2017 GMC Sierra

THE VEHICLE EXHIBITS VIBRATIONS THAT CAN BE RATHER EXTREME AT TIMES. IT SEEMS TO BE MOST NOTICEABLE IN THE 70-75 MPH RANGE BUT CAN SOMETIMES BE FELT AT OTHER SPEEDS. IT FEELS LIKE THE VIBRATION ORIGINATES FROM THE REAR OF THE VEHICLE. TWO DEALERSHIPS HAVE REPLACED MULTIPLE PARTS AND HAVE PERFORMED NUMEROUS ALIGNMENTS AND ROAD FORCE BALANCES BUT CAN NOT IDENTIFY/REMEDY THE PROBLEM. THERE ARE THOUSANDS OF COMPLAINTS ON MULTIPLE ONLINE FORUMS OF THIS SAME ISSUE FOR 2014-2015 GM 1500 SERIES PICKUP TRUCK. SO FAR THERE HAS BEEN NO FIX FOR THEM EITHER. GM TREATS IT AS AN ANNOYANCE IN THE COMFORT OF THE RIDE, HOWEVER IF THEY CAN NOT IDENTIFY THE ISSUE HOW DO THEY KNOW IT IS NOT A SAFETY RISK.

WE WERE DRIVING UP A SLIGHT INCLINE IN A PARKING GARAGE WHEN THE ENGINE STARTED SPUTTERING AND SHUT OFF. AFTER SEVERAL ATTEMPTS IT STARTED AND WE WERE ABLE TO MAKE IT TO A PARKING SPACE WITH THE ENGINE STILL SPUTTERING. I RECEIVED A NOTIFICATION FROM THE TRUCK, DECREASED ENGINE POWER. THE NEXT DAY I BROUGHT IT TO BE CHECKED BY THE LOCAL GMC DEALER. THEIR DIAGNOSIS IS VAPOR LOCK WHEN THE FUEL PUMP GETS NEAR OR OVER 100 DEGREE. ITS MY OPINION THAT GMC PLACED A FAULTY PART WHEN MANUFACTURING THE VEHICLE. I WOULD LIKE THIS TO BE CONSIDERED FOR RECALL.

MY WINDSHIELD WIPER FLUID ONLY SPRAYS OUT 30% OF THE TIME. USUALLY IN THE MORNING THEN ANY OTHER TIME OF THE DAY IT WILL NOT SPRAY OUT. THEY REPLACED THE PUMP AND THAT DID NOT FIX IT AND THEY WON'T DO ANYTHING ELSE AND NOW IT IS OUT OF WARRANTY. WHEN RUNNING LOWER RPMS DRIVING THE TRUCK IT BEGINS TO FEEL LIKE ITS SHAKING FORWARD AND BACKWARDS, LIKE A SHUDDERING FEELING. I HAVE READ ABOUT OTHER PEOPLE HAVING THIS PROBLEM AND IT DESCRIBES MINE PERFECTLY. I HAVE THE 8SPEED

TL* THE CONTACT OWNS A 2017 GMC SIERRA 1500. WHILE THE VEHICLE WAS IDLING AT A TRAFFIC LIGHT, IT BEGAN TO RATTLE. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS TAKEN TO FRESNO BUICK GMC (LOCATED AT 5515 N BLACKSTONE AVE, FRESNO, CA 93710, (559) 742-4113) WHERE AN UNKNOWN DIAGNOSIS AND REPAIR WERE PERFORMED; HOWEVER, THE FAILURE CONTINUED. THE MANUFACTURER WAS NOT NOTIFIED. THE FAILURE MILEAGE WAS 24,000.

AS I WAS BACKING UP I APPLIED MY BRAKES AND FOR SOME REASON NOTHING HAPPENED WHICH RESULTED IN MY HITTING MY WIFE'S CAR AND DAMAGING HER DRIVERS SIDE QUARTER PANEL. WHEN I ASKED GMC ABOUT THE ISSUE THEY SAID IT WAS JUST AN ERROR ON MY PART. NOW I FIND OUT THAT THERE IS A RECALL ON THE BRAKING SYSTEM THAT THE PRESSURE TO THE BRAKES MAY BE AFFECTED. WHO IS RESPONSIBLE FOR THE DAMAGE TO HER CAR?

SINCE DECEMBER OF 2017 THE TRANSMISSION, WHEN COLD, AT APPROX. 25 MPH AND AT 40-44 MPH WHEN NEUTRAL THROTTLE IS APPLIED, BANGS BETWEEN GEARS FORCING THE OPERATOR TO EITHER ACCELERATE OR DECELERATE SO THE CONDITION WILL CEASE. IF THERE IS NO CHANGE BY THE OPERATOR, IT FEELS AS IF THE TRANSMISSION WILL BREAK THE U-JOINTS IN THE DRIVELINE OR BLOWOUT THE REAR-END GEARS. I HAVE MADE NUMEROUS ATTEMPTS WITH GMC TO REMEDY THE ISSUE TO NO AVAIL. THE VEHICLE HAS BEEN IN THE DEALERSHIP IN EXCESS OF 40 DAYS FOR THE SAME PROBLEM WITH NO RESOLUTION
