2000 GMC Sierra Speed Control & Cruise Problems

I WAS DRIVING BETWEEN 60 AND 65 AND THE TRUCK WOULDN'T SLOW DOWN EVEN I TRIED TO BRAKE THE RPM GAUGE WAS AT 5000 RPM AND THE TRUCK WAS FORCING ME FORWARD I PUT IT IN NEUTRAL AND IT STILL WAS ACCELERATING LIKE THE ENGINE WAS BEING REVVED UP. I MANAGED TO PULL OUT OF TRAFFIC AND KILLED THE ENGINE BUT IT WOULDN'T SHUT OFF I TOOK THE KEYS OUT AND AFTER ABOUT 15 SECONDS IT FINALLY WENTOFF. I TRIED RESTARTING IT SEVERAL TIMES AND IT STILL KEPT ACCELERATING TO THE MAX EVERYONE TIME. I CHECKED THE ACCELERATIONS CABLE AND IT WAS NOT STUCK. *TR

WENT TO STOP AND ABS CAME ON AND PAVEMENT WAS DRY AND NOW IT COMES ON EVERY TIME YOU PUT ON BRAKES AND SLOW DOWN TO 5 OR 6 MPH ... *TR

TL*THE CONTACT OWNS A 2000 GMC SIERRA 1500. ON JANUARY 20, 2008, WHILE DRIVING 65 MPH WITH THE CRUISE CONTROL ACTIVATED, THE CONTACT ATTEMPTED TO DECELERATE, BUT THE VEHICLE FAILED TO RESPOND. THE VEHICLE ACCELERATED TO 80 MPH AND THE CONTACT CALLED THE HIGHWAY PATROL FOR ASSISTANCE. THEY INFORMED HIM TO APPLY THE BRAKES, BUT THAT DID NOT WORK. THEY THEN INFORMED HIM TO PULL OFF ON THE NEXT EXIT. THE CONTACT EXITED THE HIGHWAY, PULLED INTO A PARKING LOT, AND CIRCLED AROUND UNTIL THE VEHICLE DECELERATED TO 35 MPH. HE WAS THEN ABLE TO SHUT OFF THE VEHICLE. HE WAITED SEVERAL MINUTES BEFORE RESTARTING THE VEHICLE AND DROVE AROUND THE PARKING LOT UNTIL HE FELT CONFIDENT THAT THE FAILURE WOULD NOT RECUR. HE HAS NOT YET NOTIFIED A DEALER OR MECHANIC ABOUT THE FAILURE. THE FAILURE MILEAGE WAS 57,000 AND CURRENT MILEAGE IS 60,131. UPDATED 04/29/08. *LJ

THIS IS AN ONGOING PROBLEM WITH THE VEHICLE THE THROTTLE STICKS IN THE IDLE POSITION WHEN THE GAS PEDAL IS RELEASED. IT TAKES A VERY FIRM PUSH TO RELEASE THE THROTTLE AND WHEN IT DOES RELEASE THE VEHICLE LURCHES FORWARD. COMPLAINTS TO THE DEALER RESULT IN A RECOMMENDATION TO HAVE THE FUEL SYSTEM FLUSHED ON AN ONGOING BASIS. SOME RELIEF IS ACHIEVED BY CLEANING THE THROTTLE BODY AREA AROUND THE BUTTERFLY PLATE. THIS HAS TO BE DONE ALMOST MONTHLY. THE DEALER ALSO STATES THAT HE DOES NOT KNOW OF A FACTORY FIXES TO THIS PROBLEM.*AK

WHILE DRIVING AT ANY SPEED ACCELERATED PEDAL STUCK. CONSUMER WOULD HAVE TO DEPRESS THE BRAKE PEDAL NUMEROUS OF TIMES TO STOP THE VEHICLE. DEALERSHIP WILL BE NOTIFIED. *AK

THROTTLE BECOMES STICKY WHEN CLOSED. AS A RESULT EXTRA FORCE IS REQUIRED ON THE ACCELERATOR WHEN INITIALY DEPRESSED. THIS IS AN EXTREMLY DANGEROUS SITUATION ESPECIALY IN PARKING LOTS OR OTHER TIGHT, HIGHLY POPULATED AREAS SINCE EXTRA FORCE IS REQUIRED ON THE ACCELERATOR TO "BREAK IT FREE" ONCE IT DOES "BREAK FREE" THE VEHICLE CAN LUNGE/LURCH FOREWARD UNCONTROLED. THIS SITUATION MAKES SMOOTH THROTTLE CONTROL UNOBTAINABLE. THE PROBLEM SEEMS TO GET WORSE WITH HIGHER AMBIENT TEMPERATURES AS I ASSUME THE THROTTLE PLATE EXPANDS WHEN HOT AND BINDS IN THE THROTTLE BODY. CLEANING THE THROTTLE BODY PROVIDES RELIEF FOR A VERY SHORT PERIOD. I HAVE READ ABOUT THIS PROBLEM ON SEVERAL INTERNET MESSAGE BOARDS AND BELIEVE THAT GM OFFERS AN UPDATED THROTTLE BODY TO CORRECT THIS PROBLEM. DUE TO THE EXTREEM SAFETY HAZZARD I FEEL THAT GM IS NEGLEGENT IN NOT OFFERING TO CORRECT THIS PROBLEM AT THEIR COST, AS GM DOES SEEM TO BE AWARE OF THE DEFICIENCY.*AK

THE CONSUMER WAS AT A STAND STILL WHEN PUTTING THE VEHICLE IN REVERSE, THE CONSUMER PRESSED THE ACCELERATOR PEDAL AND THERE WAS SOME RESISTANCE IN THE ACCELERATOR PEDAL AND THEN THE PEDAL DROPPED STRAIGHT TO THE FLOOR. WHEN THE VEHICLE WAS MOVING BACKWARDS, THE OWNER HIT THE BRAKE AND THE VEHICLE BEGAN TO ACCELERATE ON IT S OWN AT A HIGH RATE OF SPEED. THE CONSUMER CROSSED TWO LANES OF TRAFFIC AND HIT A GUARD RAIL. PROVIDE FURTHER DETAILS. *JB

WHILE APPLYING THE ACCELERATOR PEDAL VEHICLE FAILED TO MOVE. AFTER APPLYING THE ACCELERATOR PEDAL NUMEROUS TIMES THE VEHICLE JUMPED AND SURGED FORWARD. CONSUMER WAS ABLE TO MAINTAIN CONTROL OF THE VEHICLE, AND DROVE IT TO THE DEALER FOR INSPECTION. *AK

I JUST BOUGHT A 2000 GMC SIERRA 1500 PICKUP WITH THE 5.3 LITER ENGINE. THE THROTTLE STICKS WHEN YOU START OFF IN IT FROM A STOPPED POSITION. THE ACCELERATOR HAS A TIGHT SPOT IN IT WHEN YOU FIRST PRESS ON IT. THIS CAN BE VERY DANGEROUS IF IT STICKS TOO MUCH WHEN IT BREAKS LOOSE THE TRUCK WILL GO FORWARD REAL QUICK AND YOU COULD HIT SOMEBODY OR SOMETHING. SOMEONE TOLD ME THAT THE BUTTERFLY HAD CARBON BUILT UP ON IT AND IT NEEDED CLEANING. I CALLED A GM DEALER AND TALKED TO THE SERVICE MANAGER AND HE SAID IT WAS REPORTED BEFORE AND HE WOULD CLEAN THE THROTTLE VALVE FOR $90.00. I THINK THIS SHOULD BE COVERED BY THE MANUFACTURER AND BESIDES IT WILL HAPPEN AGAIN WHEN CARBON BUILDS UP ON IT AGAIN. A PERMANENT FIX NEEDS TO BE PUT IN PLACE AS A RECALL ITEM I THINK. *JB

WE PURCHASED A USED 2000 GMC AND WITHIN A MONTH EXPERIENCED EXPERIENCED THROTTLE STICKING CLOSED SO SEVERE YOU COULD NOT MOVE THE VEHICLE. THEN IF YOU APPLIED A LOT OF PRESSURE IT WOULD LURCH FORWARD. WE TOOK IT IN AFTER A COUPLE OF MONTHS TO A LOCAL GMC DEALER AND THEY SAID IT WAS THE THROTTLE BODY AND IT WAS WARPED AND WOULD NEED TO BE REPLACED. THEY HAD NO EXPLANATION WHY IT WOULD HAVE BECOME WARPED. WE PAID 643.00. WHEN WE PICKED UP THE VEHICLE MY WIFE WENT ONLINE TO RESEARCH IF THERE WERE ANY PROBLEMS AND CAME ACROSS A REFERENCE TO A TSB SO WE CHECKED OUT NHTSA AND UNDER DEFECTS WAS LISTED THE INVESTIGATION THAT IS STILL OPEN ABOUT THE THROTTLE BODY( EA02-015) . WE WERE VERY UPSET AND TOOK IN COPIES OF THE TSB AND SPOKE TO THE SERVICE MANAGER. ON OUR RECEIPT WAS LISTED ANOTHER TSB #00-06-04-007B AS TO WHY THEY REPLACED IT. BUT WITH A CHARGE. WE FELT THEY SHOULD HAD DISCLOSED THIS PROBLEM AND THAT ODI WAS INVESTIGATING IT . THE SERVICE MANAGER SAID HE WOULD CALL GMC AND WE RECEIVED A CALL THE NEXT DAY THAT GMC WOULD BE SENDING US A CHECK FOR 400 TO COVER THE PART. THAT SEEMS FAIR BUT WE DEFINATELY FEEL THIS IS A SAFETY ISSUE. HAD WE NOT BEEN OLDER DRIVERS AND VERY CAUTIOUS WE COULD HAVE BEEN INVOLVED IN AN ACCIDENT. IT COULD HAVE STUCK OPEN AS WELL AS CLOSED. *AK

THE GAS PEDAL STICKS REGULARLY. IT STICKS WHEN THE VEHICLE IS AT A STAND STILL. IT IS VERY HARD TO PRESS THE PEDAL AT TIMES. WHEN I DO PUSH THE PEDAL IT TAKES A LOT OF PRESSURE TO GET IT PUSHED IN AND THE VEHICLE THEN DARTS FORWARD VERY QUICKLY. WHEN IN A TIGHT SPACE THIS CAN BE QUITE DANGEROUS AS I AM UNABLE TO CONTROL IT. 8NLM

THE ACCELERATOR PEDAL BECAME STUCK.*JB THE CONSUMER STATED THE PROBLEM STARTED DURING THE WARRANTY PERIOD, HOWEVER THE DEALERSHIP CLAIMED IT WAS NOT A WARRANTY ISSUE. *JB

THE ACCELERATOR PEDAL STICKS INTERMITTENTLY CAUSING THE VEHICLE TO SURGE FORWARD WITHOUT WARNING. DEALER HAS REPAIRED 4X WHILE UNDER WARRANTY, BUT PROBLEM WOULD REOCCUR APPROXIMATELY 2 WEEKS AFTER SERVICING. PH

CONSUMER CALLED COMPLAINING ABOUT HAVING PROBLEMS WITH THE THROTTLE PEDAL GETTING STUCK. DEALER WAS CONTACTED AND STATED THAT HE NEEDED TO HAVE A COMPLETED CLEAN UP ON THE VEHICLE. MR SCC

CONSUMER STATES WHILE DRIVING THE VEHICLE AND WITHOUT WARNING THE VEHICLE GAS PEDAL GETS STUCK. TS GAS PEDAL STUCK AND HAD TO BE TAPPED TO GET TO MOVE. THIS CAUSED EXCESSIVE ENGINE RPMS POSSIBLY CAUSING AN ACCIDENT. CONSUMER HAD TO KEEP FOOT ON BRAKE TO PREVENT VEHICLE FROM LURGING FORWARD. *TT

MR

THROTTLE PEDAL STICKS INTERMITTENTLY. DEALER CONTACTED. FEEL FREE TO PROVIDE ANY FURTHER INFORMATION.*AK

ACCELERATOR STICKS WHEN YOU PUSH ON IT. IT HAS GOTTEN WORSE.*AK

THE ACCELERATOR PEDAL ON THE PICKUP HAS AND STILL DOES STICK WHEN TRYING TO ACCELERATE SLIGHTLY/SLOWLY FORWARD OR BACKWARD AS IN PARALLEL PARKING. THE PROBLEM IS WORSE IN HOT WEATHER. THE DEALER, DURING WARRANTY PERIOD, TOLD ME THEY FOUND NO DEFECT AND KNEW OF NO DEFECT. I LEFT IT GO. MY FRIEND WHO OWNS A SATURN SEDAN TOLD ME HE HAS THE SAME PROBLEM WITH THE ACCELERATOR STICKING DURING SMALL MANEUVERS. I HAVE JUST READ THAT THERE ARE TWELVE COMPLAINTS SIMILAR TO MY ISSUE THAT HAVE BEEN REPORTED TO YOUR AGENCY. I AM REPORTING THE SAME AT PRESENT THOUGH THE PROBLEM HAS BEEN ONGOING FOR TEN YEARS. IT MAKES CLOSE PARKING DIFFICULT AND I TRY TO AVOID THE SITUATION BECAUSE OF SUCH. I HAVE ALMOST CRASHED MANY TIMES BECAUSE OF THE AMOUNT OF OVERPRESSURE TO THE ACCELERATOR TO MAKE THE TRUCK MOVE. *TR

MY ACCELERATOR PEDAL HAS BEEN STICKING FOR QUITE SOME TIME. IT WAS VERY SUBTLE AT FIRST AND I DIDN'T GIVE IT MUCH THOUGHT. I HAD INTENDED TO MENTION IT TO MY DEALER BUT DIDN'T BECAUSE I BEGAN HAVING PROBLEMS WITH NOT BEING ABLE TO START MY TRUCK. AFTER ABOUT FIVE OR SIX TRIPS TO THE DEALER THEY FINALLY INSTALLED A NEW COMPUTER COMPONENT THAT HAD BEEN RECALLED AND FIXED THE PROBLEM. NOW MY WARRANTY IS UP AND THE GAS PEDAL SEEMS TO STICK MORE OFTEN. I CAN LIVE WITH IT WHILE TRAVELING BECAUSE IT DOESN'T STICK AT A CURRENT SPEED THAT I AM DRIVING AT; IT STICKS WHEN I WANT TO START OUT OR ACCELERATE. MY CONCERN IS THAT RECENTLY WHEN I STARTED THE TRUCK IT STUCK TO THE POINT THAT WHEN I TRIED TO DEPRESS IT STUCK AND THEN FREED TO WHERE I DARTED OUT OF MY PARKING SPOT. THIS WAS SCARY AND I DECIDED I HAD BETTER REPORT IT TO THE DEALER. I HAD A SERVICE COMPLETED ON MAY 23, 02 AND RAISED MY CONCERNS WITH SHAWN D. IN THE SERVICE DEPT. AND ANOTHER GENTLEMAN (NAME UNKNOWN). THE UNKNOWN PARTY ASKED ME IF MY TRUCK WAS STILL UNDER WARRANTY AND I TOLD HIM NO. I ALSO POINTED OUT THAT THIS SHOULD BE A RECALL ITEM AS IT COULD BE A MAJOR ACCIDENT WAITING TO HAPPEN. HE SAID THEY WERE AWARE OF THE PROBLEM AND THAT IT WAS A CARBON BUILDUP THAT TOOK ABOUT AN HOUR TO REPAIR. HE SAID GM HASN'T DECIDED TO RECALL IT AT THIS POINT. I DON'T FEEL THAT I SHOULD HAVE TO PAY FOR A POTENTIAL SAFETY HAZARD THAT WAS A MANUFACTURER'S BOO BOO. I AM SURPRISED THAT A COMPANY THAT HAS SUCH WONDERFUL MARKETING ADS STRESSING PROFESSIONAL SERVICE AND PRIDE WOULD OVERLOOK A PROBLEM THAT COULD PROVE EXTREMELY COSTLY TO THEM IN THE FUTURE. I HOPE YOU CAN BE OF SOME ASSISTANCE TO ME.*AKI
