I AM WRITING IN REGARDS TO MY ANTI LOCK BAKING SYSTEM (ABS) AND MY STEERING COLUMN. I WAS NEARLY INVOLVED IN AN AUTO ACCIDENT ON DRY PAVEMENT WHEN MY ABS SYSTEM ENGAGED AND THEN DIS-ENGAGED AT A SPEED OF LESS THAN 10 MPH. WHEN STEERING TO THE RIGHT TO AVOID THE ACCIDENT, MY STEERING COLUMN HAD A STRANGE VIBRATION/LOUD HUMMING NOISE. MY ANTILOCK BRAKES ENGAGED WHILE I WAS SLOWING TO SWERVE TO MISS THE ONCOMING VEHICLE AND THEN MY ABS STOPPED WORKING AND MY ABS WARNING LIGHT ALONG WITH MY PARKING BRAKE (P) WARNING LIGHT CAME ON. NOW, SINCE THAT DAY (2 DAYS AGO), MY STEERING COLUMN STILL MAKES NOISES WHEN I TURN TO THE RIGHT AND MY ABS SYSTEM CONTINUES TO ENGAGE AT SLOW SPEEDS WHEN STOPPING EVEN ON DRY PAVEMENT. I HAVE BEEN TOLD BY A GM DEALERSHIP THAT THE TWO ISSUES THAT I AM EXPERIENCING ARE NOT ON A RECALL LIST BUT ARE COMMON PROBLEMS WITH MY VEHICLE. THEY FURTHER ADVISED THAT SINCE MY VEHICLE IS NO LONGER UNDER WARRANTY, I WOULD HAVE TO PAY FOR THESE MALFUNCTIONS. I WAS TOLD BY AN INDEPENDENT MECHANIC THAT THE ABOVE ISSUES ARE SAFETY ISSUES AND GM IS AWARE OF THE PROBLEMS. WITH THE ABOVE BEING SAID, I FEEL THAT MY ISSUES WITH THE ABS SYSTEM AND THE STEERING COLUMN ARE SAFETY ISSUES AND GM SHOULD BE ADDRESSING THESE ISSUES BEFORE SOMEONE IS SERIOUSLY INJURED OR KILLED. I NEED TO GET THESE ISSUES CORRECTED ON MY VEHICLE, HOWEVER, I DO NOT FEEL THAT I SHOULD BE LIABLE FOR THESE REPAIRS WHEN GM IS AWARE OF THE ISSUES AND NOTHING HAS BEEN DONE TO REMEDY THE PROBLEM. *TR

2003 CHEVY SILVERADO ANTI-LOCK BRAKES REPEATED CAUSE FAILURE TO STOP, ESPECIALLY ON SLIPPERY SURFACES. THE ALGORITHM DOES NOT WORK. WHILE DRIVING / COASTING AT 25 MPH, A CAR MADE A SUDDEN LANE CHANGE IN FRONT OF ME. I APPLIED THE BRAKES ON A SNOW COVERED ROAD AND THE ANTI-LOCK BRAKES ACTIVATED, CAUSING ME TO ROLL MUCH MORE RAPIDLY TOWARD THE BACK OF THE CAR. I SWERVED INTO A PARKING LOT OPENING, BUT THE REAR DRIVER SIDE SCRAPED A SMALL ROADSIDE TREE. THE ANTI-LOCK BRAKES ALSO ACTIVATE WHEN I APPLY THE BRAKES WHILE DRIVING OVER ROUGH ROADS. I HAVE FREQUENTLY ROLLED INTO INTERSECTIONS WHEN THIS OCCURS. IT'S THE WORST ON SLIPPERY ROADS. I CONDUCTED SEVERAL TESTS BY DRIVING A FIXED SPEED AND ATTEMPTING TO STOP IN AS SHORT A DISTANCE AS POSSIBLE ON A SNOW COVERED SLIPPERY ROAD. IF I APPLY BRAKES UP TO THE POINT WHERE THE WHEELS WANT TO LOCK, BUT I DON'T PRESS HARD ENOUGH TO ACTIVATE THE ANTI-LOCK PULSATION, I CAN STOP IN THE SHORTEST DISTANCE. IF THE ANTI-LOCK BRAKES PULSE, I ROLL MUCH FURTHER. IF I LET OFF THE BRAKES A LITTLE DURING THE PULSATION, THE TRUCK STILL STOPS IN A SHORTER DISTANCE. THIS FLAW IS NOT AS NOTICEABLE ON DRY PAVEMENT. WHEN I NOTIFIED THE DEALER, THEY TOLD ME THAT'S THE WAY THEY ARE, AND THERE WAS NO RECALL, ETC. I HOPE SOMEONE ISSUES A RECALL BEFORE SERIOUS INJURY OR DEATH OCCURS. THERE'S A GOOD CHANCE I WILL DISABLE THE ANTI-LOCK FUNCTIONALITY, AT LEAST DURING WINTER DRIVING. THE ANTI-LOCK BRAKES ON OTHER SIMILAR VEHICLES SUFFER THE SAME CONDITIONS FROM MY INVESTIGATION. THE TRUCK WOULD BE SAFER WITHOUT THIS MALFUNCTIONING SYSTEM. *TR

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
