NHTSA Complaint #11291983 — 2017 GMC SIERRA

WHILE OPERATING VEHICLE ON HIGHWAY, I EXPERIENCE A SHAKE/SHUDDER WHEN AT SPEEDS OF 50 MPH AND HIGHER. VEHICLE WAS TAKEN TO DEALER STATED THAT THE TORQUE CONVERTER DID SHUDDER. DEALER CHANGED TRANSMISSION FLUID AND I WAS ADVISED TO DRIVE FOR 200 MILES TO SEE IF PROBLEM WAS CORRECTED. SHUDDER STILL REMAINS AND NOW THE VIBRATION IS CONSTANT AT 70 MPH. I CALLED DEALER AGAIN WHO SAID THAT IT WAS PROBABLY A TIRE BALANCE ISSUE. I ARGUED WITH THEM AND STATED I HAD NO SUCH ISSUE BEFORE FIRST BRINGING VEHICLE IN. DEALER IS SETTING UP APPOINTMENT FOR ME TO TAKE IN AGAIN. VIBRATIONS HAVE LITERALLY CAUSED MY 6 YR OLD DAUGHTER TO VOMIT ON 3 DIFFERENT OCCASIONS WHEN IN THE VEHICLE. SHE HAS ONLY BEEN IN VEHICLE 5 OR 6 TIMES. VEHICLE FEELS UNSAFE AT HIGHWAY SPEEDS. I HAVE READ MANY FORUMS ONLINE STATING THIS ISSUE IS ON MANY VEHICLES GM HAS MADE. I AM CURIOUS AS TO WHEN GM WILL BE MANDATED TO TAKE CORRECTIVE ACTION OR BUY THE VEHICLES BACK FROM THE OWNERS.
