    A CRACK HAS FORMED ON THE PASSENGER SIDE OF THE DASH BOARD NEAR THE AIR BAG. THIS SHOULD NOT OCCUR IN A VEHICLE OF THIS AGE. THE VEHICLE HAS BEEN TO THE DEALER ON NUMEROUS OCCASIONS WITHOUT ANY MENTION OR ACTION TO REPAIR. I WILL BE CONTACTING THEM ON MONDAY ABOUT COVERING THE REPAIR. I BELIEVE THAT THIS IS A MANUFACTURING DESIGN ISSUE AND THE DASH SHOULD BE REPLACED UNDER WARRANTY. IN THE MONTH OF JUNE 2015, I HAD TO HAVE MY MASTER CYLINDER AND BRAKE BOOSTER REPLACED. THE FIRST OCCURRENCE WAS IN JANUARY 2015 OF THIS YEAR AND I FILLED THE MASTER CYLINDER WITH FLUID BECAUSE OF THE BRAKE WARNING SYSTEM CAME ON AND THE BRAKE FLUID IN THE MASTER CYLINDER WAS AT THE MINIMUM LEVEL. THE DEALERSHIP ADVISED TAT IT COULD BE THE RESULT OF LOW BRAKES AND TO KEEP AN EYE ON IT AND IF IT LOOSE BRAKE FLUID TO BRING IT IN.WHEN IT OCCUR AGAIN IN JUNE 2015, I TOOK IT INTO THE DEALER. IT WAS DETERMINE THAT THE BRAKE MASTER CYLINDER WAS LEAKING INTO THE BRAKE BOOSTER CAUSING THE WARNING LIKES ON THE DASH TO ILLUMINATE. AT JUST OVER 40,000 MILES, THIS SHOULD BE COVER BY GM AS A WARRANTY ITEM. I BELIEVE I AM DUE A REFUND.

    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

    I WAS TRAVELING ON HIGHWAY 151 AT 70 MPH WHEN I RECEIVED A MESSAGE STATING STABILITRAK WAS DISABLED, FOLLOWED BY REDUCED ENGINE POWER MESSAGE. WITHIN SECONDS MY TRUCK WENT FROM 70 MPH TO 35 MPH WHILE ON THE HIGHWAY WITH A SEMI-TRUCK BEHIND ME, A CAR IN THE FAST LANE ON MY LEFT SIDE, AND SNOW ON THE RIGHTSIDE SHOULDER. I QUICKLY TAPPED MY BRAKES AND PUT ON MY RIGHT TURN SIGNAL TO NOTIFY TO THE SEMI-TRUCK DRIVER THAT I WAS QUICKLY TURNING OFF THE HIGHWAY AND DRASTICALLY REDUCING MY SPEED LOWER THAN THE ALLOWED STATE HIGHWAY MINIMUM SPEED LIMIT. CONSIDERING THE HIGHWAY TRAFFIC AND THE SPEED AT WHICH MY TRUCK REDUCED SPEED IN SUCH A QUICK MANNER, IT WAS A MIRACLE I WAS NOT REAR-ENDED BY THE SEMI-TRUCK DRIVER. THIS NOT ONLY HAPPENED TO BE ONCE ON SUNDAY, BUT TWICE ON THE SAME DAY WITHIN ABOUT 20 MILES FROM THE FIRST INCIDENT. *TR

    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

    THE INSTRUMENT CLUSTER LIGHTING PRESENTS A HAZARD AT NIGHT. THE DIMMING SYSTEM DOES NOT SUFFICIENTLY DIM THE CLUSTER. THE GLARE INTERFERES WITH THE DRIVER'S VISION TO THE OUTSIDE OF THE VEHICLE, ESPECIALLY WHILE DRIVING ON RURAL ROADS WHICH LACK AMBIENT LIGHT. THIS HAS BEEN CONFIRMED BY BOTH THE DEALER AND GMC CUSTOMER SERVICE AS BEING THE WAY IT IS DESIGNED.
