NOTICED MUSHY, VIBRATING BRAKES. TOOK IT TO TIRE STORE AND WAS ADVISED THE BRAKE BOOSTER AND VACUUM PUMP ARE BAD. I'VE HAD SEVERAL CLOSE CALLS IN PARKING LOTS, AS THE VEHICLE IS SLOW TO RESOND TO THE APPLICATION OF THE BRAKES. THE DRIVERS SEAT IS ALSO LOOSE. IT MOVES FROM SIDE TO SIDE AS I GO AROUND CORNERS. I'M AFRAID IT WILL COME OFF THE RAILS OR WORSE YET, NOT SECURE ME IN THE EVENT OF AN ACCIDENT.

SEAT BACK PIVOT PIN BROKE. THE SEAT CAN ONLY RECLINE. THIS IS VERY SIMILAR TO RECALL 95V246000. BUT MY VIN DOESN'T SHOW UP WHEN SEARCHED. WHY IS MY VIN NOT INCLUDED? THIS IS A 1994 GMC SIERRA SLE. THANKS

I HAVE HAD MY TRUCK BACK THE DEALERSHIP 8 TIMES FOR THE SAME PROBLEM A VIBRATION THAT YOU CAN FEEL IN THE SEAT STEERING WHEEL AND GAS PEDAL, THEY HAVE HAD THE FACTORY ENGINEERS OUT THREE TIME AND LOOKED AND WORKED ON IT, FIRST TIME THE ENGINEER DID A COUPLE OF THINGS AND SAID THAT IT WAS UP TO FACTORY SPECS AND THAT WAS ALL HE COULD DO, I DROVE IT HOME AND BEFORE I WAS A BLOCK AWAY I COULD TELL THAT THEY DID NOT FIX IT, WHEN I GOT HOME I CALLED THE DEALER BACK AND TOLD HIM SO HE CALLED GM AND THE NEXT WEEK THEY SENT OUT THE SAME GUY AND THIS TIME HE WORKED ON 5 OR 6 OTHER THINGS THAT HE DID NOT WORK ON THE FIRST TIME AFTER TELLING ME THEY DID ALL THEY COULD DO THE FIRST TIME. RIGHT THERE TELLS YOU THEY ARE LYING IF THERE WAS NOTHING THEY COULD DO WHY COME BACK AND WORK ON IT AGAIN! BUT AFTER HE GOT DONE IT WAS JUST LIKE IT WAS, I WILL TRY TO LIST SOME OF THE STUFF THAT THEY SAID THEY DID, 1) ROTATED THE TIRES 2) RE-TORQUE THE WHEELS 3) BALANCED THE TIRES 4) BALANCED THE DRIVE SHAFT 5) SHIMMIED THE REAR END 6) CHECKED THE REAR SHOCKS 7) TOOK OFF DEALER INSTALLED MUD FLAPS! 8) CHECKED THE EXHAUST SYSTEM, I KNOW BUT THEY DID 9) ROAD FORCED TESTED THE TIRES TWICE AND REPLACED TWO THE SECOND TIME AND RE-BALANCED THE TIRES. AND I'M SURE I HAVE NOT LISTED ALL THEY HAVE TRIED, AND STILL I HAVE THE SAME PROBLEM, THIRD TIME THE ENGINEER CAME OUT HE HAD THE REGIONAL MANAGER WITH HIM AND THIS TIME THEY DROVE MY TRUCK AND 2 OTHERS THEY HAD ON THE LOT AND SAID THAT THEY ARE SIMILAR TO MINE AND THEY WAS NOT GOING TO DO ANY MORE TO MY TRUCK THAT THEY HAD DONE ALL THEY COULD OR WOULD DO BUT IF I HAD ANY OTHER PROBLEMS TO BRING IT BACK.

THE DRIVER'S SIDE SEAT HEATER RANDOMLY COMES ON. IF YOU TURN IT OFF IT COMES RIGHT BACK ON AGAIN AND CYCLES THROUGH THE VARIOUS HEAT SETTINGS. IT CREATES A DANGEROUS DISTRACTION IN THE FLORIDA HEAT. I'VE TAKEN IT TO NUMEROUS DEALERS, NONE OF WHICH CAN FIX IT. I CALL GM AND THEY WON'T EVEN CONSIDER IT UNTIL I TAKE IT BACK TO A DEALER SAYING THEY WILL ONLY GET INVOLVED IF I HAVE TAKEN IT TO A DEALER WITHIN THE LAST 30 DAYS. ONE DEALER TOLD ME THAT WAS A LIE, THERE IS NO 30 DAY REQUIREMENT. THIS ISSUE IS MORE OF A DISTRACTION THAN TEXTING. LOOKING IT UP ONLINE IT'S A COMMON PROBLEM BUT GM DENIES IT EVEN THOUGH GM DID ISSUE A TSB TO HAVE THE DRIVERS DOOR MODULE REPROGRAMMED. I HAD THAT DONE AND IT MADE THE PROBLEM WORSE. A STRAIGHT UP SAFETY ISSUE. I HAVE THE SAME PROBLEM WITH A 2005 SUBURBAN AND FILED A COMPLAINT ON THAT ONE TOO. NOTHING CAME OF THAT EITHER SO IT APPEARS THIS SITE AND AGENCY IS NOTHING MORE THAN A SOUNDING BOARD. GM AND NHTSA CANNOT AFFORD TO DISTANCE THEMSELVES FROM THIS.

THE DRIVER SEAT HEATER RANDOMLY TURNS ON BY ITSELF. IT RANDOMLY SWITCHES FROM THE SEAT TO THE BACK OF THE SEAT TO BOTH AT THE SAME TIME, IN NO PARTICULAR ORDER. WHEN I TURN IT OFF IT JUST COMES RIGHT BACK ON AGAIN. I HAD THE MODULE IN THE DOOR REPLACED ONE TIME, BUT IT STILL DOES IT. I LIVE IN THE SOUTH, SO IT'S EXTREMELY UNBEARABLE DURING THE SUMMER MONTHS. I WILL GO FOR WEEKS AT A TIME WHEN IT DOESN'T DO IT, BUT THEN IT JUST SEEMS TO START AGAIN. THERE REALLY DOES NOT SEEM TO BE ANYTHING IN PARTICULAR THAT TRIGGERS IT. I THOUGHT MAYBE IT WAS GETTING WET WHEN IT RAINS, BUT SINCE I LIVE IN THE SOUTH WE HAVE HIGH HUMIDITY 95% OF THE TIME, SO WE HAVE MOISTURE PROBLEMS HERE ALL THE TIME. I CAN GO FOR WEEKS THAT IT DOESN'T HAPPEN, THEN IT JUST STARTS UP AGAIN. I HAVE SEARCHED THE PROBLEM ON GOOGLE AND FOUND THAT OTHER PEOPLE COMPLAIN ABOUT THE SAME PROBLEM WITH THIS PARTICULAR MODEL, BUT I CAN NOT FIND A SAFETY RECALL ISSUED BY GMC.

I HAVE A 2014 GMC SIERRA SLT WITH POWER SEATS. THE DRIVER'S SEAT IS LOOSE (NOT THE SAME ISSUE THAT WAS RECENTLY RECALLED WITH MANUALLY RECLINING SEATS). WHEN YOU MAKE A SHARP TURN AT SPEED THE DRIVERS SEAT SLIDES LEFT OR RIGHT DEPENDING ON THE DIRECTION YOU ARE TURNING. THERE ARE NUMEROUS COMPLAINTS IDENTICAL TO THIS ONE ON THE FORUMS ONLINE AND GM CLAIMS THEY HAVE NO SOLUTION AND TO SPEAK WITH THE LOCAL DEALER. MY LOCAL DEALER DOES NOT NOW KNOW WHAT TO DO AND SAYS THEY CANNOT FIX IT. THIS IS A VERY DANGEROUS SITUATION AND COULD CAUSE AN ACCIDENT! PLEASE HAVE GM FIX IT OR ISSUE A RECALL!

SEATS
THE HEAD RESTS OF OUR NEW TRUCK (PURCHASED DEC 2012) PROJECT SO FAR FORWARD THAT IT FORCES MY HEAD TO TILT DOWNWARD. THERE IS NO FORWARD/BACK ADJUSTMENT TO THE HEAD REST, AND TURNING THE HEAD REST BACKWARDS TO MAKE IT BEARABLE MEANS IT NO LONGER WILL SERVE WELL TO PREVENT NECK INJURIES IN A CRASH. FOR SHORTER DRIVES, THE FORCED HEAD TILT IS UNCOMFORTABLE, BUT FOR LONGER DRIVES IT CAUSES ENOUGH PAIN THAT I HAD TO SEE A CHIROPRACTOR (AND I'M AN ATHLETIC, HEALTHY PERSON!). THE DEALER AND MANUFACTURER CONTEND IT WORKS AS DESIGNED FOR SAFETY IN A CRASH. BUT IF I CAN'T SIT IN IT FOR NORMAL DRIVING WITHOUT EXPERIENCING NECK/BACK PAIN, HOW "SAFE" IS THAT? I NOTICED THE NEW 2014 GMC 1/2-TON PICKUPS HAVE A HEAD REST WITH A NOTICEABLY LESS ANGULAR DESIGN, INDICATING GMC RECOGNIZED THE HEAD REST DESIGN IN MY 2013 3/4-TON TRUCK IS, AT BEST, A POOR ONE AND, AT WORST, A POTENTIALLY DANGEROUS ONE. IS THERE ANY RECOURSE TO GETTING GMC TO REPLACE MY HEAD RESTS WITH THE NEW DESIGN (OR EVEN AN OLDER ONE, LIKE THE STRAIGHT-UP-AND-DOWN ONES I HAVE IN MY 2003 CHEVY TAHOE)?

DRIVER SEAT HEATER TURNS ON BY ITSELF CREATING AN EXTREMELY UNSAFE DRIVING CONDITION IN THE SUMMERTIME IN HIGH DENSITY TRAFFIC WITH SUN GLARE A PROBLEM AND AN INABILITY TO EFFECTIVELY TURN THE SEAT HEATER OFF. THIS PROBLEM HAS BEEN REVIEWED BOTH BY THE LOCAL CHEVROLET AND GMC DEALERS WITH THE ULTIMATE CORRECTIVE ACTION BEING TO DISCONNECT THE SEAT HEATING ELEMENTS. WHILE THIS ADDRESSES SAFETY FOR ME IT FALLS SHORT OF PROVIDING ME WITH A FUNCTIONING SEAT HEATER AS PURCHASED. ALSO THE CORRECTIVE ACTION DOES NOT GIVE CONSIDERATION TO A POTENTIALLY GENERAL EXISTING PROBLEM---WHICH IS THE MORE IMPORTANT REASON THAT I MAKE THIS REPORT.

THE CONTACT WAS ALSO DRIVING WHEN THE FAILURE OCCURRED TWO YEARS AGO. THE DEALER AND MANUFACTURER STATED THAT THEY COULD NOT ASSIST. THE CURRENT MILEAGE WAS 193,377 AND FAILURE MILEAGE WAS APPROXIMATELY 120,000.

2000 GMC SIERRA FRONT PASSENGER SEAT BELT NOT WORKING PROPERLY. CUSTOMER STATES THAT THE SEAT BELT IS HARD TO PULL AND DOES NOT RETRACT PROPERLY. *KB THE CONSUMER INITIALLY REPORTED THE SEAT BELT WAS MAKING A SQUEAKING NOISE. THE DEALER REPLACED THE SEAT BELT, BUT THE NEW SEAT BELT LOCKED UP ON PASSENGERS RESTRICTING THEIR ABILITY TO LEAN FORWARD AND WAS VERY TIGHT. THE DEALER REPLACED THE SEAT BELT TWO MORE TIMES AND THE RESTRICTION PROBLEM WAS STILL PRESENT. THE DEALER STATED THE BELT WAS SUPPOSE TO WORK THAT WAY. THE CONSUMER STATED THE ORIGINAL BELT NEVER WORKED THAT WAY. THE CONSUMER STATED THE LAST SEAT BELT THAT WAS REPLACED NOT ONLY RESTRICTED MOVEMENT, BUT IT DID NOT RETRACT SMOOTHLY. ONCE THE SEAT BELT WAS IN USE, IT DID NOT RECOIL LEAVING THE BELT LOOSE AND USELESS. IN ADDITION, THE ARM REST KEPT FALLING OFF AND THE SEAT NO LONGER RECLINED.

I HAVE A 1999 GMC SIERRA EXTENDED CAD TRUCK THE DRIVERS SEAT ADJUSTMENT MADE OF PLASTIC WHEN IT BREAKS THE SEAT WILL NOT LOCK. THE SEAT BELT IS ATTACHED TO THE SEAT SO IN THE EVENT OF AN ACCIDENT ALL THAT IS HOLDING IS FLIMSY PLASTIC. I CHECKED ALL THE SALVAGE YARDS IN MY AREA THEY SAID EVERY TRUCK THAT THEY HAVE THAT HAS WRECKED THE PLASTIC SLIDE IS BROKEN. TO ME, MY WIFE AND MY LIFE ARE WORTH MORE THAN THIS PLASTIC PIECE. GM NEEDS TO RECALL AND EITHER FIX THIS PIECE WITH METAL OR DIFFERENT SEAT TRACKS. MY SEAT BROKE JUST ADJUSTING IT.

1-SEAT ADJUSTMENT 2-SEAT WILL NOT LOCK IN POSITION-SLIDES FREELY FRONT TO BACK 3-TEMPORARILY LOCKED FAILED PIECE INTO USABLE POSITION-CANNOT ADJUST TO ANY OTHER POSITION DUE TO FAILED PLASTIC BLOCK. RESEARCHED COMPLAINTS FOR 99 GMC SIERRA TRUCK AND FOUND 10 EXISTING IDENTICAL FAILURES. THESE ARE COMPLAINTS-566049, 758819, 855016, 862903, 877718, 10020665, 10022698, 10066125, 10074822. I AM SURE THERE WILL BE ADDITIONAL COMPLAINTS UNDER "MIRROR" VEHICLES SUCH AS CHEVROLET AND CADILAC AND OTHER YEARS. I HAVE IDENTIFIED THE PIECE AS A PLASTIC BLOCK APPROXIMATELY 1 INCH WIDE BY 2.5 INCHES LONG WITH A LEVER, SPRING AND PIN ASSEMBLY. THE "U" PORTION OF THIS BLOCK FAILS CAUSING THE SEAT TO SLIDE FREELY CREATING A SEVERE SAFETY ISSUE. THIS IS CLEARLY AN UNSAFE AND POOR DESIGN. I HAVE PIECES OF BROKEN BLOCK FOR REFERENCE AND WILL CONTINUE TO ESCALATE THIS AS FAR AS NECESSARY FOR RESOLUTION FROM GM.

DT: THE CONTACT OWNED A 2003 GMC SIERRA 1500 HD. CONTACT RECEIVED A RECALL LETTER FOR AUTOMATIC SEAT FAILURE. WHEN GETTING OUT OF THE VEHICLE SEAT WAS SUPPOSE TO MOVE BACK TO LET CONSUMER OUT, BUT INSTEAD IT WAS MOVING FORWARD, CAUSING CONSUMER TO GO UNDER THE STEERING WHEEL. CONSUMER CALLED THE DEALERSHIP FOR THE LAST SIX MONTHS, THEY KNEW THE PROBLEM EXISTED, BUT WERE UNABLE TO FIX THE PROBLEM. THEREFORE, THERE WAS NOTHING THAT THEY COULD DO RIGHT NOW. THE INSTRUMENT PANEL WILL JUST CAME ON WITHOUT ANYONE TOUCHING ANYTHING. THE PROBLEM WITH THE SEAT HAPPENED AT LEAST ONCE A DAY. IT WILL RESET ITSELF ALL THE TIME.
