TRANSMISSION FAILS TO ENGAGE DRIVE UNLESS PLACED INTO REVERSE. WHEN STUCK IN DRIVE, PUSHING ON THE ACCELERATING WILL CAUSE CAR TO MOVE FORWARD SLOWLY, UNTIL THEIR IS A LOUD VIOLENT SOUND FROM THE REAR OF THE VEHICLE AR WHICH POINT THE VEHICLE WILL ENGAGE DRIVE AND PROCEED IN A SLUGGISH FASHION. THE VEHICLE HAS BEEN AT THE DEALER WHO HAD INVESTIGATED AND FIXED THE PROBLEM SINCE NOVEMBER 2005 AND THE PROBLEM PERSISTS TODAY (2-7-2006). THE PROBLEM PRESENTED ITSELF AFTER THE DEALERSHIP FLUSHED AND CHANGED THE TRANSMISSION FLUID AT APPROXIMATELY 53000 MILES (THE SERVICE DEPT RECOMMENDED THE SERVICE). THE TRANSMISSION HAS BEEN FAULTY EVER SINCE. THE VEHICLE IS 2002 GMC YUKON, 2 WD.*JB

THE PARKING BRAKE ON OUR 2002 YUKON DOES NOT HOLD ONCE THE REAR BRAKES HAVE WARMED UP. WHEN THE VEHICLE IS ALLOWED TO SIT FOR A FEW HOURS AND THE BRAKES COOL, THE PARKING BRAKE HOLDS. SINCE NEW, THE PARKING BRAKE PEDAL HAS GONE ALL THE WAY TO THE FLOOR, AND THE DEALER TOLD ME THIS IS NORMAL. I'VE COMPLAINED TO THE DEALER ABOUT THIS PROBLEM IN THE PAST WHEN I TOOK IT FOR STATE INSPECTION, AND I WAS TOLD IT WAS A MINOR ADJUSTMENT PROBLEM AND IT HAD BEEN FIXED. SINCE THE CAR WAS COLD WHEN I PICKED IT UP, THE PARKING BRAKE DID WORK FINE. I DIDN'T REALIZE UNTIL LAST SUMMER THAT THE PARKING BRAKE DOESN'T HOLD ONCE THE ROTOR ASSEMBLY IS WARMED UP. CLEARLY, THIS IS A DANGEROUS SITUATION IF PARKED ON A STEEP INCLINE. THE DEALER HAS TOLD ME NOT TO WORRY BECAUSE THEY SAY THE VEHICLE IS SAFE WHEN IN PARK. I DISAGREE. *JB

I AM WRITING TO TALK TO YOU ABOUT MY RECURRING ISSUES WITH MY STEERING COLUMN IN MY 2002 YUKON XL. IN SHORT, IT RATTLES. ON THE ROAD, IT RATTLES AT A LOW THUD, THUD, THUD SOUND. TURNING CORNERS, IT RATTLES WITH THE SAME SOUND. INITIALLY, WHEN I TOOK IT TO BERGLUND CHEVROLET, IN ROANOKE, VA, THEY ATTEMPTED TO REMEDY THE PROBLEM WITH A LUBE KIT. WHEN THE PROBLEM SURFACED AGAIN, I BROUGHT IT BACK AND THE INTERMEDIATE STEERING COLUMN WAS REPLACED. 20,000 MILES LATER, I FACE THE PROBLEM FOR THE 3RD TIME. I DRIVE ON THE ROAD, NEVER OFF ROAD. I HAVE OWNED A NUMBER OF VEHICLES, AND ALWAYS HOLD ON TO THEM UNTIL THEY EXCEED 150,000 MILES. NEVER HAVE I HAD TO REPLACE ONE STEERING COLUMN, IN ANY VEHICLE, AND I OBVIOUSLY HAVE NEVER HEARD OF A VEHICLE REQUIRING MORE THAN ONE. I HAVE LEARNED FROM GMC THAT THERE WAS A FIRST GENERATION FIX AND A SECOND-GENERATION FIX. I REALLY DON'T KNOW WHICH GENERATION I GOT, BUT I DO KNOW IT WAS NOT A FIX. AFTER SOME ARGUING, THE FIRST REPAIR WAS COVERED. THE SECOND WAS COVERED, AS WELL, BUT ONLY AFTER ARGUING ONCE MORE. IT SEEMS PERFECTLY CLEAR TO ME THAT THIS SHOULD BE REPAIRED AGAIN, AT NO COST TO ME, BECAUSE I HAVE NEVER RECEIVED A SATISFACTORY REMEDY TO THIS PROBLEM '' A PROBLEM ACKNOWLEDGED BY GMC AS NEEDING TO BE REMEDIED. IT IS OBVIOUS THAT MY VEHICLE HAS NOT GOT THE STEERING COLUMN SOLUTION THAT WORKS. I HAVE SAFETY CONCERNS. NO ONE SHOULD EXPECT TO REPLACE A STEERING COLUMN ON A VEHICLE EVERY 20,000 MILES. IT IS NOT A FILTER OR FLUID THAT NEEDS CHANGING AT INTERVALS, AND I REFUSE TO HAVE THIS TREATED AS IF IT WERE REGULAR MAINTENANCE. I AM WORRIED ABOUT THE SAFETY OF A UNIT THAT WEARS OUT SO QUICKLY, AND AM VERY DISTURBED BY THE COMPLACENCY OF GMC ABOUT SUBJECTING ME TO CONTINUOUS REPAIRS, AND APPARENTLY HIDING BEHIND POLICIES RATHER THAN DOING THE RIGHT THING WITH A CUSTOMER. *NM

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.

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.
