2000 Chevrolet Silverado

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

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'S REVIEW OF COMPLAINT DATA RECEIVED SINCE THE CLOSE OF EA04-011 REVEALED NO INDICATION THAT THE INVESTIGATION SHOULD BE RE-OPENED.MORE DETAILS CAN BE FOUND IN THE FEDERAL REGISTER NOTICE ENCLOSED IN THE DP05-009 PUBLIC FILE.ODI RESERVES THE RIGHT TO REOPEN THE INVESTIGATION IN THE FUTURE SHOULD CONDITIONS WARRANT.

IN A LETTER DATED AUGUST 29, 2005, GM NOTIFIED ODI THAT IT WAS RECALLING CERTAIN MODEL YEAR 1999 THROUGH 2002 C/K PICKUP TRUCKS AND SPORT UTILITY VEHICLES TO CORRECT A PROBLEM WITH ANTI-LOCK BRAKE SYSTEM (ABS) WHEEL SPEED SENSOR CORROSION THAT MAY RESULT IN UNWANTED ABS ACTIVATION AND EXTENDED STOPPING DISTANCES DURING LOW-SPEED BRAKING (RECALL 05V-379).GM'S RECALL COVERS APPROXIMATELY 804,000 VEHICLES CURRENTLY REGISTERED IN THE FOLLOWING 14 SALT-BELT STATES:CONNECTICUT, ILLINOIS, INDIANA, MASSACHUSETTS, MAINE, MICHIGAN, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT, AND WEST VIRGINIA.THE RECALL PROCEDURE WILL INVOLVE REMOVING THE SENSOR, CLEANING THE MOUNTING SURFACE, APPLYING A RUST INHIBITOR (ZINC-X) TO THE SURFACE, AND REINSTALLING THE SENSOR.IF NECESSARY, THE SENSOR WILL BE REPLACED.

I WAS HAVING THE EXHAUST CHANGED WHEN I WAS NOTIFIED THAT ONE OF THE CROSS MEMBERS FOR THE FRAME HAD RUSTED COMPLETELY THROUGH AND NEEDED TO BE REPAIRED. IT HAS BEEN REPAIRED, BUT I WAS INFORMED THAT EXCESSIVE RUST IS IN VARIOUS LOCATIONS ON THE REAR OF THE FRAME AND WILL NEED TO BE WATCHED CLOSELY. KEEP IN MIND THAT THESE CROSS MEMBERS SUPPORT THE FUEL TANK AND IF ONE WOULD BREAK, IT LOOKS LIKE IT COULD CASSETTE FUEL TANK TO FALL OFF. THE TRUCK HAS 100,500 MILES ON IT, WHICH IS NOT EXCESSIVE FOR THE YEAR. THE TRUCK SPENT MOST OF ITS LIFE IN MICHIGAN, BUT NOW RESIDES IN ILLINOIS. I HAVE READ SEVERAL FORUMS HAVING THE SAME COMPLAINTS FOR THE 99-2007 MODEL YEAR VEHICLES. THERE ARE SEVERAL HOLES PLACED ON THESE CROSS MEMBERS BY THE MANUFACTURER THAT ALLOW MOISTURE IN, WITH NO PLACE FOR THE MOISTURE TO GO ONCE IT IS PLACE. I AM SURE THERE IS ALSO A LACK OF PROPER PAINT APPLICATION AND EVEN POOR STEEL THAT IS LIKELY CAUSING THE ISSUE. JUST AS TOYOTA HAS DONE, CHEVY SHOULD OFFER A RECALL FOR EXCESSIVE RUST ON THE FRAME. THE TOYOTA TUNDRA RECALL OFFERS A NEW FRAME FOR ANY TUNDRA WITH A RUST HOLE 10MM OR LARGER. WHY ISN'T THE NHTSA INVESTIGATING THIS FURTHER? THIS A SERIOUS SAFETY CONCERN AND ALSO CONSIDERABLY LOWERS THE VALUE OF THE VEHICLE. GM AND CHEVY NEED TO BE HELD ACCOUNTABLE FOR THEIR DECISIONS WHEN DESIGNING AND MANUFACTURING THESE VEHICLES, JUST AS TOYOTA TOOK ACCOUNTABILITY FOR THEIR DECISIONS.

AS I ATTEMPTED TO BRAKE TO A STOP ON DRY PAVEMENT, THE BRAKE PEDAL SUDDENLY STIFFENED,PREVENTING ME FROM USING THE PEDAL TO COME TO A CONTROLLED STOP. FORTUNATELY, I WAS GOING SLOW AT THE TIME AND WAS IN A PARKING LOT, SO WAS ABLE TO STEER AWAY FROM COLLIDING WITH A PARKED CAR.. FROM ALL THAT I READ ,THE ROOT CAUSE OF THIS PROBLEM INVOLVES THE ABS SYSTEM. ABOUT 3 YEARS AGO, I HAD THE BRAKE LINES COMPLETELY REPLACED WITH A BETTER GRADE THAN CAME WITH THE TRUCK. I DID THIS BECAUSE, WHILE THE TRUCK IS GOING ON 15 YEARS, THE MAIN COMPONENTS APPEAR TO HAVE SEVERAL MORE YEARS. BUT NOT WITH THIS SORT OF FUNDAMENTAL SAFETY ISSUE. I'M ANGRY THAT GM HAS NOT HAD TO RECALL MY TRUCK FOR THIS OBVIOUS SAFETY FLAW IN THE BRAKE SYSTEM.

THE ABS BRAKING SYSTEM GOES STIFF AT LOW SPEEDS. I HAVE TO JAM ON THE BRAKES EXTREMELY HARD IN ORDER FOR THEM TO STOP, THE BRAKES EVENTUALLY WILL STOP AFTER A 3 TO FIVE MORE FEET.THE ABS BRAKING SYSTEM IS EXTREMELY DANGEROUS AND SERVES NO PURPOSE.THE VEHICLE WORKS BETTER AFTER DISABLING THE ABS BRAKE SYSTEM.PLEASE RECALL ALL CHEVY SILVERADOS AND TAHOES DUE TO ABS BRAKING SYSTEM ISSUES.
