NHTSA Complaint #11388624 — 2015 CHEVROLET TRAVERSE

I COME TO A STOP THEN MY SUV STARTS TO SHAKE THEN TURNS OFF AS I AM AT A LIGHT OR ABOUT TO TURN AT A STOP. WHEN I PUSH AN THE GAS PEDAL THE WHOLE SUV SHAKES AND SOMETIMES THE CHECK ENGINE LIGHT TURNS ON RIGHT BEFORE THE WHOLE CAR JUST TURN OFF WHEN I COME TO A STOP. I'VE HAD ALL 4 CO2 SENSORS CHANGED. EVERYTHING THE DEALERSHIP HAS TOLD ME TO FIX I HAVE PAID TO HAVE DONE ON MY CAR. AND YET MY PROBLEM IS THE SAME THING FOR THE PAST 3 YEARS. I COULDN'T RETURN IT BECAUSE I WAITED TO LONG AFTER MY WARRANTY. NOW I AM TOLD TO KEEP PAYING FOR SERVICES I HAVE ALREADY PAID TO HAVE DONE. EVEN THOUGH IT HAPPENS TO BE THE SAME THING THE SYSTEM IS SHOWING UP ON THE COMPUTER. I HAVE A LEMON ON MY HANDS AND NEED HELP FIGURING OUT WHAT CAN BE DONE TO FIX THIS.
