MY 1999 CHEVROLET TAHOE INTERMITTENTLY FAILS TO START. THE ENGINE CRANKS AND THEN DIES. IT WILL DO THIS, THEN I WILL LET IT SIT FOR A WHILE (45 MIN. TO SEVERAL HOURS) AND I'LL GO BACK OUT AND IT WILL START RIGHT UP. MECHANICS HAVE TOLD ME THERE'S NOTHING THAT CAN BE DONE UNTIL IT DOES IT CONSISTENTLY. ON 8/19/04, I TRIED TO START IT @ 7:45 A.M. IT TOOK ME UNTIL 8:25 A.M. TO START IT, AFTER WHICH I DROVE TO WORK (LATE). I WENT BACK OUT TO LEAVE THE OFFICE @ 10:30 A.M. - NO START. HAD IT TOWED TO DEALERSHIP - STARTED RIGHT UP. ACCORDING TO THE BCM, A CODE OF DTC1626 SHOWED UP, WHICH INDICATES SOMETHING LIKE THE THEFT DETERRENT SYSTEM IS PREVENTING THE FUEL ENABLE SIGNAL FROM BEING RECEIVED. THE DEALERSHIP SOLDERED THE WIRING CONNECTIONS ON THE THEFT DETERRENT HARNESS (PREVIOUSLY, CONNECTIONS WERE CRIMPED), WHICH THEY SAID HAD HELPED SEVERAL OTHER TAHOE OWNERS. TWO DAYS LATER, MY HUSBAND WAS STRANDED WITH MY NON-STARTING TAHOE AND MY RECEIPT FOR $161.84 FOR "FIXING" THE PROBLEM. THERE HAS TO BE A FIX FOR THIS PROBLEM!! THERE ARE AT LEAST 6 OTHER SIMILAR COMPLAINTS ON THIS WEBSITE AS WELL AS 4 SERVICE BULLETINS, BUT NO ONE SEEMS TO HAVE A CLUE AS TO WHY THIS IS HAPPENING OR HOW TO PREVENT IT! I'VE OWNED 2 SILVERADOS AND 1 YUKON SINCE 1984 AND HAVE BEEN EXTREMELY HAPPY WITH GM'S PRODUCTS, BUT THIS TAHOE TAKES THE CAKE! IF IT HADN'T BEEN AN ANNIVERSARY GIFT FROM MY HUSBAND, I WOULD HAVE SOLD IT BY NOW! *AK

I HAVE OWNED A 1999 CHEVROLET TAHOE FOR A LITTLE OVER 2 YEARS. ON AT LEAST 6 OCCASIONS, THE VEHICLE WON'T CRANK UP.

I HAVE OWNED A 1999 CHEVROLET TAHOE FOR A LITTLE OVER 2 YEARS. ON AT LEAST 6 OCCASIONS, THE VEHICLE WON'T CRANK UP. THE ENGINE DOESN'T EVEN TURN OVER AS IF TO CRANK, BUT IF YOU WAIT 1 TO 12 HOURS, IT WILL CRANK RIGHT UP. THE ENGINE DECIDES HOW LONG IT WILL TAKE TO RESET ITSELF AND ALLOW US TO CRANK IT. WE ASKED A FRIEND WHO IS A CHEVROLET MECHANIC ABOUT THE POSSIBLE CAUSE OF THIS PROBLEM. HE SAID THAT IT WAS A COMMON PROBLEM WITH TAHOES OF THAT YEAR. HE SAID THAT THE VEHICLE ALARM SYSTEM THINKS THAT IT HAS BEEN BROKEN INTO, AND TRIES TO PROTECT ITSELF FROM THEFT AND WON'T CRANK. ON NONE OF THE OCCASIONS THAT IT HAS DISABLED ITSELF HAVE WE HAD THE ALARM SYSTEM DISRUPTED. OUR MECHANIC FRIEND SAYS HE HAS SEEN IT SEVERAL TIMES, BUT THE CHEVROLET COMPANY SAYS THAT THEY NEVER HEARD OF THIS PROBLEM. IT COSTS SEVERAL HUNDRED DOLLARS TO FIX THE PROBLEM, THEREFORE I LIVE WITH IT EVERY DAY. ON A RECENT VACATION TO THE MOUNTAINS, I WAS AFRAID TO TURN THE VEHICLE OFF WHEN WE GOT OUT OF IT TO TAKE PICTURES FOR FEAR THAT IT WOULDN'T START BACK UP. IS THERE ANY INFORMATION ON THIS PROBLEM? HAVE YOU HEARD IT BEFORE?*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.
