I PURCHASED MY 1999 CHEVY TAHOE IN 2004 WITH 87,000 MILES FROM ORIGINAL OWNER. I RECEIVED ALL MAINTENANCE RECORDS FROM ORIGINAL OWNER, AS WELL AS ORIGINAL DEALERSHIP PRICE/OPTION STICKER. I NOTICED ONCE OVER 100,000 MILES THERE WAS AN ELECTRICAL MALFUNCTION OR PROBLEM, LIKE A POWER SURGE ANYTIME THE POWER WINDOW BUTTONS ARE DEPRESSED AND WHEN I ACCELERATE, THERE IS A SURGE AND WHEN TRUCK SLOWS DOWN OR IS IN PARK, THERE IS N SURGE. THERE IS SUDDEN ENERGY! THERE IS ALSO A PROBLEM WITH THE DASHBOARD/RADIO AND SWITCH BUTTONS BELOW LIGHTS WORKING. THEY HAVE FAILED! ELECTRICAL PROBLEMS CAN CAUSE FIRES AND I HAVE NOTICED IT IS NOT MY TAHOE ONLY WITH THE SAME EXISTING ELECTRICAL PROBLEMS, AS I HAVE BEEN LOOKING FOR A SECOND VEHICLE, AS I HAVE MY KIDS BOTH OF DRIVING AGE AND MY 1999 TAHOE LS IS MY ONLY VEHICLE. I FEEL SAFE ON THE ROAD IN MY TAHOE. I LOVE THE FOUR WHEEL DRIVE OPTION, AS I LIVE IN MINNESOTA AND I COULD NOT LIVE WITHOUT IT OVER THE WINTER MONTHS! I AM ALSO VERY PROUD TO POINT OUT, MY TAHOE HAS 343,000+ MILES ON IT AND STILL GOING STRONG!!!! I CAN NOT AFFORD A NEW TAHOE, AS I AM ON A FIXED DISABILITY INCOME NOW, SO I AM SHOPPING FOR A 1999 OR NEWER AT A REASONABLE PRICE. I AM SATISFIED WITH ALL THE YEARS I HAVE DRIVEN MINE AND HOPE TO GET MANY MORE YEARS OUT OF IT. PEOPLE ARE AMAZED WHEN I TELL THEM HOW MANY MILES ARE ACTUAL MILES ON MY TAHOE. I AM AMAZED, AS WELL. :) [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

VEHICLE FAILS TO SLOW DOWN WHEN ACCELERATOR IS RELEASED. WHEN RELEASNG THE ACCELERATOR I NOTICE THAT TACHOMETER REMAINS AT THE SAME RPM. AT FIRST THIS TROUBLE WAS INTERMITTANT BUT HAS PROGRESSIVELY FAILED MORE OFTEN UNTIL NOW IT IS CONTINOUS. THE ONLY WAY TO SLOW THE VEHICLE DOWN IS BY BRAKING USING THE VEHICLE'S BRAKES. WHEN THE ENGINE BRAKING WAS WORKING OK, ABOUT TWO SECONDS AFTER TAKING YOUR FOOT OF THE ACCELERATOR IT WOULD SLOW DOWN PROPERLY. I CONTACTED THE DEALER ON 2/22/2001 AND HE SUPPOSEDLY TOOK IT FOR A TEST RUN, HOWEVER, THE ODOMETER IN AND OUT WERE IDENTICAL, 26528 MILES. WHEN I CONTACTED THEM AGAIN, THEIR LATEST RESPONSE WAS THAT THEY ALL DO THAT AND THERE IS NOTHING I CAN DO TO HAVE IT CORRECTED. I FEEL THAT IF THE PROBLEM IS NOT CORRECTED SHORTLY IT WILL CAUSE PREMATURE BRAKE FAILURE BECAUSE OF EXCESSIVE BRAKING WHICH COULD LEAD TO AN ACCIDENT.*AK

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.
