Consumer Description

SEVERE TRANSMISSION SHUDDER. LAST MONTH HAD TAKEN MY 2020 CHEVROLET SUBURBAN TO THE WEST CHEVROLET DEALER LOCATED IN ALCOA, TENNESSEE. I WAS ADVISED BY A TECH THAT THE VEHICLE NEEDED A NEW TORQUE CONVERTER. I PAID 2,200.00 FOR THIS REPAIR. THIS REPAIRS DID NOT FIX THE ISSUE. AFTER PAYING MY BILL AND DRIVING THROUGH THE PARKING LOT, IT STARTED BACK IMMEDIATELY. THE TECHNICIAN ADVISED THEIR WAS NOTHING ELSE THEY COULD DO AFTER EXPRESSING HOW BIG OF A SAFETY CONCERN IT. SO I ATTEMPTED TO DRIVE IT HOME. AS I ENTEREDED INTO A BUSY 4 LANE HIGHWAY (ALCOA HIGHWAY) THE VEHICLE WOULD MOVE AND BEGAN SHUDDER VERY BAD, ALMOST CAUSING A CRASH. AFTER DOING LOTS OF RESEARCH, IT APPEARS I AM NOT THE ONLY ONE HAVING THIS ISSUE. I HAVE ALSO REACHED OUT TO SEVERAL NEWS MEADIA OUTLETS TO ASSURE THIS IS ADDRESSED TO PREVENT BY FAMILY GETTING HURT AND/OR KILLED DUE TO THE FAILURE OF THE 6L80 TRANSMISSION PROBLEMS. PLEASE TAKE INTO CONSIDERATIONS OF THE SERIOUNESS OF THIS ISSUE. THE VEHICLE NEEDS A NEW TRANSMISSION THAT I CAN NOT AFFORD. THE VEHICLE HAS NO CODES/WARNING DISPLAYED ON THE DASH WHICH PUTS MY FAMNILT AND I AT RISK WHEN DRIVING.
