2016 GMC Sierra 2500 complaints

THE 7 WAY TRAILER PLUG ON THIS VEHICLE WILL NOT HOLD THE TRAILER PLUG FIRMLY, RESULTING IN THE PLUG COMING LOOSE DURING NORMAL DRIVING CONDITIONS. ONE OBVIOUS ISSUE IS THAT THE FLAP HOLDING THE PLUG IN IS UPSIDE DOWN FROM ANY OTHER CONFIGURATION I'VE SEEN, ALLOWING THE PLUG TO SAG. THIS IS A SERIOUS SAFETY RISK AS I HAVE HAD SEVERAL INSTANCES WHERE LIGHTS AND EVEN THE TRAILER BRAKES HAVE STOPPED OPERATING WHILE IN TRANSIT , AFTER I GAVE VERIFIED THAT THEY WORKED WHEN I STARTED OUT. I THEN AM A HAZARD TO MY FELLOW MOTORISTS AND MY FAMILY. THIS TRAILER PLUG WORKED FLAWLESSLY WITH MY PREVIOUS TRUCK. GMS SOLUTIONS BLAME THE TRAILER OR PLUG, BUT GIVEN THE ORIENTATION OF THE PLUG AND THE NUMBER OF OWNERS THAT SEEM TO HAVE THIS ISSUE, I BELIEVE A BETTER SOLUTION SHOULD COME FROM THEM.

VIBRATION BETWEEN 65-80MPH. DEALER HAS ROAD FORCE BALANCED TIRES TWICE WITH NO BETTER RESULTS. FIRST TIME ONE TIRE WAS FOUND TO BE OUT OF SPEC THEN 2ND TIME, ALL FOUR ARE IN 'SPEC'. I DON'T BELIEVE THIS IS A TIRE/WHEEL PROBLEM AS THE VIBRATION VARIES ON SMOOTH HIGHWAY - AT TIMES IT IS VERY SMOOTH THEN IT WILL START VIBRATING/BOUNCING. VERY UNNERVING DRIVING AT THESE SPEEDS WITH A VIBRATION THAT FEELS LIKE A LOOSE WHEEL OR OTHER DRIVETRAIN PART. MY SON HAD A 2015 MODEL HE BOUGHT NEW AND HE FINALLY SOLD IT DISCLOSING THE ISSUE (STILL UNDER WARRANTY) RATHER THAN CONTINUING TO WASTE TIME WITH GM. PROBLEM HAS EXISTED SINCE I BOUGHT THE TRUCK NEW OCT. 2016. 2016 GMC SIERRA 2500HD DENALI 20" FACTORY WHEELS.

THESE HEADLIGHTS ARE HORRIBLE. VERY HARD TO SEE ON A WET DARK NIGHT, COMPARED TO THE 2009 GMC SIERRA 2500. COMPLAINED TO THE DEALER, FOUND A TSB FOR COMPUTER REFLASH TO TURN UP THE VOLTAGE TO THE BULB. MILD DIFFERENCE, BUT STILL NOT VERY GOOD FOR A $50K VEHICLE.

SUN GMC REFUSED TO FIX OUR AIRBAG RECALL BECAUSE WE DIDN'T BUY IT FROM THEM. THERE WAS A DISTURBANCE AFTER THE FACT. THEY NEW IS WARRANTIED WORK AND SENT US AWAY WITHOUT FIXING IT LEAVING US OPEN TO GETTING HURT. *TR

WHILE DRIVING AT 45MPH IN THE LEFT LANE OF A MAJOR CITY THOROUGHFARE THE ENGINE QUIT RUNNING, POWER STEERING AND BRAKES DID NOT WORK. THE CHECK ENGINE LIGHT CAME ON WHEN THE ENGINE QUIT RUNNING. I WAS ABLE TO GET THE VEHICLE STOPPED BUT THE ENGINE WOULD NOT START. THE VEHICLE WAS TOWED TO THE DEALERSHIP WHERE I WAS TOLD THIS ISSUE WAS REPORTED IN ARKANSAS, LOUISIANA AND TENNESSEE. THE DEALERSHIP REPORTED THAT SHARDS OF METAL WERE FOUND IN THE FUEL INJECTOR AND THE ENTIRE FUEL SYSTEM WOULD HAVE TO BE COMPLETELY REPLACED. ADDITIONALLY I WAS TOLD THE PARTS ARE HARD TO GET. THE VEHICLE WAS PURCHASED NEW AND WAS 7 MONTHS OLD AND HAD JUST OVER 7,000 MILES. THE VEHICLE IS STILL SITTING AT THE DEALERSHIP 10 DAYS LATER AND HAS NOT BEEN MOVED FROM WHERE IT WAS DELIVERED BY THE WRECKER SERVICE. GM HAS BEEN NOTIFIED BUT NO RESPONSE FROM GM OR DEALERSHIP MANAGEMENT YET AS TO WHAT CAUSED THE ENGINE FAILURE. I OCCASIONALLY TOW A FIFTH-WHEEL RV WITH THIS VEHICLE. I NO LONGER FEEL SAFE DRIVING THE VEHICLE AND WOULD NOT CONSIDER PURCHASING ANOTHER UNTIL A DETERMINATION IS MADE ON EXACTLY WHAT WENT WRONG.

REPORTING A CONDITION OF POOR ENGINEERING / PROTECTION REGARDING THE LOCATION OF THE TRANSMISSION OIL COOLER BEHIND THE FRONT BUMPER. THERE IS AN OPENING FOR COOLING FROM RAM AIR THAT PROVIDES NO PROTECTION FROM DEBRIS, ROCKS, BIRDS, ETC FROM DAMAGING THE FINS AND/OR THE COOLER ITSELF. IF AN EVENT OCCURS FROM ANY OR OTHER SITUATIONS ABOVE, IT WOULD BE POSSIBLE TO HAVE THE OIL LINES PUNCTURED RESULTING IN CATASTROPHIC FAILURE OF THE TRANSMISSION DUE TO LOSS OF FLUID WITH LITTLE TO NO WARNING TO THE DRIVER.
