2006 GMC SIERRA 1500 CREW CAB. ONLY A YEAR OLD AND WITH LESS THAN 15,000 MILES, THE RIGHT TAIL LIGHT ASSEMBLY FELL OFF. THERE HAD BEEN NO ACCIDENT, IMPACT OR ABUSE. THE CAUSE WAS THE BREAKING OF THE TWO PLASTIC THREADS IN THE TAILLIGHT ASSEMBLY. THESE FLIMSY, WEAK, THREADED PARTS ARE ALL THAT HOLD THE TAILLIGHT ON AND ARE CLEARLY INADEQUATE FOR THE LOAD. THIS SHOULD NOT BE A WEAR AND TEAR ITEM; IT IS A DESIGN DEFECT. THERE SHOULD BE SOME METAL HOLDING THE SCREWS, NOT THIN PLASTIC. *TR

VEHICLE- 2006 GMC SIERRA 2500HD 4X4 DURAMAX/ALLISON THERE IS A VERY NOTICEABLE CLUNK/LOOSENESS IN THE STEERING. I HAVE GREASED/LUBRICATED THE WHOLE STEERING MECHANISM WITH NO REDUCTION IN THE PROBLEM. MY FEAR IS THE LOOSENESS WILL RESULT IN A COMPLETE FAILURE OR LOSS OF STEERING. PRIOR TO THAT I FEAR POOR DRIVING/MANEUVER ABILITY WHILE THIS ISSUE PERSIST. *JB

WHEN THE TRANSMISSION SHIFTS FROM 2ND TO 3RD THERE IS A HARD CLUNKING, ALSO WHEN IT DOWN SHIFTS FROM 3RD TO 2ND. I HAVE HAD THIS 2006 GMC FOR ONLY 10 MONTHS AND I PURCHASED IT NEW. I TOOK IT TO MY LOCAL DEALER FOR THE PROBLEM AND THEY TOLD ME THAT THIS IS NORMAL NOISE FOR A FOUR WHEEL DRIVE. I HAVE HAD MANY 4X4 GMS IN THE PAST AND NOT ONE OF THEM HAS HAD THIS KIND OF A SHIFTING PROBLEM. I HAVE PURCHASED THREE NEW GM'S IN THE LAST 4 YEARS AND I HAVE HAD PROBLEMS WITH ALL OF THEM, I THINK I'M GOING TO TRADE IT IN FOR A TOYOTA. *JB

DT*: THE CONTACT STATED THE VEHICLE'S HYDROBOOST WAS TOO SMALL FOR THE TRUCK AND MADE TOO MUCH NOISE WHEN THE BRAKES OR STEERING WERE USED. THE DEALER DETERMINED THE VEHICLE HAS NO PROBLEMS, BUT THE CONTACT EXPRESSED THERE WILL BE DIFFICULTY DOING TOWING WORK PARTICULARLY GOING UPHILL AND DOWNHILL. THE VEHICLE IS ONLY TWO MONTHS OLD AND HAS BEEN DEMONSTRATING THIS PROBLEM SINCE THE BEGINNING OF THE SECOND MONTH.

DT*: THE CONTACT STATED THREE OF THE FOUR ORIGINAL TIRES HAVE GONE FLAT BECAUSE THE VALVE STEMS LEAK AIR. THE VEHICLE WAS TAKEN TO THE DEALERSHIP AND THE VALVE STEMS WERE REPLACED. *AK

BRAKES FADE NEAR THE END OF A BRAKING CYCLE. NO WARNING LIGHTS DISPLAYED EVEN THOUGH BRAKE PEDAL FELT LIKE IT HAD INCREASED TRAVEL OR MUSHINESS. CAUSE; EXCESSIVE AND PREMATURE CORROSION AND PITTING OF ALL FOUR ORIGINAL EQUIPMENT BRAKE ROTORS. ALSO, EXCESSIVE CORROSION OF BRAKE SENSORS AND BRAKE CALIPERS NECESSITATES AN EXTENSIVE REPAIR. ORIGINAL BRAKE PADS ARE IN GOOD CONDITION REPAIRS NEEDED; REPLACEMENT OF ROTORS, SENSOR, CALIPERS AND BRAKE PADS. BOLTS SEIZED BY CORROSION BROKE ON REMOVAL OF BRAKE COMPONENTS AND THIS RESULTED IN REPLACEMENT OF SENSOR AND ALL CALIPERS. THE COST OF THE REPAIR WAS $2100.00. MY OPINION; POOR QUALITY METALS IN ORIGINAL FACTORY ROTORS CAUSED A SIGNIFICANT BRAKE FAILURE ON THIS VEHICLE WHICH CAUSED BRAKING SAFETY ISSUES AND AN EXPENSIVE REPAIR. THIS IS A SAFETY ISSUE BECAUSE; POOR BRAKING OCCURS AND THE HIGH COST OF REPAIR WILL MEAN SOME OWNERS OF THIS VEHICLE WILL PUT OFF REPAIRS AND CONTINUE OPERATING THIS VEHICLE WITH DAMAGED BRAKE SYSTEMS. I THINK THIS VEHICLE SHOULD BE RECALLED BECAUSE THIS IS A SAFETY ISSUE AND THE MANUFACTURER SHOULD TAKE AT LEAST SOME RESPONSIBILITY TO REPAIR THIS MODEL. THE 2500 (3/4 TON) SERIES THAT I OWN IS MOSTLY USED BY CONTRACTORS AND OTHERS WHO PULL OR HAUL HEAVY LOADS. SO, THE BRAKES REALLY DO NEED TO WORK. *TR

DT*: THE CONTACT STATED WHILE TRAVELING 50 MPH, A BUMPING NOISE WAS HEARD COMING FROM THE REAR OF THE VEHICLE. WHEN THE CONTACT LOOKED IN THE REARVIEW MIRROR, NOTHING WAS NOTICED. WHEN THE VEHICLE WAS PARKED, THE CONTACT FOUND THE DRIVER SIDE TAILLIGHT ASSEMBLY WAS HANGING BY THE WIRES. THE DEALERSHIP DETERMINED THE TABS HOLDING THE TAILLIGHT FRACTURED AND ORDERED A NEW TAILLIGHT ASSEMBLY.

DT*: THE CONTACT STATED THE SPEEDOMETER DISPLAYED AN INCORRECT READING UP TO 10 MPH MORE THAN THE DRIVEN SPEED. THE VEHICLE WAS SEEN BY A DEALER, WHO DETERMINED THIS WAS DUE TO THE OVERSIZED TIRES ON THE VEHICLE WHICH AFFECTED THE OVERALL TELEMETRY. THE VEHICLE WAS SENT TO AN INDEPENDENT REPAIR SHOP AND AN AFTER MARKET HYPER-TECH COMPUTER CHIP WAS INSTALLED TO OVERRIDE THE COMPUTERIZED TELEMETRY OF THE VEHICLE. UPDATED 05/30/06. *AK

SEATS POPPING NOISE WHEN WEIGHT SHIFTS (START,STOP,ETC.)FIRST ATTEMPT WAS TO REPLACE THE SEAT BACK. SECOND WAS TO REPLACE THE ENTIRE SEAT MINUS THE COVER. THIRD TIME IN THE SERVICE MANAGER WANTED TO CONTACT THE AREA GM MANAGER FOR DIRECTION. THE GM AREA MANAGER TOLD THE SERVICE MANAGER TO MAKE NO REPAIR AND DIRECT ME TO CALL GM. THIS TRUCK ALSO HAS BEEN IN FOR SERVICE TO THE BRAKE ROTORS TO BE RE SURFACED WITH ONLY 4,600 MILES ON THE TRUCK. THE TRANSMISSION HAS RE CALIBRATED TWO TIMES ONE FOR THE LOCK-UP TORQUE CONVERTER,AND ONCE FOR A HARD SHIFT FROM FIRST TO SECOND GEAR. THE TRUCK HAS A HARDER SHIFT NOW THAN BEFORE. *JB
