  ENGINE WILL INCREASE IDLE FROM 700 TO 900 AT ANY TIME. ONE CAN BE SITTING AT A TRAFFIC LIGHT AND IT MIGHT INCREASE OR DECREASE. I PULL A 5TH WHEEL (35 FEET) AND IT IS VERY DIFFICULT TO STOP WITH THE ENGINE TRYING TO KEEP GOING. ALSO IT IS VERY SCARY TO STOP ON SLIPPERY ROADS. THIS DID NOT START UNTIL THE VEHICLE HAD APPROX. 35,000 MILES ON IT. THE DEALER TELLS ME IT IS NORMAL, BUT I HAVE TALKED TO OWNERS OF THE GM DIESEL FROM MODEL YEAR 2008 THROUGH 2015 AND NONE OF THEM HAVE THIS CONDITION. *TR

  I HAVE GOODYEAR WRANGLER SR-A 265 60R20 TIRES ON MY SIERRA DENALI HD 2500. I WAS ON THE WAY BACK FROM NC VIA I-95 AND PULLED OVER SO MY WIFE COULD NURSE OUR 3 WEEK OLD. ME AND THE BOYS WENT IN K-MART FOR A FEW MINUTES. UPON RETURNING AND GETTING BACK ON THE ROAD, I NOTICED MY CAR WAS PULLING BAD RIGHT AND THE STEERING WHEEL WAS SHAKING VERY BADLY. I MANAGED TO DRIVE IT THE ADDITIONAL 30 MILES BACK HOME. WHEN I STARTED THE TRUCK THE NEXT MORNING, THE STEERING WHEEL SHAKE WAS TOO BAD TO CONTINUE ANYWHERE BUT THE DEALERSHIP. I DROVE TO THE DEALERSHIP AND THEY SAID THAT THE TIRES WOULD BE COVERED UNDER MY EXISTING "BUMPER TO BUMPER" WARRANTY AS THE DEALERSHIP NOTICED THAT THERE WAS A HUGE BULGE IN THE TIRE WHICH WAS CAUSING ALL OF THE COMMOTION. UPON FURTHER INSPECTION, IT WAS NOTED THAT THE FRONT RIGHT TIRE ALSO HAD BULGES, THESE IN THE SIDEWALL WHERE THE TIRE MEETS THE RIM. THE DOT BATCH NUMBER IS #PJ6KA5IV 32/11 AND BOTH TIRES WERE FROM THE SAME BATCH. I WAS DRIVING AROUND WITH TWO DEFECTIVE TIRES!!!!!!! WITH MY 8 YEAR SON, 4 YEAR OLD SON, 3 WEEK OLD DAUGHTER AND MY WIFE. THIS IS UNACCEPTABLE! OUR LIVES WERE AT RISK! IMAGINE MY SURPRISE WHEN THE DEALERSHIP CALLED THE FOLLOWING MORNING AND SAID THAT GM HAD "CHANGED THEIR POLICIES AND THEY WOULD ONLY BE GIVING ME A 30% DISCOUNT." I UNDERSTAND POLICY BUT THESE TIRES ONLY MEASURED LITTLE WEAR AND SHOULD HAVE AT LEAST 55% MORE TREAD LIFE BASED ON THE EXACT TIRE MEASUREMENTS. INSTEAD, GM IS USING A SLIDING SCALE FOR MILEAGE THAT DOES NOT TAKE ACTUAL MEASUREMENTS INTO THEIR ASSESSMENT. SO NOW, I AM OUT $350 FOR 2 NEW TIRES THAT SHOULD HAVE LASTED A WHOLE LOT LONGER AND NO HELP FROM GOODYEAR OR GMC. *TR

  LOSS OF STEERING CONTROL (THREE EPISODES) : 13 NOV 2012, WHILE EXITING NB I-95 ONTO EB ROUTE 214 IN LANDOVER, MD, MY STEERING WHEEL LOCKED. MY SPEED AT THE TIME WAS APPROXIMATELY 50 MPH. I WAS ABLE TO BRAKE RAPIDLY AS THE RAMP BEGAN TO STRAIGHTEN FROM IT'S SWEEPING RIGHT CURVE. THE LOCKED STEERING WAS FORCING ME ONTO THE RIGHT SHOULDER. LUCKILY I WAS ABLE TO STOP MY TRUCK ON THE RIGHT SHOULDER BEFORE THE LOCKED STEERING FORCED ME OFF THE HARD TOP. DURING THIS EVENT, THE TRUCKS ENGINE REMAINED RUNNING AND THE IGNITION KEY STAYED TURNED ON. ONCE I WAS SAFELY STOPPED ON THE RAMP'S SHOULDER, I MADE ATTEMPTS TO TURN THE STEERING WHEEL. WITH BOTH OF MY HANDS ON THE WHEEL AND WHILE EXERTING A LOT OF UPPER BODY STRENGTH, I WAS ABLE TO BRAKE THE STEERING WHEEL FREE. YES, I DROVE THE CAR HOME FROM THAT POINT, A DISTANCE OF 16 MILES. EVERYTHING WITH THE STEERING APPEARED TO BE NORMAL, AGAIN. THIS PROBLEM APPEARS TO BE INTERMITTENT AND HAS NOW OCCURRED TO DATE, A TOTAL OF THREE TIMES. BETWEEN THE SECOND AND THIRD INCIDENT, THE TRUCK WAS TAKEN TO CAPITOL CADILLAC - GMC IN SUBURBAN MARYLAND WASHINGTON DC, FOR DIAGNOSIS OF THE PROBLEM. WHILE THE TRUCK WAS IN CAPITOLS POSSESSION, IT WAS DRIVEN 83 MILES BUT THE STEERING PROBLEM DID NOT PRESENT ITSELF. TWO DAYS AFTER RETRIEVING MY TRUCK FROM CAPITOL, THE STEERING BEGAN EXHIBITING A STRONG FEELING OF RESISTANCE AS IF IT WAS GOING TO FULLY LOCK, AGAIN. IT DID NOT HOWEVER. THE TRUCK IS SCHEDULED TO RETURN TO CAPITOL CADILLAC - GMC ON 20 NOV 2012. *TR

  2012 GMC DENALI. CONSUMER WRITES IN REGARDS TO VEHICLE STEERING PROBLEMS. *SMD THE CONSUMER NOTICED A VERY BAD PROBLEM WITH THE STEERING WHENEVER HE SLOWED DOWN TO TURN, HE WOULD LOOSE CONTROL OVER THE ABILITY TO TURN. THE WHEEL LOCKED DOWN WHEN HE APPLIED THE BRAKE AND TRIED TO TURN AT THE SAME TIME. HE WAS NOT ABLE TO TURN UNTIL HE PRESSED ON THE ACCELERATOR OR RELEASED THE BRAKE. THE DEALER SAID IT WAS CAUSED BY THE POWER BOOSTER TAKING ALL THE POWER TO THE BRAKES AND LEAVING VERY LITTLE TO THE STEERING. ALSO, THERE WAS A PROBLEM WITH THE BACK-UP SCREEN. THE PICTURE WAS EXTREMELY DARK, AND IT WAS HARD TO MAKE OUT THE IMAGES ON THE SCREEN. THE DEALER TRIED TO LIGHTEN THE SCREEN, BUT TO NO AVAIL.

  I PURCHASED A 2012 GMC SIERRA DENALI FROM STAHL MOTORS IN MONTEREY, CA IN FEBRUARY OF 2015. THEY ARE NOT WILLING TO PAY FOR THE DAMAGES TO MY TRUCK EVEN THOUGH THEY SOLD ME A COMPLETELY DANGEROUS VEHICLE, WHICH I WILL EXPLAIN. MY TRUCK DIDN'T FEEL RIGHT AS I WAS DRIVING SO I DECIDED TO TAKE IT TO A SHOP TO GET LOOKED AT. THERE IS A LONG LIST OF THINGS THAT IS WRONG WITH THE VEHICLE, BUT I WILL MENTION JUST THE MAIN ONES. THE TRUCK WAS SOLD TO ME WITHOUT THE REAR BRAKES HOOKED UP. THE BRAKE LINES FOR THE REAR CALIPERS WERE CAPPED OFF BY THE REAR DIFFERENTIAL. WHEN THE MECHANIC SHOP DISCOVERED THAT, THEY ALSO DISCOVERED THE MASTER CYLINDER WAS COMPLETELY DRY, WHICH CAUSED DAMAGE TO MY FRONT BRAKES. THERE WAS NO CROSS MEMBER UNDERNEATH THE VEHICLE FROM FRAME TO FRAME. IT WAS TORCHED OUT, THEREFOR LEAVING ZERO SUPPORT FOR THE FRAME OF THE TRUCK AS WELL AS THE FRONT DIFFERENTIAL. WHICH NEEDED TO BE REBUILT CAUSED FROM EXCESSIVE MOVEMENT LEFT TO RIGHT. FRONT DIFFERENTIAL NEEDED TO BE REBUILT CAUSED FROM THE DAMAGE OF NO CROSS MEMBER IN PLACE. BALL JOINTS WERE ALSO AFFECTED (ABOUT TO POP OUT OF CONTROL ARMS) DUE TO WRONG PARTS INSTALLED IN FRONT SUSPENSION OF VEHICLE.

  PURCHASE A NEW 2012 GMC SIERRA SLE ON 07/26/12. AS I LEAVE FOR WORK IN THE EARLY HOURS, IT REQUIRES THAT I USE THE DEFOG/DEFROST. ON THE MORNING OF THE 28TH I SELECTED THE DEFOG/DEFROST AND ONLY THE DRIVER'S SIDE CLEARED. THINKING IT MAY BE ISOLATED, I RECEIVED THE SAME RESULT ON THE 29TH. I CALLED THE SELLING DEALER ABOUT ANOTHER MATTER AND MENTIONED THIS PROBLEM. ON AUGUST 9TH THE TRUCK WAS TAKEN FOR SERVICE AND TO ADDRESS THIS ISSUE. WAS TOLD THAT IT IS OPERATING AS NORMAL AND THE DEALER TESTED TWO OTHER NEW TRUCKS. STILL NOT HAPPY WITH THE ANSWER, I CALLED GMC. THEY SETUP SERVICE AT ANOTHER DEALERSHIP FOR THE 16TH. AGAIN, NO PROBLEMS COULD BE FOUND PER THEIR TESTING, BUT WERE GOING TO CHANGE THE DUCT AS THE AIR FLOW WAS MUCH GREATER TO THE DRIVER'S SIDE. WHEN THE DUCT CAME IN, THEY OPTED NOT TO CHANGE IT, AS IT REQUIRES TO STRIP THE DASH TO THE WINDSHIELD. ALL THIS TIME GMC WAS UPDATED OF THE PROGRESS. THE SYSTEM DOESN'T CLEAR THE PASSENGER SIDE OF THE WINDSHIELD AND PASSENGER DOOR WINDOW. GMC STAND IS, THAT ENGINEERING DESIGN THE SYSTEM THIS WAY TO CLEAR THE DRIVER'S SIDE QUICKER DURING POOR WEATHER, AS LIKE SNOW AND ICE. MY STAND IS THAT THIS IS NOT A PROPER ANSWER FOR A VEHICLE MAKER TO STATE. THIS ISSUE MAKES THE VEHICLE UNSAFE TO OPERATE AND I DO NOT LIVE WITHIN AN AREA SEEING THIS TYPE OF WEATHER OFTEN. I HAVE READ MANY INTERNET ARTICLES RELATED TO THIS. OTHER OWNERS TRUCKS OPERATE PROPERLY CLEARING BOTH SIDES OR HAVE HAD THEM PROPERLY REPAIRED IF THEY HAVE HAD THE SAME ISSUE. I NEED TO HAVE MY VEHICLE REPAIRED SO THAT IT CAN BE OPERATED SAFELY. GMC WILL NOT ADMIT THAT THIS IS A PROBLEM REQUIRING REPAIRS. *TR

  OUR GMC HAS EXPERIENCED 3 EXTERIOR DOOR HANDLE FAILURES. WE PAID TO HAVE THE 1ST BROKEN HANDLE REPAIRED AS IT WAS NOT OPERABLE FROM THE OUTSIDE. THIS MAKES FOR A DANGEROUS EVACUATION EXPERIENCE IN THE EVENT OF AN EMERGENCY. WE CHOSE A NON-DEALER REPAIR FACILITY DUE TO THE COST OF USING A DEALER. THIS REPAIR HAS HELD UP WELL. SINCE THAT INITIAL REPAIR 2 MORE EXTERIOR HANDLES HAVE BECOME INOPERABLE. IT'S ONLY A MATTER OF TIME BEFORE THE 4TH AND FINAL HANDLE FAILS. THIS VEHICLE IS NO LONGER UNDER WARRANTY. HOWEVER, IT'S ONLY VERY LIGHTLY USED AND HAS LESS THAN 60K MILES ON IT. A 75% DOOR HANDLE FAILURE RATE IS UNACCEPTABLE BY ANYONE'S STANDARD. DUE TO THE COST OF THE REPAIRS WE HAVE NOT BEEN ABLE TO FIX THESE REMAINING 2 DEFECTIVE HANDLES. GMC, BBB AND NORTH COUNTY GMC IN ESCONDIDO, CA HAVE BEEN OF NO ASSISTANCE. WE ARE ALWAYS PREPARED TO PERFORM THE REQUIRED MAINTENANCE ON OUR VEHICLES. IN NO WAY IS THE REPAIR OF 3 DOOR HANDLES A "NORMAL" MAINTENANCE ITEM. THIS IS A SEVERE SAFETY HAZARD IN THE EVENT THE AN EMERGENCY EVACUATION IS REQUIRED. THERE IS NO WAY FOR 2 OF THE DOORS CAN BE OPENED FROM THE EXTERIOR OF THE VEHICLE. IT'S UNFORTUNATE GMC SEES THIS AS "DEFECTIVE" BUT IS NOT WILLING TO ASSIST IN THE REPAIRS. ALL 3 OF THE HANDLE BROKE WHILE TRYING TO GAIN ACCESS TO THE VEHICLE FROM THE OUTSIDE. THE VEHICLE WAS STATIONARY EACH TIME. ALL HANDLES ARE USABLE FROM THE INTERIOR OF THE VEHICLE. THE 2 UNREPAIRED HANDLES DO NOT WORK FROM THE EXTERIOR.

  They should be responsible for repairs or replacement of the cheap made frames that rust away so fast so u ain’t gotta worry about your truck fallling apart going down the rd and the lower control arms made of cast that rust from inside out and you don’t know until breaks while driving along with camber adjustments where they can throw alignment out with a single bump. Mostly the frame replacement is major always having to plate frame or check to make sure it will be able travel long trips or haul stuff in bed or a trailer with breaking or falling off truck causing wreck frame repair is major and time consuming if you don’t have proper stuff and definitely expensive and lower control arms that’ll make a wheel come real fast and it’s time consuming and expensive too but very dangerous and breaks and causes damage right then and there at high or low speed on highways or interstates

AFTER DOING SOME RESEARCH ONLINE IT LOOKS LIKE THERE HAS BEEN A MAJOR PROBLEM WITH GM TRUCKS WITH THE DURAMAX MOTOR FROM 2011-2016 AFTER THEY CHANGED THERE FUEL PUMP FROM THE CP3 HIGH VOLUME LOW PRESSURE PUMP TO THE CP4 HIGH PRESSURE LOW VOLUME PUMP. WHICH MEANS THE PUMP RUNS WITH LESS LUBRICATION WHICH RESULTS IN PUMP FAILURE, AND NOT JUST FAILURE BUT CATASTROPHIC FAILURE WHICH CAUSES MAJOR DAMAGE TO THE ENTIRE FUEL SYSTEM. I HAVE BEEN A LOYAL GM OWNER FOR OVER TWENTY YEARS, AND I AM EXTREMELY DISAPPOINTED THAT GM IS NOT WILLING TO MAKE IT RIGHT.
