  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

  THE GMC SIERRA 3500HD WHILE IN REGENERATION MODE FUNNELS EXHAUST DIRECTLY INTO THE CAB THROUGH THE VENTS. WHILE GM RECOGNIZED THIS AS A FLAW AND CAME UP WITH A FIX FOR IT, THEY WILL ONLY REPAIR IT IN A 5 YEAR OR 100,000 MILE WINDOW. HOW IS THIS NOT A SAFETY ISSUE WITHOUT AN EXPIRATION?

• 09/01/2015· SUSPENSION,POWER TRAIN,SERVICE BRAKES

  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.

• 08/23/2012· VISIBILITY/WIPER

  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

• 08/20/2015· ELECTRICAL SYSTEM

  WHILE MOVING WITH TRANSMISSION IN DRIVE, THE IGNITION SWITCH CAN BE SWITCHED OFF. BY DOING SO, THE POWER STEERING AND BRAKES FAIL TO FUNCTION PROPERLY. THE STEERING WHEEL WILL LOCK, NOT ALLOWING TO STEER. THERE HAVE BEEN A SAFETY CONCERNS WITH OTHER GM PRODUCTS, WHY NOT THIS MODEL? THIS IS A SAFETY CONCERN.

• 08/07/2015· STRUCTURE

  FRAME COATING IS PEELING OFF THE BACK OF THE FRAME AND IN OTHER AREAS. EXCESSIVE RUST FOR A VEHICLE THAT IS 3 YEARS OLD IN A TEMPERATE CLIMATE. ONLY APPEARS TO BE AFFECTING FRAME COVERED WITH WAXY UNDERCOAT. VERY LITTLE RUST AND NO PEELING ON AREAS THAT HAVE OTHER PAINTS/COATINGS.

  PULLING INTO A PARKING SPOT IN A PARKING GARAGE GOING NO MORE THAN 3 MILES PER HOUR, OR HOWEVER FAST THIS VEHICLE CAN GO WHILE FOOT IS RESTING ON BRAKE, GETTING READY TO FULLY BRAKE. AS I PRESSED DOWN ON BRAKE TO STOP, THE VEHICLE CONTINUED AS IF THE ANTI-LOCK BRAKE SYSTEM SLIPPED, CAUSING THE TRUCK TO DRIVE FORWARD CRASHING THROUGH THE SHEETROCK WALL AND FINALLY STOPPING AFTER HITTING THE GLASS WINDOWS. TWO WEEKS LATER, AFTER ALL COSMETIC REPAIRS WERE DONE, THE VEHICLE DID THE SAME THING IN ANOTHER PARKING LOT, BUT LUCKILY BROKE BEFORE HITTING THE CURB AND LIGHT POST. I DID FEEL UNDER MY FOOT ON THE BRAKE PEDDLE, AS I PRESSED DOWN TO STOP, A SLIP OF SOME SORT WHICH AT THE SAME TIME CAUSED THE VEHICLE TO PUSH FORWARD RIGHT BEFORE STOPPING. THIS IS DEFINITELY A MALFUNCTION OF SOME SORT WITH THE ANTI-LOCK BRAKE SYSTEM. *TR

  CHECK ENGINE LIGHT ILLUMINATED. TOOK TRUCK TO LOCAL CHEVROLET DEALER FOR REPAIR AND THEY DISCOVERED THE WIRES HAD BEEN CHEWED THROUGH. I READ THAT GM USES PEANUT OIL ON WIRES IN ORDER TO INSTALL THEM EASIER. LOOKS LIKE THIS ATTRACTED A MOUSE, SQUIRREL, CHIPMUNK, OR OTHER CREATURE AND IT CHEWED THE WIRES. LUCKILY IT DID NOT AFFECT THE OPERATION OF THE TRUCK BUT IT COULD HAVE LED TO A SHORT CIRCUIT THAT COULD HAVE CAUSED A FIRE. I FEEL THIS NEEDS TO BE THOROUGHLY INVESTIGATED. AND GM NEEDS TO CREATE SOME KIND OF ANIMAL REPELLANT TO SPRAY ON THE WIRES AFTER VEHICLE ASSEMBLY.

  THIS STARTED JUST A FEW WEEKS AFTER I PURCHASED THE TRUCK, STILL UNDER WARRANTY. IT HAS BEEN IN THE SHOP TWICE FOR THIS. IT HAS HAPPENED 3 TIMES. WHILE DRIVING THE TRUCK WILL SHUT OFF LIKE YOU TURNED THE KEY OFF. VERY DANGEROUS WHEN DRIVING IN TRAFFIC. HAS BEEN IN SHOP TWICE FOR THIS PROBLEM, GMC HAS FAILED TO FIND OR FIX THE PROBLEM. I TOLD THEM THAT I WOULD NOT PUT MY FAMILY BACK INTO A TRUCK THAT HAS THE POSSIBILITY OF CAUSING A WRECK AND GETTING THEM HURT. FILED A CLAIM [XXX] WITH GMC CUSTOMER SERVICE, TRYING TO GET SOME HELP. NOTHING HAPPENED. THE GMC SERVICE CENTER TOLD ME THAT THEY COULD NOT FIND OR FIX THE PROBLEM, AND THAT I NEEDED TO PICK UP MY TRUCK. I TOLD THEM THAT IF THEY COULD NOT FIND OR FIX THE PROBLEM, I WOULD NOT PUT MY FAMILY BACK INTO AN UNSAFE TRUCK THAT COULD POSSIBLY GET THEM HURT OR KILLED. I TRIED TO HAVE SOMEONE FROM GMC UPPER MANAGEMENT CONTACT ME SO WE COULD COME UP WITH A SOLUTION. BUT NO ONE FROM MANAGEMENT WOULD CONTACT ME. SO I ENDED UP HAVING TO TRADE THIS TRUCK IN FOR A NEW ONE, WHICH COST ME MONEY OUT OF MY POCKET, HIGHER PAYMENTS, LONGER TERMS ETC. DON'T THINK IT WAS RIGHT THAT GMC WOULD NOT STAND BEHIND THERE PRODUCT. WHY IS IT THAT GMC DID NOT HAVE TO DO ANYTHING ABOUT A SAFETY ITEM THAT THEY COULD NOT FIX ? I WAS NOT ASKING FOR MONEY OR ANYTHING LIKE THAT, JUST SWAP IT OUT EVEN FOR A SAFE TRUCK THAT I COULD PUT MY FAMILY IN WITHOUT FEAR OF THEM GETTING HURT. BUT INSTEAD, GMC DECIDED TO FORGET ABOUT THE PROBLEM, AND IT ENDED UP COSTING ME AND MY FAMILY MONEY THAT COULD HAVE BEEN USED FOR OTHER THINGS LIKE FOOD, BILLS, MEDICAL ETC.

  THE FUEL INJECTION PUMP CP4 HAD A CATASTROPHIC FAILURE AS I WAS DRIVING ON A HEAVILY TRAVELED FOUR LANE HIGHWAY, US RT.20. I LOST POWER STEERING AND BRAKES. I FELT FORTUNATE THAT I WAS NOT TOWING A 16,000 LB. FIFTH WHEEL CAMPER DOWN A MOUNTAIN ROAD.I SAY THIS BECAUSE IT WAS EXTREMELY DIFFICULT TO MAINTAIN CONTROL OVER THE TRUCK STEERING IT AND BRINGING IT TO A CONTROLLED STOP. I HAVE READ ABOUT THESE PUMPS FAILING ON NUMEROUS DIESEL FORD AND GM TRUCKS. I ALSO FEEL IF A WOMAN OR SMALL PERSON HAD THIS HAPPEN TO THEM THE OUTCOME COULD END IN LOSS OF CONTROL RESULTING IN INJURIES EVEN DEATHS.

  Our Dash board cracked very badly from the top next to the speaker to the passenger side air bag. We purposely use a dash board cover and never place heavy things on it. This is a safety issue as if getting in an accident wouldn’t be bad enough flying shrapnel would be worse. We just had it fixed at a dealership to the tune of $2500. This is not okay as I see this is a constant problem.

  APPARENTLY GM USES PEANUT OIL TO LUBRICATE WIRING SO THEY CAN MORE EASILY INSULATE, ETC (ACCORGING TO THE GM DEALER). THIS ATTRACTS RATS AND MICE WHICH CHEW UP THE WIRING - POTENTIALLY IMPACTING SENSORS AND OTHER ITEMS CONTROLLING CRUISE, STABILITY/TRACTION CONTROL, AND ANY NUMBER OF ELECTRICAL SYSTEMS THAT THE DRIVER MAY BE RELYING UPON FOR SAFETY. I ACTUALLY HAD MAP SENSOR WIRES CHEWED UP THAT DISABLED MY STABILITY/TRACTION SYSTEMS AND INHIBITED ENGINE PERFORMANCE. LUCKILY FOR ME IT HAPPENED IN MY DRIVEWAY RATHER THAN ON THE HIGHWAY. DEALER CLAIMS IT IS NOT WARRANTY ITEM EVEN THOUGH CAUSED BY A PROCESS THAT GM ELECTS TO USE IN BUILDING THE VEHICLE. THIS COULD IMPACT ANY/EVERY VEHICLE THAT GM BUILDS WITH USE OF PEANUT OIL (MAY INDEED BE ALL OF THEIR MODELS). *TR
