I HAVE JUST SUBMITTED A FIRST COMPLAINT # 10552595 FOR DEFECTIVE GMC YUKON BRAKE LINES. I AM NOW SUBMITTING SECOND COMPLAINT FOR A SUBSEQUENT INCIDENT WITH THE SAME VEHICLE. ON OCT. 5, 2013 I WAS DRIVING ALONE TO THE SUPERMARKET IN PENNSYLVANIA. AS I WAS STOPPING FOR AN UPCOMING STOP SIGN, MY BRAKES FAILED TO OPERATE, AGAIN! THE BRAKE PEDAL AGAIN WENT COMPLETELY TO THE FLOOR. AS THERE WAS ALMOST NO STOPPING POWER LEFT, I AGAIN PULLED THE EMERGENCY BRAKE AND DOWNSHIFTED TO LOW, AND PARTIALLY SLOWED, AND STOPPED JUST AFTER THE INTERSECTION. I WAS WITHIN SIGHT OF MY AUTO SHOP, AND I VERY SLOWLY PROCEEDED THROUGH ONE ADDITIONAL INTERSECTION TO THE SHOP. WHEN I PULLED INTO HIS PARKING LOT, I COULD SEE THE HYDRAULIC BRAKE FLUID WAS RUNNING OUT OF THE REAR BRAKE LINE ONTO THE PAVEMENT! MY MECHANIC NOW TOLD ME THAT THE REAR BRAKE LINES WERE RUSTED TO THE POINT OF CAUSING A MAJOR BRAKE FLUID LOSS. HE REPLACED THE REAR BRAKE LINES WITH STAINLESS STEEL TUBING AND FITTINGS. I HAD TO PAY $509.45 TO MAKE THIS ADDITIONAL BRAKE LINE REPAIR. BASED UPON THE NHTSA IS INVESTIGATING THESE DANGEROUS AND DEFECTIVE GMC BRAKE LINES IN THE 'RUST STATES' INCLUDING MY HOME IN PENNSYLVANIA, THE US GOVT MUST NOW FORCE GMC TO RECALL THESE INFERIOR CORROSIVE BRAKE LINES TO AVOID THE CHANCE FOR FATAL ACCIDENTS. GMC SHOULD REIMBURSE ME FOR MY COSTS, NOW TOTALING $ 994.80. THIS IS NOW THE SECOND NHTSA INCIDENT COMPLAINT I HAVE FILED IN 2013 FOR THE TOTAL FAILURE OF MY CORRODED AND BURST GMC YUKON BRAKE LINES. (PLEASE NOTE THE MILEAGE OF MY VEHICLE ON 4/19/13 WAS 132,593 AND THEN ON 10/5/13 IT WAS 137,813.) -[XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

THE BRAKE PEDAL WENT COMPLETELY TO THE FLOOR.

I PULLED TO THE SIDE OF THE ROAD AND HAD THE CAR TOWED TO MY AUTO SHOP. MY MECHANIC TOLD ME THE FRONT BRAKE LINES WERE RUSTED TO THE POINT OF CAUSING A MAJOR BRAKE FLUID LOSS. HE REPLACED THE BRAKE LINES WITH STAINLESS STEEL TUBING AND FITTINGS. I HAD TO PAY $485.35 TO MAKE THIS REPAIR. I NOW KNOW NHTSA IS INVESTIGATING THESE DANGEROUS AND DEFECTIVE GMC BRAKE LINES IN THE 'RUST STATES' INCLUDING MY HOME IN PENNSYLVANIA. THE US GOVT SHOULD FORCE GMC TO RECALL THESE INFERIOR CORROSIVE BRAKE LINES TO AVOID THE CHANCE FOR FATAL ACCIDENTS, AND GMC SHOULD REIMBURSE ME FOR MY COSTS.

THE REAR MAIN BRAKE LINE BROKE RIGHT HALF INTO WHEN I HAD TO APPLY A VERY HARD STOP ON INTERSTATE 64 I WAS TRAVELING AT 65 MPH WHEN A SMALL CAR ABRUPTLY CHANGED LANES THERE WASN'T EFFICIENT ENOUGH SPACE FOR THE CAR TO MOVE IN AS HE MOVED OVER I HAD TO HIT MY BRAKE RATHER HARD TO GIVE THIS IDIOT ENOUGH ROOM TO MERGE IN THE ABS KICKED IN AND THE TIRES SQUEALED I CAME VERY VERY CLOSE TO REAR ENDING THIS GUY BUT I HAD JUST ENOUGH BRAKE TO SLOW MY CAR UP WITHOUT INCIDENT AFTER THAT MY BRAKES WENT TO THE FLOOR WHEN I EXITED THE INTERSTATE SOMEHOW IT DID STOP LUCKY ME. SOON AS I SAW A STORE I STOPPED AND PURCHASED 4 CANS OF BRAKE FLUID REFILLED THE RESERVOIR AND MADE IT HOME WITH THAT. I JACKED MY YUKON UP AND SAW A VERY RUSTY STEEL LINE BROKE OFF AT THE FITTING IT DIDN'T PULL OUT OF THE FITTING IT ACTUALLY BROKE INTO AND OF COURSE FLUID WAS EVERYWHERE. THIS INCIDENT COULD HAVE BEEN A BAD DISASTER THERE WAS A LOT OF TRAFFIC ON THE INTERSTATE RIGHT AT THE PEAK OF THE DAY WHEN EVERYONE WAS LEAVING WORK TRYING TO GET HOME. I AM THANKING MY LUCKY STARS I MADE IT HOME SAFE. NOW I HAVE TO FIGURE OUT THE REPAIR PART OF THIS WHOLE THING. *TR

Consequence & remedy
Consequence: THIS CAN CAUSE INCREASED STOPPING DISTANCES DURING LOW-SPEED BRAKE APPLICATIONS, WHICH COULD RESULT IN A CRASH.
Remedy: DEALERS ARE TO REMOVE THE WHEEL SPEED SENSOR AND THOROUGHLY CLEAN THE WHEEL SPEED SENSOR MOUNTING SURFACE ON THE BEARING, APPLY RUST INHIBITOR TO THE CLEANED SURFACE, GREASE THE MOUNTING SURFACE, REINSTALL THE WHEEL SPEED SENSOR, AND CHECK THE PEAK-TO-PEAK OUTPUT VOLTAGE TO ENSURE THE WHEEL SPEED SIGNAL IS WITHIN SPECIFICATIONS. THE RECALL BEGAN SEPTEMBER 22, 2005. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438 OR GMC AT 1-866-996-9463.

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.

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.
