERE WAS SMOKE COMING FROM THE PASSENGER SEAT. THERE WAS ALSO A BROWN BURN MARK AND THE LEATHER SEAT WAS MELTED. I WENT TO AN APPOINTMENT, MAKING SURE THERE WERE NO INDICATOR LIGHTS ON. TWO HOURS LATER I STARTED THE CAR AND THE SMOKE BEGAN AGAIN, THIS TIME MUCH WORSE. I WENT TO SANDBERG CADILLAC; THEY WERE GOING TO CHARGE ME $110 TO DISCONNECT THE SEAT. THE SERVICE MANAGER HAD GOTTEN INTO THE CAR TO MOVE IT AND SAID THE SEAT WAS STILL SMOLDERING. THEY TORE THE SEAT OUT OF THE CAR AND THERE WAS A FIRE UNDER THE LEATHER. AT THAT TIME THE $110 DISCUSSION WAS DROPPED. I MADE A COMMENT TO THE 5 GENTLEMAN THAT THIS IS UNDER WARRANTY, BUT ISN'T THIS SAFETY ISSUE ALL AGREED. STEVE AND I WENT BACK INSIDE AND HE ARRANGED FOR A LOANER CAR, THROUGH ENTERPRISE. SERGIO SAID THAT HE WOULD BE PUTTING A CALL INTO HIS GM REP AND THAT HE WOULD TALK TO THEM ABOUT COVERING THE EXPENSE OF THE SEAT AND GETTING MY CAR BACK TO THE ORIGINAL CONDITION OF BEFORE THE FIRE. THERE WAS CHEMICAL SMOKE DAMAGE ON THE INTERIOR WHICH DAN; THE TECHNICIAN ASSURED ME THEY HAD A MACHINE THAT WOULD BE ABLE TO GET RID OF THAT SMELL. OCTOBER 6TH, I SPEAK WITH SERGIO AND AFTER SPEAKING WITH THE GM REP HE IS NOT WILLING TO COVER THE DAMAGE AND THE EXTENDED WARRANTY WILL COVER THE HARDWARE, BUT NOT THE ACTUAL SEAT CUSHION OR COVER. AT THIS TIME WE ARE LOOKING AT $1000 WORTH OF DAMAGE NOT INCLUDING THE ANY RENTAL CAR EXPENSE. I AT THAT TIME REQUESTED A CORPORATE NUMBER AND REACHED A BRUCE MITCHELL. I GAVE HIM THE DETAILS OF THE INCIDENT AND HE ASSURED ME THAT SOMEONE WOULD BE IN CONTACT WITH ME BETWEEN 24 AND 48 HOURS. I AM NOW AT THE 48 HOUR MARK AND HAVE HEARD NOTHING. *JB

Status: closed (inferred from source dates) · Service Brakes, Hydraulic; Service Brakes, Hydraulic:foundation Components:hoses, Lines/piping, And Fittings
On January 11, 2011, ODI opened EA11-001 to investigate allegations of premature brake line corrosion failure in model year (MY) 1999 through 2003 General Motors (GM) full-size pickup trucks and sport utility vehicles sold or registered in the following region of the United States that NHTSA has viewed as salt states for investigations of corrosion related issues: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.The subject vehicles represent the first five MY's of GM's GMT800 platform production, of which approximately 2,038,504 vehicles were sold in salt states (the subject vehicles).The GMT800 platform includes the following vehicles:1999-2007 Chevrolet Silverado and GMC Sierra 1500, 2500 and 3500 series pick-up trucks; 2000-2006 Chevrolet Suburban, Chevrolet Tahoe and GMC Yukon sport utility vehicles; and 2002-2006 Cadillac Escalade and Chevrolet Avalanche sport-utility vehicles.General Motors produced a total of approximately 10,427,062 GMT800 vehicles for sales in the United States, including almost 5 million that were sold in salt states.Although there are over 60 different brake pipe routing configuration used in GMT800 vehicles, with the exception of the rear crossover pipes in MY 200x-2007 vehicles that changed from rear disc to drum brakes, all of the vehicles use brake pipes from the same supplier with a common double-wall, brazed steel pipe design with a combination of hot dip Zinc-Aluminum corrosion protection coating and Aluminum paint outer layer known in the industry as AlGal (ASTM-B750). ODI analysis of field data regarding GMT800 vehicles identified a total of 3,645 complaints of brake pipe corrosion failures, including 107 alleging crashes, and 40 injuries.Though only 20% of total GMT800 production, due to age and region the subject vehicles account for a disproportionate share of the failure experience; with 2,702 of the complaints (75%), 88 of the crashes (82%) and 20 of the injuries (50%) reported in those vehicles.Analysis of the complaints showed strong correlations to vehicle age and region.For vehicles with less than 8 years of service, the complaint rates were minimal for all regions.In the salt states the failure rates begin to climb as the vehicles advance in age, particularly in the Northeast corner of the United States.The complaint rates in the salt states go from less than 0.1 incident per thousand vehicles (IPTV) at 7 years in service to over 1.0 IPTV after the 12th year of service for the subject pickup trucks and utility vehicles.Most of the failures reported to ODI occurred in vehicles with more than 10 years in service.ODI?s investigation did not identify any specific defect conditions that were causing or contributing to the brake pipe failures.Nor did the analysis isolate the problem to any subject vehicle sub-populations when analyzed by vehicle type or production range.The investigation found that vehicles experiencing brake pipe corrosion failures were likely to have general patterns of excessive corrosion on the majority of the brake pipe assembly and appear to be occurring due to expected wear out for the brake pipe coating material used in the subject vehicles and the environmental conditions in severe corrosion states.A safety-related defect has not been identified at this time.Accordingly, this investigation is closed.The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist.The agency will monitor t

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.
