CONSUMER'S VEHICLE FOLLOWED A SCHOOL BUS, NO CHILDREN WERE ON THE BUS. AROUND 7:50 AM THE BUS STOPPED FOR RED LIGHT. SPEED WAS APPROXIMATELY 20-25 MPH. AS THE BRAKE PEDAL WAS PUSHED DOWN THE VEHICLE BEGAN TO SLOW DOWN, BUT IT DID NOT SLOW AS QUICKLY AS NORMAL. THE ABS ENGAGED, BUT THE VEHICLE CONTINUED TO PROCEED FORWARD. THERE WAS PLENTY OF ROOM AND TIME THAT THE VEHICLE SHOULD HAVE STOPPED BUT IT DID NOT. THE VEHICLE BUMPED THE REAR OF THE BUS, PUSHING IN THE BUMPER OF VEHICLE. THIS INCIDENT FOLLOWED THE PATTERN SET FORTH IN NHTSA RECALL 05V379000 ON AUGUST 29 2005. HOWEVER, ON NOVEMBER 18, 2005 THE LOCAL DEALER PERFORMED THE PROCEDURE THAT GMC RECOMMENDED TO CORRECT THIS PROBLEM, BUT I FEEL THAT THE VEHICLE STILL FAILED IN THIS INCIDENT.*AK

HAVE HAD PROBLEMS WITH BRAKES. THEY DO NOT STOP PROPERLY, YOU NEVER KNOW WHEN THEY ARE GOING TO WORK OR NOT. MY WIFE HAS ON DIFFERENT OCCASIONS ON THE FREEWAY APPLIED THE BRAKES QUICKLY AND THE PEDAL WENT DOWN TO THE FLOOR, THANK GOD THERE WAS AN EMERGENCY LANE WHERE SHE SWERVED OUT TO. IT HAS ALSO HAPPENED TO ME. WE ARE TOLD THAT YOU DO NOT PUMP THE BRAKES ON AN ABS BRAKING SYSTEM, WELL MY WIFE CAME HOME AND TOLD ME BY PUMPING THE PEDAL THE BRAKES SEEM TO STOP A LITTLE BETTER. NOW WHAT DO YOU THINK THAT IS TELLING YOU??? I HAVE BEEN IN THE AUTOMOTIVE BUSINESS FOR OVER 40 YEARS, AND HAVE NEVER HAD A PROBLEM LIKE THIS. THEY HAVE YET TO FIX THE PROBLEM BECAUSE THEY SAY THERE IS NOTHING WRONG, AND SINCE THE VEHICLE DID NOT COME IN ON A HOOK AND OR WAS NOT IN A ACCIDENT THEY WOULD NOT DO ANYTHING. WE HAVE BEEN COMPLAINING ABOUT THE BRAKES SINCE WE PURCHASED THE VEHICLE. AT THIS POINT I WILL NEVER PURCHASE ANOTHER GMC AGAIN, AND I AM LETTING EVERYONE KNOW THIS. HOPE YOU CAN HELP OR HAVE SOME SUGGESTIONS. THANK YOU FOR YOUR TIME IN THIS MATTER. MANNY. *NM

"SERVICE 4WD" AND WHEN GENTLY APPLY/PRESSING ON THE BRAKE PEDAL, THE IS SOME KIND OF LOUD MECHANISM NOISE IN THE FRONT WHEEL DRIVER SIDE, AND PREVENT THE BRAKE PEDAL FROM COMING DOWN.

I HAVE A 2002 GMC YUKON XL. I BOUGHT THE VEHICLE BRAND NEW IN JUNE OF 2002. AT 376 MILES MY BRAKE SYSTEM LOCKED UP. I HAVE CONTINUED TO HAVE THIS PROBLEM EVER SINCE. AS YOUR DRIVING THE BRAKES APPLY AND YOU LOOSE CONTROL OF YOUR STEERING. THIS PROBLEM DOES NOT OCCUR ALL THE TIME, BUT DOES HAPPEN. THEY HAVE REPLACED MY MASTER CYLINDER, POWER BOOSTER, AND ALL 4 ROTORS. THIS PROBLEM IS STILL NOT FIXED AND BECAUSE THE DEALERSHIP CAN NOT GET IT TO DUPLICATE THE PROBLEM WHILE THEY ARE DRIVING IT, THEY SAY THERE IS NOTHING ELSE THEY CAN DO. I AM FILING THIS COMPLAINT BECAUSE I FEAR FOR MY SAFETY. THE LAST TIME IT HAPPENED ON 9/11/03 IT WAS TOWED TO THE NEAREST DEALERSHIP, THEY HAVE INFORMED ME THERE IS NOTHING THEY CAN DO. I HAVE LEFT THE VEHICLE THERE BECAUSE I FEAR DRIVING IT. LAST THING I HEARD WAS THEY WERE SHIPPING IT TO THE DEALERSHIP WHERE I BOUGHT IT BECAUSE IT WAS THERE PROBLEM. PLEASE IF YOU KNOW ANYTHING I CAN DO PLEASE LET ME KNOW. I WOULD LIKE TO ADD THAT THERE HAS BEEN EVIDENCE OF DEFECT BECAUSE THE ROTORS HAVE SHOWN DAMAGE DUE TO DEFECT. *JB

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.
