2000 GMC SIERRA Complaints

ON 12/13/99 WHEN SLOWING DOWN TO MAKE A LEFT TURN, THE TOURQUE CONVERTER LOCKED UP AND STALLED THE TRUCK IN MIDDLE OF TRAFFIC WHILE CROSSING THE LEFT LANE. WITH DIFFICULTY, TRUNED THE WHEEL BACK TO THE RIGHT AND PULL OFF THE ROAD AND SHIFTED INTO PARK AND RESTARTED THE TRUCK. LUCKLY THERE WAS VERY LITTLE ON COMING TRAFFIC. ON 2/11/00 WHILE COMING INTO A ROLLING RIGHT HAND TURN AND GOING ABOUT 15 MPH, I STARTED TO BRAKE AND THE TOURQUE CONVERTED AGAIN LOCKED UP AND THE ENGINE STALLED. AGAIN WITH DIFFICULTY I WAS ABLE TO STEER INTO THE CORNER AND MAKE THE CORNER. AS THE TRUCK WAS FREE ROLLING IT JUST STARTED ITSELF AND IT CONTIUNED ON, ALMOST CRACHED INTO TWO CARS WAITING AT THE STOP SIGN. IF MY WIFE WAS DRIVING THERE WOULD HAVE BEEN A COLLISION. IN OCTOBER WHEN WAITING FOR A TRAFFIC LIGHT TO CHANGE, I ACCELLERATED AND TRUCK DIDN'T MOVE. I STEPPED ON THE BRAKE SHIFTED TO PARK AND THEN BACK TO DRIVE AND IT FINALLY WENT INTO GEAR AND MOVED. HAVE BEEN BACK TO THE DEALER TWICE WITH TOURQUE CONVERTER CONCERNS WITH NO SOLUTIONS. GM HAS A TRANSMISSION PROBLEM WITH THERE 4L60E TRANSMISSIONS. MY 1998 GMC JIMMY HAS BEEN REPLACED AT 19000 MILES. AM VERY WORRIED THAT THIS WILL HAPPEN AT ANY TIME WHEN NOT READY AND AN ACCEDENT WILL HAPPEN. *AK

NO DEPLOYMENT OF PASSENGER AND DRIVERS AIR BAGS DURING A FRONTAL COLLISION WITH A TREE RESULTED IN INJURIES. PASSENGER SUSTAINED CHEST, KNEES, NECK, AND HEAD TRAUMA WHILE DRIVER SUFFERED SUBDURAL HEMOTOMA, INJURY TO BOTH KNEES AND WRIST AS WELL AS MOUTH, THROAT, FACE, HAED AND RIBS. NLM

VEHICLE EXPERIENCE VIBRATION WHILE DRIVING OVER 30 MPH, CAUSING STEERING TO SHAKE VIOLENTLY. VIBRATION WILL FADE AFTER SPEEDS OF 50 MPH. DEALER HAS CHECKED TIRES/ WHEELS, CANNOT DETERMINE CAUSE. *AK *YC

BRAKE SYSTEM: WHILE DRIVING ON AVENUE AT 35-40MPH, I CROSSED A RAILROAD CROSSING WHILE BRAKING AND BRAKE PEDAL APPEARED TO GO TO THE POINT OF LEAST RESISTANCE, OR NEAR THE FLOOR BOARD. ALSO, WHILE STOPPED AT INTERSECTIONS, NOTICED BRAKE PEDAL VERY SLOWLY MOVING TO THE FLOOR WHILE FOOT ON BRAKE PEDAL. IMMEDIATELY TOOK TRUCK TO THE DEALER SERVICE DEPT. AND THE SERVICE DEPT. DIAGNOSED IT AS A LEAKING MASTER CYLINDER. THE MASTER CYLINDER WAS REPLACED HOWEVER I STILL NOTICE BRAKE PEDAL SEEKING POINT OF LEAST RESISTANCE WHILE CROSSING RAILROAD CROSSINGS AND DIPS/MODERATE BUMPS IN THE ROAD. I FEEL THAT THIS IS A SAFETY ISSUE DUE TO THE FACT THAT I BOUGHT THIS TRUCK AS A FAMILY TRUCK AND IT CARRIES MY CHILDREN ON A REGULAR BASIS. I FEEL THAT MASTER CYLINDER SHOULD NOT HAVE LEAKED AT 822 MILES. OTHER ISSUE>>> HIGHWAY SPEED VIBRATIONS: TRUCK HAS HAD A PERSISTENT HIGHWAY SPEED VIBRATION (40-45 MPH AND 60-70 MPH). THE TRUCK WAS SERVICED FOR THIS PROBLEM ON SEPT. 27 AND OCT. 5. SEPT. 27 THEY BALANCED THE WHEELS. ON OCT. 5, THEY BALANCED THE WHEELS AGAIN AND SUGGESTED THAT THE WHEEL WEIGHTS ARE "COMING OFF" CAUSING UNBALANCED TIRES. WHEEL WEIGHTS HAVE REMAINED INTACT AS OF THIS DATE BUT VIBRATION STILL EXIST. THE VIBRATION FEELS LIKE IT STARTS AT THE REAR OF THE TRUCK AND MIGRATES THROUGH THE TRUCK TO THE STEERING COLUMN AND WHEEL WHICH ON OCCASION HAS EXHIBITED MODERATE TO HEAVY SHAKING INCLUDING SEATS AND DASH. WHILE IN TURNS AT TIMES AND GOING OVER BUMPS, STEERING WHEEL SHAKES GIVING THE SENSE OF NOT IN CONTROL. I FEEL THIS IS A SAFETY ISSUE SINCE VEHICLE SHAKES AND VIBRATES WHILE AT HIGHWAY SPEEDS AND SOMETHING SHOULD BE DONE TO CORRECT. THE GM FACTORY REP. WOULD LIKE TO CHANGE THE TIRES TO THE SAME BRAND, GOODYEAR WRANGLERS, HOWEVER I SUGGESTED TO HIM THAT THE TRUCK WAS IN FOR VIBRATION TWICE AND I SUGGESTED SWAPPING TIRES/WHEELS TO SEE IF THIS WOULD SOLVE PROBLEM AND THEY INDICATED THEY DID SWAP BUT IT DID NOT SOLVE PROBLEM. THIS VEHICLE IS NOT SAFE.

VEHICLE WENT OUT OF CONTROL AND HIT THE MEDIAN CAUSING INJURY TO DRIVER AND PASSENGERS BECAUSE OF BRAKE AND STEERING MECHANISM FAILURE. YH

WHILE DRIVING DOWN A DIRT HILL AT 3 MPH APPLIED BRAKES, AND THE VEHICLE FREE WHEELED DOWN A HILL AT 40 MPH DUE TO THE ABS SYSTEM FAILURE. ALSO, FRAME IS BENT.*AK

ON LOOSE DIRT WHILE TRAVELING DOWN HILL BRAKES LET GO. THE BOTTOM OF THE TRUCK HIT THE BOTTOM OF THE HILL, BENDING THE FRONT FRAME RAILS AND FRONT CROSS MEMEBER. DRIVER WAS TRAVELING ABOUT 30-40 MPH WHEN THIS HAPPENED. THE PROBLEM HAS BEEN REPORTED TO THE DEALERSHIP. PLEASE PROVIDE FURTHER INFORMATION. *AK
