    ON 10/29/2014 I FILED A COMPLAINT WITH ODI NUMBER 10650997 ABOUT THE OUTSIDE DOOR HANDLES ON MY 2010 GMC SIERRA SINCE THREE OF THEM HAD BROKEN OFF SINCE DECEMBER 2013. THEN ON 11/6/2014, THE PASSENGER BACK DOOR HANDLE CAME LOOSE & IS PULLING OUT OF THE DOOR. THIS IS THE ONLY ONE OF THE DOOR HANDLES THAT HAS NOT BEEN PREVIOUSLY REPLACED. ALL OF THE DOOR HANDLE FAILURES HAVE OCCURRED SINCE DECEMBER 2013. THIS PRESENTS A POTENTIAL HAZARD. IT HAS BEEN MY EXPERIENCE ON THE DOOR WITH BROKEN HANDLES THAT IF THE DOOR HANDLE COMES COMPLETE OFF, IT IS HARD TO GET THE DOOR TO LATCH PROPERLY CAUSING IT TO POP OPEN WHICH COULD EASILY HAPPEN WHILE THE VEHICLE IS IN MOTION PUTTING ANYONE SITTING BY THE DOOR IN HARM'S WAY. IT IS VERY DISCONCERTING TO ME THAT ALL FOUR DOOR HANDLES HAVE NOW FAILED. I WOULD DEFINITELY THINK THIS IS A SERIOUS DESIGN FLAW WITH THESE VEHICLES. TWO OF THE HANDLES WERE REPLACED UNDER WARRANTY HOWEVER, THE COST TO REPLACE THE REMAINING TWO IS $200+ EACH. TO DATE GMC IS NOT WILLING TO ADDRESS THE ISSUE. *TR

NOT SURE IF RELATED BUT THE DEALERSHIP HAS REPLACED MY RIGHT REAR SPEAKER SEVERAL TIMES CLAIMING THAT THE SPEAKER IS SEEING SHORTS AND/OR HIGHER POWER OR SHORTING INTERNALLY. BEING THIS IS MULTIPLE TIMES (3 OR 4 TIMES FOR THIS SAME REPAIR) WHAT OTHER ELECTRICAL SYSTEM PROBLEMS WILL I BE SEEING AND WILL ANY OF THESE LEAD TO FIRES OF ADDITIONAL SYSTEM DAMAGE. EVEN WITH THESE KNOW ISSUES AND SERVICE BULLETINS ISSUED ON THE BLOWER SYSTEM AS DOCUMENTED ON THE REPAIR INVOICE, WHILE KNOWING THAT LOSS OF VISION THROUGH THE WINDOW IS POSSIBLE, GM HAS NOT INITIATE ANY CAMPAIGN TO PROACTIVELY FIX THIS. ONLY AFTER THE PROBLEM OCCURS AND IF THE PERSON IS LUCKY TO AVOID ACCIDENTS WILL THEY ADDRESS THIS WHEN YOU COME INTO COMPLAIN ABOUT, BUT BY THAT TIME THEY HOPE IT IS OUT OF WARRANTY SO THEY CAN CHARGE YOU. AFTER ALL IT IS UNSAFE TO DRIVE THE VEHICLE WITHOUT THIS SYSTEM WORKING PROPERLY SO PEOPLE WILL PAY TO GET THIS FIXED. *TR

AS IT TRAVERSED FROM APPROX 42 DEGREES F TO 36 DEGREES F ALL WINDOWS FOGGED SEVERELY SO AS TO RENDER NO VISIBILITY. THE DEFROSTER WAS ENGAGED DURING THIS EVENT. THIS VEHICLE HAS A MANUAL HVAC SYSTEM. THIS HAS OCCURRED NUMEROUS TIMES AS THE TEMPERATURE TRAVERSES BELOW 36 DEGREES F, ALL TIMES RESULT IN EXCESSIVE CABIN MOISTURE AND WINDOW FOGGING.

    ENGINE STOPPED RUNNING, DASH GAUGES BLANK. I MANAGED TO PULL OVER WITHOUT POWER BRAKES OR STEERING! AFTER A FEW MINUTES I WAS ABLE TO RESTART WITH "REDUCED ENGINE POWER, TRACTION CONTROL OFF, AND STABILITRAC" PROBLEMS DISPLAYED ON DASH. I WAS A MILE FROM HOME IN -10F TEMPS! I PULLED IT INTO MY SHOP. DTC CODE P2135 WHICH HAS TO DO WITH THROTTLE POSITION SENSOR. THE DEALER HAS A 2 WEEK DELAY IN GETTING INTO THEIR GARAGE! I FOUND OUT THAT THE THROTTLE BODY/SENSOR IS NOT COVERED UNDER WARRANTY. SO WITH THE COST OF A TOW (CAN'T TRUST THE TRUCK TO MAKE TO DEALER) PLUS THE PART COST, I WILL REPAIR IT MYSELF. THE REASON FOR THIS LETTER, I DISCOVERED THAT THIS HAS HAPPENED TO OTHER GMC TRUCK OWNERS. THEIR VEHICLE QUIT IN THE SAME MANNER. I THINK THAT "REDUCED POWER" IS NOT THE SAME AS NO POWER!!! I WONDER WHAT WOULD HAVE HAPPENED TO ME IF I WAS ON THE FREEWAY DURING RUSH HOURS??? BE PREPARED FOR SOME CREATIVE DRIVING! *TR

    I WAS TRAVELING HOME FROM VACATION AND ABOUT 70 MILES AN HOUR IN MY 2010 GMC SIERRA AND ALL OF A SUDDEN MY TRUCK REVVED UP AND MY TRANSMISSION WENT OUT. I ABOUT GOT HIT FROM BEHIND. I PULLED OVER AND THERE WAS SMOKE COMING FROM THE HOOD. I OPEN THE HOOD AND THERE'S TRANSMISSION FLUID FROM THE FRONT TO THE BACK UNDER THE TRUCK. ONE OF THE COOLING LINES RUBBED THE OTHER AND CHAFFED A HOLE. COST ME 150 DOLLARS IN TOWING FEES. GM DOESN'T WANT TO HONOR THEIR WARRANTY BECAUSE THEY REMOVED THIS PART OFF THEIR WARRANTY IN 2009. TRYING TO COVER UP THEIR MISTAKE .I CALLED GM PRIORITY CARE AND THEY HAD THE TRUCK TOWED TO BECK AND MASTEN GM. THEY ARE TRYING TO CHARGE ME FOR THE REPAIRS WHEN ITS A DEFECT ON GM'S PART. MY QUESTION IS HOW MANY INNOCENT DRIVERS ARE GOING TO GO BANKRUPT PAYING FOR A NEW TRANSMISSION WHEN IT WAS GM'S MISTAKE IN DESIGN. OR EVEN WORSE HOW MANY WILL GET KILLED ON THE HIGHWAY. I THINK I'VE MADE MY POINT! *JS

    MY 2010 GMC SIERRA HAS AN ISSUE WITH THE DEFROSTER NOT DOING AN ADEQUATE JOB WHEN THE TEMPERATURE GOES BELOW 40 DEGREES. THE COMPUTER SYSTEM WILL NOT ALLOW YOU TO TURN ON THE A/C TO DEFROST THE WINDOWS NOR WILL IT ALLOW YOU TO TURN OFF THE RECIRCULATING AIR. SO BASICALLY AFTER 40 DEGREES OUTSIDE YOU ARE JUST PUMPING THE SAME HUMID AIR THROUGH THE CABIN CAUSING SEVERE FOGGING OF ALL THE WINDOWS. I HAVE READ MANY COMPLAINTS ABOUT THIS ONLINE AND THERE IS A TSB IN PLACE TO FIX THE PROBLEM, HOWEVER, SINCE THIS IS A WIDESPREAD ISSUE, WHICH AFFECTS THOSE OF US IN COLDER CLIMATES, I FEEL THAT THERE SHOULD BE A RECALL DONE. THIS COULD BE VERY DANGEROUS. IF YOU HAVE MORE THAN 1 PERSON IN THE TRUCK AT A TIME, THE WINDOWS ARE SO FOGGY YOU NEED TO DRIVE WITH HER HEAD OUT THE DRIVERS SIDE WINDOW JUST TO SEE. I HAVE OWNED THIS TRUCK FOR 2 YEARS NOW AND THIS IS THE COLDEST WINTER WE HAVE HAD IN A WHILE. I DON'T THINK IT GOT BELOW 45 LAST YEAR SO I DIDN'T NOTICE AN ONGOING PROBLEM. NOW IT IS EVERYDAY.

    DRIVING AT APPROXIMATELY 42 MPH THE VEHICLES WARNINGS LIGHTS CAME ON INFORMING ME THAT THE STABILITRAC NEEDED SERVICE, TRACTION CONTROL WAS NO LONGER WORKING AND THE ENGINE WAS OPERATING AT A LOSS OF POWER. THE ENGINE STARTED SHAKING AND THE DIFFERENTIAL STARTED TO CLUNK AS IF IT WERE GOING IN AND OUT OF ENGAGEMENT. AN IMMEDIATE POWER LOSS, I WAS UNABLE TO KEEP UP WITH TRAFFIC AND WAS IN BECOMING A HAZARD TO OTHER MOTORISTS. THE ENGINE STARTED TO PING AND FELT AS IF IT WERE FIRING ON 2 OR 3 CYLINDERS. I PULLED OVER INTO THE BREAKDOWN LANE AND SHUT THE TRUCK OFF. SEVERAL MINUTES LATER I STARTED THE TRUCK AND IT RAN NORMAL, HOWEVER APPROXIMATELY 2 MILES DOWN THE ROAD IT DID THE EXACT SAME THING. I MANAGED TO TAKE THE "BACK ROADS" HOME WITHOUT ENDANGERING ANYONE. THE NEXT MORNING IT STARTED AND RAN NORMAL. YESTERDAY IT HAPPENED AGAIN ONLY THIS TIME I WAS AT A MAJOR INTERSECTION AND ALMOST CAUSED A COLLISION BECAUSE I WAS UNABLE TO GET THROUGH THE INTERSECTION BEFORE THE LIGHT CHANGED. I MADE IT THROUGH AND CALLED TO HAVE THE TRUCK TOWED TO THE DEALERSHIP. VERY DANGEROUS SITUATION. *TR

Safety ratings

NHTSA 5-Star Safety Ratings from government crash tests. Ratings can differ by cab style and 2WD/4WD.

NHTSA hasn't published star ratings for this truck. Many heavy-duty pickups aren't included in NHTSA's crash-test program, so this doesn't mean the truck is unsafe.
