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.

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. THE ONLY ONE THAT KNOWS THE ACTUAL NUMBER OF PUMPS THAT HAVE FAILED IS THE MANUFACTURERS, WHO WILL NOT SHARE THAT INFORMATION WILLINGLY. *JS

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

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

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
