NHTSA Complaint #11243019 — 2015 CHEVROLET SUBURBAN

TRANSMISSION WAS SHIFTING 'ROUGHLY' BOTH IN ACCELERATING AND DECELERATING CONDITIONS. SO ROUGH THAT MOVEMENT WITHIN THE VEHICLE WAS EXPERIENCED BY DRIVER AND PASSENGERS. WHEN THE VEHICLE WAS UNDERGOING BRAKING AND DECELERATING CONDITIONS THE VEHICLE WOULD ALSO MAKE NOISE AS SHIFTS OCCURRED IN THE TRANSMISSION (LOUD BANGING OR KNOCKING SOUNDS WERE HEARD). THE VEHICLE WAS MAINTAINED ACCORDING TO MANUFACTURERS RECOMMENDATION. EVENTUALLY THE TRANSMISSION EXPERIENCED MORE UNSAFE CONDITIONS WHEN GEARS WOULD NOT ENGAGE DURING ACCELERATION. THE VEHICLE WOULD ROLL BACKWARDS ON INCLINED SURFACES FOR SEVERAL INCHES TO SEVERAL FEET BEFORE TRANSMISSION ENGAGEMENT. IF TRAFFIC WAS BEHIND ON ANY INCLINE THE DRIVER WOULD HAVE TO USE BRAKE TO PREVENT ROLLING BACKWARD AND MAKING IMPACT WITH VEHICLE BEHIND.
