ELECTRONIC STABILITY CONTROL (ESC)
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

VISIBILITY/WIPER
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.

ENGINE, FUEL/PROPULSION SYSTEM, SEAT BELTS
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 VACATION TRAVEL AS WELL AS CONSISTENT HEAVY SEMI-TRUCK TRAVEL. THE CURVES ON LOOKOUT ARE TREACHEROUS: THE RATE OF ACCIDENTS AND SEMI-TRUCK ROLLOVERS ON THE CURVES IS HIGH WITHOUT AN EXTRAORDINARY EVENT SUCH AS A BURNING VEHICLE. IF OUR TRUCK HAD CAUGHT FIRE EVEN THREE OR FOUR MILES EARLIER AS HE WAS DESCENDING THE PASS, THE OUTCOME IS ALMOST UNTHINKABLE. *TR

DEALER PUT ME ON A GM WIDE BLACKLIST AND SO FRUSTRATING. HAVE REPORTED TO POLICE, BUT JUST WANT TO GO TO ANOTHER GMC DEALER TO HAVE FIXED. GM CUSTOMER SERVICE HAS NOT HELPED AND KEEPS CALLING THE FIRST DEALER TO REQUEST THEIR PERMISSION AND IT HAS BEEN DENIED. DEALER THAT COMMITTED ID THEFT: FERGUSON GMC BROKEN ARROW, OK 74011 I REALLY LIKE THE PICKUP, BUT UNFAIR TO HOLD UP WARRANTY/SAFETY REPAIRS BECAUSE OF THE ID THEFT.

VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM, ENGINE AND ENGINE COOLING
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

ENGINE AND ENGINE COOLING
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

SERVICE BRAKES, HYDRAULIC
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.

ENGINE AND ENGINE COOLING
TL* THE CONTACT OWNS A 2010 GMC SIERRA 1500. THE CONTACT STATED THAT WHEN THE PISTONS WERE LOOSE AND STRUCK THE CYLINDER WALL, IT WOULD LOOSEN UP THE ENGINE AND CAUSED AN ABNORMAL KNOCKING FROM THE ENGINE. THE DEALER WAS NOTIFIED OF THE FAILURE WHO ADVISED THE CONTACT THAT THE FAILURE WAS NOTHING TO BE CONCERNED ABOUT AND WAS NOT HURTING THE ENGINE. THE MANUFACTURER WAS NOTIFIED WHO STATED TO THE CONTACT THAT THEY WOULD SPEAK WITH THE DEALER TO DETERMINE THE REMEDY FOR THE FAILURE. THERE WERE NO RECALLS FOR THE FAILURE. THE FAILURE MILEAGE WAS 5,000 AND THE CURRENT MILEAGE WAS 24,000. UPDATED 01/10/12*LJ

VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM, VISIBILITY
DURING A TRIP ALONG WA HIGHWAY 2, WESTBOUND THRU STEVENS PASS, THE TEMPERATURE WAS DROPPING AS INDICATED BY THE VEHICLES OUTSIDE TEMPERATURE INDICATION. 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. THIS EVENT HAS BEEN REPORTED BY OTHER 2010/2011 GMC/SILVERADO/AVALANCE, ETC OWNERS. GMC IS AWARE BUT HAS NO FIX AND DEALERS OFFER NO FIX. *KB

INTERIOR LIGHTING
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.
