2010 GMC Sierra 1500 complaints

WE WERE DRIVING ON A 2 LANE HIGHWAY GOING 60MPH WHEN ALL OF A SUDDEN THE TRUCK WENT TO 20MPH. THE VEHICLE BEHIND ME ALMOST REAR ENDED ME. I PULLED OVER TO THE SHOULDER AND SAW THE CHECK ENGINE LIGHT WAS ON, AND ALSO THERE WERE OTHER MESSAGES SAYING THAT TRACTION CONTROL WAS OUT, VEHICLE STABILITY WAS OUT, ETC. I WAS A COUPLE OF MILES AWAY FROM THE DEALERSHIP SO I CALLED THEM. LUCKILY THEY WERE OPEN ON SATURDAY. I TOOK IT THERE AND HAD THE THROTTLE BODY REPLACED. THE TRUCK HAS ONLY 18,500 MILES ON IT. THE SERVICE MAN SAID THERE WERE NO RECALLS OR SERVICE BULLETINS FOR THIS PROBLEM. THE LITTLE RESEARCH I HAVE DONE SHOWS THAT MANY OTHER OWNERS HAVE HAD THIS SAME PROBLEM. *TR

THE FIRST TIME WAS NOV.2014 WHEN THE CHECK ENGINE LIGHT CAME ON SOLID ALONG WITH THE TRACTION CONTROL LIGHT ENGINE POWER WAS REDUCED AND THE ENGINE VIBRATED AND WOULD NOT GO OVER 20 MPH.I LEFT THE TRUCK PARKED FOR 3 DAYS AND WHEN CRANKED THE TRUCK ALL LIGHTS WERE OFF AND THE TRUCK RAN FINE.ONCE IN DEC. 2014 AND ONCE IN JAN.2015 THE SOLID CHECK ENGINE LIGHT CAME ON BUT THE TRUCK RAN FINE AND AFTER A FEW DAYS WENT OFF. THE FIRST WEEK OF FEB. 2015 THE CHECK ENGINE AND TRACTION CONTROL LIGHT CAME ON ENGINE POWER WAS REDUCED AND ENGINE VIBRATION. I WAS ABLE TO DRIVE SLOWLY ONLY TO AN INDEPENDENT MECHANIC THAT I NORMALLY GO TO BECAUSE HE WAS CLOSER THAN THE DEALERSHIP AND I WANTED IT CHECK IMMEDIATELY SINCE THE WARNING LIGHTS WERE ON.HIS CODES SHOWED THE THROTTLE BODY WITH SENSOR NEEDED TO BE REPLACED.HE STATED HE LEFT THE CODES IN EVEN THOUGH THE WARNING LIGHTS WENT OFF BECAUSE HE THOUGHT THIS WORK WAS COVERED UNDER WARRANTY.I IMMEDIATELY CALLED THE DEALERSHIP AND THEY WANTED TO MAKE AN APPOINTMENT FOR THE FOLLOWING WEEK AND WHEN I TOLD THEM ALL THE WARNING LIGHTS HAD WENT OFF THEY STATED IT WOULD PROBABLY BE A WASTE OF TIME TO CHECK ON THEIR COMPUTER. I TOLD THE DEALERSHIP SERVICE DEPT. ABOUT HOW YOU DON'T KNOW WHEN THIS WILL HAPPEN AND WHEN IT DOES YOU ARE BASICALLY STRANDED BECAUSE THE VEHICLE WILL BARELY MOVE. THE NEXT WEEK FEB.11, 2015 IT HAPPENED AGAIN AND ALL 3 TIMES I WAS LUCKY I WAS NOT IN ALOT OF TRAFFIC OR TRAVELING AT HIGH SPEEDS OR ON A STEEP GRADE.IF I WOULD HAVE BEE

SATURDAY, JULY 27, 2013, OUR 2010 GMC SIERRA K1500 CAUGHT FIRE AND WAS COMPLETELY DESTROYED AS MY HUSBAND WAS DRIVING ON THE INTERSTATE. AS SMOKE BEGAN TO FILL THE CAB AND THE "CHECK ENGINE" LIGHT CAME ON, HE ATTEMPTED TO BRAKE SO THAT HE COULD ESCAPE, BUT THE BRAKES WERE GONE, AND THE BRAKE PEDAL WENT ALL THE WAY TO THE FLOOR. IMAGINE HIS TERROR AS HE REALIZED THAT AT AGE 65, HE MAY HAVE TO JUMP OUT OF THE TRUCK OR BE CONSUMED BY A FIRE. HE WAS ABLE TO DOWN-SHIFT TO SLOW THE TRUCK ENOUGH TO USE THE EMERGENCY BRAKE TO GET THE TRUCK STOPPED JUST IN TIME TO ESCAPE FROM THE TRUCK AND GET FAR ENOUGH AWAY TO AVOID BODILY INJURY AS THE TRUCK AND OUR BELONGINGS BURNED COMPLETELY. WE ARE GRAVELY CONCERNED THAT THE TRUCK, WHICH WAS PURCHASED THREE YEARS AGO THIS MONTH, AND HAD ONLY 18,000 MILES ON IT, CLEARLY WAS A RISK TO OUR LIVES AND THE LIVES OF OTHERS. WE HAVE THREE ADULT CHILDREN AND SEVEN GRANDCHILDREN & OFTEN HAD ONE OR MORE OF THEM WITH US AS WE TRAVELED IN THIS VEHICLE. HAD WE NEEDED TO UNBUCKLE THE BABIES FROM THEIR CAR SEATS AND/OR ASSIST THE TODDLERS IN GETTING OUT, THE OUTCOME MAY HAVE BEEN VERY DIFFERENT, AND IT HAUNTS US TO KNOW THAT THIS COULD HAVE BEEN THE CASE. ALL HAD RIDDEN IN THIS TRUCK IN THE WEEKS PRECEDING YESTERDAY'S FIRE. AS MY HUSBAND HEADED HOME TO MONTANA AT THE COMPLETION OF HIS TRAVEL TO VISIT OUR CHILDREN AND GRANDCHILDREN, HE ASCENDED, THEN DESCENDED "LOOKOUT PASS" ON I-90 AT THE MONTANA/IDAHO BORDER - A PASS THAT IS STEEP AND VERY BUSY WITH SUMMER VA

INSIDE DRIVER DOOR HANDLE CHROME IS FLAKING. 3/9/13 IT CUT MY INDEX FINGER FAIRLY DEEP AND APPROXIMATELY 1/2 INCH IN LENGTH. OF COURSE IT BLED ALL OVER MY SUIT AS I WAS HEADING TO BE THE BEST MAN AT A WEDDING. 7/21/13. MY SON WAS GETTING OUT OF THE DRIVERS DOOR AND RECEIVED THE SAME INJURY. *TR

THE WINDSHIELD AND THE SIDE WINDOWS OF MY NEW 2010 GMC SIERRA 1500 WT, HAVE AN EXTREME TENDENCY TO FOG OVER IN TEMPERATURES NEAR THE FREEZING POINT. I HAVE READ, AND OBSERVED, THAT THE AC COMPRESSOR BECOMES AUTOMATICALLY DISABLED WHEN THE OUTSIDE TEMPERATURE GETS NEAR THE FREEZE ZONE (I THINK THE ACTUAL THRESHOLD IS SOMEWHERE AROUND 40 DEGREES F). WITH THE AC DISABLED, THE DEFROST MODE CANNOT KEEP THE WINDOWS CLEAR. THE PROBLEM IS MAGNIFIED WHEN THERE ARE TWO OR THREE INDIVIDUALS IN THE CAB. AT THAT POINT, IT IS EXCEEDINGLY DIFFICULT TO CLEAR THE SIDE WINDOWS, EVEN TO THE POINT THAT FROST FORMS ON THE INSIDE WINDOW SURFACE! VERY RECENTLY, WHILE TRAVELING TO WORK DURING MY 40 MILE COMMUTE, I WAS RUNNING THE AC, WITH THE TEMP CONTROL SET TO A COMFORTABLE LEVEL AND THE BLOWER ABOUT THE MEDIUM SETTING AND FLOWING THROUGH THE MAIN VENTS. THE OUTSIDE TEMPERATURE WAS, APPARENTLY, HOVERING NEAR THE POINT WHERE THE ELECTRONICS DISABLE THE COMPRESSOR. THE WINDSHIELD AND BOTH SIDE WINDOWS FOGGED OVER SUDDENLY. I NOTICED THE AC LIGHT WAS OUT, SO I SWITCHED TO DEFROST MODE AND HI BLOWER. THE WINDSHIELD DID CLEAR IN ABOUT A MINUTE OR TWO, BUT ALL OF THAT HAPPENED WHILE DRIVING DOWN THE TURNPIKE AT 70 MPH. THIS SEEMS TO BE A SIGNIFICANT SAFETY CONCERN....AT LEAST FOR ME AND MY FAMILY. IF THE AC COMPRESSOR HAD STAYED ENABLED, THIS WOULD NEVER HAVE HAPPENED. IT IS VERY DIFFICULT TO STOP CONDENSATION BUILDUP IF YOU CANNOT RUN THE AC TO DRY THE CABIN AIR. THIS DESIGN CONFIGURATION SEEMS TO PRES

UPON START UP, AFTER SITTING FOR SEVERAL HOURS OR OVERNIGHT, THE CAR FAILS TO STOP PROPERLY FOR THE FIRST MINUTE. THIS IS DANGEROUS AS THE PEDAL IS SOFT AND INCONSISTENT AND STOPPING TIMES AND DISTANCES ARE SUBSTANTIALLY GREATER THAN NORMAL OR ACCEPTABLE TOLERANCES. IT IS DANGEROUS TO BOTH PEOPLE AND PROPERTY AS THE CAR DOES NOT STOP AS IT SHOULD. I HAVE EXPERIENCED TAPPING INTO GARAGE DOORS DUE TO THE FAILURE OF THE CAR TO STOP PROPERLY. IN THE EVENT THAT A PERSON WOULD HAVE BEEN PRESENT, IT COULD HAVE BEEN DEADLY. I HAVE ALSO EXPERIENCED NUMEROUS CLOSE CALLS WHEN MANEUVERING IN GARAGES. A FRIEND HAS THE SAME TRUCK AND HAS ASKED IF I EXPERIENCED THE PROBLEM WITH STOPPING THE TRUCK AFTER START UP. I TOOK THE CAR TO GO GMC IN GOLDEN COLORADO ON MULTIPLE OCCASSIONS. THEY DOWNPLAY THE EVENT AND STATE THAT THEY CANNOT GET THE TRUCK TO DUPLICATE THE PROBLEM WHEN TESTING. AFTER MULTIPLE TRIPS TO THE DEALER, THEY ARE NOW SAYING THAT IT TAKES A MINUTE OR TWO FOR THE VACUM BOOSTER, OR SOMETHING LIKE THAT, TO PRESSURIZE AND THE BRAKES ARE WORKING "NORMALLY." IF THIS IS NORMAL, IT DOES NOT CONFORM WITH STANDARD DRIVING BEHAVIOR. HAVING TO WAIT FOR YOUR BRAKES TO PRESSURIZE FOR A MINUTE OF SO IS NOT NORMAL. THANKS.

2004 GMC SIERRA WITH 5.3L ENGINE. AT 53,920 MILES BEGAN TICKING AT COLD START UP. CONFIRMED BY GMC DEALER TODAY THAT CYLINDER HEAD HAS CRACK WHICH CAUSED COOLANT TO SEEP INTO ENGINE OIL. $3,800 TO REPLACE DEFECTIVE CYLINDER HEADS AND INSTALL NEW LIFTERS. TECHNICAL SERVICE BULLETIN # 06-06-01-019B. THE CYLINDER HEADS IN THIS ENGINE ARE MANUFACTURED BY "CASTECH". *TR

I RECENTLY PURCHASED A 2010 GMC SIERRA CREW CAB. THE REAR SEAT HEAD RESTRAINTS ARE INADEQUATELY AND/OR DEFECTIVELY DESIGNED, AND WILL OFFER LITTLE PROTECTION TO THE REAR SEAT PASSENGERS IN THE EVENT OF A REAR END COLLISION. THE RESTRAINTS ARE MOUNTED ON SHORT POSTS, WHICH DO NOT EXTEND HIGH ENOUGH TO OFFER PROTECTION TO MOST INDIVIDUALS WHO ARE SEATED IN THE REAR. THE POSTS ALSO DO NOT LOCK IN PLACE, (LIKE THE FRONT HEADRESTS) AND SIMPLY SLIDE UP AND DOWN FREELY. I CONTACTED GMC BY LETTER, AND REQUESTED THAT THEY MODIFY OR REPLACE THE HEADRESTS, BUT THEY REFUSED, STATING THAT THE VEHICLE WAS DESIGNED TO PASS ALL FEDERAL SAFETY STANDARDS. AFTER DOING SOME RESEARCH, I REALIZED THAT AUTO MANUFACTURERS ARE NOT REQUIRED TO INSTALL HEAD RESTRAINTS ON THE REAR SEATS OF PASSENGER VEHICLES, AND THAT THE SHAPE, SIZE AND LOCATION OF THE RESTRAINTS CONTINUES TO VARY FROM VEHICLE TO VEHICLE. IT THEREFORE APPEARS THAT MANY VEHICLES, SUCH AS MINE, OFFER INADEQUATE HEAD PROTECTION FOR ALL BUT THE FRONT SEAT PASSENGERS. INDEED, THE PROTECTION IS SO POOR IN THE SIERRA, THAT ANY FRONT OR REAR COLLISION WILL LIKELY RESULT IN THE REAR SEAT PASSENGERS' HEADS COLLIDING WITH THE REAR WINDOW, CAUSING HEAD TRAUMA IN ADDITION TO THE CERVICAL TRAUMA SUSTAINED FROM THE LACK OF HEAD AND NECK SUPPORT. I AM QUITE DISAPPOINTED THAT MY VEHICLE OFFERS SUCH INADEQUATE PROTECTION, AND HOPE THAT THE NHTSA WILL TAKE ACTION ON THE ISSUE. THE COST OF INSTALLING ADEQUATE HEAD RESTRAINTS IN ALL U.S. VEHICLES SURELY OU
