2003 GMC SIERRA Power Train Problems

I WAS PARKED ON A SLOPED DRIVEWAY (ABOUT 10 - 15 DEGREES). I STARTED THE ENGINE, STEPPED ON THE BRAKE PEDAL AND TOOK THE CAR OUT OF PARK INTO DRIVE. BRAKE PEDAL WAS NORMAL. I STARTED TO ROLL FORWARD AND WHEN I PUSHED THE BRAKE PEDAL THE CAR DID NOT SLOW. I SLAMMED THE BRAKE PEDAL AND IT WENT ALL THE WAY TO THE FLOOR. AT THIS POINT I WENT OFF THE END OF THE DRIVEWAY ONTO A 45 DEGREE DOWNWARD SLOPED LAWN; THEN INTO A WOODED AREA AT THE TOP OF A RAVINE. I SLAMMED INTO A TREE. THE CAR WAS JUDGED A TOTAL LOSS BY MY INSURANCE COMPANY. I DID NOT GET A BRAKE WARNING LIGHT. THE AIRBAGS DID NOT DEPLOY. THE CAR WAS SERVICED AT A UNION PARK GMC (WILMINGTON, DE) TWO DAYS PRIOR. INCLUDING BRAKE INSPECTION. CAUSE OF BRAKE FAILURE WAS DETERMINED TO BE RUPTURED BRAKE LINE. BOTH FRONT AND REAR BRAKES WERE FAILED. *TR

4 WHEEL DRIVE TRANSMISSION WILL SHIFT FROM 2 WHEEL TO 4 WHEEL LOW WHILE DRIVING. SOMETIMES IT WILL SHIFT TO NEUTRAL. THIS CAN BE VERY DANGEROUS. YOU BASICALLY DON'T HAVE THE CONTROL OF THE VEHICLE THAT YOU THOUGHT YOU HAD. *JB

THE TRANSMISSION CLUNKS WHEN SHIFTING FROM 2ND - 3 RD AND AT TIMES THE ENGINE WILL REV AND FINALLY IT WILL TAKE OFF, THIS HAS CAUSED AN ISSUE WHEN GOING THROUGH AN INTERSECTION. THE DEALERSHIP ATTEMPTED FOUR REPAIRS AND IT IS NOT FIXED. THE ISSUE STARTED WHEN THE VEHICLE HAD 6K MILES ON IT AND IT IS GETTING WORSE. THE SPEEDOMETER IS SPORADIC IN THAT IT WILL SHOW SPEED REDUCTION/INCREASE IN SEGMENTS - AS IF IT WERE STICKING. THE ERRONEOUS SPEED INDICATION CAUSES AN ISSUE WHEN GOING TOO SLOW OR TOO FAST IN TRAFFIC. *NM

I HAVE BEEN HAVING TROUBLE WITH MY FOUR WHEEL DRIVE. THE ENGINE SEEMS TO BOG DOWN LIKE I AM PULLING SOMETHING. TOOK IT IN TO GET LOOKED AT AND THE REPAIRMAN HAD TO REPLACE A PART SAYING THAT IT WAS AUTOMATICALLY KICKING IN AND OUT. HE FIXED IT AND IT WAS FINE FOR ABOUT 6 MONTHS AND NOW IT IS DOING IT AGAIN. YOU CAN EVEN HEAR IT IN THE ENGINE, IT SOUNDS LIKE IT DOWN SHIFTS TO PULL SOMETHING. *NM

TRANSMISSION: BEEN FIXED 3 TIMES AND FINALLY REPLACED A/C: REPAIRED ONCE FRONT END-STEERING: REPAIRED 3 TIMES AND STILL NOT FIXED. *JB

TRANSMISSION HAS "CLUNKING" NOISE WHEN VEHICLE SHIFTS FROM SECOND TO THIRD GEAR WHEN STARTING AND DOWN SHIFTING WHEN STOPPING. THE NOISE STARTED AT APPROXIMATELY 4000 MILES AND CONTINUES TO PROGRESSIVELY GET LOUDER AS THE VEHICLE CONTINUES TO BE DRIVEN. THE TRANSMISSION HAS NOT FAILED TO OPERATE AT THIS TIME BUT EXPECT IT TO FAIL SOMETIME IN THE NEAR FUTURE. *JB

I DRIVE A 2003 GMC SIERRA AND THERE IS A TRANSMISSION PROBLEM IT MAKES THE DRIVING VERY DANGEROUS ESPECIALLY AT HIGHWAY. SPEED. THE VEHICLE CANNOT STAY STRAIT IT EITHER PULLS TO THE LEFT OR TO THE RIGHT. THE FEEL OF THE VEHICLE ISN'T RIGHT LIKE IF ITS DOG TRACKING. THERE ARE CLONKING AND TICKING SOUNDS COMING FROM THE TRANSMISSION JUST FROM SHIFTING FROM DRIVE TO REVERSE,REVERSE TO DRIVE...PARK. WHILE DRIVING WHEN ENGAGING THE PASSING GEAR SOMETIMES YOU HEAR THAT CLONKING SOUND LIKE IF THERE WAS A SLACK IN THE TRANSMISSION. I HAD THIS VEHICLE SINCE JULY 2004 AND SINCE THEN I'VE BEEN TO THE DEALERSHIP A NUMBER OF TIMES EVERYTIME THEY SAID THAT EVERYTHING WAS OK AND SHOWED ME PAPERWORK STATING FROM GM CANADA THAT CLONKING, TICKING ETC. ETC. WERE NORMAL OPERATION OF THE TRANSMISSION. IT CANT BE CAUSE I HAD A 2001 GMC TRUCK WHICH I TRADED FOR, THAT DROVE LIKE A TRUCK THIS ONE I HAVE NOW DRIVES LIKE A TANK. EVERY HOLE OR CRACK IN THE ROAD I CAN FEEL WHEN I HIT A SMALL HOLE OR A DIP IN THE PAVE THE VEHICLE WANTS TO DOG TRACK MOST OF THE TIME THE TRUCK PULLS TO THE LEFT, WHEN IT DOES THERE IS A SLIGHT VIBRATION YOU CAN FEEL FROM THE ACCELERATOR OR THE BRAKE. THIS VEHICLE I FIND IS A ACCIDENT WAITING TO HAPPEN. ITS A BIG VEHICLE AND TO SWERVE SIDE TO SIDE SCARES OTHER VEHICLES ON THE HIGHWAY, WHICH PUTS EVERYBODY AT RISK EVERYTIME I'M ON THE ROAD. FROM ALL THESE COMPLAINTS I DID TO GM STILL TODAY THEY TELL ME AND SHOW ME PAPERWORK FROM GM TECH LINE. STATING THAT EVERYTHING IS NORMAL AND NO WORK FROM THERE PART SHOULD BE DONE ON THIS TRUCK. IT'S LIKE IF GM HAS PEOPLE WORKING ON THESE STATEMENTS JUST TO COVER THEMSELVES FROM HAVING TO REPAIR OR CHANGE PARTS IN ORDER TO SAVE MONEY IN WHICH I WOULDN'T DOUGHT. IF YOU CAN HELP ME PLEASE. LET ME KNOW CAUSE THIS IS A VERY SERIOUS MATTER WHICH I WOULD LIKE TO FIX BEFORE I GET INTO AN ACCIDENT. I BELIEVE THERE IS A CONTROVERSY INTO ALL OF THIS. *NM

AFTER DRIVING OVER ABOUT 40 MILES AT HIGHWAY SPEED THE TRANSMISSION WILL BEGIN SLIPPPING IN OD. RPM SLOWLY CLIMBS TO ABOUT 3200 (NORMALLY 2100 AT HIGHWAY SPEED) WITH NO CHANGE IN VEHICLE SPEED, AND EVENTUALLY THE 'TRANSMISSION HIGH TEMPERATURE' WARNING APPEARS ON THE DASHBOARD DISPLAY. SHIFTING TO NEUTRAL AND ALLOWING THE ENGINE TO IDLE FOR ABOUT 20 SECONDS AND THEN RETURNING TO DRIVE WILL TEMPORARILY CLEAR THE PROBLEM, BUT IT SOMETIMES RETURNS.*AK

I PURCHASED MY 2003 GMC SIERRA Z71 IN AUG. 2003. IN DECEMBER 2003, WHILE PULLING A TRAVEL TRAILOR, THE SERVICE 4-WD LIGHT CAME ON AND THE TRUCK FELT AS IF IT HAD BEEN SHIFTED INTO NEUTRAL.I MANAGED TO GET THE TRUCK TO THE SIDE OF THE ROAD AND READ THE OWNERS MANUAL CONCERNING THE LIGHT. I TURNED THE TRUCK OFF AS THE BOOK SAID AND THEN RESTARTED. THE LIGHT STAYED ON, BUT THE TRUCK DID GO IN GEAR. SINCE THIS TIME, WHEN I PULL THE TRAILOR FOR A LONG PERIOD OF TIME, THE TRUCK WILL AGAIN FEEL AS IF IT IS IN NEUTRAL. I HAVE TO PUT THE TRUCK INTO 2ND OR 1ST GEAR TO GET THE TRANSMISSION TO ENGAGE. THE 4WD LIGHT COMES ON WITH OR WITHOUT THE TRAILOR HOOKED UP AND HAS BEEN CHECKED SEVERAL TIMES BY THE DEALER. THEY HAVE REPLACED THE SWITCH BUT THIS HAS NOT CORRECTED THE PROBLEM. THE TRANSMISSION SHIFTS SO HARD IT FEELS AS IF THE BACK END OF THE TRUCK WILL FALL OUT. I WAS TOLD THIS IS NORMAL OPERATION. SOMETHING NEEDS TO BE DONE TO CORRECT THIS PROBLEM AS THIS IS A HUGE SAFETY ISSUE. NO ONE CAN FEEL COMFORTABLE DRIVING DOWN A ROAD AND NEVER KNOWING IF YOU WILL BE HIT FROM BEHIND DUE TO THIS TRUCK STALLING FOR NO REASON. *AK

I HAVE A 2003 GMC SIERRA 1500. AT 1300 MILES, I LOST A FITTING THAT CONNECTS THE TRANSMISSION LINE TO THE RADIATOR FOR THE TRANNY COOLER AND THE TRANSMISSION WAS DESTROYED. A REBUILT TRANSMISSION WAS PUT IN MY PICKUP. I NOW HAVE 32000 MILES ON IT AND THE TRANSMISSION SEEMS TO "DOUBLE" SHIFT BETWEEN 2ND AND 3RD GEAR. I'VE HAD MY TRUCK IN THE SHOP 5 TIMES TO DIAGNOSE THIS PROBLEM. THE DEALERSHIP CANNOT REPRODUCE/FIND THE ISSUE. THE PRESSURE CONTROL SOLENOID WAS REPLACED ABOUT 4 DAYS AGO. THE TRANSMISSION IS STILL ACTING UP.

ON FEBRUARY 18, 2003 I PURCHASED A NEW 2003 TRUCK THE TRUCK CAME WITH THE SERVICE LIGHT ON. WHEN DRIVING THE 4X4 WHEEL LIGHT WOULD COME ON AS IF THE TRUCK WAS IN 4 WHEEL DRIVE. THE LIGHT WOULD GO OFF AFTER STOPPING AND SHUTING THE TRUCK OFF FOR AT LEAST 15 MINUTES. I WENT TO THE DEALER AND THEY SAID THERE WAS NO FIX AT THIS TIME AND THEY GAVE ME A SERVICE BULLETIN, FILE IN SECTION:4-DRIVELINE AXLE BULLETIN NO:03-04-21-001 DATE: FEBRUARY, 2003. I WAS TOLD THAT IF I WAS WORRIED ABOUT THE 4X4 ENGAGING ON ITS OWN WHILE DRIVING THE ONLY THING THEY COULD DO WAS TO DISENGAGE THE 4X4 WHEEL DRIVE AT THIS TIME.I NEED TO HAVE THE USE OF THE 4X4 WHEEL DRIVE AS I OWN A LARGE CONCRETE CONSTRUCTION COMPANY AND USE MY TRUCK ALL DAY LONG ON JOBSITES. I LEFT THE DEALER NOT KNOWING WHAT TO DO. I WAS WORRIED ABOUT DAMAGING THE 4X4 UNIT EVEN MORE ON MY NEW TRUCK. SO TWO WEEKS LATER I WAS TIRED OF WORRYING, SO I TOOK THE TRUCK BACK TO THE DEALER AND THEY DISENGAGED THE 4 WHEEL DRIVE. THE SERVICE 4X4 WHEEEL LIGHT IS STILL ON AT THIS TIME. I ALSO FILED A COMPLAINT WITH GMC ON 3/27/03 #1-85090755. I HAVE NOT HEARD FRON THE DEALER IN ONE MONTH.

ON MAY 31ST, THE REAR END DIFFERENTIAL ASSEMBLY EXPLODED SENDING THE PINON THRU THE HOUSING AND THE REAR AXLE CAUGHT ON FIRE. THE TRUCK WAS IN THE SHOP (PERRY CHEVEROLET, INC., COLUMBIA, MO)UNTIL 6-9-03. WHEN I ARRIVED IN BOZEMAN, MT ON 7-2-03 I WAS HAVING PROBLEMS WITH THE WIRING. THERE WAS A FIRE WHEN I PLUGGED THE RV ELECTRICAL PLUG INTO THE TRUCK'S TRAILER PLUG. THERE WAS ALSO A BLOWN REAR TAIL LIGHT BULB. IN BOZMAN, THEY REPLACED THE COMPLETE WIRING HARNESS, THE TOW RECEPTACLE AND 2 FUSE KITS. IT WAS THE OPINION OF THE SHOP IN BOZEMAN (J.C.BILLION, GMC) THAT THE WIRING DAMAGE WAS PART OF THE ORIGINAL FIRE AND DIFFERENTIAL ASSEMBLY DAMAGE. ALTHOUGH GMC PAID FOR MY OUT OF POCKET EXPENSES AND FOR THE WARANTY WORK, I AM LEFT TO WONDER WHAT WILL HAPPEN NEXT AND JUST HOW SAFE AM I GOING TO BE IN THIS TRUCK? I SELECTED A TRUCK BIGGER THAN WHAT I NEEDED AT THE CURRENT TIME, THINKING THAT IF I REPLACED MY TRAVEL TRAILER IN THE FUTURE, I WOULD NOT HAVE TO TRADE TRUCKS ALSO.

I OWN A 2003 GMC SIERRA 1500 Z71 OFF ROAD TRUCK. I'VE HAD IT IN THE SHOP FOUR TIMES NOW DUE TO THE SAME PROBLEM. THE PROBLEM CONSISTS OF EXCESSIVE PLAY/BACKLASH IN THE REAREND/DIFFERENTIAL ACCORDING TO THE DEALER. THIS EXCESSIVE PLAY/BACKLASH IS CAUSING THE TRUCK TO JERK AFTER SHIFTING FROM FIRST TO SECOND AND SECOND TO THIRD GEARS. THE DEALER AND MANUFACTURER SAY THIS IS NORMAL ACCORDING TO GM SPECS. AT ONE POINT, WHILE SITTING AT A TRAFFIC LIGHT, I PROCEEDED TO ACCELERATE AFTER THE LIGHT TURNED GREEN AND THE TRUCK DIDN'T GO ANYWHERE, BUT AFTER A FEW SECONDS THE TRUCK SLAMMED INTO GEAR AND SPUN THE REAR TIRES. THIS PROBLEM SEEMS TO HAVE BEEN CORRECTED AFTER REPLACING THE TRANSMISSION CONTROL SOLENOID FOR NOW, BUT THE CONSTANT JERKING OF THE REAREND/DIFFERENTIAL SEEMS TO BE WORSENING. WHEN DISCUSSING THIS PROBLEM WITH THE DEALERS SERVICE MANGER AND NOW FINALLY WITH THE GENERAL MANGER, THEY STILL SAY THIS IS NORMAL AND HAS BEEN FOR ALL 2000 THROUGH 2004 GMC SIERRA'S. THAT'S INTERESTING, BECAUSE I OWNED TWO 2000 GMC TRUCKS IN THE PAST AND NEITHER ONE OF THEM EXPERIENCED THESE PROBLEMS.

WHEN THE 4 WHEEL DRIVE LIGHT ILLUMINATES ON THE DASHBOARD VEHICLE FAILS TO ACCELERATE. THIS IS CAUSED BY THE TRANSFER CASE ENCODER MOTOR LOCKING IN 4 WHEEL DRIVE. DEALERSHIP REPLACED THE PART, BUT CAUSE OF THE FAILURE IS UNDETERMINED.*AK

WHILE DRIVING AT ANY SPEED VEHICLE HAS A PROBLEM SHIFTING INTO A GEAR. WHEN THE GEAR IS CHANGING THERE IS A HARD THUMP/A BRIEF HESITATION BEFORE THE GEAR ACTUALLY GOES IN TO THE PROPER POSITION.

I OWN A 2003 GMC SEIRRA 4X4 SLE (EXT) CAB AND THE TRANSMISSION IS VERY JERKY BETWEEN FIRST AND SECOND GEAR AND BETWEEN SECOND AND THIRD GEAR ALSO , BUT AT TIMES THERE IS A CLUCK NOISE BETWEEN SECOND AND THIRD GEAR. WHICH SOUNDS LIKE A UNIVERSAL JOINT THAT IS BAD.FIRST TIME I TOOK IT TO THE DEALER THEY SAID THEY COULDN'T REPRODUCE THE PROBLEM. SECOND TIME THEY CHANGE THE PRESSURE CONTROL SOLENOID IN THETHE VALVE BODY, FILTER, AND FLUID IN TRANSMISSION. IT WORKED GREAT FOR @ TWO WEEKS AND NOW IT'S BACK. THERE IS A PROBLEM HERE . TWO FRIENDS AT WORK HAVE THE SAME PROBLEMS WITH THERE 2003 GMC'S AND CHEVY'S TRUCKS.*AK

I HAVE A 2003 GMC SIERRA SLT EXT. CAB Z71 (4X4), THE 4-WHEEL DRIVE IS NOT WORKING, NO LIGHTS SHOW UP ON THE BUTTONS. THE DEALER HAS ATTEMPTED TO REPLACE THE 4WD SWITCH, THIS DID NOT FIX THE PROBLEM, THEY STILL HAVE THE TRUCK. THE TRUCK IS LESS THAN A YEAR OLD AND HAS 20,700MI. THERE ARE SERVICE BULLITENS FOR THE PROBLEM, BUT THERE IS NO PERMANENT FIX. WHY SELL A 4WD PRODUCT IF THE 4WD WILL NOT WORK?

I OWN A 2003 CMG 1500 4X4 WHEN I HAD 300 MILES ON VEHICHLE I NOTICED A VIBRATION IN THE DRIVETRAIN. I TOOK TO DEALER, THEY ADJUSTED TIRE AIR PRESSURE. 2ND TIME IN THEY CHANGED BEARING IN FRONT DIFFERENTIAL, 3RD TIME IN THEY CHANGED FRONT DIFFERENTIAL CARRIER, THIS GOT RID OF VIBRATION, I STILL HAVE A CONCERN THAT THE CARRIER COME AS A SHELL SO IT STILL HAS ORIGINAL RING AND PINION. DON'T NO IF THIS WILL CREATE A PROBLEM LATER OR NOT BUT GEAR PATERN MUST HAVE CHANGED. *AK

WHEN VEHICLE WAS STOPPED ON AN INCLINE WITH GEAR PLACED IN PARK BEFORE ENGAGING PARKING BRAKE THE TRANSMISSION LOCKED IN PARK. IN ORDER TO UNLOCK IT THE CONSUMER HAD TO HAVE THE TOW TRUCK PULL THE VEHICLE IN ORDER TO UNLOCK IT. THE MANUFACTURER ADVISED THAT THIS WAS NORMAL OPERATION. TRUCK IS A 2003 GMC 1/2TON 4-WHEEL DRIVE PICKUP. *NLM

WHILE DRIVING THE FOURTH GEAR OF THE AUTOMATIC TRANSMISSION JUMPED. THE DEALER INSPECTED THE VEHICLE BUT COULD NOT DUPLICATE OR CORRECT THE PROBLEM. *NLM
