VEHICLE HAS ONLY 21,650 M ON IT, USED MOSTLY ON WEEKENDS AND IN THE SNOW IN WINTER. IT WAS DOING FINE UNTIL 9/18/16 WHEN SUDDENLY I NOTICED MY BRAKE WAS NOT RESPONDING AS USUAL. I HAD TO PUSH THE PEDAL TO THE FLOOR REPEATEDLY TO STOP, BARELY MISSED HITTING THE CAR IN FRONT OF ME. I WAS ON ONE OF MY CITY STREETS GETTING BACK HOME AFTER GROCERY SHOPPING. DROVE HOME SLOWLY AND VERY CAREFULLY. HAD IT TOWED TO A NEARBY GM DEALER. HE SAYS MOST OF THE BRAKE LINES AND SOME HOSES HAVE RUSTED, NEED TO BE REPLACED. THAT WOULD BE 15-16 HOURS LABOR AND WILL COST ME $ 2000.00. IT SNOWS HERE QUITE A BIT AND AFTER THE SEASON, I ALWAYS WASH MY VEHICLES WITH EMPHASIS ON THE UNDERSIDE TO REMOVE THE SALT AND CHEMICALS. BESIDES, ON THIS VEHICLE I HAD TO REPAINT THE HOOD TWICE, ROOF ONCE AND REPLACE THE REAR BUMPER SO FAR- ALL DUE TO RUST. NOW MY FRONT BUMPER IS SHOWING SIGNS OF RUST. WHAT'S THE MATTER - WITH ALL THIS EXCESSIVE RUSTING ON THIS VEHICLE. I HAVE MY OTHER SUV PARKED RIGHT BESIDE THIS AT HOME AND USE IT IN THE WINTER TIME. IT IS MUCH OLDER THAN YUKON AND THERE IS NO RUST PROBLEM AT ALL WITH IT. LOOKS LIKE THERE IS SOME SERIOUS PROBLEM WITH THE METAL USED IN THIS VEHICLE OR LACK OF QUALITY CONTROL. GM DID A BAD JOB WITH THIS VEHICLE. THEY SAY THERE WAS NO RECALL ON THIS MODEL. WOULD LIKE TO KNOW IF I CAN GET COMPENSATED BY GM FOR ALL THIS HARDSHIP. DO NOT KNOW WHAT ELSE IS IN STORE WITH THIS VEHICLE IN FUTURE. HAVE TO GET THE BRAKE JOB DONE RIGHT AWAY BUT VERY PRICEY FOR MY BUDGET. PLEASE CHECK INTO THIS PROBLEM AND LET ME KNOW HOW TO PROCEED. LOOKING FORWARD TO HEARING FROM YOU SOON. THANKS, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

HAD TO STOP IN A HURRY ON THE FREEWAY AND WAS GOING ABOUT 60 MILES AN HOUR AND HIT THE BRAKES, I BELIEVE THE ABS LOCKED UP AND I FISHTAILED FROM THE LEFT TO THE RIGHT AND BACK TO THE LEFT AGAIN. ENGINE SHUTOFF AUTOMATICALLY AND CHECK ENGINE LIGHT CAME ON. THIS NEARLY CAUSED A MULTI CAR COLLISION WITH A POSSIBLE BRIDGE FLY AWAY AS WE WERE ON A BRIDGE AT THE TIME. LUCKILY THROUGH DEFENSIVE DRIVING WAS ABLE TO GAIN CONTROL OF THE VEHICLE AND KEEP IT FROM HITTING ANYTHING OR ANYONE, HOWEVER NOW WHEN TURNING RIGHT OR LEFT THERE IS A SQUEAK AT EVERY ROTATION WHEN GOING SLOW. ALSO THE VEHICLE SLOWLY HESITATES COMING TO A STOP AND ABS WILL SOMETIMES START ENGAGING CAUSING NEAR COLLISIONS. *TR

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.
