2010 GMC SIERRA 1500 Complaints

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 PRESENT AN ISSUE OF SAFETY. I AM NOT SURE IF IT IS JUST THIS PARTICULAR MODEL. I SUSPECT SO, SINCE IT IS THE BASE MODEL TRUCK. WE HAVE A 2011 GMC TERRAIN, WHICH DOES NOT PRESENT THIS ISSUE. I HAVE CONTACTED THE DEALER ABOUT THIS ISSUE NOW FOR 3 YEARS WITH NO RESOLUTION. THEY ACT AS THOUGH YOU ARE AN IDIOT. *TR

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 OUTWEIGHS THE HEALTH CARE AND HUMAN COSTS THAT ARE BEING BORNE BY OUR CONSUMERS EVERY TIME SOMEONE IS INJURED DUE TO A MANUFACTURER'S FAULTY OR NEGLIGENT HEAD REST DESIGN. UNTIL THE NHTSA MANDATES SUCH PROTECTIONS, AUTO MANUFACTURERS WILL HAVE FREE REIGN TO CONTINUE TO SKIMP ON CONSUMER SAFETY, AND THE U.S. PUBLIC WILL CONTINUE TO SUFFER THE CONSEQUENCES. *TR
