2016 GMC SIERRA 1500 Complaints

WHEN THE PEDDLES ARE RAISED AND YOU STEP ON THE BRAKE YOU COULD BE PUSHING THE GAS AND BRAKE AT THE SAME TIME. WHEN THE PEDDLES ARE LOWERED THIS DOES NOT HAPPEN. A LOT OF PEOPLE STEP ON THE SIDE OF THE BRAKE AND IT HAPPENS ONLY WHEN RAISED.

PERIODICALLY 3 TIMES A WEEK, WHILE DRIVING, THE STABILIZTRAK ILLUMINATES AND DRIVABILITY DECLINES, ENGINE CHECK LIGHT ILLUMS, THE GEAR REMAINS IN A LOW GEAR WITHOUT SHIFTING. TURN THE IGNITION OFF FOR A COUPLE SECONDS AND IT CLEARS AND THE ENGINE LIGHT GOES OUT AFTER 25-35 MILES. SOMETIME IT DOESN'T RESET AFTER 3 ATTEMPTS OF TURNING OFF AND ON THE IGNITION. THE CODES ARE P0700 A U0100 WITH OTHERS WHEN DEALERSHIP ANALYZED. THREE TIMES IT WAS IN THE GMC SHOP AND THREE TIMES GIVING BACK AND PROBLEM STILL EXISTED. I RECORDED ON VIDEO AND GAVE IT TO THE DEALERSHIP AS PROOF.

THE DRIVER SEAT DOES NOT GO UP AND DOWN.THIS IS A BIG SAFETY FEATURE PURCHASED NEW I CAN BARLEY SEE OVER STEERING WHEEL WHY WOULD YOU MAKE SEATSLIKE THIS

ELECTRICAL ISSUE CAUSING SOUND SYSTEM, REAR CAMERA AND RADIO TO SHUT DOWN COMPLETELY. ISSUE STARTED 2 WEEKS AFTER PURCHASE. VEHICLE HAS BEEN SERVICE SEVERAL TIMES BUT ISSUE HAS NOT BEEN RESOLVE.

THE QUALITY/PRECISION ISSUES I AM HAVING WITH MY VEHICLE ARE ISSUES THAT SHOULD NOT BE HAPPENING TO A $50,000 VEHICLE. THE ENGINE HAS A ROUGH IDLE WHEN IT IS FIRST STARTED UP. AFTER THE VEHICLE WARMS UP THE ROUGH IDLE GETS WORSE. IT GETS EVEN WORSE WHILE I AM DRIVING IT AND I COME TO A STOP SIGN OR RED LIGHT. THE ROUGH IDLE VIBRATES THE ENTIRE VEHICLE. THE ROUGH IDLE IS AT ITS WORSE WHEN I STOP AFTER HAVING DRIVEN ON THE HIGHWAY FOR SEVERAL HOURS. I BOUGHT THIS NEW VEHICLE BECAUSE MY PREVIOUS VEHICLE WAS TOTALED IN AN AUTOMOBILE ACCIDENT WHEN SOMEONE T-BONED ME IN MY 2007 GMC YUKON XL. MY YUKON HAD APPROXIMATELY 200,000 MILES AND DID NOT HAVE A ROUGH IDLE OR VIBRATE LIKE MY 2016 SIERRA DOES. I KNOW THE TECHNOLOGY IS TOTALLY DIFFERENT THAN MY 2007 BUT IT SHOULD AT LEAST IDLE AS GOOD AS IF NOT BETTER THAN MY 2007 YUKON THAT HAD 200,000 MILES, BUT IT DOES NOT. THERE IS ALSO A HESITATION WHEN ACCELERATING FROM A STOP THAT IS GETTING WORSE WITH EVERY ADDITIONAL MILE I PUT ON THE VEHICLE. THE HESITATION IS SO BAD AT TIMES I WORRY THE ENGINE IS GOING TO STALL OUT ON ME. IT FEELS/SOUNDS LIKE THE CYLINDERS ARE LOADING UP WITH TOO MUCH FUEL AND ARE NOT FIRING CORRECTLY. THE STOICHIOMETRIC RATIO IS NOT CORRECT. AT TIMES, IT FEELS LIKE A MISS. MY FUEL MILEAGE IS ALSO DECREASING. IN THE VERY BEGINNING I WAS AVERAGING AROUND 19 MILES PER GALLON AND NOW I AM AVERAGING AROUND 17 MILES PER GALLON. I HAVE TRIED DIFFERENT OCTANE LEVELS OF MOSTLY SUNOCO AND BP FUELS WITH NO NOTICEABLE CHANGE IN FUEL MILEAGE OR ENGINE PERFORMANCE EXCEPT FOR THE ABOVE-MENTIONED CONDITIONS GETTING WORSE. I AM WORRIED THIS RICH MIXTURE WILL CAUSE PREMATURE FAILURE OF THE CATALYTIC CONVERTER AND O2 SENSOR. I AM ALSO CONCERNED THE EXCESS CARBON COULD BUILD UP AROUND THE VALVES CAUSING ADDITIONAL PROBLEMS DOWN THE ROAD AFTER THE WARRANTY EXPIRES.

I PURCHASED MY 2016 GMC SIERRA SLE DOUBLE CAB ON 9/13/2016. MY TRUCK BEGINS TO VIBRATE/SHAKE AT 40 MPH AND GETS PROGRESSIVELY WORSE TO 70 MPH. THE SHAKE CAN BE FELT IN THE DRIVERS SEAT AND FLOOR. THE CENTER CONSOLE SHAKES AND SHUDDERS MAKING ME FEEL NAUSEOUS AND DIZZY WHILE DRIVING AT HWY SPEEDS. I RETURNED THE TRUCK TO THE DEALER WITHIN THE FIRST 500 MILES. THE WHEELS AND TIRES WHERE FORCED BALANCED WITH NO RELIEF AND THEN ALL FOUR TIRES WERE REPLACED. THE WHEELS AND TIRES I PURCHASED WITH THE VEHICLE WERE A DEALER ADD OF GM 22" WHEELS AND TIRES. THE VIBRATION WAS NOT AS APPARENT AFTER THE NEW TIRES WERE PUT ON BUT NOW THAT I HAVE PUT AN ADDITIONAL 1700 MILES ON THE TRUCK, THE VIBRATION AND SHAKE IS BACK AS ORIGINALLY REPORTED. DURING A 3 HOUR ROAD TRIP ON 11/2/2016 I HAD TO STOP AND LET MY PASSENGER CONTINUE THE TRIP BECAUSE I WAS ILL FROM THE SHAKING AND VIBRATIONS. MY SALES PERSON INITIALLY TOLD ME THAT WHAT I WAS EXPERIENCING WAS HOW 22" WHEELS FEEL. I HAD A 2012 SILVERADO LT Z71 AND A 2014 SILVERADO LT THAT HAD LARGE WHEELS AND I DID NOT HAVE. ANY SHAKING OR VIBRATIONS. I HAVE MADE ANOTHER APPOINTMENT WITH ANOTHER DEALER TO SEEK RELIEF. *TR

THE 2016 GMC SIERRA HAS A CONSTANT VIBRATION WHICH IS FELT THROUGH THE SEATS AND THE STEERING WHEEL. THE CONDITION IS IDENTICAL TO THOSE SUBMITTED FOR THE 2014 AND 2015 GMC AND CHEVROLET MODELS

A WEEK AFTER PURCHASING MY NEW 2016 GMC SIERRA DENALI 1500 SHORT BED I BEGAN NOTICING A STRONG VIBRATION/SHAKE THAT COULD BE FELT WHILE IN MOTION AT HIGHWAY SPEEDS BETWEEN 75-80MPH. THE FLATTER THE ROAD THE STRONGER THE VIBRATION CAN BE FELT AT THESE SPEEDS. I HAVE BROUGHT IT IN TWICE TO THE DEALERSHIP I BOUGHT IT FROM AND ONCE TO ANOTHER DEALERSHIP YIELDING NO FIX TO THE PROBLEM. ACTUALLY, I HAVE BEEN TOLD THERE IS NO PROBLEM AND THAT IS HOW THE TRUCK RIDES. I HAVE ALSO BEEN TOLD MY EXPECTATIONS FOR A PICKUP TRUCK "UNREALISTIC." WHEN THE FRONT AND PASSENGER SEATS PHYSICALLY SHAKE AT THE SPEEDS MENTIONED I FIND IT VERY HARD TO BELIEVE THAT THERE IS NO ISSUE WITH THE VEHICLE AND THAT MY EXPECTATION SHOULD BE CONSIDERED UNREALISTIC. DRIVING THE TRUCK LONG DISTANCES ON THE HIGHWAY IS UNPLEASANT AT BEST CREATING AT TIMES FEELINGS OF NAUSEA. I HAVE ZERO CONFIDENCE THE ISSUE WILL BE ADDRESSED, BUT WANTED TO AIR MY COMPLAINT FOR OTHER POTENTIAL BUYERS. THIS TRUCK IS SUPPOSED TO BE THE TOP OF THE LINE AND I ABSOLUTELY REGRET BUYING IT WITH THIS PERSISTENT PROBLEM PRESENT THAT NOBODY WANTS TO ADDRESS.

TL* THE CONTACT OWNS A 2016 GMC SIERRA 1500. WHEN THE SHIFTER WAS ENGAGED, THE VEHICLE DID NOT REGISTER THE CORRECT GEAR AND FAILED TO MOVE. WHEN THE VEHICLE DID RECOGNIZE THE CORRECT GEAR, IT ACCELERATED UNINTENTIONALLY. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE TRANSMISSION WAS DEFECTIVE AND PARTS IN THE TRANSMISSION NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED; HOWEVER, THE FAILURE RECURRED. THE VEHICLE WAS RETURNED TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE TRANSMISSION NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 150. UPDATED 10/18/16*LJ *TR

ONE DAY THE POWER STEERING WOULDN'T WORK AT ALL FOR SEVERAL TRIPS. I WOULD TURN THE TRUCK ON AND A SERVICE WARNING MESSAGE WOULD DISPLAY STATING "HAVE YOUR POWER STEERING SERVICED" THE NEXT DAY THE POWER STEERING QUIT WORKING WHILE IN THE MIDDLE OF A TURN. RECEIVED THE SAME WARNING AS I RECEIVED SEVERAL TIMES THE DAY BEFORE.
