2017 GMC SIERRA 1500 Complaints

STOPPED AT A STOPLIGHT, NO PROBLEM. AFTER A FEW SECONDS TRUCK STARTED TO ROLL FORWARD. HAD TO APPLY TREMENDOUS PRESSURE ON BRAKE TO STOP VEHICLE. PROBLEM CONTINUED UNTIL I WAS ARRIVED AT DESTINATION A QUARTER MILE AWAY. OCCURRED SEVERAL MORE TIMES. CUT VEHICLE OFF AND WHEN RESTARTED IT OCCURRED ONCE AND THEN RETURNED TO NORMAL OPERATION.

THE TRUCK LURCHES FORWARD AS IF THE ACCELERATOR IS BEING DEPRESSED WHILE COMING TO A STOP OBVIOUSLY WHILE DEPRESSING THE BRAKE. THIS CAUSES DANGEROUS SITUATIONS EVERY DAY IN TRAFFIC. I HAVE NOT FOUND ANY SOLUTIONS TO THE PROBLEM ONLINE. REPROGRAMMING COMPUTER AND REPLACING OTHER SPEED CONTROL MODULES HAS NOT SOLVE THE PROBLEM FOR OTHER DRIVERS.

8 SPEED TRANSMISSION IS DANGEROUS. UNDER LIGHT THROTTLE, THE VEHICLE WILL MAKE A LOUD POPPING NOISE AND LURCH FORWRWARD. LIKE STOPPING AT A STOP LIGHT, DRIVING THROUGH A DRIVE-THRU. MY TRUCK WILL SHAKE VIOLENTLLY.. DEALER SAYS ITS THE TRANSMISSION. WHEN I TRY TO ENTER MY GARAGE THE TRUCK WILL SORT OF JUMP FORWARD. DELEAR SAYS ITS TORQUE CONVERTER SUTTER. TRANSMISSION HAS BEEN WORKED ON 3 TIME. IT SEEMS TO GET WORSE. DELEARS SAYS THE 8 SPEED TRANSMISSION HAS MANY ISSUES BUT GM DOES NOT HAVE A FIX. THESE 8 SPEED TRANSMISSIONS WILL END UP KILLING FOLK.. THIS STUFF HAPPENS ON A DAILY BASIS

TL* THE CONTACT OWNS A 2017 GMC SIERRA 1500. WHILE ATTEMPTING TO ACCELERATE, THE ACCELERATOR PEDAL TRAVELED ALL THE WAY DOWN TO THE FLOORBOARD. THE CONTACT STATED THAT THE ENTIRE BRACKET THAT HELD THE PEDAL COLLAPSED. THE CONTACT STATED THAT THE FAILURE OCCURRED EVER SINCE THE VEHICLE WAS PURCHASED IN MAY OF 2017. THE VEHICLE WAS TAKEN TO WALKER BUICK GMC (1616 MACARTHUR DR, ALEXANDRIA, LA 71301) ON THREE OCCASIONS. THE DEALER REPLACED THE BRACKET ONCE, BUT THE FAILURE RECURRED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 35,601.

MY TRUCK SHIFTS VERY HARD BETWEEN GEARS, ESPECIALLY 1ST TO 2ND. FEELS LIKE GETTING REAR ENDED SOMETIMES. IT ALSO HESITATES DAILY WHEN BACKING OUT OF MY DRIVEWAY AND PUTTING IT FROM REVERSE TO DRIVE. YOU DON'T KNOW WHEN IT WILL ACTUALLY ENGAGE MAKING IT DANGEROUS WHEN PULLING OUT INTO THE STREET. ITS DEFINITELY AN ISSUE WITH THE TRANSMISSION BUT NO FIXES OFFERED FROM DEALER YET.

TL* THE CONTACT OWNS A 2017 GMC SIERRA 1500. THE CONTACT STATED THAT WHILE ATTEMPTING TO BRAKE, THE BRAKE PEDAL WAS STIFF AND VERY DIFFICULT TO DEPRESS. THE CONTACT MENTIONED THAT THE ABS IN THE BRAKES WAS VIBRATING. THE VEHICLE WAS NOT TAKEN TO A DEALER OR INDEPENDENT MECHANIC FOR DIAGNOSIS OR REPAIRS. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 32,000.

TAKA RECALL WIRELESS CHARGER ON CONSOLE DOES NOT WORK WITH SMART PHONES ONLY ON A VERY SELECT FEW THAT ARE OUT OF DATE MY PHONE BEING THE GALAXY NOTE 9, AND MY FIANCEE'S PHONE IPHONE XR DO NOT CHARGE AND FRANKLY THE MONEY YOU PAY FOR THIS TRUCK TO HAVE AN ACCESSORY OPTION NOT WORK IS RIDICULOUS

"HAVE TAKEN MY 2017 GMC SIERRA INTO THE DEALERSHIP TWICE FOR TRANSMISSION ISSUES, THE LAST TIME WAS A MONTH AGO. BOTH TIMES I WAS TOLD THAT THERE WASN'T ANYTHING WRONG BUT THAT THE TRANSMISSION SOFTWARE WAS 'RE-FLASHED' AND THAT THE TRANSMISSION WOULD HAVE TO 'RE-LEARN MY DRIVING HABITS'. MY TRUCK IS STILL HAVING PROBLEMS. WHILE UPSHIFTING FROM 1ST TO 2ND GEAR, THE TRANSMISSION SOMETIMES HESITATES BEFORE IT ENGAGES AND THEN CAUSES THE TRUCK TO LUNGE FORWARD WITH A HUGE SLAM. WHILE DOWNSHIFTING FROM 2ND TO 1ST GEAR, THE TRANSMISSION WILL MAKE A VERY NOTICEABLE 'CLUNK'. I'M ABOUT TO TAKE IT BACK A 3RD TIME. THIS IS EXTREMELY FRUSTRATING MY BOUGHT MY TRUCK LESS THAN 2 YEARS AGO AND IT ONLY HAS 25,000 MILES."

THE BRAKE PEDAL BECOMES EXTREMELY STIFF WHEN TRYING TO STOP AT SLOW SPEEDS, ESPECIALLY IN PARKING LOTS. THE VEHICLE BECOMES VERY DIFFICULT TO STOP ALMOST CAUSING CRASHES. GM DEALERSHIP REPEATEDLY TESTS VEHICLE AND TRIES TO CLAIM THERE IS NOTHING WRONG AND I'M MAKING A MISTAKE. HAD TO TAKE VEHICLE IN SEVERAL TIMES AND EVENTUALLY THEY FOUND A FAILED VACUUM PUMP. THEY TRIED TO MAKE ME PAY $700+ FOR THE REPAIR EVEN THOUGH ITS A KNOWN ISSUE. THEY ARE TRYING TO AVOID DOING A RECALL AND PUTTING THEIR BOTTOM LINE AHEAD OF SAFETY. THESE TRUCKS ARE DANGEROUS.

THE BRAKES ARE NOT WORKING AT SLOW SPEEDS. I WAS PARKING IN A PARKING GARAGE WHILE PULLING UP TO THE CONCRETE WALL AND PUSHING ON THE BRAKE THE TRUCK ALMOST DIDN'T STOP AND THE PEDAL GOT VERY STIFF. WHILE DRIVING HOME IN TRAFFIC THE TRUCK DID THE SAME THING AND I ALMOST HIT THE CAR IN FRONT OF ME. IT SEEMS TO BE AT SLOWER SPEEDS AND THE BRAKES ARE LOSING ALL POWER. THE TRUCK IS ONLY 2 YEARS OLD AND NORMALLY STOPS ON A DIME. TOOK TO THE DEALER TODAY, AND THEY SAID THE VACUUM PUMP IS BAD AT ONLY 39,000 MILES.
