2017 CHRYSLER 200 Power Trainautomatic Transmission Problems

I PURCHASED A 2017 CHRYSLER 200 LIMITED FROM STEVE LANDER'S CHRYSLER DODGE JEEP FEBRUARY 12, 2018. ON FEBRUARY 24,2018 I HAD TO RETURN MY VEHICLE DO TO MY VEHICLE ACCELERATING ON IT'S OWN WHEN MY FOOT WAS REMOVED FROM THE BRAKE PEDAL. UPON ACCELERATING MY GAS GUSHER WOULD DROP A NOT H EACH TIME. FEBRUARY 23, 2018 MY VEHICLE DID AN UPDATE THAT NIGHT; THAT AT WHEN IT STARTED. I CALLED THE DEALERSHIP THE SAME NIGHT AND TALK WITH EMIL THE FINANCE MANAGER. HE TOLD ME TO BRING IT IN THE NEXT DAY. WHICH WAS FEBRUARY 24, 2018. MY I WAS TOLD IT WAS READY ONE WEEK LATER SO I GO TO PICK IT UP. THE PROBLEM WASN'T FIXED. I LEFT IT THERE. I RECEIVED A PHONE CALL FROM MELINDA SAYING A TECHNICIAN DROVE MY CAR AND THE TRANSMISSION SLAMMED SO HARD THE TECH THOUGHT IT FELL OUT THE VEHICLE....
