1999 GMC Sierra complaints

WHILE APPROACHING A STOP SIGN AT APPROXIMATELY 20 MPH, THE DRIVER SIDE SEAT ADJUSTMENT BROKE FREE AND THE SEAT SLID FORWARD. BECAUSE OF THE ANCHORAGE OF THE SEAT BELT BEING THE SEAT ITSELF, NOTHING HELD ME BACK FROM CONTACT WITH THE STEERING WHEEL. FORTUNATELY THIS HAPPENED AT A LOW RATE OF SPEED. I AM IN THE PROCESS OF SEEKING REIMBURSEMENT FOR REPAIR COST IN THE AMOUNT OF $513.11 FROM GM WHO WOULD NOT COVER THE REPAIR BECAUSE THE VEHICLE IS OUT OF WARRANTY.*AK

ABS AND BRAKE LIGHT ARE ON. HAD PROBLEM DIAGNOSED BY DEALER AND WAS TOLD TRUCK NEEDED A NEW EBCM (ELECTRONIC BRAKE CONTROL MODULE). PART ALONE IS $800.00 PLUS TAX AND LABOR. GOT ON A GMC TRUCK OWNERS WEBSITE AND FOUND MANY OTHER OWNERS WITH THE SAME PROBLEM.*AK

WHILE DRIVING 60 MPH THE VEHICLE WAS INVOLVED IN A FRONT END COLLISION. NEITHER OF THE FRONTAL AIR BAGS DEPLOYED. *AK *SCC *NLM

ABS LIGHT IS ON, TOOK THE TRUCK TO THE GARAGE, SAID IT NEEDED A NEW ECBM, 700.00VERY CAR AND TRUCK ON THE ROAD HAS A PROBLEM, NOW, WHY SHOULDN`T THE MANUFACTURES, BE RESPONSIBLE FOR THERE MISTAKES, WE PAY ENOUGH FOR THERE MISTAKES.*AK

WHILE ON A TRIP GAS GAUGE MALFUNCTIONED. THE FUEL GAUGE REMAINED ON 3/4 WHILE THE MILEAGE WAS 335. WHEN FILLING THE TANK IT SHOWED FULL AFTER 4 GALLONS WERE DELIVERED. THE PROBLEM CONTINUED THEREAFTER TILL PRESENT. THE ONLY WAY TO KNOW THE FUEL LEVEL IS BY THE TRIPOMETER AND GUESS WORK.*AK

WHILE TRAVELING WINDSHIELD WIPERS WOULD WORK INTERMITTENTLY DURING USAGE, CAUSING POOR VISIBILITY. *AK

THE CONSUMER STATED ANYTIME THE VEHICLE CAME TO A STOP AT AN INTERSECTION, STOP SIGN, LIGHT OR UNEVEN PAVEMENT, THE ANTI-LOCK BRAKES ENGAGED, WHICH CAUSED THE BRAKES TO MOMENTARILY FAIL. *AK *JB

ABS MODULE FAILED, CAUSING PUMP TO RUN CONTINUOUSLY. NECESSITATED REMOVING FUSE ON ABS SYSTEM WHICH CAUSES BRAKE LIGHT & ABS LIGHT TO BURN ALL THE TIME. DEALER SAID MY PROBLEM, NOT GM'S. TRUCK HAS BEEN DEALER SERVICED AT ALL REQUIRED TIMES. I WOULD THINK A BRAKE SYSTEM FAILURE, EVEN IF A REDUNDENT SYSTEM, WOULD POSE A SAFETY ISSUE & REPAIRED BY GM. THE ABS SYSTEM WAS STANDARD EQUIPMENT, NOT OPTIONAL TO THE BUYER.*AK

ANTI LOCK BRAKE CONTROL MODULE SHORTED OUT REQUIRING STOPPING ON BUSY ROAD AND REMOVING A HIGH AMPERAGE FUSE FROM ROAD SIDE OF VEHICLE, AND LOSS OF ANTI LOCK BRAKE CAPACITY. VEHICLE HAS ONLY 34000 MILES. *AK

CONSUMER STATES THAT BRAKE ROTORS ARE WEARING. WHEN APPLYING THE BRAKES THE VEHICLE WILL HAVE A HEAVY VIBRATION AND EXTENDED STOPPING DISTANCE. DEALER NOTIFIED. *PH

CONSUMER STATES THAT WHEN TRYING TO APPLY THE ANTI LOCK BRAKES, THEY WILL LOCK UP CAUSING THE VEHICLE TO HAVE EXTENDED STOPPING DISTANCE. DEALER NOTIFIED. *PH

THE VEHICLE HEADLIGHTS ARE TO BRIGHT ON NORMAL SETTING, DISTRACTING VIEW FROM ON COMING TRAFFIC. DEALER NOTIFIED. *PH

ABS CONTROL MODULE FAILED ON 1999 GMC SIERRA 1500 4X4. GMC DEALERSHIP DIAGNOSED FAILED WIRING IN ABS PUMP RESULTING. I THINK THE ABS SYSTEM SHOULD BE ABSOLUTELY RELIABLE AS THIS IS AN IMPORTANT SAFETY FEATURE. *AK

CONSUMER STATES THAT STOPPING DISTANCE HAS INCREASED, AND THAT BRAKING CAPABILITY INTERMITTENTLY DOES NOT FUNCTION. DEALER DIAGNOSED THAT THE ANTI-LOCK BRAKE MODULE HAD FAILED.*AK

A COLLISION OCCURRED AS A RESULT OF COMPLETE STEERING FAILURE AND VIBRATIONS IN THE FRONT OF THE VEHICLE. THE VIBRATIONS OFTEN OCCURRED BETWEEN 55-70 MPH. THEY ORIGINATED IN THE FRONT END AND OFTEN TRANSFERRED INTO THE STEERING WHEEL. THIS CAUSED THE VEHICLE TO JERK ABRUPTLY, IN ONE DIRECTION OR ANOTHER. THE VIBRATIONS WERE SO EXTREME, IT CAUSED ABNORMAL WEAR AND FATIGUE ON THE TIRES, STEERING COMPONETS AND ETC. ONE FATALITY AS A RESULT. (BRENT MCQUEEN, INVESTIGATOR ON BEHALF OF CLIENT). *PH. THE INVESTIGATOR BELIEVED THE INCIDENT WAS RELATED TO RECALL (98V242000) HOWEVER THE VEHICLE WAS NOT INCLUDED IN THE RECALL.*JB

BRAKES DO NOT ALWAYS STOP TRUCK, VERY UNRELIABLE. *AK

WHEN THE ENGINE WAS TURNED OFF, THE ABS MODULE CONTINED TO RUN. AK *CB *JB

CONSUMER STATED THAT WHILE DRIVING AND WITHOUT WARNING ABS FAILED. DEALER NOTIFIED. *AK

WE OWN A 1999 GMC SIERRA PICKUP. THE ODOMETER AND SHIFT INDICATOR ARE THE LED TYPE. BOTH THE ODOMETER AND SHIFT INDICATOR HAVE SHORTED OUT AND THERE IS NO WAY TO TELL WHAT THE MILEAGE IS OR WHAT GEAR THE TRUCK IS IN. THIS HAS RESULTED IN TWO INCIDENTS WHERE PEOPLE WERE NEARLY RUN OVER BECAUSE THE DRIVER DID NOT KNOW IF THE TRUCK WAS IN FORWARD OR REVERSE. ALSO, ALTHOUGH THE ODOMETER MEASURES MILEAGE, WE CAN'T READ IT BECAUSE THE DISPLAY IS DARK. WE CONTACTED THE DEALER ABOUT GETTING THIS FIXED AND THEY INDICATED THE COST WAS $400 BUT THAT THEY HAD REPAIRED ONE OF THEIR OWN VEHICLES AND IT SHORTED OUT AGAIN TWO TIMES. THEY JUST PUT UP WITH IT. TO ME THAT SAYS THAT GMC HAS A PROBLEM WITH THIS COMPONENT AND THEY NEED TO TAKE CARE OF IT. THIS IS A SAFETY ISSUE. *JB

DRIVER'S SIDE SEAT TRACK BROKE WITHOUT FORCE, DRIVER WAS UNABLE TO POSITION THE SEAT. CAUSE UNKNOWN. *AK

PASSENGER SIDE WINDOW FAILS TO OPERATE. THIS WAS CAUSED BY A FAULTY MOTOR WHICH IS A COMMON PROBLEM.*AK

SON WAS DRIVING 99 GMC SIERRA TRUCK ON I-20 IN ARLINGTON, TX MONDAY, MAY 26TH WHEN HE BRAKED TO SLOW AND THE FRONT DRIVER SEAT SUDDENLY LURCHED FORWARD THROWING HIM INTO THE STEERING WHEEL CAUSING HIM TO LOSE CONTROL OF THE TRUCK. HE REGAINED CONTROL OF THE VEHICLE BUT WAS ALMOST REAR ENDED BY VEHICLE. SON AND FIANCEE WERE UNHURT AND NO DAMAGE WAS DONE. WHEN THEY WERE ABLE TO PULL OVER AND INVESTIGATE, THE FRONT DRIVER SEAT WOULD NOT LOCK IN PLACE. IT WOULD MOVE FORWARD AND BACKWARD WITHOUT LOCKING INTO PLACE. SON HAD TO BRACE HIS FOOT AGAINST THE DASH TO HOLD SEAT IN PLACE IN ABLE TO DRIVE THE VEHICLE HOME. SERIOUS INJURY COULD HAVE BEEN THE RESULT IF CONTROL OF THE VEHICLE HAD BEEN LOST. FEEL THIS IS A MANUFACTURERS DEFECT AND SERIOUS INJURY COULD RESULT IF THIS HAPPENED TO OTHERS OR MYSELF SINCE I DRIVE THE SAME IDENTICAL VEHICLE.

I STARTED MY TRUCK UP AND HEARD A VIBRATING NOISE AND THE ABS LIGHT CAME ON. WHEN I SHUT OFF MY TRUCK THE NOISE CONTINUED. I UNHOOKED THE BATTERY CABLE UNTIL I DETERMINED THE PROBLEM WAS THE ELECTO-HYDRAULIC CONTROL UNIT. I PULLED THE FUSE AND CHECKED WITH MY DEALER. THE SERVICE MANAGER ADVISED ME THAT BOTH PARTS OF THE UNIT (BPMV AND EBCM) USUALLY NEED TO BE REPLACED AT A COST OF APPROX. 1600.00 FOR PARTS ALONE. THIS TRUCK HAS ONLY 42,000 MILES ON IT. I ALSO CHANGED THE BRAKE FLUID AT 30,000 MILES IN ORDER TO AVOID THIS PROBLEM. I CONSIDER THE REPLACEMENT COST FOR THESE PARTS TO BE OUTRAGEOUS. THE FUSE CAN BE LEFT OUT AND THE VEHICLE CAN BE DRIVEN WITHOUT THE ANTI-LOCK FEATURE WORKING. I CONSIDER THIS A SAFETY DEFECT BECAUSE VERY FEW PEOPLE WILL PAY THIS PRICE TO HAVE THE ANTI-LOCKING FEATURE RESTORED. IN ADDITION, THE ABS AND BRAKE WARNING LIGHT COME ON AND CANNOT BE CLEARED WHEN DRIVEN WITH THE FUSE PULLED. THIS CAN CAUSE A DRIVER TO MISS OTHER PROBLEMS THAT WOULD BE INDICATED BY THE BRAKE WARNING LIGHT. *TT

ABS PUMP RUNS EVEN WITH KEY OFF! ONLY WAY TO STOP IT IS TO PULL FUSE. ABS AND BRAKE WARNING LIGHTS STAY ON ALL THE TIME. DID NOT INITIALLY NOTICE THE PROBLEM UNTIL I MADE A TIRE SCREECHING PANIC STOP. DEALERSHIP STATED NO RECALL. *NLM

ABS EBCM FAILED AND CONTINUES TO RUN WITH IGNITION OFF.

THE GAS TANK LEAKED. *JB

1999 GMC SIERRA ABS MOTOR STAYS ON CONTINUOUSLY. HAD TO PULL THE FUSE TO STOP IT. THE EBCM HAD TO BE REPLACED. THE REPAIR COST $1,105.00. THE TECHNICIAN SAID HE HAD SEEN IT BEFORE AND I SEE THAT MANY PEOPLE HAVE COMPLAINED OF THE SAME ISSUE ON THIS SITE. THE FAILURE OCCURRED AT 46,775 MILES WHICH IS ALSO CONSISTENT WITH OTHER DATA PRESENTED. GMC NEEDS TO DO A RECALL AND COMPENSATE US FOR THE EXPENSIVE REPAIRS. *JB

I AM HAVING TROUBLE WITH MY THROTTLE WHEN ATTEMPTING TO ACCELERATE FROM IDLE. IT FEELS AS THOUGH SOMETHING IS STICKING, THEN SUDDENLY RELEASING ONCE ENOUGH PRESSURE IS APPLIED TO THE ACCELERATOR PEDAL. THIS RESULTS IN THE VEHICLE LUNGING FORWARD EVERY TIME. *JB

I EXPERIENCED A HUMMING SOUND COMING FROM MY VEHICLE WHEN THE ENGINE WAS NOT RUNNING. I WENT TO A GM DEALER TO SEE WHAT THE PROBLEM WAS. THE SERVICE TECH SAID IMMEDIATELY THAT IT WAS BAD WIRING IN THE ABS MOTOR CAUSING IT TO RUN AT ALL TIMES. THIS WAS A REPAIR THAT NEEDED TO BE COMPLETED IMMEDIATELY BECAUSE THE MOTOR WAS RUNNING OFF OF MY BATTERY. THE DEALER SAID THAT HE HAS SEEN A FEW OF THESE VEHICLES WITH THE SAME PROBLEM. I PROCEEDED WITH THE REPAIR AND SPENT ABOUT 900.00. THIS IS NOT A RECALL, AT LEAST I AM NOT AWARE OF IT, AND SHOULD BE INVESTIGATED. *JB

CONSUMER INDICATED THAT THEIR VEHICLE'S STEERING IS EXPERIENCING THE SAME DEFECT AS STATED IN RECALL 98 V 242 000, BUT VEHICLE'S VIN NUMBER IS NOT INCLUDED. *NLM

ABS MODULE FAILURE. MY TRUCK HAD PROBLEMS WITH THE ABS ACTIVATING SINCE IT WAS NEW. JUST RECENTLY I HAVE JOINED THE RANKS OF OWNERS WITH CONTINUOUSLY RUNNING MODULES. WHEN I FOUND OUT IT WOULD COST AT LEAST A GRAND TO FIX, I PULLED THE FUSE. *JB

ABS CONTROL MODULE FAILED. AFTER TURNING OFF VEHICLE, ABS MODULE CONTINUED TO RUN. HAD TO DISCONNECT ABS MODULE TO STOP IT. *JB

THE ACCELERATOR PEDAL HAD BECOME STUCK. THE CONSUMER HAD TO PUMP THE PEDAL IN ORDER FOR IT TO RELEASE, WHICH THEN CAUSED THE VEHICLE TO SURGE FORWARD. *JB *SCC

THE ANTI-LOCK BRAKE SYSTEM FAILED, WHICH CAUSED THE VEHICLE TO EXPERIENCE EXTENDED STOPPING DISTANCE.*JB

WHILE DRIVING THE ABS LIGHT COME ON AND AND STAYED ON. I HEARD A LOUD NOISE COMING FROM UNDERNEATH THE DRIVER SIDE DOOR. THE NOISE CONTINUED AFTER THE VEHICLE WAS TURNED OFF AND IT WONT STOP. I PULL OUT THE ABS FUSE AND THE NOISE STOPED. I TOOK THE TRUCK TO THE DEALER AND HE SAID WHAT IT WAS. THE ABS CONTROL MODULE WAS SHORTED AND THE MOTOR WONT STOP. IT COST ME $900.00 DOLLARS TO REPAIR THIS PROBLEM AFTER I TALKED OUT THE SERVICE PERSON, I THINK THIS IS WAY TO EXPENSIVE AND TO SOON TO FAILED, FOR WHAT I HAVE FOUND OUT GMC NEEDS TO ISSUE A RECALL ON THIS SYSTEM. RESPECTFULLY SUBMITED. JUAN PINEDO.

THE VEHICLES ABS MOTOR CONTINUED TO RUN AFTER THE VEHICLE WAS TURNED OFF. PH

BRAKE FAILURE. AFTER SLOWING OR STOPPING AT AN INTERSECTION OR PULLING INTO A PARKING SPOT, AND AFTER RELEASING THE BRAKES, AT REAPPLICATION THE BRAKE DOES NOT RESPOND. THE PEDAL DOES NOT RESPOND, NO DEPRESSION TAKES PLACE -- IT FEELS LIKE A ROCK! -- AND THE TRUCK DOES NOT STOP. AFTER REPEATED ATTEMPTS, THE BRAKE WILL EVENTUALLY RESPOND, IN THE MEANTIME IT IS A HAZARDOUS SITUATION.

GAS PEDAL STICKS OFF IDLE. CAUSES VEHICLE TO LUNGE WHEN STARTING OUT. IS MOST LIKELY SERVICE BULLETIN 00-06-04-007A. CONTACTED GM, THEY WILL NOT PAY FOR PART BECAUSE I AM OUT OF WARRENTY. THIS IS A SAFETY ISSUE AND SHOULD BE A RECALL.

ELECTRICAL FIRE IN DRIVER'S SIDE DOOR OF 1999 GMC SIERRA 1500 PICKUP. HEAVY SMOKE DAMAGE, DOOR PANEL DESTROYED, TRIM AROUND THE DOOR DESSTROYED AND SMALL AREA OF CARPET BURNT BY DOOR

WHILE DRIVING VEHICLE ABS AND PARKING BRAKE LIGHT ILLUMINATED. WHEN THIS HAPPENED IT CAUSED BRAKES TO LOCK UP. COULD BE VERY DANGEROUS IN A SUDDEN STOP. PLEASE PROVIDE ANY FURTHER INFORMATION. TS. *AK

THE RIGHT (PASSENGER) SIDE WINDOW WILL NOT GO UP. I HAD LOWERED THE WINDOW PARTIALLY FOR VENTILATION BUT WHEN I TRIED TO RAISE THE WINDOW, IT DID NOT MOVE AND YOU COULD HEAR THE CABLE BINDING INSIDE THE DOOR.

THE EBCM (ELECTRONIC BRAKE CONTROL MODULE) HAS FAILED ON MY 1999 GMC SIERRA. IT HAS LESS THAN 40000 MILES ON IT, AND FROM INFORMATION OBTAINED ONLINE, THIS APPEARS TO BE QUITE A COMMONPLACE EVENT ON THESE VEHICLES. THE ABS LIGHT COMES ON, AND THE PUMP WILL RUN EVEN WITH THE IGNITION KEY REMOVED.

WHILE DRIVING AT A LOW SPEED BRAKE PEDAL FROZE AND WHEEL CONTINUED TURNING. THIS CAUSED VEHICLE TO HAVE EXTENDED STOPPING DISTANCE. DEALER NOTIFIED. PLEASE PROVIDE ADDITIONAL INFORMATION. PH

UPON RESTARTING THE VEHICLE THERE WAS NO POWER STEERING. THE VEHICLE WAS DRIVEN AND TURNED OFF PRIOR TO FAILURE. THIS WAS CAUSED BY THE PULLEY BREAKING. *AK *SC *JB

CONSUMER STATED THE ANTI-LOCK BRAKE SYSTEM MODULE WAS ENGAGING UNNECESSARILY WHILE DRIVING AND CONTINUED TO RUN WHEN VEHICLE WAS TURNED OFF. CONSUMER HAD TO PULL ABS FUSE TO DISENGAGE, THIS RESULTED IN LOSS OF ABS FUNCTIONALITY. *JB

THE ABS MOTOR CONTINUES TO RUN AFTER SHUTTING THE VEHICLE OFF. THIS CAUSES THE BATTERY TO RUN DOWN MAKING THE VEHICLE INOPERATIVE. THE ABS SYSTEM NO LONGER IS OPERATIVE. THE COST TO REPAIR IS APPROXIMATELY $1000. TS

1999 GMC SIERRA 4X2, AUTO, SHORT BED. THE ABS MOTOR CAME ON AN STAYED ON. I COULD NOT GET THE MOTOR TO SHUT DOWN UNTIL I EITHER PULLED THE ABS FUSE, OR DISCONNECTED THE MOTOR UNDER THE TRUCK. I HAVE TALKED TO THE LOCAL DEALRER AND HE HAS HAD SEVERAL ISSUES LIKE THIS AS WELL AS MANY THAT ARE DOUCUMENTED ON THE NHTSA WEBSITE. DUE TO THE NUMEROUS COMPLAINTS AND SEFVERITY OF THIS ISSUE I THINK THAT GMC NEEDS TO ISSUE A RECALL ON THIS SYSTEM. RESPECTFULLY SUBMITTED, GARY EASLEY

I EXPERIENCED A SUDDEN ONSET OF A HISSING NOISE COMING FROM UNDER THE DASHBOARD. THE NOISE ONLY STARTS ABOVE 1400 RPM AND WHEN WARM. I HAVE TAKEN IT TO 2 GMC DEALERS AND 1 INDEPENDENT SERVICE SHOP. ALL HAVE STATED THAT THE NOISE IS WATER GOING THROUGH THE HEATER CORE. 1 DEALER SAID THAT THE COOLANT MUST HAVE BROKEN DOWN AND GELLED OR SCALED INTO THE HEATER CORE; THEREFORE, IT MUST BE REPLACED. GMC OWNERS MANUAL STATES CHANGE COOLANT AT 150000 MILE OR 5 YEARS, IF SO, WHY DID THE COOLANT BREAK DOWN? THIS APPEARS TO BE A MAJOR ISSUE AND I HAVE READ OF SIMILAR CASES. PLEASE HELP. DT

ABS CONTROL MODULE FAILED. MODULE CONTINUED TO RUN AFTER VEHICLE WAS TURNED OFF. $1000 TO REPAIR. NO RECALL INSPITE OF NUMEROUS COMPLAINTS TO NHTSA. DT

CONSUMER STATED THAT AT 32K MILES EXPERIENCED INTERMITTENT STICKING OF THE THROTTLE. DEALER INSPECTED AND REPAIRED. AT 50K MILES THE PROBLEM REOCURRED. TS *TT
