TL* THE CONTACT OWNS A 2003 CHEVROLET AVALANCHE 1500. WHILE DRIVING 60 MPH, THE VEHICLE FAILED TO ACCELERATE. THE INSTRUMENT PANEL GAUGES FLUCTUATED INDEPENDENTLY AND SEVERAL WARNING INDICATORS ILLUMINATED. THE VEHICLE ALSO STALLED. THE CONTACT WAS ABLE TO RESTART THE VEHICLE, BUT THE FAILURE RECURRED MULTIPLE TIMES. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO DIAGNOSED THAT THE VEHICLE HAD ELECTRICAL ISSUES. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE ISSUE. THE APPROXIMATE FAILURE MILEAGE WAS 230,000.

I WAS DRIVING APPROXIMATELY 15 TO 20 MPH DOWN A HILL THAT WAS CURVY AND ALL OF A SUDDEN MY TRUCK COMPLETELY SHUTS OFF AS I WAS DRIVING DOWN THE HILL AND ALMOST WENT INTO A DITCH BECAUSE THE TRUCK JUST SHUT OFF WHILE IN DRIVE AND LUCKILY I WAS QUICK ENOUGH TO PUT IT IN NEUTRAL SO I COULD STEER IT AWAY FROM THE DITCH AND I TURNED THE IGNITION OVER AND LUCKILY IT TURNED ON WHILE IN NEUTRAL OTHERWISE I WOULD OF CRASHED INTO THE DITCH. THEN IT SHUT OFF AGAIN ABOUT 30 SECONDS AFTER AND LUCKILY I WAS ABLE TO PUT IT IN NEUTRAL AGAIN SO I COULD STEER AND COAST DOWN THE HILL BECAUSE IT WOULDN'T START UP THE SECOND TIME WHEN IT ALL SHUT OFF. I WAS STRANDED AT THE BOTTOM OF THE HILL NEAR A LIGHT SO I TRIED TO START IT AGAIN AND IT WOULD KEEP TRYING TO TURN OVER BUT WOULDN'T START AGAIN. I WAS STRANDED IN THE MIDDLE OF THE ROAD AND HAD TO CALL AAA TO TOW MY AVALANCHE TO MY HOUSE. THIS COULD OF KILLED ME IF I WASN'T QUICK ENOUGH TO FIGURE OUT TO PUT IT IN NEUTRAL TO BE ABLE TO STEER. THERE SHOULD BE A RECALL ON WHATEVER MADE THIS HAPPEN AND I STILL DON'T KNOW WHAT IS WRONG WITH IT BECAUSE IT HAPPENED LATE LAST NIGHT AND I WAS LOOKING FOR RECALLS AND IT DOESN'T SHOW ANYTHING ON THIS. *TR

IN LIGHT OF THE RECENT INFORMATION CONCERNING GM'S INTENTIONAL WITHHOLDING OF PROBLEMS WITH THE IGNITION SWITCH IN CERTAIN GM VEHICLES, I FEEL COMPELLED TO SHARE MY STORY.

IN LIGHT OF THE RECENT INFORMATION CONCERNING GM'S INTENTIONAL WITHHOLDING OF PROBLEMS WITH THE IGNITION SWITCH IN CERTAIN GM VEHICLES, I FEEL COMPELLED TO SHARE MY STORY. I DO SEE OTHER COMPLAINTS FILED HERE CONCERNING THE SAME ISSUE. IN OCTOBER 2003, I PURCHASED A NEW 2003 CHEVROLET AVALANCHE 1500. THE VEHICLE HAD 5,500 DEMO MILES ON THE ODOMETER. I DROVE MANY MILES FOR WORK AND FOR TRANSPORTING HOCKEY KIDS TO PRACTICE, GAMES, TOURNAMENTS, ETC. IN DECEMBER 2006 I ALREADY HAD 80,000+ MILES ON THE VEHICLE AND THE SPEEDOMETER, GAS GAUGE (CAUSING ME TO RUN OUT OF GAS IN THE MIDDLE OF THE NIGHT!), OIL GAUGE, BATTERY VOLTMETER, RPMS, WHICH ARE ALL COMPONENTS OF AN ELECTRICAL CLUSTER BEGAN FAILING. I CONTACTED MY GM DEALER AND WAS TOLD THAT A 'SILENT RECALL' HAD BEEN ISSUED TO DEALERS STATING THAT IF A VEHICLE WITH LESS THAN 3 YEARS AND UNDER 70,000 MILES WAS BROUGHT IN, THE DEALER SHOULD FIX THE ITEM AS A WARRANTY REPAIR. SINCE MY VEHICLE WAS 2 MOS OVER THE 3 YR AND OVER THE 70,000 MILES, I WAS DENIED A WARRANTY REPAIR AND QUOTED $700.00 TO FIX THE PART. SINCE THAT DATE, MY SON'S CHEVROLET VEHICLE HAD THE SAME PROBLEM! AND, IN 2009 A FRIEND'S BRAND NEW DENALI WITH LESS THAN 10,000 MILES HAD THE SAME PROBLEM. I HAVE NEVER FIXED THE PROBLEM DUE TO COST AND DISAGREEMENT WITH GM. I WROTE THE CORPORATE OFFICE AND GOT NOWHERE. I DON'T SEE HOW A SAFETY ISSUE LIKE THIS CAN BE ALLOWED TO CONTINUE TO HAPPEN NOR HOW GM CAN KNOW ABOUT THE PROBLEM BUT NOT TELL OWNERS OF THE VEHICLE AND/OR FUTURE POSSIBLE BUYERS OF THE VEHICLE. OH WAIT, YEA GM DOESN'T SAY ANYTHING BECAUSE CONSUMERS MIGHT TAKE THEIR BUSINESS ELSEWHERE! I SIMPLY WANTED TO GM TO FIX THE PROBLEM, THAT WAS OBVIOUSLY KNOWN ABOUT, BUT RATHER, GM SIMPLY KEEPS PUTTING THE SAME BAD COMPONENT IN FUTURE VEHICLES!! *TR
I BELIEVE THE SAME PROBLEM WITH THE GM KEY/IGNITION SWITCH IS MORE COMMON THEN WHAT IS BEING REPORTED. THE AVALANCHE 2003 HAS HAD THE SAME LOOSE IGNITION SWITCH FOR YEARS.

I BELIEVE THE SAME PROBLEM WITH THE GM KEY/IGNITION SWITCH IS MORE COMMON THEN WHAT IS BEING REPORTED. THE AVALANCHE 2003 HAS HAD THE SAME LOOSE IGNITION SWITCH FOR YEARS. OUR KEY SYSTEM HAS TO BE JIGGLED AND FORCED TO THE START POSITION 80 PERCENT OF THE TIME. THE IGNITION SWITCH WILL ALSO MOVE THE OFF POSITION WHILE THE VEHICLE IS MOVING AND THE KEY WILL FALL OUT.

IN RESEARCHING THE PROBLEM, I HAVE FOUND OUT THAT THERE WAS A RECALL TO FIX THIS PROBLEM SEVERAL YEARS AGO. I NEVER RECEIVED NOTICE OF THIS RECALL. I HAVE LIVED IN THE SAME LOCATION SINCE 2001, BUT HAVE NEVER BEEN NOTIFIED OF THE RECALL. IF THERE WAS A RECALL AFFECTING THE INSTRUMENT PANEL, I WOULD HAVE TAKEN IT IN. WHY DIDN'T CHEVROLET NOTIFY ALL OWNERS? *TR

1EA11001 · Brake Line Corrosion Failure
Opened Jan 5, 2011 · Closed Apr 8, 2015
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
